We look at the division of 45615629 by 668 
Let's see how many times 668 fits into 45615629.

Going ahead to step 1:
668 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 668

Moving on to step 2:
If we divide 45 by 668, we get 0 and a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Take the next digit (6) from the dividend and append it to 45, then repeat: 456 / 668

On to step 3:
668 can be fit into 456 0 times, resulting in a remainder of 456.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 456, we end up with 456.
Include the next digit (1) from the dividend after 456, then repeat: 4561 / 668

Let's proceed to step 4:
If we divide 4561 by 668, we get 6 and a remainder of 553.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 4008 from 4561 to get 553.
Grab the next digit (5) from the dividend, add it to 553, then carry on: 5535 / 668

Moving on to step 5:
When dividing 5535 by 668, we get 8 with a remainder of 191.
Write down 8 as next digit of the result. 
Result so far: 68.0
The remainder is 191 after subtracting 5344 from 5535.
Bring next digit (6) of the dividend behind the 191 and repeat the process: 1916 / 668

Let's proceed to step 6:
The number 668 fits into 1916 2 times, leaving a remainder of 580.
Record the quotient 2 as the next digit in the result. 
Result so far: 682.0
Deduct 1336 from 1916 and we're left with 580.
Grab the next digit (2) from the dividend, add it to 580, then carry on: 5802 / 668

Moving on to step 7:
If we divide 5802 by 668, we get 8 and a remainder of 458.
Record the quotient 8 as the next digit in the result. 
Result so far: 6828.0
If we subtract 5344 from 5802, we get 458.
Grab the next digit (9) from the dividend, add it to 458, then carry on: 4589 / 668

Let's proceed to step 8:
The number 668 fits into 4589 6 times, leaving a remainder of 581.
Use 6 as the next digit of our solution. 
Result so far: 68286.0
The remainder is 581 after subtracting 4008 from 4589.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5810, and continue the process.

Let's proceed to step 9:
The number 668 fits into 5810 8 times, leaving a remainder of 466.
The next digit of our result is 8. 
Result so far: 68286.8
The remainder is 466 after subtracting 5344 from 5810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Going ahead to step 10:
668 goes into 4660 6 times with a remainder of 652.
Use 6 as the next digit of our solution. 
Result so far: 68286.86
The remainder is 652 after subtracting 4008 from 4660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

Going ahead to step 11:
668 goes into 6520 9 times with a remainder of 508.
Put 9 as the next digit of the answer. 
Result so far: 68286.869
Subtracting 6012 from 6520 leaves us with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Let's proceed to step 12:
668 can be fit into 5080 7 times, resulting in a remainder of 404.
Use 7 as the next digit of our solution. 
Result so far: 68286.8697
If we subtract 4676 from 5080, we get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Let's proceed to step 13:
The number 668 fits into 4040 6 times, leaving a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 68286.86976
Deduct 4008 from 4040 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 14:
When dividing 320 by 668, we get 0 with a remainder of 320.
Record the quotient 0 as the next digit in the result. 
Result so far: 68286.86976
Subtracting 0 from 320 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 15:
668 can be fit into 3200 4 times, resulting in a remainder of 528.
The number 4 becomes the next digit in our result. 
Result so far: 68286.8697604
If we subtract 2672 from 3200, we get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Advancing to step 16:
When dividing 5280 by 668, we get 7 with a remainder of 604.
Put 7 as the next digit of the answer. 
Result so far: 68286.86976047
Subtracting 4676 from 5280 leaves us with 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

The final result is 68286.86976047 with a remainder of 6.04e-07.
