We're dividing 54019259 by 668 
We want to divide 54019259 by 668.

On to step 1:
The number 668 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 668

Advancing to step 2:
54 divided by 668 is 0 with a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 54 leaves us with 54.
Include the next digit (0) from the dividend after 54, then repeat: 540 / 668

Going ahead to step 3:
668 can be fit into 540 0 times, resulting in a remainder of 540.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 540, we get 540.
Append the next digit (1) from the dividend to 540 and continue with: 5401 / 668

Let's proceed to step 4:
668 goes into 5401 8 times with a remainder of 57.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 5344 away from 5401, we end up with 57.
Append the next digit (9) from the dividend to 57 and continue with: 579 / 668

Moving on to step 5:
If we divide 579 by 668, we get 0 and a remainder of 579.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
If we take 0 away from 579, we end up with 579.
Bring next digit (2) of the dividend behind the 579 and repeat the process: 5792 / 668

On to step 6:
5792 divided by 668 is 8 with a remainder of 448.
Record the quotient 8 as the next digit in the result. 
Result so far: 808.0
Deduct 5344 from 5792 and we're left with 448.
Append the next digit (5) from the dividend to 448 and continue with: 4485 / 668

Let's proceed to step 7:
668 can be fit into 4485 6 times, resulting in a remainder of 477.
The number 6 becomes the next digit in our result. 
Result so far: 8086.0
Subtracting 4008 from 4485 leaves us with 477.
Bring next digit (9) of the dividend behind the 477 and repeat the process: 4779 / 668

On to step 8:
4779 divided by 668 is 7 with a remainder of 103.
Write down 7 as next digit of the result. 
Result so far: 80867.0
Subtracting 4676 from 4779 leaves us with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Let's proceed to step 9:
668 goes into 1030 1 times with a remainder of 362.
Use 1 as the next digit of our solution. 
Result so far: 80867.1
Deduct 668 from 1030 and we're left with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Let's proceed to step 10:
The number 668 fits into 3620 5 times, leaving a remainder of 280.
The number 5 becomes the next digit in our result. 
Result so far: 80867.15
Deduct 3340 from 3620 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 11:
668 goes into 2800 4 times with a remainder of 128.
The number 4 becomes the next digit in our result. 
Result so far: 80867.154
If we take 2672 away from 2800, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 12:
If we divide 1280 by 668, we get 1 and a remainder of 612.
Use 1 as the next digit of our solution. 
Result so far: 80867.1541
Deduct 668 from 1280 and we're left with 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Step 13:
If we divide 6120 by 668, we get 9 and a remainder of 108.
The next digit of our result is 9. 
Result so far: 80867.15419
Subtract 6012 from 6120 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

On to step 14:
668 can be fit into 1080 1 times, resulting in a remainder of 412.
Write down 1 as next digit of the result. 
Result so far: 80867.154191
If we subtract 668 from 1080, we get 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Moving on to step 15:
If we divide 4120 by 668, we get 6 and a remainder of 112.
The next digit of our result is 6. 
Result so far: 80867.1541916
Deduct 4008 from 4120 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 16:
If we divide 1120 by 668, we get 1 and a remainder of 452.
The next digit of our result is 1. 
Result so far: 80867.15419161
If we subtract 668 from 1120, we get 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

After the division, we end up with 80867.15419161 and a remainder of 4.52e-07.
