Let's divide 47386078 by 645
Our goal is to divide 47386078 by 645.

Going ahead to step 1:
If we divide 4 by 645, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 645

Going ahead to step 2:
When dividing 47 by 645, we get 0 with a remainder of 47.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 47, we get 47.
Fetch the next digit (3) from the dividend, attach it to 47 and continue: 473 / 645

Step 3:
645 can be fit into 473 0 times, resulting in a remainder of 473.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 473 to get 473.
Fetch the next digit (8) from the dividend, attach it to 473 and continue: 4738 / 645

Moving on to step 4:
When dividing 4738 by 645, we get 7 with a remainder of 223.
The next digit of our result is 7. 
Result so far: 7.0
If we take 4515 away from 4738, we end up with 223.
Include the next digit (6) from the dividend after 223, then repeat: 2236 / 645

Let's proceed to step 5:
2236 divided by 645 is 3 with a remainder of 301.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
If we take 1935 away from 2236, we end up with 301.
Take the next digit (0) from the dividend and append it to 301, then repeat: 3010 / 645

On to step 6:
645 goes into 3010 4 times with a remainder of 430.
Record the quotient 4 as the next digit in the result. 
Result so far: 734.0
If we subtract 2580 from 3010, we get 430.
Include the next digit (7) from the dividend after 430, then repeat: 4307 / 645

Going ahead to step 7:
When dividing 4307 by 645, we get 6 with a remainder of 437.
Record the quotient 6 as the next digit in the result. 
Result so far: 7346.0
If we take 3870 away from 4307, we end up with 437.
Grab the next digit (8) from the dividend, add it to 437, then carry on: 4378 / 645

Let's proceed to step 8:
When dividing 4378 by 645, we get 6 with a remainder of 508.
Use 6 as the next digit of our solution. 
Result so far: 73466.0
Deduct 3870 from 4378 and we're left 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.

Moving on to step 9:
When dividing 5080 by 645, we get 7 with a remainder of 565.
Record the quotient 7 as the next digit in the result. 
Result so far: 73466.7
If we subtract 4515 from 5080, we get 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Going ahead to step 10:
The number 645 fits into 5650 8 times, leaving a remainder of 490.
Write down 8 as next digit of the result. 
Result so far: 73466.78
If we take 5160 away from 5650, we end up with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Let's proceed to step 11:
645 can be fit into 4900 7 times, resulting in a remainder of 385.
The next digit of our result is 7. 
Result so far: 73466.787
Subtract 4515 from 4900 to get 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Advancing to step 12:
If we divide 3850 by 645, we get 5 and a remainder of 625.
The next digit of our result is 5. 
Result so far: 73466.7875
Deduct 3225 from 3850 and we're left with 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Advancing to step 13:
6250 divided by 645 is 9 with a remainder of 445.
The next digit of our result is 9. 
Result so far: 73466.78759
If we take 5805 away from 6250, we end up with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Let's proceed to step 14:
The number 645 fits into 4450 6 times, leaving a remainder of 580.
Use 6 as the next digit of our solution. 
Result so far: 73466.787596
If we take 3870 away from 4450, we end up with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

On to step 15:
645 can be fit into 5800 8 times, resulting in a remainder of 640.
Put 8 as the next digit of the answer. 
Result so far: 73466.7875968
If we take 5160 away from 5800, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Step 16:
When dividing 6400 by 645, we get 9 with a remainder of 595.
Put 9 as the next digit of the answer. 
Result so far: 73466.78759689
If we subtract 5805 from 6400, we get 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

After the division, we end up with 73466.78759689 and a remainder of 5.95e-07.
