40385196 ÷ 629 
We want to divide 40385196 by 629.

Step 1:
If we divide 4 by 629, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 629

Moving on to step 2:
When dividing 40 by 629, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Bring next digit (3) of the dividend behind the 40 and repeat the process: 403 / 629

Step 3:
403 divided by 629 is 0 with a remainder of 403.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 403 to get 403.
Grab the next digit (8) from the dividend, add it to 403, then carry on: 4038 / 629

On to step 4:
4038 divided by 629 is 6 with a remainder of 264.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 264 after subtracting 3774 from 4038.
Fetch the next digit (5) from the dividend, attach it to 264 and continue: 2645 / 629

Advancing to step 5:
629 can be fit into 2645 4 times, resulting in a remainder of 129.
Put 4 as the next digit of the answer. 
Result so far: 64.0
Subtract 2516 from 2645 to get 129.
Grab the next digit (1) from the dividend, add it to 129, then carry on: 1291 / 629

Step 6:
The number 629 fits into 1291 2 times, leaving a remainder of 33.
Record the quotient 2 as the next digit in the result. 
Result so far: 642.0
Deduct 1258 from 1291 and we're left with 33.
Include the next digit (9) from the dividend after 33, then repeat: 339 / 629

Advancing to step 7:
When dividing 339 by 629, we get 0 with a remainder of 339.
Put 0 as the next digit of the answer. 
Result so far: 6420.0
If we subtract 0 from 339, we get 339.
Append the next digit (6) from the dividend to 339 and continue with: 3396 / 629

Step 8:
3396 divided by 629 is 5 with a remainder of 251.
Use 5 as the next digit of our solution. 
Result so far: 64205.0
If we take 3145 away from 3396, we end up with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

On to step 9:
The number 629 fits into 2510 3 times, leaving a remainder of 623.
Put 3 as the next digit of the answer. 
Result so far: 64205.3
Deduct 1887 from 2510 and we're left with 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

On to step 10:
629 can be fit into 6230 9 times, resulting in a remainder of 569.
The next digit of our result is 9. 
Result so far: 64205.39
If we take 5661 away from 6230, we end up with 569.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5690, and continue the process.

On to step 11:
5690 divided by 629 is 9 with a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 64205.399
If we take 5661 away from 5690, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

After the division, we end up with 64205.399 and a remainder of 0.0029.
