We're dividing 40403669 by 629 
We want to divide 40403669 by 629.

Going ahead to step 1:
When dividing 4 by 629, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 629

Let's proceed to step 2:
40 divided by 629 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Append the next digit (4) from the dividend to 40 and continue with: 404 / 629

On to step 3:
When dividing 404 by 629, we get 0 with a remainder of 404.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 404 leaves us with 404.
Take the next digit (0) from the dividend and append it to 404, then repeat: 4040 / 629

Going ahead to step 4:
629 can be fit into 4040 6 times, resulting in a remainder of 266.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 3774 from 4040 and we're left with 266.
Append the next digit (3) from the dividend to 266 and continue with: 2663 / 629

Moving on to step 5:
629 goes into 2663 4 times with a remainder of 147.
The next digit of our result is 4. 
Result so far: 64.0
Deduct 2516 from 2663 and we're left with 147.
Take the next digit (6) from the dividend and append it to 147, then repeat: 1476 / 629

Let's proceed to step 6:
If we divide 1476 by 629, we get 2 and a remainder of 218.
Record the quotient 2 as the next digit in the result. 
Result so far: 642.0
Subtract 1258 from 1476 to get 218.
Append the next digit (6) from the dividend to 218 and continue with: 2186 / 629

Advancing to step 7:
629 goes into 2186 3 times with a remainder of 299.
Use 3 as the next digit of our solution. 
Result so far: 6423.0
Deduct 1887 from 2186 and we're left with 299.
Fetch the next digit (9) from the dividend, attach it to 299 and continue: 2999 / 629

Step 8:
2999 divided by 629 is 4 with a remainder of 483.
Write down 4 as next digit of the result. 
Result so far: 64234.0
If we subtract 2516 from 2999, we get 483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

Advancing to step 9:
4830 divided by 629 is 7 with a remainder of 427.
The next digit of our result is 7. 
Result so far: 64234.7
The remainder is 427 after subtracting 4403 from 4830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

On to step 10:
When dividing 4270 by 629, we get 6 with a remainder of 496.
Write down 6 as next digit of the result. 
Result so far: 64234.76
If we subtract 3774 from 4270, we get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Let's proceed to step 11:
The number 629 fits into 4960 7 times, leaving a remainder of 557.
The number 7 becomes the next digit in our result. 
Result so far: 64234.767
The remainder is 557 after subtracting 4403 from 4960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5570, and continue the process.

Moving on to step 12:
If we divide 5570 by 629, we get 8 and a remainder of 538.
The number 8 becomes the next digit in our result. 
Result so far: 64234.7678
If we take 5032 away from 5570, we end up with 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Advancing to step 13:
The number 629 fits into 5380 8 times, leaving a remainder of 348.
Put 8 as the next digit of the answer. 
Result so far: 64234.76788
Subtracting 5032 from 5380 leaves us with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

In conclusion, the division gives 64234.76788 with a balance of 0.000348.
