87429387 divided by 629 
Our goal is to divide 87429387 by 629.

Step 1:
The number 629 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 629

Going ahead to step 2:
629 can be fit into 87 0 times, resulting in a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Fetch the next digit (4) from the dividend, attach it to 87 and continue: 874 / 629

Advancing to step 3:
When dividing 874 by 629, we get 1 with a remainder of 245.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 629 from 874, we get 245.
Append the next digit (2) from the dividend to 245 and continue with: 2452 / 629

Step 4:
629 goes into 2452 3 times with a remainder of 565.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtract 1887 from 2452 to get 565.
Fetch the next digit (9) from the dividend, attach it to 565 and continue: 5659 / 629

On to step 5:
The number 629 fits into 5659 8 times, leaving a remainder of 627.
Put 8 as the next digit of the answer. 
Result so far: 138.0
If we subtract 5032 from 5659, we get 627.
Append the next digit (3) from the dividend to 627 and continue with: 6273 / 629

Let's proceed to step 6:
629 goes into 6273 9 times with a remainder of 612.
Put 9 as the next digit of the answer. 
Result so far: 1389.0
The remainder is 612 after subtracting 5661 from 6273.
Bring next digit (8) of the dividend behind the 612 and repeat the process: 6128 / 629

Let's proceed to step 7:
When dividing 6128 by 629, we get 9 with a remainder of 467.
The next digit of our result is 9. 
Result so far: 13899.0
Subtract 5661 from 6128 to get 467.
Bring next digit (7) of the dividend behind the 467 and repeat the process: 4677 / 629

Let's proceed to step 8:
629 can be fit into 4677 7 times, resulting in a remainder of 274.
The next digit of our result is 7. 
Result so far: 138997.0
If we take 4403 away from 4677, we end up with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

On to step 9:
If we divide 2740 by 629, we get 4 and a remainder of 224.
Record the quotient 4 as the next digit in the result. 
Result so far: 138997.4
Subtract 2516 from 2740 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Moving on to step 10:
The number 629 fits into 2240 3 times, leaving a remainder of 353.
Write down 3 as next digit of the result. 
Result so far: 138997.43
The remainder is 353 after subtracting 1887 from 2240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Advancing to step 11:
The number 629 fits into 3530 5 times, leaving a remainder of 385.
The next digit of our result is 5. 
Result so far: 138997.435
Subtract 3145 from 3530 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.

Moving on to step 12:
629 goes into 3850 6 times with a remainder of 76.
The number 6 becomes the next digit in our result. 
Result so far: 138997.4356
The remainder is 76 after subtracting 3774 from 3850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 13:
The number 629 fits into 760 1 times, leaving a remainder of 131.
The number 1 becomes the next digit in our result. 
Result so far: 138997.43561
Subtracting 629 from 760 leaves us with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Step 14:
629 goes into 1310 2 times with a remainder of 52.
Record the quotient 2 as the next digit in the result. 
Result so far: 138997.435612
Subtract 1258 from 1310 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 15:
The number 629 fits into 520 0 times, leaving a remainder of 520.
The number 0 becomes the next digit in our result. 
Result so far: 138997.435612
The remainder is 520 after subtracting 0 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Advancing to step 16:
629 goes into 5200 8 times with a remainder of 168.
The next digit of our result is 8. 
Result so far: 138997.43561208
If we take 5032 away from 5200, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

The final outcome is 138997.43561208, with a leftover of 1.68e-07.
