Let's divide 87203963 by 629
We're looking to find how many times 629 goes into 87203963.

Step 1:
The number 629 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 629

Let's proceed to step 2:
87 divided by 629 is 0 with a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Take the next digit (2) from the dividend and append it to 87, then repeat: 872 / 629

Advancing to step 3:
When dividing 872 by 629, we get 1 with a remainder of 243.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 629 from 872 to get 243.
Bring next digit (0) of the dividend behind the 243 and repeat the process: 2430 / 629

On to step 4:
If we divide 2430 by 629, we get 3 and a remainder of 543.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we subtract 1887 from 2430, we get 543.
Bring next digit (3) of the dividend behind the 543 and repeat the process: 5433 / 629

Going ahead to step 5:
If we divide 5433 by 629, we get 8 and a remainder of 401.
Record the quotient 8 as the next digit in the result. 
Result so far: 138.0
If we subtract 5032 from 5433, we get 401.
Append the next digit (9) from the dividend to 401 and continue with: 4019 / 629

Advancing to step 6:
When dividing 4019 by 629, we get 6 with a remainder of 245.
Write down 6 as next digit of the result. 
Result so far: 1386.0
If we subtract 3774 from 4019, we get 245.
Include the next digit (6) from the dividend after 245, then repeat: 2456 / 629

Moving on to step 7:
If we divide 2456 by 629, we get 3 and a remainder of 569.
Put 3 as the next digit of the answer. 
Result so far: 13863.0
If we subtract 1887 from 2456, we get 569.
Take the next digit (3) from the dividend and append it to 569, then repeat: 5693 / 629

On to step 8:
If we divide 5693 by 629, we get 9 and a remainder of 32.
Record the quotient 9 as the next digit in the result. 
Result so far: 138639.0
The remainder is 32 after subtracting 5661 from 5693.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 9:
When dividing 320 by 629, we get 0 with a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 138639.0
The remainder is 320 after subtracting 0 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 10:
When dividing 3200 by 629, we get 5 with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 138639.05
The remainder is 55 after subtracting 3145 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 11:
550 divided by 629 is 0 with a remainder of 550.
Record the quotient 0 as the next digit in the result. 
Result so far: 138639.05
The remainder is 550 after subtracting 0 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Moving on to step 12:
629 goes into 5500 8 times with a remainder of 468.
The next digit of our result is 8. 
Result so far: 138639.0508
Subtract 5032 from 5500 to get 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Advancing to step 13:
4680 divided by 629 is 7 with a remainder of 277.
Use 7 as the next digit of our solution. 
Result so far: 138639.05087
If we take 4403 away from 4680, we end up with 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Going ahead to step 14:
If we divide 2770 by 629, we get 4 and a remainder of 254.
Write down 4 as next digit of the result. 
Result so far: 138639.050874
Subtracting 2516 from 2770 leaves us with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

On to step 15:
629 goes into 2540 4 times with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 138639.0508744
The remainder is 24 after subtracting 2516 from 2540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 138639.0508744 with a remainder of 2.4e-07.
