Let's divide 87625851 by 630
We want to divide 87625851 by 630.

Step 1:
The number 630 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 630

Advancing to step 2:
If we divide 87 by 630, we get 0 and a remainder of 87.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Bring next digit (6) of the dividend behind the 87 and repeat the process: 876 / 630

Step 3:
630 goes into 876 1 times with a remainder of 246.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 630 from 876 and we're left with 246.
Grab the next digit (2) from the dividend, add it to 246, then carry on: 2462 / 630

Moving on to step 4:
When dividing 2462 by 630, we get 3 with a remainder of 572.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 572 after subtracting 1890 from 2462.
Fetch the next digit (5) from the dividend, attach it to 572 and continue: 5725 / 630

On to step 5:
630 can be fit into 5725 9 times, resulting in a remainder of 55.
The next digit of our result is 9. 
Result so far: 139.0
The remainder is 55 after subtracting 5670 from 5725.
Include the next digit (8) from the dividend after 55, then repeat: 558 / 630

On to step 6:
630 can be fit into 558 0 times, resulting in a remainder of 558.
Put 0 as the next digit of the answer. 
Result so far: 1390.0
If we take 0 away from 558, we end up with 558.
Fetch the next digit (5) from the dividend, attach it to 558 and continue: 5585 / 630

On to step 7:
5585 divided by 630 is 8 with a remainder of 545.
Use 8 as the next digit of our solution. 
Result so far: 13908.0
The remainder is 545 after subtracting 5040 from 5585.
Grab the next digit (1) from the dividend, add it to 545, then carry on: 5451 / 630

Going ahead to step 8:
630 goes into 5451 8 times with a remainder of 411.
Record the quotient 8 as the next digit in the result. 
Result so far: 139088.0
Subtract 5040 from 5451 to get 411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

On to step 9:
630 goes into 4110 6 times with a remainder of 330.
Use 6 as the next digit of our solution. 
Result so far: 139088.6
Subtracting 3780 from 4110 leaves us with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 10:
When dividing 3300 by 630, we get 5 with a remainder of 150.
Write down 5 as next digit of the result. 
Result so far: 139088.65
If we subtract 3150 from 3300, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 11:
The number 630 fits into 1500 2 times, leaving a remainder of 240.
Use 2 as the next digit of our solution. 
Result so far: 139088.652
The remainder is 240 after subtracting 1260 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 12:
When dividing 2400 by 630, we get 3 with a remainder of 510.
Record the quotient 3 as the next digit in the result. 
Result so far: 139088.6523
The remainder is 510 after subtracting 1890 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Advancing to step 13:
When dividing 5100 by 630, we get 8 with a remainder of 60.
Use 8 as the next digit of our solution. 
Result so far: 139088.65238
If we take 5040 away from 5100, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 14:
If we divide 600 by 630, we get 0 and a remainder of 600.
Write down 0 as next digit of the result. 
Result so far: 139088.65238
If we subtract 0 from 600, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 15:
If we divide 6000 by 630, we get 9 and a remainder of 330.
Write down 9 as next digit of the result. 
Result so far: 139088.6523809
The remainder is 330 after subtracting 5670 from 6000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Advancing to step 16:
630 goes into 3300 5 times with a remainder of 150.
Write down 5 as next digit of the result. 
Result so far: 139088.65238095
Subtracting 3150 from 3300 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Our division results in 139088.65238095 with a remaining 1.5e-07.
