87128285 ÷ 630 
Our goal is to divide 87128285 by 630.

Advancing to step 1:
The number 630 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 630

Going ahead to step 2:
The number 630 fits into 87 0 times, leaving a remainder of 87.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Take the next digit (1) from the dividend and append it to 87, then repeat: 871 / 630

On to step 3:
630 goes into 871 1 times with a remainder of 241.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 630 from 871 and we're left with 241.
Include the next digit (2) from the dividend after 241, then repeat: 2412 / 630

Let's proceed to step 4:
The number 630 fits into 2412 3 times, leaving a remainder of 522.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 1890 from 2412 and we're left with 522.
Take the next digit (8) from the dividend and append it to 522, then repeat: 5228 / 630

Let's proceed to step 5:
630 can be fit into 5228 8 times, resulting in a remainder of 188.
The number 8 becomes the next digit in our result. 
Result so far: 138.0
Deduct 5040 from 5228 and we're left with 188.
Bring next digit (2) of the dividend behind the 188 and repeat the process: 1882 / 630

Advancing to step 6:
630 can be fit into 1882 2 times, resulting in a remainder of 622.
The number 2 becomes the next digit in our result. 
Result so far: 1382.0
Deduct 1260 from 1882 and we're left with 622.
Include the next digit (8) from the dividend after 622, then repeat: 6228 / 630

Advancing to step 7:
When dividing 6228 by 630, we get 9 with a remainder of 558.
The next digit of our result is 9. 
Result so far: 13829.0
Subtracting 5670 from 6228 leaves us with 558.
Take the next digit (5) from the dividend and append it to 558, then repeat: 5585 / 630

Step 8:
The number 630 fits into 5585 8 times, leaving a remainder of 545.
The next digit of our result is 8. 
Result so far: 138298.0
Deduct 5040 from 5585 and we're left with 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

On to step 9:
If we divide 5450 by 630, we get 8 and a remainder of 410.
Write down 8 as next digit of the result. 
Result so far: 138298.8
Deduct 5040 from 5450 and we're left with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Going ahead to step 10:
The number 630 fits into 4100 6 times, leaving a remainder of 320.
The next digit of our result is 6. 
Result so far: 138298.86
If we take 3780 away from 4100, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 11:
If we divide 3200 by 630, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 138298.865
If we subtract 3150 from 3200, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 12:
630 goes into 500 0 times with a remainder of 500.
Put 0 as the next digit of the answer. 
Result so far: 138298.865
If we take 0 away from 500, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

On to step 13:
630 can be fit into 5000 7 times, resulting in a remainder of 590.
The number 7 becomes the next digit in our result. 
Result so far: 138298.86507
Deduct 4410 from 5000 and we're left with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Step 14:
When dividing 5900 by 630, we get 9 with a remainder of 230.
Write down 9 as next digit of the result. 
Result so far: 138298.865079
If we take 5670 away from 5900, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 15:
630 goes into 2300 3 times with a remainder of 410.
The next digit of our result is 3. 
Result so far: 138298.8650793
Subtract 1890 from 2300 to get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

On to step 16:
4100 divided by 630 is 6 with a remainder of 320.
The next digit of our result is 6. 
Result so far: 138298.86507936
Subtracting 3780 from 4100 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

The quotient of the division is 138298.86507936, and the remainder is 3.2e-07.
