We're dividing 87098309 by 315 
We want to divide 87098309 by 315.

On to step 1:
315 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 315

Let's proceed to step 2:
315 can be fit into 87 0 times, resulting in a remainder of 87.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Append the next digit (0) from the dividend to 87 and continue with: 870 / 315

Going ahead to step 3:
315 goes into 870 2 times with a remainder of 240.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 630 from 870 leaves us with 240.
Take the next digit (9) from the dividend and append it to 240, then repeat: 2409 / 315

Moving on to step 4:
If we divide 2409 by 315, we get 7 and a remainder of 204.
The next digit of our result is 7. 
Result so far: 27.0
Subtracting 2205 from 2409 leaves us with 204.
Take the next digit (8) from the dividend and append it to 204, then repeat: 2048 / 315

Let's proceed to step 5:
When dividing 2048 by 315, we get 6 with a remainder of 158.
Write down 6 as next digit of the result. 
Result so far: 276.0
If we take 1890 away from 2048, we end up with 158.
Take the next digit (3) from the dividend and append it to 158, then repeat: 1583 / 315

Advancing to step 6:
The number 315 fits into 1583 5 times, leaving a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 2765.0
The remainder is 8 after subtracting 1575 from 1583.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 315

Let's proceed to step 7:
If we divide 80 by 315, we get 0 and a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 27650.0
Subtract 0 from 80 to get 80.
Fetch the next digit (9) from the dividend, attach it to 80 and continue: 809 / 315

Moving on to step 8:
If we divide 809 by 315, we get 2 and a remainder of 179.
Use 2 as the next digit of our solution. 
Result so far: 276502.0
If we take 630 away from 809, we end up with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Going ahead to step 9:
If we divide 1790 by 315, we get 5 and a remainder of 215.
Put 5 as the next digit of the answer. 
Result so far: 276502.5
If we subtract 1575 from 1790, we get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Step 10:
The number 315 fits into 2150 6 times, leaving a remainder of 260.
Write down 6 as next digit of the result. 
Result so far: 276502.56
The remainder is 260 after subtracting 1890 from 2150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 11:
315 goes into 2600 8 times with a remainder of 80.
Put 8 as the next digit of the answer. 
Result so far: 276502.568
If we subtract 2520 from 2600, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 12:
800 divided by 315 is 2 with a remainder of 170.
Write down 2 as next digit of the result. 
Result so far: 276502.5682
If we take 630 away from 800, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 13:
315 goes into 1700 5 times with a remainder of 125.
The number 5 becomes the next digit in our result. 
Result so far: 276502.56825
The remainder is 125 after subtracting 1575 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 14:
1250 divided by 315 is 3 with a remainder of 305.
Use 3 as the next digit of our solution. 
Result so far: 276502.568253
Subtracting 945 from 1250 leaves us with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Going ahead to step 15:
If we divide 3050 by 315, we get 9 and a remainder of 215.
Put 9 as the next digit of the answer. 
Result so far: 276502.5682539
If we take 2835 away from 3050, we end up with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Step 16:
If we divide 2150 by 315, we get 6 and a remainder of 260.
The next digit of our result is 6. 
Result so far: 276502.56825396
The remainder is 260 after subtracting 1890 from 2150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

After the division, we end up with 276502.56825396 and a remainder of 2.6e-07.
