We're dividing 86820471 by 315 
We want to divide 86820471 by 315.

Moving on to step 1:
When dividing 8 by 315, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 315

On to step 2:
315 can be fit into 86 0 times, resulting in a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Include the next digit (8) from the dividend after 86, then repeat: 868 / 315

Moving on to step 3:
315 goes into 868 2 times with a remainder of 238.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 238 after subtracting 630 from 868.
Include the next digit (2) from the dividend after 238, then repeat: 2382 / 315

Going ahead to step 4:
The number 315 fits into 2382 7 times, leaving a remainder of 177.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
Subtract 2205 from 2382 to get 177.
Take the next digit (0) from the dividend and append it to 177, then repeat: 1770 / 315

Going ahead to step 5:
315 goes into 1770 5 times with a remainder of 195.
Record the quotient 5 as the next digit in the result. 
Result so far: 275.0
Subtracting 1575 from 1770 leaves us with 195.
Grab the next digit (4) from the dividend, add it to 195, then carry on: 1954 / 315

Step 6:
The number 315 fits into 1954 6 times, leaving a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 2756.0
If we subtract 1890 from 1954, we get 64.
Fetch the next digit (7) from the dividend, attach it to 64 and continue: 647 / 315

On to step 7:
315 can be fit into 647 2 times, resulting in a remainder of 17.
Use 2 as the next digit of our solution. 
Result so far: 27562.0
The remainder is 17 after subtracting 630 from 647.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 315

Going ahead to step 8:
The number 315 fits into 171 0 times, leaving a remainder of 171.
Put 0 as the next digit of the answer. 
Result so far: 275620.0
If we take 0 away from 171, we end up with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Moving on to step 9:
If we divide 1710 by 315, we get 5 and a remainder of 135.
The number 5 becomes the next digit in our result. 
Result so far: 275620.5
Subtract 1575 from 1710 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Advancing to step 10:
If we divide 1350 by 315, we get 4 and a remainder of 90.
Put 4 as the next digit of the answer. 
Result so far: 275620.54
Subtracting 1260 from 1350 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 11:
If we divide 900 by 315, we get 2 and a remainder of 270.
The next digit of our result is 2. 
Result so far: 275620.542
Deduct 630 from 900 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Moving on to step 12:
The number 315 fits into 2700 8 times, leaving a remainder of 180.
Put 8 as the next digit of the answer. 
Result so far: 275620.5428
If we subtract 2520 from 2700, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 13:
315 can be fit into 1800 5 times, resulting in a remainder of 225.
The number 5 becomes the next digit in our result. 
Result so far: 275620.54285
Subtracting 1575 from 1800 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Advancing to step 14:
The number 315 fits into 2250 7 times, leaving a remainder of 45.
The number 7 becomes the next digit in our result. 
Result so far: 275620.542857
If we subtract 2205 from 2250, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 15:
450 divided by 315 is 1 with a remainder of 135.
The next digit of our result is 1. 
Result so far: 275620.5428571
If we take 315 away from 450, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Going ahead to step 16:
315 goes into 1350 4 times with a remainder of 90.
The next digit of our result is 4. 
Result so far: 275620.54285714
If we subtract 1260 from 1350, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Our division results in 275620.54285714 with a remaining 9e-08.
