We look at the division of 86913388 by 285 
We're looking to find how many times 285 goes into 86913388.

Moving on to step 1:
The number 285 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 285

On to step 2:
When dividing 86 by 285, we get 0 with a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Bring next digit (9) of the dividend behind the 86 and repeat the process: 869 / 285

Let's proceed to step 3:
The number 285 fits into 869 3 times, leaving a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 855 from 869 to get 14.
Grab the next digit (1) from the dividend, add it to 14, then carry on: 141 / 285

Let's proceed to step 4:
If we divide 141 by 285, we get 0 and a remainder of 141.
The next digit of our result is 0. 
Result so far: 30.0
If we subtract 0 from 141, we get 141.
Take the next digit (3) from the dividend and append it to 141, then repeat: 1413 / 285

Step 5:
If we divide 1413 by 285, we get 4 and a remainder of 273.
Put 4 as the next digit of the answer. 
Result so far: 304.0
Subtracting 1140 from 1413 leaves us with 273.
Fetch the next digit (3) from the dividend, attach it to 273 and continue: 2733 / 285

Moving on to step 6:
The number 285 fits into 2733 9 times, leaving a remainder of 168.
The next digit of our result is 9. 
Result so far: 3049.0
The remainder is 168 after subtracting 2565 from 2733.
Grab the next digit (8) from the dividend, add it to 168, then carry on: 1688 / 285

Let's proceed to step 7:
The number 285 fits into 1688 5 times, leaving a remainder of 263.
The next digit of our result is 5. 
Result so far: 30495.0
Subtracting 1425 from 1688 leaves us with 263.
Append the next digit (8) from the dividend to 263 and continue with: 2638 / 285

Advancing to step 8:
The number 285 fits into 2638 9 times, leaving a remainder of 73.
Record the quotient 9 as the next digit in the result. 
Result so far: 304959.0
Subtracting 2565 from 2638 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 9:
285 goes into 730 2 times with a remainder of 160.
Use 2 as the next digit of our solution. 
Result so far: 304959.2
Subtract 570 from 730 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 10:
If we divide 1600 by 285, we get 5 and a remainder of 175.
Record the quotient 5 as the next digit in the result. 
Result so far: 304959.25
If we take 1425 away from 1600, we end up with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Step 11:
285 can be fit into 1750 6 times, resulting in a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 304959.256
The remainder is 40 after subtracting 1710 from 1750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
400 divided by 285 is 1 with a remainder of 115.
Record the quotient 1 as the next digit in the result. 
Result so far: 304959.2561
Deduct 285 from 400 and we're left with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 13:
If we divide 1150 by 285, we get 4 and a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 304959.25614
The remainder is 10 after subtracting 1140 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
If we divide 100 by 285, we get 0 and a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 304959.25614
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 15:
285 can be fit into 1000 3 times, resulting in a remainder of 145.
The number 3 becomes the next digit in our result. 
Result so far: 304959.2561403
Subtract 855 from 1000 to get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

On to step 16:
When dividing 1450 by 285, we get 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 304959.25614035
Subtracting 1425 from 1450 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 304959.25614035 and a remainder of 2.5e-08.
