We're dividing 86289819 by 318 
We want to divide 86289819 by 318.

On to step 1:
8 divided by 318 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 318

On to step 2:
318 goes into 86 0 times with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Append the next digit (2) from the dividend to 86 and continue with: 862 / 318

Going ahead to step 3:
When dividing 862 by 318, we get 2 with a remainder of 226.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 636 from 862 leaves us with 226.
Grab the next digit (8) from the dividend, add it to 226, then carry on: 2268 / 318

Advancing to step 4:
2268 divided by 318 is 7 with a remainder of 42.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
The remainder is 42 after subtracting 2226 from 2268.
Grab the next digit (9) from the dividend, add it to 42, then carry on: 429 / 318

Advancing to step 5:
318 can be fit into 429 1 times, resulting in a remainder of 111.
Put 1 as the next digit of the answer. 
Result so far: 271.0
The remainder is 111 after subtracting 318 from 429.
Take the next digit (8) from the dividend and append it to 111, then repeat: 1118 / 318

Let's proceed to step 6:
If we divide 1118 by 318, we get 3 and a remainder of 164.
Write down 3 as next digit of the result. 
Result so far: 2713.0
Subtract 954 from 1118 to get 164.
Grab the next digit (1) from the dividend, add it to 164, then carry on: 1641 / 318

Moving on to step 7:
If we divide 1641 by 318, we get 5 and a remainder of 51.
The next digit of our result is 5. 
Result so far: 27135.0
Deduct 1590 from 1641 and we're left with 51.
Take the next digit (9) from the dividend and append it to 51, then repeat: 519 / 318

On to step 8:
318 can be fit into 519 1 times, resulting in a remainder of 201.
The next digit of our result is 1. 
Result so far: 271351.0
Subtract 318 from 519 to get 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Moving on to step 9:
318 can be fit into 2010 6 times, resulting in a remainder of 102.
Record the quotient 6 as the next digit in the result. 
Result so far: 271351.6
If we take 1908 away from 2010, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Step 10:
If we divide 1020 by 318, we get 3 and a remainder of 66.
Put 3 as the next digit of the answer. 
Result so far: 271351.63
If we take 954 away from 1020, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 11:
When dividing 660 by 318, we get 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 271351.632
If we subtract 636 from 660, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
318 can be fit into 240 0 times, resulting in a remainder of 240.
The next digit of our result is 0. 
Result so far: 271351.632
If we take 0 away from 240, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 13:
318 can be fit into 2400 7 times, resulting in a remainder of 174.
The next digit of our result is 7. 
Result so far: 271351.63207
Subtract 2226 from 2400 to get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Let's proceed to step 14:
If we divide 1740 by 318, we get 5 and a remainder of 150.
Put 5 as the next digit of the answer. 
Result so far: 271351.632075
The remainder is 150 after subtracting 1590 from 1740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 15:
When dividing 1500 by 318, we get 4 with a remainder of 228.
Write down 4 as next digit of the result. 
Result so far: 271351.6320754
Deduct 1272 from 1500 and we're left with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Moving on to step 16:
318 can be fit into 2280 7 times, resulting in a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 271351.63207547
Subtract 2226 from 2280 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The quotient of the division is 271351.63207547, and the remainder is 5.4e-08.
