86220259 divided by 28 
Our goal is to divide 86220259 by 28.

Step 1:
8 divided by 28 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 28

Step 2:
86 divided by 28 is 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 84 from 86 to get 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 28

Moving on to step 3:
28 can be fit into 22 0 times, resulting in a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 30.0
Deduct 0 from 22 and we're left with 22.
Append the next digit (2) from the dividend to 22 and continue with: 222 / 28

Advancing to step 4:
28 goes into 222 7 times with a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 307.0
If we subtract 196 from 222, we get 26.
Take the next digit (0) from the dividend and append it to 26, then repeat: 260 / 28

On to step 5:
28 can be fit into 260 9 times, resulting in a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 3079.0
Subtracting 252 from 260 leaves us with 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 28

Step 6:
28 goes into 82 2 times with a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 30792.0
Subtract 56 from 82 to get 26.
Take the next digit (5) from the dividend and append it to 26, then repeat: 265 / 28

Advancing to step 7:
If we divide 265 by 28, we get 9 and a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 307929.0
If we take 252 away from 265, we end up with 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 28

Going ahead to step 8:
28 goes into 139 4 times with a remainder of 27.
Put 4 as the next digit of the answer. 
Result so far: 3079294.0
The remainder is 27 after subtracting 112 from 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 9:
28 goes into 270 9 times with a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 3079294.9
Subtracting 252 from 270 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 10:
If we divide 180 by 28, we get 6 and a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 3079294.96
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 11:
28 can be fit into 120 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 3079294.964
Deduct 112 from 120 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
The number 28 fits into 80 2 times, leaving a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 3079294.9642
Subtract 56 from 80 to 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.

On to step 13:
The number 28 fits into 240 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 3079294.96428
If we subtract 224 from 240, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 14:
160 divided by 28 is 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 3079294.964285
The remainder is 20 after subtracting 140 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 15:
If we divide 200 by 28, we get 7 and a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 3079294.9642857
Subtracting 196 from 200 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 16:
28 can be fit into 40 1 times, resulting in a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 3079294.96428571
Subtract 28 from 40 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 3079294.96428571, and the remainder is 1.2e-08.
