288391 ÷ 28 
We want to divide 288391 by 28.

On to step 1:
2 divided by 28 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 28

Step 2:
If we divide 28 by 28, we get 1 and a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 0 after subtracting 28 from 28.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 28

Let's proceed to step 3:
28 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 28

Advancing to step 4:
28 goes into 83 2 times with a remainder of 27.
Use 2 as the next digit of our solution. 
Result so far: 102.0
Subtracting 56 from 83 leaves us with 27.
Grab the next digit (9) from the dividend, add it to 27, then carry on: 279 / 28

Going ahead to step 5:
279 divided by 28 is 9 with a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 1029.0
Subtracting 252 from 279 leaves us with 27.
Append the next digit (1) from the dividend to 27 and continue with: 271 / 28

Moving on to step 6:
The number 28 fits into 271 9 times, leaving a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 10299.0
Deduct 252 from 271 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
190 divided by 28 is 6 with a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 10299.6
Subtracting 168 from 190 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 8:
28 can be fit into 220 7 times, resulting in a remainder of 24.
Write down 7 as next digit of the result. 
Result so far: 10299.67
Deduct 196 from 220 and we're left with 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 9:
If we divide 240 by 28, we get 8 and a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 10299.678
Subtract 224 from 240 to 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.

Going ahead to step 10:
28 goes into 160 5 times with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 10299.6785
Subtract 140 from 160 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
The number 28 fits into 200 7 times, leaving a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 10299.67857
Subtract 196 from 200 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
40 divided by 28 is 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 10299.678571
Deduct 28 from 40 and we're left with 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 13:
If we divide 120 by 28, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 10299.6785714
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.

Moving on to step 14:
28 can be fit into 80 2 times, resulting in a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 10299.67857142
Deduct 56 from 80 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 10299.67857142, with a leftover of 2.4e-08.
