We divide 398557 by 28
We want to divide 398557 by 28.

On to step 1:
28 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 28

Moving on to step 2:
28 goes into 39 1 times with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 11 after subtracting 28 from 39.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 28

Moving on to step 3:
The number 28 fits into 118 4 times, leaving a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we take 112 away from 118, we end up with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 28

Moving on to step 4:
28 goes into 65 2 times with a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 142.0
The remainder is 9 after subtracting 56 from 65.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 28

Going ahead to step 5:
The number 28 fits into 95 3 times, leaving a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 1423.0
Deduct 84 from 95 and we're left with 11.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 28

Advancing to step 6:
If we divide 117 by 28, we get 4 and a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 14234.0
Subtract 112 from 117 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
28 can be fit into 50 1 times, resulting in a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 14234.1
Subtracting 28 from 50 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.

Going ahead to step 8:
The number 28 fits into 220 7 times, leaving a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 14234.17
If we take 196 away from 220, we end up 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.

On to step 9:
28 can be fit into 240 8 times, resulting in a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 14234.178
If we take 224 away from 240, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
The number 28 fits into 160 5 times, leaving a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 14234.1785
Subtracting 140 from 160 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 11:
200 divided by 28 is 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 14234.17857
If we take 196 away from 200, we end up 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.

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: 14234.178571
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.

On to step 13:
When dividing 120 by 28, we get 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 14234.1785714
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.

On to step 14:
28 can be fit into 80 2 times, resulting in a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 14234.17857142
If we subtract 56 from 80, 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.

Our division results in 14234.17857142 with a remaining 2.4e-08.
