Let's divide 398072 by 28
We're looking to find how many times 28 goes into 398072.

On to step 1:
The number 28 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 28

Let's proceed to step 2:
28 goes into 39 1 times with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 28 away from 39, we end up with 11.
Take the next digit (8) from the dividend and append it to 11, then repeat: 118 / 28

On to step 3:
The number 28 fits into 118 4 times, leaving a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we take 112 away from 118, we end up with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 28

Let's proceed to step 4:
60 divided by 28 is 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 142.0
If we take 56 away from 60, we end up with 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 28

On to step 5:
If we divide 47 by 28, we get 1 and a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 1421.0
Subtracting 28 from 47 leaves us with 19.
Fetch the next digit (2) from the dividend, attach it to 19 and continue: 192 / 28

Moving on to step 6:
If we divide 192 by 28, we get 6 and a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 14216.0
If we subtract 168 from 192, 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.

Moving on to step 7:
When dividing 240 by 28, we get 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 14216.8
Deduct 224 from 240 and we're left 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.

Moving on to step 8:
160 divided by 28 is 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 14216.85
Deduct 140 from 160 and we're left 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.

Going ahead to step 9:
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: 14216.857
Deduct 196 from 200 and we're left 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 10:
28 goes into 40 1 times with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 14216.8571
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 11:
If we divide 120 by 28, we get 4 and a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 14216.85714
Subtract 112 from 120 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

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: 14216.857142
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.

Let's proceed to step 13:
28 goes into 240 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 14216.8571428
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.

Moving on to step 14:
If we divide 160 by 28, we get 5 and a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 14216.85714285
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.

The final outcome is 14216.85714285, with a leftover of 2e-08.
