We look at the division of 400893 by 28 
We want to divide 400893 by 28.

On to step 1:
If we divide 4 by 28, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 28

Let's proceed to step 2:
40 divided by 28 is 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 12 after subtracting 28 from 40.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 28

Going ahead to step 3:
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: 14.0
Subtract 112 from 120 to get 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 28

Advancing to step 4:
The number 28 fits into 88 3 times, leaving a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 143.0
The remainder is 4 after subtracting 84 from 88.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 28

On to step 5:
The number 28 fits into 49 1 times, leaving a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 1431.0
Deduct 28 from 49 and we're left with 21.
Append the next digit (3) from the dividend to 21 and continue with: 213 / 28

Moving on to step 6:
28 can be fit into 213 7 times, resulting in a remainder of 17.
The next digit of our result is 7. 
Result so far: 14317.0
If we subtract 196 from 213, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
28 goes into 170 6 times with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 14317.6
If we subtract 168 from 170, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
When dividing 20 by 28, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 14317.6
If we subtract 0 from 20, we 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.

Moving on to step 9:
28 can be fit into 200 7 times, resulting in a remainder of 4.
The next digit of our result is 7. 
Result so far: 14317.607
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.

Advancing to step 10:
When dividing 40 by 28, we get 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 14317.6071
If we subtract 28 from 40, we 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.

Moving on to step 11:
If we divide 120 by 28, we get 4 and a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 14317.60714
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.

On to step 12:
When dividing 80 by 28, we get 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 14317.607142
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.

Advancing to step 13:
The number 28 fits into 240 8 times, leaving a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 14317.6071428
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:
28 can be fit into 160 5 times, resulting in a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 14317.60714285
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 14317.60714285, with a leftover of 2e-08.
