We look at the division of 521793 by 28 
We want to figure out the number of times 521793 can be divided by 28.

On to step 1:
28 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 28

Step 2:
When dividing 52 by 28, we get 1 with a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 28 from 52, we get 24.
Take the next digit (1) from the dividend and append it to 24, then repeat: 241 / 28

Moving on to step 3:
When dividing 241 by 28, we get 8 with a remainder of 17.
The next digit of our result is 8. 
Result so far: 18.0
The remainder is 17 after subtracting 224 from 241.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 28

On to step 4:
28 goes into 177 6 times with a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 186.0
If we take 168 away from 177, we end up with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 28

Let's proceed to step 5:
28 goes into 99 3 times with a remainder of 15.
The next digit of our result is 3. 
Result so far: 1863.0
Subtracting 84 from 99 leaves us with 15.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 28

Moving on to step 6:
28 can be fit into 153 5 times, resulting in a remainder of 13.
Write down 5 as next digit of the result. 
Result so far: 18635.0
The remainder is 13 after subtracting 140 from 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
When dividing 130 by 28, we get 4 with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 18635.4
The remainder is 18 after subtracting 112 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
180 divided by 28 is 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 18635.46
Deduct 168 from 180 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.

Advancing to step 9:
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: 18635.464
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.

Going ahead to step 10:
If we divide 80 by 28, we get 2 and a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 18635.4642
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.

Moving on to step 11:
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: 18635.46428
The remainder is 16 after subtracting 224 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 12:
160 divided by 28 is 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 18635.464285
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 13:
The number 28 fits into 200 7 times, leaving a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 18635.4642857
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 14:
The number 28 fits into 40 1 times, leaving a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 18635.46428571
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.

In conclusion, the division gives 18635.46428571 with a balance of 1.2e-08.
