We look at the division of 28729 by 4 
We want to divide 28729 by 4.

Step 1:
The number 4 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 4

Going ahead to step 2:
The number 4 fits into 28 7 times, leaving a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 28 from 28 to get 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 4

Step 3:
4 goes into 7 1 times with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 71.0
If we subtract 4 from 7, we get 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 4

Going ahead to step 4:
4 can be fit into 32 8 times, resulting in a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 718.0
If we take 32 away from 32, we end up with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 4

On to step 5:
The number 4 fits into 9 2 times, leaving a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 7182.0
If we take 8 away from 9, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 6:
When dividing 10 by 4, we get 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 7182.2
If we subtract 8 from 10, 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.

Going ahead to step 7:
The number 4 fits into 20 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 7182.25
Subtract 20 from 20 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
When dividing 0 by 4, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 7182.25
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
0 divided by 4 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7182.25
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 7182.25, with a leftover of 0.0.
