Let's divide 420772 by 28
We want to figure out the number of times 420772 can be divided by 28.

Step 1:
28 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 28

Let's proceed to step 2:
When dividing 42 by 28, we get 1 with a remainder of 14.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 28 from 42, we get 14.
Include the next digit (0) from the dividend after 14, then repeat: 140 / 28

Step 3:
The number 28 fits into 140 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 15.0
The remainder is 0 after subtracting 140 from 140.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 28

On to step 4:
7 divided by 28 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 150.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 28

On to step 5:
The number 28 fits into 77 2 times, leaving a remainder of 21.
The number 2 becomes the next digit in our result. 
Result so far: 1502.0
If we take 56 away from 77, we end up with 21.
Take the next digit (2) from the dividend and append it to 21, then repeat: 212 / 28

Step 6:
28 can be fit into 212 7 times, resulting in a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 15027.0
If we subtract 196 from 212, 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.

Advancing to step 7:
28 can be fit into 160 5 times, resulting in a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 15027.5
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.

Step 8:
28 goes into 200 7 times with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 15027.57
If we subtract 196 from 200, we get 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 9:
40 divided by 28 is 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 15027.571
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.

Step 10:
When dividing 120 by 28, we get 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 15027.5714
If we take 112 away from 120, we end up 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.

Advancing to step 11:
When dividing 80 by 28, we get 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 15027.57142
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.

Going ahead to step 12:
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: 15027.571428
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 13:
160 divided by 28 is 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 15027.5714285
The remainder is 20 after subtracting 140 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 14:
When dividing 200 by 28, we get 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 15027.57142857
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.

Our division results in 15027.57142857 with a remaining 4e-09.
