We're dividing 420275 by 28 
Let's see how many times 28 fits into 420275.

Going ahead to step 1:
4 divided by 28 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 28

Advancing to step 2:
When dividing 42 by 28, we get 1 with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 14 after subtracting 28 from 42.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 28

Going ahead to step 3:
The number 28 fits into 140 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 140 from 140 leaves us with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 28

Let's proceed to step 4:
2 divided by 28 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 150.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 28

Moving on to step 5:
28 can be fit into 27 0 times, resulting in a remainder of 27.
Put 0 as the next digit of the answer. 
Result so far: 1500.0
Subtract 0 from 27 to get 27.
Append the next digit (5) from the dividend to 27 and continue with: 275 / 28

On to step 6:
When dividing 275 by 28, we get 9 with a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 15009.0
If we subtract 252 from 275, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 7:
If we divide 230 by 28, we get 8 and a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 15009.8
Deduct 224 from 230 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
The number 28 fits into 60 2 times, leaving a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 15009.82
Subtracting 56 from 60 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 9:
When dividing 40 by 28, we get 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 15009.821
Deduct 28 from 40 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.

Going ahead to step 10:
The number 28 fits into 120 4 times, leaving a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 15009.8214
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.

Step 11:
If we divide 80 by 28, we get 2 and a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 15009.82142
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:
28 goes into 240 8 times with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 15009.821428
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.

Advancing to step 13:
If we divide 160 by 28, we get 5 and a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 15009.8214285
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.

Advancing to step 14:
When dividing 200 by 28, we get 7 with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 15009.82142857
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.

After the division, we end up with 15009.82142857 and a remainder of 4e-09.
