We divide 421424 by 28
Our goal is to divide 421424 by 28.

Moving on to step 1:
If we divide 4 by 28, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 28

Going ahead to step 2:
28 can be fit into 42 1 times, resulting in a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 28 from 42 and we're left with 14.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 28

Advancing to step 3:
28 can be fit into 141 5 times, resulting in a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Deduct 140 from 141 and we're left with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 28

Moving on to step 4:
28 goes into 14 0 times with a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 150.0
Deduct 0 from 14 and we're left with 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 28

On to step 5:
142 divided by 28 is 5 with a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 1505.0
Subtract 140 from 142 to get 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 28

Going ahead to step 6:
28 goes into 24 0 times with a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 15050.0
Subtract 0 from 24 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.

Advancing to step 7:
240 divided by 28 is 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 15050.8
Deduct 224 from 240 and we're left 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.

Going ahead to step 8:
160 divided by 28 is 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 15050.85
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 9:
28 goes into 200 7 times with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 15050.857
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.

Going ahead to step 10:
When dividing 40 by 28, we get 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 15050.8571
Subtracting 28 from 40 leaves us 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 11:
28 can be fit into 120 4 times, resulting in a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 15050.85714
The remainder is 8 after subtracting 112 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 12:
When dividing 80 by 28, we get 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 15050.857142
Subtracting 56 from 80 leaves us 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.

On to step 13:
28 goes into 240 8 times with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 15050.8571428
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.

On to step 14:
160 divided by 28 is 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 15050.85714285
If we take 140 away from 160, we end up 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.

After the division, we end up with 15050.85714285 and a remainder of 2e-08.
