420740 ÷ 28 
Let's see how many times 28 fits into 420740.

Step 1:
28 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 28

Going ahead to step 2:
The number 28 fits into 42 1 times, leaving a remainder of 14.
Write down 1 as next digit of the result. 
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

Advancing to step 3:
28 can be fit into 140 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 140 from 140 and we're left with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 28

Let's proceed to step 4:
When dividing 7 by 28, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 150.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 28

Advancing to step 5:
If we divide 74 by 28, we get 2 and a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 1502.0
Subtracting 56 from 74 leaves us with 18.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 28

On to step 6:
If we divide 180 by 28, we get 6 and a remainder of 12.
The next digit of our result is 6. 
Result so far: 15026.0
Subtract 168 from 180 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.

Going ahead to step 7:
When dividing 120 by 28, we get 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 15026.4
Subtract 112 from 120 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
The number 28 fits into 80 2 times, leaving a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 15026.42
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.

Advancing to step 9:
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: 15026.428
Subtract 224 from 240 to 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.

Let's proceed to step 10:
When dividing 160 by 28, we get 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 15026.4285
If we subtract 140 from 160, we get 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 11:
200 divided by 28 is 7 with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 15026.42857
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.

On to step 12:
When dividing 40 by 28, we get 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 15026.428571
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.

Let's proceed to step 13:
If we divide 120 by 28, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 15026.4285714
Subtracting 112 from 120 leaves us 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.

On to step 14:
28 can be fit into 80 2 times, resulting in a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 15026.42857142
The remainder is 24 after subtracting 56 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

In conclusion, the division gives 15026.42857142 with a balance of 2.4e-08.
