We look at the division of 458728 by 42 
We want to figure out the number of times 458728 can be divided by 42.

On to step 1:
When dividing 4 by 42, we get 0 with 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.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 42

Step 2:
If we divide 45 by 42, we get 1 and a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 42 from 45 leaves us with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 42

Advancing to step 3:
The number 42 fits into 38 0 times, leaving a remainder of 38.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 38 after subtracting 0 from 38.
Include the next digit (7) from the dividend after 38, then repeat: 387 / 42

Step 4:
The number 42 fits into 387 9 times, leaving a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 109.0
If we subtract 378 from 387, we get 9.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 42

Moving on to step 5:
If we divide 92 by 42, we get 2 and a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 1092.0
Deduct 84 from 92 and we're left with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 42

Moving on to step 6:
42 goes into 88 2 times with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 10922.0
Subtract 84 from 88 to 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 7:
When dividing 40 by 42, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 10922.0
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 8:
42 can be fit into 400 9 times, resulting in a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 10922.09
Subtract 378 from 400 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 9:
42 goes into 220 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 10922.095
The remainder is 10 after subtracting 210 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
The number 42 fits into 100 2 times, leaving a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 10922.0952
Subtract 84 from 100 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 11:
When dividing 160 by 42, we get 3 with a remainder of 34.
The next digit of our result is 3. 
Result so far: 10922.09523
Subtract 126 from 160 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 12:
If we divide 340 by 42, we get 8 and a remainder of 4.
The next digit of our result is 8. 
Result so far: 10922.095238
If we subtract 336 from 340, 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.

Advancing to step 13:
42 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 10922.095238
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 14:
42 goes into 400 9 times with a remainder of 22.
The next digit of our result is 9. 
Result so far: 10922.09523809
If we take 378 away from 400, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The quotient of the division is 10922.09523809, and the remainder is 2.2e-08.
