We're dividing 748579 by 42 
We're looking to find how many times 42 goes into 748579.

On to step 1:
When dividing 7 by 42, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 42

Step 2:
If we divide 74 by 42, we get 1 and a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 32 after subtracting 42 from 74.
Take the next digit (8) from the dividend and append it to 32, then repeat: 328 / 42

Let's proceed to step 3:
42 can be fit into 328 7 times, resulting in a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Deduct 294 from 328 and we're left with 34.
Take the next digit (5) from the dividend and append it to 34, then repeat: 345 / 42

Let's proceed to step 4:
42 goes into 345 8 times with a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 178.0
Subtract 336 from 345 to get 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 42

Going ahead to step 5:
42 can be fit into 97 2 times, resulting in a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 1782.0
If we subtract 84 from 97, we get 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 42

On to step 6:
42 can be fit into 139 3 times, resulting in a remainder of 13.
The next digit of our result is 3. 
Result so far: 17823.0
If we take 126 away from 139, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
42 goes into 130 3 times with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 17823.3
Deduct 126 from 130 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.

Let's proceed to step 8:
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: 17823.3
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
400 divided by 42 is 9 with a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 17823.309
Deduct 378 from 400 and we're left 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.

Step 10:
42 can be fit into 220 5 times, resulting in a remainder of 10.
The next digit of our result is 5. 
Result so far: 17823.3095
If we subtract 210 from 220, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 11:
The number 42 fits into 100 2 times, leaving a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 17823.30952
Subtracting 84 from 100 leaves us 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.

Moving on to step 12:
42 goes into 160 3 times with a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 17823.309523
If we subtract 126 from 160, we 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.

Advancing to step 13:
340 divided by 42 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 17823.3095238
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.

Step 14:
40 divided by 42 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 17823.3095238
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 17823.3095238 with a balance of 4e-08.
