We're dividing 747259 by 42 
We're looking to find how many times 42 goes into 747259.

Moving on to step 1:
42 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 42

Going ahead to step 2:
When dividing 74 by 42, we get 1 with a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 42 from 74 and we're left with 32.
Bring next digit (7) of the dividend behind the 32 and repeat the process: 327 / 42

On to step 3:
42 goes into 327 7 times with a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we take 294 away from 327, we end up with 33.
Include the next digit (2) from the dividend after 33, then repeat: 332 / 42

Advancing to step 4:
332 divided by 42 is 7 with a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 177.0
Subtracting 294 from 332 leaves us with 38.
Append the next digit (5) from the dividend to 38 and continue with: 385 / 42

Step 5:
42 can be fit into 385 9 times, resulting in a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 1779.0
Deduct 378 from 385 and we're left with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 42

Moving on to step 6:
The number 42 fits into 79 1 times, leaving a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 17791.0
Subtracting 42 from 79 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 7:
If we divide 370 by 42, we get 8 and a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 17791.8
If we take 336 away from 370, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 8:
340 divided by 42 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 17791.88
Subtract 336 from 340 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.

Our division results in 17791.88 with a remaining 0.004.
