726915 ÷ 42 
Let's see how many times 42 fits into 726915.

Let's proceed to step 1:
7 divided by 42 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 42

On to step 2:
The number 42 fits into 72 1 times, leaving a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 30 after subtracting 42 from 72.
Fetch the next digit (6) from the dividend, attach it to 30 and continue: 306 / 42

On to step 3:
306 divided by 42 is 7 with a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtracting 294 from 306 leaves us with 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 42

Going ahead to step 4:
The number 42 fits into 129 3 times, leaving a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 173.0
Subtracting 126 from 129 leaves us with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 42

Advancing to step 5:
When dividing 31 by 42, we get 0 with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 1730.0
If we take 0 away from 31, we end up with 31.
Bring next digit (5) of the dividend behind the 31 and repeat the process: 315 / 42

Going ahead to step 6:
When dividing 315 by 42, we get 7 with a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 17307.0
If we take 294 away from 315, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 7:
210 divided by 42 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 17307.5
If we subtract 210 from 210, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
The number 42 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 17307.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
0 divided by 42 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 17307.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 17307.5 and a remainder of 0.0.
