717449 divided by 42 
We want to figure out the number of times 717449 can be divided by 42.

Let's proceed to step 1:
The number 42 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 42

On to step 2:
When dividing 71 by 42, we get 1 with a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 42 from 71 to get 29.
Grab the next digit (7) from the dividend, add it to 29, then carry on: 297 / 42

On to step 3:
42 goes into 297 7 times with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 17.0
The remainder is 3 after subtracting 294 from 297.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 42

Let's proceed to step 4:
34 divided by 42 is 0 with a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 170.0
If we subtract 0 from 34, we get 34.
Include the next digit (4) from the dividend after 34, then repeat: 344 / 42

Advancing to step 5:
344 divided by 42 is 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 1708.0
If we subtract 336 from 344, we get 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 42

Let's proceed to step 6:
If we divide 89 by 42, we get 2 and a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 17082.0
Subtracting 84 from 89 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
The number 42 fits into 50 1 times, leaving a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 17082.1
Deduct 42 from 50 and we're left 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.

Step 8:
80 divided by 42 is 1 with a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 17082.11
Subtracting 42 from 80 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

After the division, we end up with 17082.11 and a remainder of 0.038.
