We're dividing 991494 by 42 
We want to figure out the number of times 991494 can be divided by 42.

Let's proceed to step 1:
When dividing 9 by 42, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 42

Moving on to step 2:
The number 42 fits into 99 2 times, leaving a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 84 from 99 leaves us with 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 42

Going ahead to step 3:
If we divide 151 by 42, we get 3 and a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 23.0
The remainder is 25 after subtracting 126 from 151.
Append the next digit (4) from the dividend to 25 and continue with: 254 / 42

Step 4:
The number 42 fits into 254 6 times, leaving a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 236.0
Subtract 252 from 254 to get 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 42

Advancing to step 5:
42 goes into 29 0 times with a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 2360.0
The remainder is 29 after subtracting 0 from 29.
Bring next digit (4) of the dividend behind the 29 and repeat the process: 294 / 42

Advancing to step 6:
When dividing 294 by 42, we get 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 23607.0
Subtract 294 from 294 to 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.

Step 7:
When dividing 0 by 42, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 23607.0
If we subtract 0 from 0, 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.

Let's proceed to step 8:
The number 42 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 23607.0
Subtract 0 from 0 to 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.

The final outcome is 23607.0, with a leftover of 0.0.
