We're dividing 42491362 by 918 
We want to figure out the number of times 42491362 can be divided by 918.

On to step 1:
918 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 918

On to step 2:
42 divided by 918 is 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Include the next digit (4) from the dividend after 42, then repeat: 424 / 918

Step 3:
When dividing 424 by 918, we get 0 with a remainder of 424.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 424 leaves us with 424.
Append the next digit (9) from the dividend to 424 and continue with: 4249 / 918

Going ahead to step 4:
918 goes into 4249 4 times with a remainder of 577.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 3672 from 4249 leaves us with 577.
Fetch the next digit (1) from the dividend, attach it to 577 and continue: 5771 / 918

Going ahead to step 5:
The number 918 fits into 5771 6 times, leaving a remainder of 263.
Write down 6 as next digit of the result. 
Result so far: 46.0
Subtract 5508 from 5771 to get 263.
Append the next digit (3) from the dividend to 263 and continue with: 2633 / 918

Step 6:
When dividing 2633 by 918, we get 2 with a remainder of 797.
Write down 2 as next digit of the result. 
Result so far: 462.0
If we take 1836 away from 2633, we end up with 797.
Append the next digit (6) from the dividend to 797 and continue with: 7976 / 918

Going ahead to step 7:
7976 divided by 918 is 8 with a remainder of 632.
The number 8 becomes the next digit in our result. 
Result so far: 4628.0
If we subtract 7344 from 7976, we get 632.
Grab the next digit (2) from the dividend, add it to 632, then carry on: 6322 / 918

Moving on to step 8:
918 goes into 6322 6 times with a remainder of 814.
The next digit of our result is 6. 
Result so far: 46286.0
If we take 5508 away from 6322, we end up with 814.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8140, and continue the process.

Advancing to step 9:
918 goes into 8140 8 times with a remainder of 796.
Record the quotient 8 as the next digit in the result. 
Result so far: 46286.8
If we take 7344 away from 8140, we end up with 796.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7960, and continue the process.

On to step 10:
When dividing 7960 by 918, we get 8 with a remainder of 616.
Record the quotient 8 as the next digit in the result. 
Result so far: 46286.88
Deduct 7344 from 7960 and we're left with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

The final result is 46286.88 with a remainder of 0.616.
