We look at the division of 827921 by 45 
We want to figure out the number of times 827921 can be divided by 45.

Going ahead to step 1:
If we divide 8 by 45, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 45

Step 2:
45 goes into 82 1 times with a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 45 from 82 leaves us with 37.
Append the next digit (7) from the dividend to 37 and continue with: 377 / 45

Step 3:
45 goes into 377 8 times with a remainder of 17.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Deduct 360 from 377 and we're left with 17.
Fetch the next digit (9) from the dividend, attach it to 17 and continue: 179 / 45

Moving on to step 4:
45 goes into 179 3 times with a remainder of 44.
Use 3 as the next digit of our solution. 
Result so far: 183.0
If we subtract 135 from 179, we get 44.
Fetch the next digit (2) from the dividend, attach it to 44 and continue: 442 / 45

On to step 5:
442 divided by 45 is 9 with a remainder of 37.
The number 9 becomes the next digit in our result. 
Result so far: 1839.0
Subtract 405 from 442 to get 37.
Append the next digit (1) from the dividend to 37 and continue with: 371 / 45

Advancing to step 6:
45 goes into 371 8 times with a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 18398.0
If we subtract 360 from 371, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
The number 45 fits into 110 2 times, leaving a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 18398.2
Subtracting 90 from 110 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
200 divided by 45 is 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 18398.24
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
The number 45 fits into 200 4 times, leaving a remainder of 20.
The next digit of our result is 4. 
Result so far: 18398.244
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 18398.244 with a remaining 0.002.
