327990 ÷ 45 
We want to figure out the number of times 327990 can be divided by 45.

Moving on to step 1:
When dividing 3 by 45, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 45

Going ahead to step 2:
When dividing 32 by 45, we get 0 with a remainder of 32.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 32 after subtracting 0 from 32.
Take the next digit (7) from the dividend and append it to 32, then repeat: 327 / 45

On to step 3:
If we divide 327 by 45, we get 7 and a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 315 from 327 leaves us with 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 45

Step 4:
45 goes into 129 2 times with a remainder of 39.
Write down 2 as next digit of the result. 
Result so far: 72.0
Deduct 90 from 129 and we're left with 39.
Append the next digit (9) from the dividend to 39 and continue with: 399 / 45

Advancing to step 5:
399 divided by 45 is 8 with a remainder of 39.
The number 8 becomes the next digit in our result. 
Result so far: 728.0
The remainder is 39 after subtracting 360 from 399.
Grab the next digit (0) from the dividend, add it to 39, then carry on: 390 / 45

Moving on to step 6:
390 divided by 45 is 8 with a remainder of 30.
Record the quotient 8 as the next digit in the result. 
Result so far: 7288.0
The remainder is 30 after subtracting 360 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 7:
When dividing 300 by 45, we get 6 with a remainder of 30.
The next digit of our result is 6. 
Result so far: 7288.6
If we subtract 270 from 300, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
The number 45 fits into 300 6 times, leaving a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 7288.66
Deduct 270 from 300 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 7288.66, with a leftover of 0.03.
