We look at the division of 117980 by 45 
We want to divide 117980 by 45.

Step 1:
45 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 45

Moving on to step 2:
If we divide 11 by 45, we get 0 and a remainder of 11.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 11 and we're left with 11.
Bring next digit (7) of the dividend behind the 11 and repeat the process: 117 / 45

Advancing to step 3:
If we divide 117 by 45, we get 2 and a remainder of 27.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 27 after subtracting 90 from 117.
Grab the next digit (9) from the dividend, add it to 27, then carry on: 279 / 45

Moving on to step 4:
The number 45 fits into 279 6 times, leaving a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
Subtract 270 from 279 to get 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 45

Going ahead to step 5:
98 divided by 45 is 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 262.0
Subtracting 90 from 98 leaves us with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 45

Step 6:
When dividing 80 by 45, we get 1 with a remainder of 35.
The next digit of our result is 1. 
Result so far: 2621.0
If we subtract 45 from 80, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 7:
If we divide 350 by 45, we get 7 and a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 2621.7
Subtracting 315 from 350 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 8:
When dividing 350 by 45, we get 7 with a remainder of 35.
The next digit of our result is 7. 
Result so far: 2621.77
Subtracting 315 from 350 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final outcome is 2621.77, with a leftover of 0.035.
