We look at the division of 9980 by 45 
Our goal is to divide 9980 by 45.

Advancing to step 1:
45 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 45

Let's proceed to step 2:
45 goes into 99 2 times with a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 9 after subtracting 90 from 99.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 45

Going ahead to step 3:
When dividing 98 by 45, we get 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we subtract 90 from 98, we get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 45

Let's proceed to step 4:
When dividing 80 by 45, we get 1 with a remainder of 35.
Record the quotient 1 as the next digit in the result. 
Result so far: 221.0
If we take 45 away from 80, we end up 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.

Let's proceed to step 5:
If we divide 350 by 45, we get 7 and a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 221.7
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.

On to step 6:
45 can be fit into 350 7 times, resulting in a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 221.77
The remainder is 35 after subtracting 315 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

After the division, we end up with 221.77 and a remainder of 0.035.
