We're dividing 991648 by 89 
We're looking to find how many times 89 goes into 991648.

Let's proceed to step 1:
When dividing 9 by 89, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 89

Step 2:
When dividing 99 by 89, we get 1 with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 89 from 99 to get 10.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 89

Going ahead to step 3:
89 can be fit into 101 1 times, resulting in a remainder of 12.
The next digit of our result is 1. 
Result so far: 11.0
Deduct 89 from 101 and we're left with 12.
Bring next digit (6) of the dividend behind the 12 and repeat the process: 126 / 89

Going ahead to step 4:
89 goes into 126 1 times with a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 111.0
Subtracting 89 from 126 leaves us with 37.
Append the next digit (4) from the dividend to 37 and continue with: 374 / 89

Moving on to step 5:
374 divided by 89 is 4 with a remainder of 18.
The next digit of our result is 4. 
Result so far: 1114.0
Deduct 356 from 374 and we're left with 18.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 89

Going ahead to step 6:
188 divided by 89 is 2 with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 11142.0
If we subtract 178 from 188, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
89 can be fit into 100 1 times, resulting in a remainder of 11.
The next digit of our result is 1. 
Result so far: 11142.1
Subtract 89 from 100 to 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.

Step 8:
If we divide 110 by 89, we get 1 and a remainder of 21.
The next digit of our result is 1. 
Result so far: 11142.11
If we subtract 89 from 110, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

After the division, we end up with 11142.11 and a remainder of 0.021.
