We look at the division of 991051 by 45 
We want to divide 991051 by 45.

Let's proceed to step 1:
45 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 45

Going ahead to step 2:
The number 45 fits into 99 2 times, leaving a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 90 from 99 leaves us with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 45

Advancing to step 3:
When dividing 91 by 45, we get 2 with a remainder of 1.
The next digit of our result is 2. 
Result so far: 22.0
If we subtract 90 from 91, we get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 45

Advancing to step 4:
45 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 220.0
Subtracting 0 from 10 leaves us with 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 45

On to step 5:
45 goes into 105 2 times with a remainder of 15.
The next digit of our result is 2. 
Result so far: 2202.0
If we take 90 away from 105, we end up with 15.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 45

Advancing to step 6:
The number 45 fits into 151 3 times, leaving a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 22023.0
Subtract 135 from 151 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
45 goes into 160 3 times with a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 22023.3
The remainder is 25 after subtracting 135 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 8:
250 divided by 45 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 22023.35
Subtracting 225 from 250 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
The number 45 fits into 250 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 22023.355
Subtract 225 from 250 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final result is 22023.355 with a remainder of 0.0025.
