We look at the division of 91225723 by 45 
Our goal is to divide 91225723 by 45.

Going ahead to step 1:
The number 45 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 45

Going ahead to step 2:
45 can be fit into 91 2 times, resulting in a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 90 from 91, we get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 45

Let's proceed to step 3:
When dividing 12 by 45, we get 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtract 0 from 12 to get 12.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 45

Step 4:
If we divide 122 by 45, we get 2 and a remainder of 32.
The next digit of our result is 2. 
Result so far: 202.0
If we take 90 away from 122, we end up with 32.
Grab the next digit (5) from the dividend, add it to 32, then carry on: 325 / 45

Step 5:
If we divide 325 by 45, we get 7 and a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 2027.0
The remainder is 10 after subtracting 315 from 325.
Bring next digit (7) of the dividend behind the 10 and repeat the process: 107 / 45

Advancing to step 6:
45 can be fit into 107 2 times, resulting in a remainder of 17.
The number 2 becomes the next digit in our result. 
Result so far: 20272.0
Subtract 90 from 107 to get 17.
Bring next digit (2) of the dividend behind the 17 and repeat the process: 172 / 45

Let's proceed to step 7:
When dividing 172 by 45, we get 3 with a remainder of 37.
The next digit of our result is 3. 
Result so far: 202723.0
The remainder is 37 after subtracting 135 from 172.
Include the next digit (3) from the dividend after 37, then repeat: 373 / 45

On to step 8:
45 can be fit into 373 8 times, resulting in a remainder of 13.
Use 8 as the next digit of our solution. 
Result so far: 2027238.0
The remainder is 13 after subtracting 360 from 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 9:
The number 45 fits into 130 2 times, leaving a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 2027238.2
Subtracting 90 from 130 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
400 divided by 45 is 8 with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 2027238.28
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
If we divide 400 by 45, we get 8 and a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 2027238.288
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 2027238.288 with a remaining 0.004.
