We're dividing 909126 by 45 
We're looking to find how many times 45 goes into 909126.

On to step 1:
9 divided by 45 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 45

On to step 2:
The number 45 fits into 90 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 90 from 90 to get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 45

On to step 3:
45 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we subtract 0 from 9, we get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 45

Going ahead to step 4:
45 can be fit into 91 2 times, resulting in a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 202.0
Subtract 90 from 91 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 45

Let's proceed to step 5:
45 goes into 12 0 times with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 2020.0
Subtract 0 from 12 to get 12.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 45

Advancing to step 6:
If we divide 126 by 45, we get 2 and a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 20202.0
If we take 90 away from 126, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 7:
45 goes into 360 8 times with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 20202.8
The remainder is 0 after subtracting 360 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
0 divided by 45 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 20202.8
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
45 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 20202.8
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 20202.8, with a leftover of 0.0.
