912536 ÷ 45 
We want to figure out the number of times 912536 can be divided by 45.

Step 1:
If we divide 9 by 45, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 45

Advancing 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 take 90 away from 91, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 45

Let's proceed to step 3:
If we divide 12 by 45, we get 0 and a remainder of 12.
The next digit of our result is 0. 
Result so far: 20.0
The remainder is 12 after subtracting 0 from 12.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 45

Advancing to step 4:
If we divide 125 by 45, we get 2 and a remainder of 35.
The next digit of our result is 2. 
Result so far: 202.0
Subtract 90 from 125 to get 35.
Grab the next digit (3) from the dividend, add it to 35, then carry on: 353 / 45

Step 5:
353 divided by 45 is 7 with a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 2027.0
The remainder is 38 after subtracting 315 from 353.
Grab the next digit (6) from the dividend, add it to 38, then carry on: 386 / 45

Advancing to step 6:
When dividing 386 by 45, we get 8 with a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 20278.0
If we subtract 360 from 386, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 7:
260 divided by 45 is 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 20278.5
Deduct 225 from 260 and we're left 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.

Going ahead to step 8:
When dividing 350 by 45, we get 7 with a remainder of 35.
The next digit of our result is 7. 
Result so far: 20278.57
If we take 315 away from 350, 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.

Step 9:
45 goes into 350 7 times with a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 20278.577
If we subtract 315 from 350, we get 35.
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 20278.577 and a remainder of 0.0035.
