915934 ÷ 45 
We want to figure out the number of times 915934 can be divided by 45.

On to step 1:
9 divided by 45 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 45

Going ahead to step 2:
When dividing 91 by 45, we get 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 90 from 91, we get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 45

On to step 3:
15 divided by 45 is 0 with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtracting 0 from 15 leaves us with 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 45

Step 4:
159 divided by 45 is 3 with a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 203.0
If we take 135 away from 159, we end up with 24.
Grab the next digit (3) from the dividend, add it to 24, then carry on: 243 / 45

Moving on to step 5:
45 goes into 243 5 times with a remainder of 18.
Record the quotient 5 as the next digit in the result. 
Result so far: 2035.0
If we take 225 away from 243, we end up with 18.
Take the next digit (4) from the dividend and append it to 18, then repeat: 184 / 45

Moving on to step 6:
The number 45 fits into 184 4 times, leaving a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 20354.0
Subtract 180 from 184 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
40 divided by 45 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 20354.0
If we take 0 away from 40, we end up 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.

Moving on to step 8:
When dividing 400 by 45, we get 8 with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 20354.08
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.

Moving on to step 9:
400 divided by 45 is 8 with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 20354.088
Subtracting 360 from 400 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.

The final outcome is 20354.088, with a leftover of 0.004.
