917684 ÷ 45 
We're looking to find how many times 45 goes into 917684.

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.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 45

Advancing to step 2:
The number 45 fits into 91 2 times, leaving a remainder of 1.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 1 after subtracting 90 from 91.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 45

On to step 3:
When dividing 17 by 45, we get 0 with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we subtract 0 from 17, we get 17.
Fetch the next digit (6) from the dividend, attach it to 17 and continue: 176 / 45

Advancing to step 4:
45 can be fit into 176 3 times, resulting in a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 203.0
If we take 135 away from 176, we end up with 41.
Append the next digit (8) from the dividend to 41 and continue with: 418 / 45

Step 5:
When dividing 418 by 45, we get 9 with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 2039.0
Subtracting 405 from 418 leaves us with 13.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 45

Going ahead to step 6:
The number 45 fits into 134 2 times, leaving a remainder of 44.
The next digit of our result is 2. 
Result so far: 20392.0
Subtract 90 from 134 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 7:
45 goes into 440 9 times with a remainder of 35.
Use 9 as the next digit of our solution. 
Result so far: 20392.9
Deduct 405 from 440 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.

On to step 8:
If we divide 350 by 45, we get 7 and a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 20392.97
Deduct 315 from 350 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.

Step 9:
350 divided by 45 is 7 with a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 20392.977
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.

The final outcome is 20392.977, with a leftover of 0.0035.
