868730 ÷ 45 
We want to figure out the number of times 868730 can be divided by 45.

Going ahead to step 1:
The number 45 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 45

Let's proceed to step 2:
The number 45 fits into 86 1 times, leaving a remainder of 41.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 41 after subtracting 45 from 86.
Fetch the next digit (8) from the dividend, attach it to 41 and continue: 418 / 45

On to step 3:
418 divided by 45 is 9 with a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtracting 405 from 418 leaves us with 13.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 45

On to step 4:
The number 45 fits into 137 3 times, leaving a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 193.0
Subtracting 135 from 137 leaves us with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 45

Let's proceed to step 5:
23 divided by 45 is 0 with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 1930.0
If we subtract 0 from 23, we get 23.
Fetch the next digit (0) from the dividend, attach it to 23 and continue: 230 / 45

On to step 6:
The number 45 fits into 230 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 19305.0
Deduct 225 from 230 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
When dividing 50 by 45, we get 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 19305.1
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
50 divided by 45 is 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 19305.11
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 19305.11, with a leftover of 0.005.
