729160 ÷ 45 
We want to figure out the number of times 729160 can be divided by 45.

Moving on to step 1:
45 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 45

Advancing to step 2:
If we divide 72 by 45, we get 1 and a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 45 from 72, we get 27.
Fetch the next digit (9) from the dividend, attach it to 27 and continue: 279 / 45

Step 3:
When dividing 279 by 45, we get 6 with a remainder of 9.
The next digit of our result is 6. 
Result so far: 16.0
If we subtract 270 from 279, we get 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 45

Moving on to step 4:
91 divided by 45 is 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 162.0
The remainder is 1 after subtracting 90 from 91.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 45

Going ahead to step 5:
16 divided by 45 is 0 with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 1620.0
Deduct 0 from 16 and we're left with 16.
Fetch the next digit (0) from the dividend, attach it to 16 and continue: 160 / 45

Going ahead to step 6:
The number 45 fits into 160 3 times, leaving a remainder of 25.
The next digit of our result is 3. 
Result so far: 16203.0
Subtract 135 from 160 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 7:
When dividing 250 by 45, we get 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 16203.5
If we take 225 away from 250, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 8:
45 goes into 250 5 times with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 16203.55
The remainder is 25 after subtracting 225 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The quotient of the division is 16203.55, and the remainder is 0.025.
