722400 divided by 45 
We want to divide 722400 by 45.

Let's proceed to step 1:
The number 45 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 45

Moving on to step 2:
If we divide 72 by 45, we get 1 and a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 45 from 72 leaves us with 27.
Take the next digit (2) from the dividend and append it to 27, then repeat: 272 / 45

Step 3:
45 can be fit into 272 6 times, resulting in a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we subtract 270 from 272, we get 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 45

Going ahead to step 4:
The number 45 fits into 24 0 times, leaving a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 160.0
If we subtract 0 from 24, we get 24.
Grab the next digit (0) from the dividend, add it to 24, then carry on: 240 / 45

Step 5:
The number 45 fits into 240 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 1605.0
Deduct 225 from 240 and we're left with 15.
Include the next digit (0) from the dividend after 15, then repeat: 150 / 45

Moving on to step 6:
150 divided by 45 is 3 with a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 16053.0
Deduct 135 from 150 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
45 goes into 150 3 times with a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 16053.3
Subtracting 135 from 150 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 8:
When dividing 150 by 45, we get 3 with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 16053.33
If we take 135 away from 150, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 16053.33, with a leftover of 0.015.
