We're dividing 708940 by 45 
Our goal is to divide 708940 by 45.

On 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
If we subtract 0 from 7, we get 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 45

On to step 2:
45 can be fit into 70 1 times, resulting in a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 25 after subtracting 45 from 70.
Fetch the next digit (8) from the dividend, attach it to 25 and continue: 258 / 45

On to step 3:
45 can be fit into 258 5 times, resulting in a remainder of 33.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtract 225 from 258 to get 33.
Include the next digit (9) from the dividend after 33, then repeat: 339 / 45

Going ahead to step 4:
339 divided by 45 is 7 with a remainder of 24.
Write down 7 as next digit of the result. 
Result so far: 157.0
The remainder is 24 after subtracting 315 from 339.
Grab the next digit (4) from the dividend, add it to 24, then carry on: 244 / 45

On to step 5:
When dividing 244 by 45, we get 5 with a remainder of 19.
Put 5 as the next digit of the answer. 
Result so far: 1575.0
Subtracting 225 from 244 leaves us with 19.
Include the next digit (0) from the dividend after 19, then repeat: 190 / 45

Going ahead to step 6:
45 goes into 190 4 times with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 15754.0
Subtract 180 from 190 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
45 goes into 100 2 times with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 15754.2
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
45 can be fit into 100 2 times, resulting in a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 15754.22
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 15754.22 with a remaining 0.01.
