We're dividing 745099 by 78 
We want to divide 745099 by 78.

On to step 1:
If we divide 7 by 78, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 78

On to step 2:
74 divided by 78 is 0 with a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Take the next digit (5) from the dividend and append it to 74, then repeat: 745 / 78

Going ahead to step 3:
78 can be fit into 745 9 times, resulting in a remainder of 43.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 702 from 745 leaves us with 43.
Grab the next digit (0) from the dividend, add it to 43, then carry on: 430 / 78

On to step 4:
78 goes into 430 5 times with a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 95.0
Deduct 390 from 430 and we're left with 40.
Grab the next digit (9) from the dividend, add it to 40, then carry on: 409 / 78

Going ahead to step 5:
When dividing 409 by 78, we get 5 with a remainder of 19.
Use 5 as the next digit of our solution. 
Result so far: 955.0
Deduct 390 from 409 and we're left with 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 78

Moving on to step 6:
When dividing 199 by 78, we get 2 with a remainder of 43.
The number 2 becomes the next digit in our result. 
Result so far: 9552.0
Subtracting 156 from 199 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 7:
The number 78 fits into 430 5 times, leaving a remainder of 40.
The next digit of our result is 5. 
Result so far: 9552.5
Subtracting 390 from 430 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
The number 78 fits into 400 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 9552.55
If we take 390 away from 400, we end up 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.

The quotient of the division is 9552.55, and the remainder is 0.01.
