78799612 ÷ 120 
We're looking to find how many times 120 goes into 78799612.

Going ahead to step 1:
The number 120 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 120

Going ahead to step 2:
When dividing 78 by 120, we get 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Append the next digit (7) from the dividend to 78 and continue with: 787 / 120

Moving on to step 3:
The number 120 fits into 787 6 times, leaving a remainder of 67.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 720 from 787 to get 67.
Append the next digit (9) from the dividend to 67 and continue with: 679 / 120

Step 4:
120 goes into 679 5 times with a remainder of 79.
Put 5 as the next digit of the answer. 
Result so far: 65.0
The remainder is 79 after subtracting 600 from 679.
Grab the next digit (9) from the dividend, add it to 79, then carry on: 799 / 120

Moving on to step 5:
120 goes into 799 6 times with a remainder of 79.
The number 6 becomes the next digit in our result. 
Result so far: 656.0
The remainder is 79 after subtracting 720 from 799.
Append the next digit (6) from the dividend to 79 and continue with: 796 / 120

Advancing to step 6:
The number 120 fits into 796 6 times, leaving a remainder of 76.
Put 6 as the next digit of the answer. 
Result so far: 6566.0
Deduct 720 from 796 and we're left with 76.
Bring next digit (1) of the dividend behind the 76 and repeat the process: 761 / 120

Moving on to step 7:
761 divided by 120 is 6 with a remainder of 41.
Put 6 as the next digit of the answer. 
Result so far: 65666.0
If we subtract 720 from 761, we get 41.
Include the next digit (2) from the dividend after 41, then repeat: 412 / 120

Going ahead to step 8:
120 can be fit into 412 3 times, resulting in a remainder of 52.
Use 3 as the next digit of our solution. 
Result so far: 656663.0
Subtract 360 from 412 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 9:
120 can be fit into 520 4 times, resulting in a remainder of 40.
The next digit of our result is 4. 
Result so far: 656663.4
The remainder is 40 after subtracting 480 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
The number 120 fits into 400 3 times, leaving a remainder of 40.
Use 3 as the next digit of our solution. 
Result so far: 656663.43
Deduct 360 from 400 and we're left 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.

Moving on to step 11:
If we divide 400 by 120, we get 3 and a remainder of 40.
Write down 3 as next digit of the result. 
Result so far: 656663.433
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 656663.433 with a remaining 0.004.
