77917899 divided by 120 
We want to figure out the number of times 77917899 can be divided by 120.

Let's proceed to step 1:
The number 120 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 120

Moving on to step 2:
The number 120 fits into 77 0 times, leaving a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Grab the next digit (9) from the dividend, add it to 77, then carry on: 779 / 120

Let's proceed to step 3:
120 can be fit into 779 6 times, resulting in a remainder of 59.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 720 from 779 and we're left with 59.
Bring next digit (1) of the dividend behind the 59 and repeat the process: 591 / 120

Step 4:
If we divide 591 by 120, we get 4 and a remainder of 111.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
Deduct 480 from 591 and we're left with 111.
Take the next digit (7) from the dividend and append it to 111, then repeat: 1117 / 120

Advancing to step 5:
120 can be fit into 1117 9 times, resulting in a remainder of 37.
Record the quotient 9 as the next digit in the result. 
Result so far: 649.0
Deduct 1080 from 1117 and we're left with 37.
Bring next digit (8) of the dividend behind the 37 and repeat the process: 378 / 120

Going ahead to step 6:
When dividing 378 by 120, we get 3 with a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 6493.0
Subtracting 360 from 378 leaves us with 18.
Fetch the next digit (9) from the dividend, attach it to 18 and continue: 189 / 120

Advancing to step 7:
If we divide 189 by 120, we get 1 and a remainder of 69.
The next digit of our result is 1. 
Result so far: 64931.0
The remainder is 69 after subtracting 120 from 189.
Append the next digit (9) from the dividend to 69 and continue with: 699 / 120

Let's proceed to step 8:
If we divide 699 by 120, we get 5 and a remainder of 99.
The next digit of our result is 5. 
Result so far: 649315.0
The remainder is 99 after subtracting 600 from 699.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Going ahead to step 9:
120 goes into 990 8 times with a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 649315.8
Subtract 960 from 990 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
120 goes into 300 2 times with a remainder of 60.
The next digit of our result is 2. 
Result so far: 649315.82
If we subtract 240 from 300, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 11:
120 can be fit into 600 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 649315.825
If we subtract 600 from 600, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 12:
The number 120 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 649315.825
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 13:
If we divide 0 by 120, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 649315.825
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 649315.825, with a leftover of 0.0.
