77551065 ÷ 120 
Our goal is to divide 77551065 by 120.

Let's proceed to step 1:
120 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 120

On to step 2:
The number 120 fits into 77 0 times, leaving a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Grab the next digit (5) from the dividend, add it to 77, then carry on: 775 / 120

Going ahead to step 3:
120 goes into 775 6 times with a remainder of 55.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 720 from 775 to get 55.
Append the next digit (5) from the dividend to 55 and continue with: 555 / 120

Advancing to step 4:
555 divided by 120 is 4 with a remainder of 75.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
If we subtract 480 from 555, we get 75.
Grab the next digit (1) from the dividend, add it to 75, then carry on: 751 / 120

Moving on to step 5:
120 can be fit into 751 6 times, resulting in a remainder of 31.
The next digit of our result is 6. 
Result so far: 646.0
If we take 720 away from 751, we end up with 31.
Bring next digit (0) of the dividend behind the 31 and repeat the process: 310 / 120

Going ahead to step 6:
120 can be fit into 310 2 times, resulting in a remainder of 70.
Use 2 as the next digit of our solution. 
Result so far: 6462.0
The remainder is 70 after subtracting 240 from 310.
Fetch the next digit (6) from the dividend, attach it to 70 and continue: 706 / 120

Going ahead to step 7:
706 divided by 120 is 5 with a remainder of 106.
The number 5 becomes the next digit in our result. 
Result so far: 64625.0
If we take 600 away from 706, we end up with 106.
Append the next digit (5) from the dividend to 106 and continue with: 1065 / 120

Moving on to step 8:
If we divide 1065 by 120, we get 8 and a remainder of 105.
Put 8 as the next digit of the answer. 
Result so far: 646258.0
Subtract 960 from 1065 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Let's proceed to step 9:
If we divide 1050 by 120, we get 8 and a remainder of 90.
Write down 8 as next digit of the result. 
Result so far: 646258.8
If we take 960 away from 1050, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 10:
The number 120 fits into 900 7 times, leaving a remainder of 60.
The next digit of our result is 7. 
Result so far: 646258.87
If we subtract 840 from 900, 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.

Step 11:
If we divide 600 by 120, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 646258.875
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.

Let's proceed to step 12:
0 divided by 120 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 646258.875
Subtracting 0 from 0 leaves us 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.

Let's proceed to step 13:
When dividing 0 by 120, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 646258.875
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.

Our division results in 646258.875 with a remaining 0.0.
