Let's divide 81583661 by 120
We're looking to find how many times 120 goes into 81583661.

Step 1:
120 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 120

Going ahead to step 2:
When dividing 81 by 120, we get 0 with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Fetch the next digit (5) from the dividend, attach it to 81 and continue: 815 / 120

Advancing to step 3:
815 divided by 120 is 6 with a remainder of 95.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 720 from 815 to get 95.
Take the next digit (8) from the dividend and append it to 95, then repeat: 958 / 120

Step 4:
120 goes into 958 7 times with a remainder of 118.
The next digit of our result is 7. 
Result so far: 67.0
If we subtract 840 from 958, we get 118.
Append the next digit (3) from the dividend to 118 and continue with: 1183 / 120

Going ahead to step 5:
1183 divided by 120 is 9 with a remainder of 103.
The number 9 becomes the next digit in our result. 
Result so far: 679.0
If we take 1080 away from 1183, we end up with 103.
Append the next digit (6) from the dividend to 103 and continue with: 1036 / 120

Step 6:
120 goes into 1036 8 times with a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 6798.0
If we take 960 away from 1036, we end up with 76.
Include the next digit (6) from the dividend after 76, then repeat: 766 / 120

On to step 7:
When dividing 766 by 120, we get 6 with a remainder of 46.
Use 6 as the next digit of our solution. 
Result so far: 67986.0
The remainder is 46 after subtracting 720 from 766.
Append the next digit (1) from the dividend to 46 and continue with: 461 / 120

Step 8:
The number 120 fits into 461 3 times, leaving a remainder of 101.
Use 3 as the next digit of our solution. 
Result so far: 679863.0
Subtract 360 from 461 to get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Moving on to step 9:
When dividing 1010 by 120, we get 8 with a remainder of 50.
Write down 8 as next digit of the result. 
Result so far: 679863.8
The remainder is 50 after subtracting 960 from 1010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 10:
The number 120 fits into 500 4 times, leaving a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 679863.84
Subtract 480 from 500 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
The number 120 fits into 200 1 times, leaving a remainder of 80.
Put 1 as the next digit of the answer. 
Result so far: 679863.841
If we take 120 away from 200, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 12:
If we divide 800 by 120, we get 6 and a remainder of 80.
The next digit of our result is 6. 
Result so far: 679863.8416
Subtracting 720 from 800 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 13:
800 divided by 120 is 6 with a remainder of 80.
The next digit of our result is 6. 
Result so far: 679863.84166
If we take 720 away from 800, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final result is 679863.84166 with a remainder of 8e-05.
