Let's divide 19581818 by 120
Our goal is to divide 19581818 by 120.

Going ahead to step 1:
When dividing 1 by 120, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 120

Advancing to step 2:
19 divided by 120 is 0 with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Take the next digit (5) from the dividend and append it to 19, then repeat: 195 / 120

Step 3:
When dividing 195 by 120, we get 1 with a remainder of 75.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 120 from 195 leaves us with 75.
Include the next digit (8) from the dividend after 75, then repeat: 758 / 120

Let's proceed to step 4:
The number 120 fits into 758 6 times, leaving a remainder of 38.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
The remainder is 38 after subtracting 720 from 758.
Include the next digit (1) from the dividend after 38, then repeat: 381 / 120

Moving on to step 5:
120 goes into 381 3 times with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 163.0
Subtract 360 from 381 to get 21.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 120

On to step 6:
The number 120 fits into 218 1 times, leaving a remainder of 98.
Record the quotient 1 as the next digit in the result. 
Result so far: 1631.0
If we subtract 120 from 218, we get 98.
Include the next digit (1) from the dividend after 98, then repeat: 981 / 120

Step 7:
The number 120 fits into 981 8 times, leaving a remainder of 21.
Use 8 as the next digit of our solution. 
Result so far: 16318.0
Subtract 960 from 981 to get 21.
Fetch the next digit (8) from the dividend, attach it to 21 and continue: 218 / 120

Let's proceed to step 8:
If we divide 218 by 120, we get 1 and a remainder of 98.
The next digit of our result is 1. 
Result so far: 163181.0
The remainder is 98 after subtracting 120 from 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Let's proceed to step 9:
980 divided by 120 is 8 with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 163181.8
Deduct 960 from 980 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
If we divide 200 by 120, we get 1 and a remainder of 80.
Record the quotient 1 as the next digit in the result. 
Result so far: 163181.81
If we subtract 120 from 200, we get 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 11:
If we divide 800 by 120, we get 6 and a remainder of 80.
Put 6 as the next digit of the answer. 
Result so far: 163181.816
Subtract 720 from 800 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 12:
The number 120 fits into 800 6 times, leaving a remainder of 80.
Put 6 as the next digit of the answer. 
Result so far: 163181.8166
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 163181.8166 with a remainder of 0.0008.
