We look at the division of 18105393 by 120 
The aim is to understand the frequency of 120 in 18105393.

Going ahead to step 1:
120 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 120

Let's proceed to step 2:
If we divide 18 by 120, we get 0 and a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Grab the next digit (1) from the dividend, add it to 18, then carry on: 181 / 120

Step 3:
If we divide 181 by 120, we get 1 and a remainder of 61.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 120 away from 181, we end up with 61.
Include the next digit (0) from the dividend after 61, then repeat: 610 / 120

Let's proceed to step 4:
120 goes into 610 5 times with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Deduct 600 from 610 and we're left with 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 120

Step 5:
120 goes into 105 0 times with a remainder of 105.
Record the quotient 0 as the next digit in the result. 
Result so far: 150.0
If we take 0 away from 105, we end up with 105.
Grab the next digit (3) from the dividend, add it to 105, then carry on: 1053 / 120

Moving on to step 6:
120 goes into 1053 8 times with a remainder of 93.
Put 8 as the next digit of the answer. 
Result so far: 1508.0
Subtract 960 from 1053 to get 93.
Include the next digit (9) from the dividend after 93, then repeat: 939 / 120

Step 7:
120 goes into 939 7 times with a remainder of 99.
Put 7 as the next digit of the answer. 
Result so far: 15087.0
Subtract 840 from 939 to get 99.
Append the next digit (3) from the dividend to 99 and continue with: 993 / 120

Let's proceed to step 8:
120 can be fit into 993 8 times, resulting in a remainder of 33.
Write down 8 as next digit of the result. 
Result so far: 150878.0
If we subtract 960 from 993, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 9:
120 goes into 330 2 times with a remainder of 90.
The next digit of our result is 2. 
Result so far: 150878.2
If we subtract 240 from 330, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 10:
If we divide 900 by 120, we get 7 and a remainder of 60.
The next digit of our result is 7. 
Result so far: 150878.27
The remainder is 60 after subtracting 840 from 900.
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: 150878.275
The remainder is 0 after subtracting 600 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 12:
120 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 150878.275
Deduct 0 from 0 and we're left 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.

Step 13:
The number 120 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 150878.275
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.

The quotient of the division is 150878.275, and the remainder is 0.0.
