We're dividing 23378173 by 120 
The aim is to understand the frequency of 120 in 23378173.

On to step 1:
If we divide 2 by 120, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 120

On to step 2:
The number 120 fits into 23 0 times, leaving a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Include the next digit (3) from the dividend after 23, then repeat: 233 / 120

Moving on to step 3:
When dividing 233 by 120, we get 1 with a remainder of 113.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 120 from 233 leaves us with 113.
Include the next digit (7) from the dividend after 113, then repeat: 1137 / 120

Advancing to step 4:
120 can be fit into 1137 9 times, resulting in a remainder of 57.
The next digit of our result is 9. 
Result so far: 19.0
The remainder is 57 after subtracting 1080 from 1137.
Take the next digit (8) from the dividend and append it to 57, then repeat: 578 / 120

Let's proceed to step 5:
If we divide 578 by 120, we get 4 and a remainder of 98.
The next digit of our result is 4. 
Result so far: 194.0
If we subtract 480 from 578, we get 98.
Bring next digit (1) of the dividend behind the 98 and repeat the process: 981 / 120

Advancing to step 6:
The number 120 fits into 981 8 times, leaving a remainder of 21.
Record the quotient 8 as the next digit in the result. 
Result so far: 1948.0
Subtract 960 from 981 to get 21.
Fetch the next digit (7) from the dividend, attach it to 21 and continue: 217 / 120

Moving on to step 7:
120 goes into 217 1 times with a remainder of 97.
Record the quotient 1 as the next digit in the result. 
Result so far: 19481.0
Subtracting 120 from 217 leaves us with 97.
Take the next digit (3) from the dividend and append it to 97, then repeat: 973 / 120

On to step 8:
When dividing 973 by 120, we get 8 with a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 194818.0
The remainder is 13 after subtracting 960 from 973.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 9:
120 can be fit into 130 1 times, resulting in a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 194818.1
Deduct 120 from 130 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
100 divided by 120 is 0 with a remainder of 100.
The next digit of our result is 0. 
Result so far: 194818.1
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 11:
If we divide 1000 by 120, we get 8 and a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 194818.108
The remainder is 40 after subtracting 960 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
120 goes into 400 3 times with a remainder of 40.
The number 3 becomes the next digit in our result. 
Result so far: 194818.1083
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
120 can be fit into 400 3 times, resulting in a remainder of 40.
Record the quotient 3 as the next digit in the result. 
Result so far: 194818.10833
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 194818.10833 and a remainder of 4e-05.
