We divide 120941 by 81
The aim is to understand the frequency of 81 in 120941.

Advancing to step 1:
81 can be fit into 1 0 times, resulting in 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 (2) from the dividend after 1, then repeat: 12 / 81

Step 2:
81 goes into 12 0 times with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 81

On to step 3:
81 goes into 120 1 times with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 81 from 120 and we're left with 39.
Bring next digit (9) of the dividend behind the 39 and repeat the process: 399 / 81

Going ahead to step 4:
81 can be fit into 399 4 times, resulting in a remainder of 75.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Deduct 324 from 399 and we're left with 75.
Take the next digit (4) from the dividend and append it to 75, then repeat: 754 / 81

Let's proceed to step 5:
The number 81 fits into 754 9 times, leaving a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 149.0
The remainder is 25 after subtracting 729 from 754.
Include the next digit (1) from the dividend after 25, then repeat: 251 / 81

Step 6:
81 can be fit into 251 3 times, resulting in a remainder of 8.
The next digit of our result is 3. 
Result so far: 1493.0
Subtract 243 from 251 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
81 goes into 80 0 times with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 1493.0
Subtract 0 from 80 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.

Moving on to step 8:
If we divide 800 by 81, we get 9 and a remainder of 71.
The next digit of our result is 9. 
Result so far: 1493.09
If we subtract 729 from 800, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 9:
When dividing 710 by 81, we get 8 with a remainder of 62.
Write down 8 as next digit of the result. 
Result so far: 1493.098
If we subtract 648 from 710, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 10:
620 divided by 81 is 7 with a remainder of 53.
Put 7 as the next digit of the answer. 
Result so far: 1493.0987
Subtract 567 from 620 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 11:
The number 81 fits into 530 6 times, leaving a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 1493.09876
The remainder is 44 after subtracting 486 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 12:
81 goes into 440 5 times with a remainder of 35.
The next digit of our result is 5. 
Result so far: 1493.098765
If we subtract 405 from 440, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 13:
350 divided by 81 is 4 with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 1493.0987654
Subtract 324 from 350 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 14:
81 goes into 260 3 times with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 1493.09876543
The remainder is 17 after subtracting 243 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

After the division, we end up with 1493.09876543 and a remainder of 1.7e-08.
