Let's divide 61227181 by 321
The aim is to understand the frequency of 321 in 61227181.

Moving on to step 1:
321 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 321

Going ahead to step 2:
61 divided by 321 is 0 with a remainder of 61.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 61, we get 61.
Take the next digit (2) from the dividend and append it to 61, then repeat: 612 / 321

Advancing to step 3:
612 divided by 321 is 1 with a remainder of 291.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 321 from 612, we get 291.
Take the next digit (2) from the dividend and append it to 291, then repeat: 2912 / 321

Step 4:
When dividing 2912 by 321, we get 9 with a remainder of 23.
The next digit of our result is 9. 
Result so far: 19.0
Deduct 2889 from 2912 and we're left with 23.
Include the next digit (7) from the dividend after 23, then repeat: 237 / 321

Going ahead to step 5:
237 divided by 321 is 0 with a remainder of 237.
Use 0 as the next digit of our solution. 
Result so far: 190.0
Subtracting 0 from 237 leaves us with 237.
Grab the next digit (1) from the dividend, add it to 237, then carry on: 2371 / 321

Let's proceed to step 6:
When dividing 2371 by 321, we get 7 with a remainder of 124.
Write down 7 as next digit of the result. 
Result so far: 1907.0
The remainder is 124 after subtracting 2247 from 2371.
Bring next digit (8) of the dividend behind the 124 and repeat the process: 1248 / 321

Advancing to step 7:
1248 divided by 321 is 3 with a remainder of 285.
The number 3 becomes the next digit in our result. 
Result so far: 19073.0
If we take 963 away from 1248, we end up with 285.
Append the next digit (1) from the dividend to 285 and continue with: 2851 / 321

Moving on to step 8:
321 can be fit into 2851 8 times, resulting in a remainder of 283.
Use 8 as the next digit of our solution. 
Result so far: 190738.0
If we take 2568 away from 2851, we end up with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Going ahead to step 9:
321 can be fit into 2830 8 times, resulting in a remainder of 262.
Record the quotient 8 as the next digit in the result. 
Result so far: 190738.8
If we take 2568 away from 2830, we end up with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Let's proceed to step 10:
The number 321 fits into 2620 8 times, leaving a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 190738.88
Deduct 2568 from 2620 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final result is 190738.88 with a remainder of 0.052.
