Let's divide 86866 by 61
The aim is to understand the frequency of 61 in 86866.

Let's proceed to step 1:
The number 61 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 61

Step 2:
61 can be fit into 86 1 times, resulting in a remainder of 25.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 61 from 86, we get 25.
Grab the next digit (8) from the dividend, add it to 25, then carry on: 258 / 61

Advancing to step 3:
The number 61 fits into 258 4 times, leaving a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we take 244 away from 258, we end up with 14.
Grab the next digit (6) from the dividend, add it to 14, then carry on: 146 / 61

Moving on to step 4:
146 divided by 61 is 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 142.0
If we subtract 122 from 146, we get 24.
Include the next digit (6) from the dividend after 24, then repeat: 246 / 61

On to step 5:
61 goes into 246 4 times with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 1424.0
Subtracting 244 from 246 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 6:
20 divided by 61 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 1424.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 7:
If we divide 200 by 61, we get 3 and a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 1424.03
Subtracting 183 from 200 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 8:
The number 61 fits into 170 2 times, leaving a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 1424.032
Subtracting 122 from 170 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 9:
When dividing 480 by 61, we get 7 with a remainder of 53.
Record the quotient 7 as the next digit in the result. 
Result so far: 1424.0327
If we take 427 away from 480, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 10:
The number 61 fits into 530 8 times, leaving a remainder of 42.
The next digit of our result is 8. 
Result so far: 1424.03278
Deduct 488 from 530 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 11:
When dividing 420 by 61, we get 6 with a remainder of 54.
Use 6 as the next digit of our solution. 
Result so far: 1424.032786
If we take 366 away from 420, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 12:
When dividing 540 by 61, we get 8 with a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 1424.0327868
Subtracting 488 from 540 leaves us 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.

Moving on to step 13:
When dividing 520 by 61, we get 8 with a remainder of 32.
The next digit of our result is 8. 
Result so far: 1424.03278688
If we take 488 away from 520, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 1424.03278688, with a leftover of 3.2e-08.
