We look at the division of 869277 by 61 
The aim is to understand the frequency of 61 in 869277.

Advancing to step 1:
61 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 61

Going ahead to step 2:
86 divided by 61 is 1 with a remainder of 25.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 61 from 86 to get 25.
Append the next digit (9) from the dividend to 25 and continue with: 259 / 61

Step 3:
61 can be fit into 259 4 times, resulting in a remainder of 15.
Write down 4 as next digit of the result. 
Result so far: 14.0
The remainder is 15 after subtracting 244 from 259.
Append the next digit (2) from the dividend to 15 and continue with: 152 / 61

Advancing to step 4:
61 can be fit into 152 2 times, resulting in a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 142.0
Subtract 122 from 152 to get 30.
Grab the next digit (7) from the dividend, add it to 30, then carry on: 307 / 61

Going ahead to step 5:
61 can be fit into 307 5 times, resulting in a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 1425.0
Subtract 305 from 307 to get 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 61

On to step 6:
The number 61 fits into 27 0 times, leaving a remainder of 27.
The next digit of our result is 0. 
Result so far: 14250.0
Subtract 0 from 27 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 7:
The number 61 fits into 270 4 times, leaving a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 14250.4
If we take 244 away from 270, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 8:
61 goes into 260 4 times with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 14250.44
The remainder is 16 after subtracting 244 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 14250.44 and a remainder of 0.016.
