868579 divided by 61 
The aim is to understand the frequency of 61 in 868579.

Step 1:
If we divide 8 by 61, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 61

On to step 2:
61 goes into 86 1 times with a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 61 from 86 and we're left with 25.
Fetch the next digit (8) from the dividend, attach it to 25 and continue: 258 / 61

Going ahead to step 3:
When dividing 258 by 61, we get 4 with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we subtract 244 from 258, we get 14.
Append the next digit (5) from the dividend to 14 and continue with: 145 / 61

Moving on to step 4:
61 can be fit into 145 2 times, resulting in a remainder of 23.
Write down 2 as next digit of the result. 
Result so far: 142.0
Subtract 122 from 145 to get 23.
Take the next digit (7) from the dividend and append it to 23, then repeat: 237 / 61

On to step 5:
If we divide 237 by 61, we get 3 and a remainder of 54.
Put 3 as the next digit of the answer. 
Result so far: 1423.0
If we take 183 away from 237, we end up with 54.
Fetch the next digit (9) from the dividend, attach it to 54 and continue: 549 / 61

Moving on to step 6:
61 can be fit into 549 9 times, resulting in a remainder of 0.
The next digit of our result is 9. 
Result so far: 14239.0
Subtract 549 from 549 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
The number 61 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 14239.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
61 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 14239.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 14239.0 and a remainder of 0.0.
