860515 ÷ 61 
The aim is to understand the frequency of 61 in 860515.

Moving on to step 1:
61 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 61

On to step 2:
If we divide 86 by 61, we get 1 and a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 61 from 86 to get 25.
Grab the next digit (0) from the dividend, add it to 25, then carry on: 250 / 61

Let's proceed to step 3:
61 can be fit into 250 4 times, resulting in a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtract 244 from 250 to get 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 61

Step 4:
61 goes into 65 1 times with a remainder of 4.
The next digit of our result is 1. 
Result so far: 141.0
Subtract 61 from 65 to get 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 61

Moving on to step 5:
The number 61 fits into 41 0 times, leaving a remainder of 41.
Put 0 as the next digit of the answer. 
Result so far: 1410.0
If we take 0 away from 41, we end up with 41.
Fetch the next digit (5) from the dividend, attach it to 41 and continue: 415 / 61

Step 6:
If we divide 415 by 61, we get 6 and a remainder of 49.
Write down 6 as next digit of the result. 
Result so far: 14106.0
If we take 366 away from 415, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 7:
490 divided by 61 is 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 14106.8
Subtract 488 from 490 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
When dividing 20 by 61, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 14106.8
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.

Going ahead to step 9:
If we divide 200 by 61, we get 3 and a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 14106.803
Deduct 183 from 200 and we're left 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 10:
170 divided by 61 is 2 with a remainder of 48.
The next digit of our result is 2. 
Result so far: 14106.8032
If we subtract 122 from 170, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 11:
61 goes into 480 7 times with a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 14106.80327
Subtracting 427 from 480 leaves us 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.

Moving on to step 12:
If we divide 530 by 61, we get 8 and a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 14106.803278
Subtracting 488 from 530 leaves us 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.

Advancing to step 13:
The number 61 fits into 420 6 times, leaving a remainder of 54.
Put 6 as the next digit of the answer. 
Result so far: 14106.8032786
Subtracting 366 from 420 leaves us 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.

Moving on to step 14:
When dividing 540 by 61, we get 8 with a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 14106.80327868
If we subtract 488 from 540, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Our division results in 14106.80327868 with a remaining 5.2e-08.
