We look at the division of 654187 by 61 
The aim is to understand the frequency of 61 in 654187.

On to step 1:
6 divided by 61 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 61

Step 2:
61 can be fit into 65 1 times, resulting in a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 4 after subtracting 61 from 65.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 61

Advancing to step 3:
The number 61 fits into 44 0 times, leaving a remainder of 44.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 44 and we're left with 44.
Take the next digit (1) from the dividend and append it to 44, then repeat: 441 / 61

Advancing to step 4:
The number 61 fits into 441 7 times, leaving a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 107.0
The remainder is 14 after subtracting 427 from 441.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 61

Moving on to step 5:
61 can be fit into 148 2 times, resulting in a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 1072.0
Deduct 122 from 148 and we're left with 26.
Fetch the next digit (7) from the dividend, attach it to 26 and continue: 267 / 61

Advancing to step 6:
The number 61 fits into 267 4 times, leaving a remainder of 23.
The number 4 becomes the next digit in our result. 
Result so far: 10724.0
If we subtract 244 from 267, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 7:
When dividing 230 by 61, we get 3 with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 10724.3
Subtracting 183 from 230 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 8:
The number 61 fits into 470 7 times, leaving a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 10724.37
Deduct 427 from 470 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 9:
The number 61 fits into 430 7 times, leaving a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 10724.377
Subtracting 427 from 430 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final outcome is 10724.377, with a leftover of 0.0003.
