548215 ÷ 61 
The aim is to understand the frequency of 61 in 548215.

On to step 1:
61 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 61

Moving on to step 2:
The number 61 fits into 54 0 times, leaving a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Bring next digit (8) of the dividend behind the 54 and repeat the process: 548 / 61

Advancing to step 3:
61 goes into 548 8 times with a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 60 after subtracting 488 from 548.
Grab the next digit (2) from the dividend, add it to 60, then carry on: 602 / 61

Let's proceed to step 4:
602 divided by 61 is 9 with a remainder of 53.
Record the quotient 9 as the next digit in the result. 
Result so far: 89.0
If we take 549 away from 602, we end up with 53.
Bring next digit (1) of the dividend behind the 53 and repeat the process: 531 / 61

Advancing to step 5:
61 can be fit into 531 8 times, resulting in a remainder of 43.
The next digit of our result is 8. 
Result so far: 898.0
Subtracting 488 from 531 leaves us with 43.
Include the next digit (5) from the dividend after 43, then repeat: 435 / 61

On to step 6:
When dividing 435 by 61, we get 7 with a remainder of 8.
The next digit of our result is 7. 
Result so far: 8987.0
The remainder is 8 after subtracting 427 from 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
If we divide 80 by 61, we get 1 and a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 8987.1
Subtracting 61 from 80 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 8:
61 goes into 190 3 times with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 8987.13
Subtracting 183 from 190 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 9:
61 goes into 70 1 times with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 8987.131
The remainder is 9 after subtracting 61 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 10:
The number 61 fits into 90 1 times, leaving a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 8987.1311
Subtract 61 from 90 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final outcome is 8987.1311, with a leftover of 0.00029.
