We're dividing 852624 by 61 
The aim is to understand the frequency of 61 in 852624.

On to step 1:
The number 61 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 61

Advancing to step 2:
When dividing 85 by 61, we get 1 with a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 24 after subtracting 61 from 85.
Include the next digit (2) from the dividend after 24, then repeat: 242 / 61

Going ahead to step 3:
61 goes into 242 3 times with a remainder of 59.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 183 from 242 leaves us with 59.
Bring next digit (6) of the dividend behind the 59 and repeat the process: 596 / 61

Let's proceed to step 4:
The number 61 fits into 596 9 times, leaving a remainder of 47.
Put 9 as the next digit of the answer. 
Result so far: 139.0
The remainder is 47 after subtracting 549 from 596.
Grab the next digit (2) from the dividend, add it to 47, then carry on: 472 / 61

Step 5:
61 can be fit into 472 7 times, resulting in a remainder of 45.
Use 7 as the next digit of our solution. 
Result so far: 1397.0
Deduct 427 from 472 and we're left with 45.
Grab the next digit (4) from the dividend, add it to 45, then carry on: 454 / 61

Moving on to step 6:
454 divided by 61 is 7 with a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 13977.0
The remainder is 27 after subtracting 427 from 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 7:
If we divide 270 by 61, we get 4 and a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 13977.4
If we subtract 244 from 270, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 8:
When dividing 260 by 61, we get 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 13977.44
Subtracting 244 from 260 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 13977.44, and the remainder is 0.016.
