We look at the division of 817254 by 61 
The aim is to understand the frequency of 61 in 817254.

Step 1:
61 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 61

Advancing to step 2:
61 can be fit into 81 1 times, resulting in a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 61 away from 81, we end up with 20.
Fetch the next digit (7) from the dividend, attach it to 20 and continue: 207 / 61

Moving on to step 3:
The number 61 fits into 207 3 times, leaving a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtract 183 from 207 to get 24.
Include the next digit (2) from the dividend after 24, then repeat: 242 / 61

Step 4:
61 goes into 242 3 times with a remainder of 59.
Record the quotient 3 as the next digit in the result. 
Result so far: 133.0
Deduct 183 from 242 and we're left with 59.
Bring next digit (5) of the dividend behind the 59 and repeat the process: 595 / 61

Let's proceed to step 5:
595 divided by 61 is 9 with a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 1339.0
The remainder is 46 after subtracting 549 from 595.
Grab the next digit (4) from the dividend, add it to 46, then carry on: 464 / 61

Advancing to step 6:
When dividing 464 by 61, we get 7 with a remainder of 37.
The next digit of our result is 7. 
Result so far: 13397.0
Deduct 427 from 464 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 7:
61 can be fit into 370 6 times, resulting in a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 13397.6
If we subtract 366 from 370, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
The number 61 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 13397.6
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
The number 61 fits into 400 6 times, leaving a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 13397.606
If we take 366 away from 400, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 10:
If we divide 340 by 61, we get 5 and a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 13397.6065
Subtract 305 from 340 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 11:
61 goes into 350 5 times with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 13397.60655
Deduct 305 from 350 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final outcome is 13397.60655, with a leftover of 4.5e-05.
