We look at the division of 717580 by 61 
The aim is to understand the frequency of 61 in 717580.

Step 1:
When dividing 7 by 61, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 61

Moving on to step 2:
When dividing 71 by 61, we get 1 with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 61 away from 71, we end up with 10.
Bring next digit (7) of the dividend behind the 10 and repeat the process: 107 / 61

Advancing to step 3:
If we divide 107 by 61, we get 1 and a remainder of 46.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 61 from 107 and we're left with 46.
Append the next digit (5) from the dividend to 46 and continue with: 465 / 61

Let's proceed to step 4:
465 divided by 61 is 7 with a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 117.0
The remainder is 38 after subtracting 427 from 465.
Append the next digit (8) from the dividend to 38 and continue with: 388 / 61

On to step 5:
61 goes into 388 6 times with a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 1176.0
The remainder is 22 after subtracting 366 from 388.
Take the next digit (0) from the dividend and append it to 22, then repeat: 220 / 61

Step 6:
When dividing 220 by 61, we get 3 with a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 11763.0
Deduct 183 from 220 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.

Moving on to step 7:
61 can be fit into 370 6 times, resulting in a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 11763.6
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.

Going ahead to step 8:
When dividing 40 by 61, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 11763.6
The remainder is 40 after subtracting 0 from 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:
400 divided by 61 is 6 with a remainder of 34.
The next digit of our result is 6. 
Result so far: 11763.606
The remainder is 34 after subtracting 366 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 10:
The number 61 fits into 340 5 times, leaving a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 11763.6065
If we subtract 305 from 340, we 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.

Step 11:
When dividing 350 by 61, we get 5 with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 11763.60655
If we take 305 away from 350, we end up 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.

In conclusion, the division gives 11763.60655 with a balance of 4.5e-05.
