517242 divided by 61 
The aim is to understand the frequency of 61 in 517242.

Let's proceed to step 1:
The number 61 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 61

Advancing to step 2:
51 divided by 61 is 0 with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Take the next digit (7) from the dividend and append it to 51, then repeat: 517 / 61

Step 3:
517 divided by 61 is 8 with a remainder of 29.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 488 from 517 and we're left with 29.
Bring next digit (2) of the dividend behind the 29 and repeat the process: 292 / 61

Going ahead to step 4:
61 goes into 292 4 times with a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
If we take 244 away from 292, we end up with 48.
Include the next digit (4) from the dividend after 48, then repeat: 484 / 61

Moving on to step 5:
If we divide 484 by 61, we get 7 and a remainder of 57.
The next digit of our result is 7. 
Result so far: 847.0
Subtract 427 from 484 to get 57.
Fetch the next digit (2) from the dividend, attach it to 57 and continue: 572 / 61

On to step 6:
61 goes into 572 9 times with a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 8479.0
If we subtract 549 from 572, 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.

Advancing to step 7:
61 goes into 230 3 times with a remainder of 47.
The next digit of our result is 3. 
Result so far: 8479.3
Subtract 183 from 230 to get 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:
If we divide 470 by 61, we get 7 and a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 8479.37
If we subtract 427 from 470, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 9:
The number 61 fits into 430 7 times, leaving a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 8479.377
Deduct 427 from 430 and we're left 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 8479.377, with a leftover of 0.0003.
