Let's divide 765660 by 61
The aim is to understand the frequency of 61 in 765660.

Going ahead to step 1:
61 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 61

Going ahead to step 2:
61 goes into 76 1 times with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 15 after subtracting 61 from 76.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 61

On to step 3:
61 can be fit into 155 2 times, resulting in a remainder of 33.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 33 after subtracting 122 from 155.
Take the next digit (6) from the dividend and append it to 33, then repeat: 336 / 61

Moving on to step 4:
336 divided by 61 is 5 with a remainder of 31.
Write down 5 as next digit of the result. 
Result so far: 125.0
If we subtract 305 from 336, we get 31.
Fetch the next digit (6) from the dividend, attach it to 31 and continue: 316 / 61

Moving on to step 5:
316 divided by 61 is 5 with a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 1255.0
Subtracting 305 from 316 leaves us with 11.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 61

On to step 6:
61 can be fit into 110 1 times, resulting in a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 12551.0
The remainder is 49 after subtracting 61 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 7:
If we divide 490 by 61, we get 8 and a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 12551.8
If we take 488 away from 490, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
20 divided by 61 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 12551.8
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
61 goes into 200 3 times with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 12551.803
Subtract 183 from 200 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 10:
170 divided by 61 is 2 with a remainder of 48.
The next digit of our result is 2. 
Result so far: 12551.8032
If we take 122 away from 170, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 11:
The number 61 fits into 480 7 times, leaving a remainder of 53.
The number 7 becomes the next digit in our result. 
Result so far: 12551.80327
If we subtract 427 from 480, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 12:
The number 61 fits into 530 8 times, leaving a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 12551.803278
If we take 488 away from 530, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 13:
The number 61 fits into 420 6 times, leaving a remainder of 54.
The number 6 becomes the next digit in our result. 
Result so far: 12551.8032786
If we subtract 366 from 420, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 14:
540 divided by 61 is 8 with a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 12551.80327868
Subtracting 488 from 540 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final outcome is 12551.80327868, with a leftover of 5.2e-08.
