Let's divide 777917 by 61
The aim is to understand the frequency of 61 in 777917.

Step 1:
The number 61 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 61

Going ahead to step 2:
When dividing 77 by 61, we get 1 with a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 61 from 77 to get 16.
Bring next digit (7) of the dividend behind the 16 and repeat the process: 167 / 61

Moving on to step 3:
The number 61 fits into 167 2 times, leaving a remainder of 45.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 122 from 167 to get 45.
Append the next digit (9) from the dividend to 45 and continue with: 459 / 61

On to step 4:
When dividing 459 by 61, we get 7 with a remainder of 32.
Write down 7 as next digit of the result. 
Result so far: 127.0
Subtract 427 from 459 to get 32.
Include the next digit (1) from the dividend after 32, then repeat: 321 / 61

Moving on to step 5:
61 goes into 321 5 times with a remainder of 16.
Put 5 as the next digit of the answer. 
Result so far: 1275.0
The remainder is 16 after subtracting 305 from 321.
Take the next digit (7) from the dividend and append it to 16, then repeat: 167 / 61

Moving on to step 6:
If we divide 167 by 61, we get 2 and a remainder of 45.
The number 2 becomes the next digit in our result. 
Result so far: 12752.0
Subtract 122 from 167 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 7:
61 goes into 450 7 times with a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 12752.7
Subtracting 427 from 450 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 8:
61 goes into 230 3 times with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 12752.73
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.

Moving on to step 9:
61 can be fit into 470 7 times, resulting in a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 12752.737
Deduct 427 from 470 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 10:
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: 12752.7377
The remainder is 3 after subtracting 427 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

After the division, we end up with 12752.7377 and a remainder of 3e-05.
