We look at the division of 68421914 by 61 
The aim is to understand the frequency of 61 in 68421914.

Going ahead to step 1:
If we divide 6 by 61, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 61

Moving on to step 2:
If we divide 68 by 61, we get 1 and a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 7 after subtracting 61 from 68.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 61

Moving on to step 3:
The number 61 fits into 74 1 times, leaving a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 13 after subtracting 61 from 74.
Append the next digit (2) from the dividend to 13 and continue with: 132 / 61

Advancing to step 4:
The number 61 fits into 132 2 times, leaving a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 112.0
The remainder is 10 after subtracting 122 from 132.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 61

Advancing to step 5:
The number 61 fits into 101 1 times, leaving a remainder of 40.
Use 1 as the next digit of our solution. 
Result so far: 1121.0
Subtract 61 from 101 to get 40.
Take the next digit (9) from the dividend and append it to 40, then repeat: 409 / 61

On to step 6:
When dividing 409 by 61, we get 6 with a remainder of 43.
Record the quotient 6 as the next digit in the result. 
Result so far: 11216.0
If we subtract 366 from 409, we get 43.
Fetch the next digit (1) from the dividend, attach it to 43 and continue: 431 / 61

Moving on to step 7:
The number 61 fits into 431 7 times, leaving a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 112167.0
Subtracting 427 from 431 leaves us with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 61

Going ahead to step 8:
61 goes into 44 0 times with a remainder of 44.
Write down 0 as next digit of the result. 
Result so far: 1121670.0
Subtract 0 from 44 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
If we divide 440 by 61, we get 7 and a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 1121670.7
Subtract 427 from 440 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 10:
61 can be fit into 130 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 1121670.72
The remainder is 8 after subtracting 122 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
80 divided by 61 is 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 1121670.721
The remainder is 19 after subtracting 61 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 12:
If we divide 190 by 61, we get 3 and a remainder of 7.
The next digit of our result is 3. 
Result so far: 1121670.7213
Subtract 183 from 190 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 13:
When dividing 70 by 61, we get 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1121670.72131
If we subtract 61 from 70, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 14:
61 goes into 90 1 times with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 1121670.721311
Subtract 61 from 90 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final result is 1121670.721311 with a remainder of 2.9e-06.
