We look at the division of 396401 by 61 
The aim is to understand the frequency of 61 in 396401.

Moving on to step 1:
When dividing 3 by 61, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 61

Moving on to step 2:
61 goes into 39 0 times with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Bring next digit (6) of the dividend behind the 39 and repeat the process: 396 / 61

Advancing to step 3:
When dividing 396 by 61, we get 6 with a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 366 from 396 and we're left with 30.
Include the next digit (4) from the dividend after 30, then repeat: 304 / 61

Step 4:
61 can be fit into 304 4 times, resulting in a remainder of 60.
Use 4 as the next digit of our solution. 
Result so far: 64.0
Subtract 244 from 304 to get 60.
Fetch the next digit (0) from the dividend, attach it to 60 and continue: 600 / 61

Step 5:
If we divide 600 by 61, we get 9 and a remainder of 51.
The next digit of our result is 9. 
Result so far: 649.0
If we subtract 549 from 600, we get 51.
Grab the next digit (1) from the dividend, add it to 51, then carry on: 511 / 61

On to step 6:
When dividing 511 by 61, we get 8 with a remainder of 23.
The number 8 becomes the next digit in our result. 
Result so far: 6498.0
Subtracting 488 from 511 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.

Advancing to step 7:
230 divided by 61 is 3 with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 6498.3
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.

Step 8:
If we divide 470 by 61, we get 7 and a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 6498.37
The remainder is 43 after subtracting 427 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 9:
The number 61 fits into 430 7 times, leaving a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 6498.377
Subtract 427 from 430 to get 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 result is 6498.377 with a remainder of 0.0003.
