397968 ÷ 61 
The aim is to understand the frequency of 61 in 397968.

Going ahead to step 1:
3 divided by 61 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 61

Step 2:
61 goes into 39 0 times with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Include the next digit (7) from the dividend after 39, then repeat: 397 / 61

Going ahead to step 3:
61 can be fit into 397 6 times, resulting in a remainder of 31.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 366 away from 397, we end up with 31.
Fetch the next digit (9) from the dividend, attach it to 31 and continue: 319 / 61

Advancing to step 4:
The number 61 fits into 319 5 times, leaving a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 65.0
Subtracting 305 from 319 leaves us with 14.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 61

Going ahead to step 5:
146 divided by 61 is 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 652.0
Deduct 122 from 146 and we're left with 24.
Include the next digit (8) from the dividend after 24, then repeat: 248 / 61

Going ahead to step 6:
The number 61 fits into 248 4 times, leaving a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 6524.0
Subtracting 244 from 248 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
61 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 6524.0
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
61 can be fit into 400 6 times, resulting in a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 6524.06
Subtract 366 from 400 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 9:
If we divide 340 by 61, we get 5 and a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 6524.065
The remainder is 35 after subtracting 305 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 10:
350 divided by 61 is 5 with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 6524.0655
Subtracting 305 from 350 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

After the division, we end up with 6524.0655 and a remainder of 0.00045.
