We look at the division of 39602 by 61 
The aim is to understand the frequency of 61 in 39602.

Moving on to step 1:
3 divided by 61 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 61

Going ahead to step 2:
39 divided by 61 is 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Take the next digit (6) from the dividend and append it to 39, then repeat: 396 / 61

On to step 3:
61 goes into 396 6 times with a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 30 after subtracting 366 from 396.
Take the next digit (0) from the dividend and append it to 30, then repeat: 300 / 61

Advancing to step 4:
61 goes into 300 4 times with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
Subtracting 244 from 300 leaves us with 56.
Bring next digit (2) of the dividend behind the 56 and repeat the process: 562 / 61

Going ahead to step 5:
61 can be fit into 562 9 times, resulting in a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 649.0
Subtracting 549 from 562 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 6:
When dividing 130 by 61, we get 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 649.2
Subtracting 122 from 130 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
If we divide 80 by 61, we get 1 and a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 649.21
Subtract 61 from 80 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 8:
61 goes into 190 3 times with a remainder of 7.
The next digit of our result is 3. 
Result so far: 649.213
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.

Let's proceed to step 9:
The number 61 fits into 70 1 times, leaving a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 649.2131
The remainder is 9 after subtracting 61 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 10:
The number 61 fits into 90 1 times, leaving a remainder of 29.
The next digit of our result is 1. 
Result so far: 649.21311
Deduct 61 from 90 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

In conclusion, the division gives 649.21311 with a balance of 2.9e-05.
