We look at the division of 146513 by 61 
The aim is to understand the frequency of 61 in 146513.

Step 1:
1 divided by 61 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 61

Step 2:
If we divide 14 by 61, we get 0 and a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Include the next digit (6) from the dividend after 14, then repeat: 146 / 61

Advancing to step 3:
61 can be fit into 146 2 times, resulting in a remainder of 24.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 24 after subtracting 122 from 146.
Append the next digit (5) from the dividend to 24 and continue with: 245 / 61

Moving on to step 4:
245 divided by 61 is 4 with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 24.0
Subtract 244 from 245 to get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 61

Advancing to step 5:
When dividing 11 by 61, we get 0 with a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 240.0
Deduct 0 from 11 and we're left with 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 61

Advancing to step 6:
61 can be fit into 113 1 times, resulting in a remainder of 52.
The number 1 becomes the next digit in our result. 
Result so far: 2401.0
Subtracting 61 from 113 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 7:
The number 61 fits into 520 8 times, leaving a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 2401.8
If we take 488 away from 520, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 8:
61 goes into 320 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 2401.85
Subtract 305 from 320 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 9:
If we divide 150 by 61, we get 2 and a remainder of 28.
The next digit of our result is 2. 
Result so far: 2401.852
Subtracting 122 from 150 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
If we divide 280 by 61, we get 4 and a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 2401.8524
Subtracting 244 from 280 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 11:
360 divided by 61 is 5 with a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 2401.85245
If we take 305 away from 360, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 12:
61 goes into 550 9 times with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 2401.852459
Subtracting 549 from 550 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 13:
When dividing 10 by 61, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 2401.852459
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 14:
If we divide 100 by 61, we get 1 and a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 2401.85245901
The remainder is 39 after subtracting 61 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

In conclusion, the division gives 2401.85245901 with a balance of 3.9e-08.
