We're dividing 64510 by 61 
The aim is to understand the frequency of 61 in 64510.

Going ahead to step 1:
When dividing 6 by 61, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 61

Moving on to step 2:
64 divided by 61 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 61 away from 64, we end up with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 61

Let's proceed to step 3:
When dividing 35 by 61, we get 0 with a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 35 after subtracting 0 from 35.
Include the next digit (1) from the dividend after 35, then repeat: 351 / 61

Step 4:
351 divided by 61 is 5 with a remainder of 46.
The number 5 becomes the next digit in our result. 
Result so far: 105.0
Deduct 305 from 351 and we're left with 46.
Take the next digit (0) from the dividend and append it to 46, then repeat: 460 / 61

On to step 5:
The number 61 fits into 460 7 times, leaving a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 1057.0
The remainder is 33 after subtracting 427 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 6:
61 goes into 330 5 times with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 1057.5
If we take 305 away from 330, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 7:
61 goes into 250 4 times with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 1057.54
The remainder is 6 after subtracting 244 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
The number 61 fits into 60 0 times, leaving a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 1057.54
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 9:
61 goes into 600 9 times with a remainder of 51.
The number 9 becomes the next digit in our result. 
Result so far: 1057.5409
If we take 549 away from 600, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 10:
61 can be fit into 510 8 times, resulting in a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 1057.54098
Subtract 488 from 510 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 11:
220 divided by 61 is 3 with a remainder of 37.
The next digit of our result is 3. 
Result so far: 1057.540983
If we take 183 away from 220, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 12:
370 divided by 61 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 1057.5409836
The remainder is 4 after subtracting 366 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 13:
61 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 1057.5409836
Subtracting 0 from 40 leaves us 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.

The quotient of the division is 1057.5409836, and the remainder is 4e-08.
