64945 ÷ 61 
The aim is to understand the frequency of 61 in 64945.

Step 1:
6 divided by 61 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 61

Moving on to step 2:
If we divide 64 by 61, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 61 from 64 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 61

Going ahead to step 3:
61 can be fit into 39 0 times, resulting in a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 39, we end up with 39.
Include the next digit (4) from the dividend after 39, then repeat: 394 / 61

Step 4:
61 goes into 394 6 times with a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 106.0
If we subtract 366 from 394, we get 28.
Take the next digit (5) from the dividend and append it to 28, then repeat: 285 / 61

Going ahead to step 5:
61 can be fit into 285 4 times, resulting in a remainder of 41.
The number 4 becomes the next digit in our result. 
Result so far: 1064.0
If we subtract 244 from 285, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 6:
410 divided by 61 is 6 with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 1064.6
Subtract 366 from 410 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 7:
440 divided by 61 is 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 1064.67
If we subtract 427 from 440, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 8:
130 divided by 61 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 1064.672
If we subtract 122 from 130, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
80 divided by 61 is 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 1064.6721
If we subtract 61 from 80, we 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 10:
190 divided by 61 is 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 1064.67213
Deduct 183 from 190 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 11:
61 goes into 70 1 times with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1064.672131
Deduct 61 from 70 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 12:
If we divide 90 by 61, we get 1 and a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 1064.6721311
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.

The final outcome is 1064.6721311, with a leftover of 2.9e-07.
