We look at the division of 159906 by 64 
The aim is to understand the frequency of 64 in 159906.

Moving on to step 1:
When dividing 1 by 64, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 64

Moving on to step 2:
If we divide 15 by 64, we get 0 and a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 64

Step 3:
64 goes into 159 2 times with a remainder of 31.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 128 from 159 leaves us with 31.
Take the next digit (9) from the dividend and append it to 31, then repeat: 319 / 64

Going ahead to step 4:
When dividing 319 by 64, we get 4 with a remainder of 63.
Use 4 as the next digit of our solution. 
Result so far: 24.0
Subtract 256 from 319 to get 63.
Append the next digit (0) from the dividend to 63 and continue with: 630 / 64

Step 5:
630 divided by 64 is 9 with a remainder of 54.
The number 9 becomes the next digit in our result. 
Result so far: 249.0
Subtract 576 from 630 to get 54.
Include the next digit (6) from the dividend after 54, then repeat: 546 / 64

Advancing to step 6:
546 divided by 64 is 8 with a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 2498.0
Subtract 512 from 546 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.

On to step 7:
If we divide 340 by 64, we get 5 and a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 2498.5
The remainder is 20 after subtracting 320 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
200 divided by 64 is 3 with a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 2498.53
Subtracting 192 from 200 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.

On to step 9:
80 divided by 64 is 1 with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 2498.531
Subtracting 64 from 80 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 10:
64 goes into 160 2 times with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 2498.5312
If we subtract 128 from 160, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 11:
64 can be fit into 320 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 2498.53125
Subtracting 320 from 320 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
64 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2498.53125
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 13:
64 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2498.53125
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 2498.53125, with a leftover of 0.0.
