We divide 855875 by 64
The aim is to understand the frequency of 64 in 855875.

Step 1:
If we divide 8 by 64, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 64

Let's proceed to step 2:
64 can be fit into 85 1 times, resulting in a remainder of 21.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 64 from 85 leaves us with 21.
Fetch the next digit (5) from the dividend, attach it to 21 and continue: 215 / 64

On to step 3:
64 can be fit into 215 3 times, resulting in a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Deduct 192 from 215 and we're left with 23.
Bring next digit (8) of the dividend behind the 23 and repeat the process: 238 / 64

Going ahead to step 4:
If we divide 238 by 64, we get 3 and a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 133.0
Deduct 192 from 238 and we're left with 46.
Bring next digit (7) of the dividend behind the 46 and repeat the process: 467 / 64

On to step 5:
When dividing 467 by 64, we get 7 with a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 1337.0
Deduct 448 from 467 and we're left with 19.
Fetch the next digit (5) from the dividend, attach it to 19 and continue: 195 / 64

Advancing to step 6:
The number 64 fits into 195 3 times, leaving a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 13373.0
Deduct 192 from 195 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
When dividing 30 by 64, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 13373.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
If we divide 300 by 64, we get 4 and a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 13373.04
Subtract 256 from 300 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.

On to step 9:
When dividing 440 by 64, we get 6 with a remainder of 56.
Record the quotient 6 as the next digit in the result. 
Result so far: 13373.046
If we subtract 384 from 440, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 10:
The number 64 fits into 560 8 times, leaving a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 13373.0468
If we take 512 away from 560, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 11:
The number 64 fits into 480 7 times, leaving a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 13373.04687
If we take 448 away from 480, 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.

Step 12:
320 divided by 64 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 13373.046875
If we subtract 320 from 320, 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.

Going ahead to step 13:
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: 13373.046875
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.

Going ahead to step 14:
0 divided by 64 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 13373.046875
Deduct 0 from 0 and we're left 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.

The final outcome is 13373.046875, with a leftover of 0.0.
