801634 divided by 64 
The aim is to understand the frequency of 64 in 801634.

Going ahead to step 1:
8 divided by 64 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 64

Advancing to step 2:
If we divide 80 by 64, we get 1 and a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 64 away from 80, we end up with 16.
Bring next digit (1) of the dividend behind the 16 and repeat the process: 161 / 64

On to step 3:
161 divided by 64 is 2 with a remainder of 33.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 128 from 161 leaves us with 33.
Fetch the next digit (6) from the dividend, attach it to 33 and continue: 336 / 64

Going ahead to step 4:
The number 64 fits into 336 5 times, leaving a remainder of 16.
The next digit of our result is 5. 
Result so far: 125.0
If we subtract 320 from 336, we get 16.
Append the next digit (3) from the dividend to 16 and continue with: 163 / 64

On to step 5:
The number 64 fits into 163 2 times, leaving a remainder of 35.
Record the quotient 2 as the next digit in the result. 
Result so far: 1252.0
If we subtract 128 from 163, we get 35.
Include the next digit (4) from the dividend after 35, then repeat: 354 / 64

Step 6:
The number 64 fits into 354 5 times, leaving a remainder of 34.
The next digit of our result is 5. 
Result so far: 12525.0
If we subtract 320 from 354, we 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.

Moving on to step 7:
If we divide 340 by 64, we get 5 and a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 12525.5
If we take 320 away from 340, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
The number 64 fits into 200 3 times, leaving a remainder of 8.
The next digit of our result is 3. 
Result so far: 12525.53
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.

Going ahead to step 9:
64 can be fit into 80 1 times, resulting in a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 12525.531
If we take 64 away from 80, we end up 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.

Going ahead to step 10:
64 goes into 160 2 times with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 12525.5312
Deduct 128 from 160 and we're left 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.

On to step 11:
64 can be fit into 320 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 12525.53125
If we take 320 away from 320, we end up 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.

On to step 12:
When dividing 0 by 64, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12525.53125
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.

Going ahead to step 13:
0 divided by 64 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12525.53125
If we take 0 away from 0, we end up 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 12525.53125, with a leftover of 0.0.
