We divide 643271 by 64
The aim is to understand the frequency of 64 in 643271.

Advancing to step 1:
If we divide 6 by 64, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 64

Moving on to step 2:
When dividing 64 by 64, we get 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 64 from 64 and we're left with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 64

Moving on to step 3:
If we divide 3 by 64, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 3, we get 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 64

Advancing to step 4:
If we divide 32 by 64, we get 0 and a remainder of 32.
Write down 0 as next digit of the result. 
Result so far: 100.0
Deduct 0 from 32 and we're left with 32.
Fetch the next digit (7) from the dividend, attach it to 32 and continue: 327 / 64

On to step 5:
64 goes into 327 5 times with a remainder of 7.
Use 5 as the next digit of our solution. 
Result so far: 1005.0
The remainder is 7 after subtracting 320 from 327.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 64

Let's proceed to step 6:
When dividing 71 by 64, we get 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 10051.0
The remainder is 7 after subtracting 64 from 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
64 can be fit into 70 1 times, resulting in a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 10051.1
Deduct 64 from 70 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
64 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 10051.1
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
64 can be fit into 600 9 times, resulting in a remainder of 24.
The number 9 becomes the next digit in our result. 
Result so far: 10051.109
Deduct 576 from 600 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 10:
240 divided by 64 is 3 with a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 10051.1093
Deduct 192 from 240 and we're left 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.

Let's proceed to step 11:
The number 64 fits into 480 7 times, leaving a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 10051.10937
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.

Going ahead to step 12:
When dividing 320 by 64, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 10051.109375
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.

Let's proceed to step 13:
When dividing 0 by 64, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10051.109375
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.

Moving on to step 14:
When dividing 0 by 64, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 10051.109375
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.

In conclusion, the division gives 10051.109375 with a balance of 0.0.
