Let's divide 78671 by 64
The aim is to understand the frequency of 64 in 78671.

Advancing to step 1:
7 divided by 64 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 64

Step 2:
When dividing 78 by 64, we get 1 with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 64 from 78 and we're left with 14.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 64

Let's proceed to step 3:
When dividing 146 by 64, we get 2 with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 128 from 146 to get 18.
Append the next digit (7) from the dividend to 18 and continue with: 187 / 64

Moving on to step 4:
187 divided by 64 is 2 with a remainder of 59.
Record the quotient 2 as the next digit in the result. 
Result so far: 122.0
The remainder is 59 after subtracting 128 from 187.
Append the next digit (1) from the dividend to 59 and continue with: 591 / 64

Step 5:
If we divide 591 by 64, we get 9 and a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 1229.0
The remainder is 15 after subtracting 576 from 591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 6:
If we divide 150 by 64, we get 2 and a remainder of 22.
The next digit of our result is 2. 
Result so far: 1229.2
If we take 128 away from 150, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 7:
64 can be fit into 220 3 times, resulting in a remainder of 28.
The next digit of our result is 3. 
Result so far: 1229.23
Deduct 192 from 220 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 8:
When dividing 280 by 64, we get 4 with a remainder of 24.
The next digit of our result is 4. 
Result so far: 1229.234
If we take 256 away from 280, we end up 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.

Let's proceed to step 9:
240 divided by 64 is 3 with a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 1229.2343
If we subtract 192 from 240, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 10:
When dividing 480 by 64, we get 7 with a remainder of 32.
Record the quotient 7 as the next digit in the result. 
Result so far: 1229.23437
The remainder is 32 after subtracting 448 from 480.
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 11:
If we divide 320 by 64, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 1229.234375
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.

Moving on to step 12:
If we divide 0 by 64, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1229.234375
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.

On to step 13:
64 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1229.234375
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.

After the division, we end up with 1229.234375 and a remainder of 0.0.
