43480206 divided by 64 
The aim is to understand the frequency of 64 in 43480206.

On to step 1:
When dividing 4 by 64, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 64

Advancing to step 2:
When dividing 43 by 64, we get 0 with a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Take the next digit (4) from the dividend and append it to 43, then repeat: 434 / 64

Moving on to step 3:
64 goes into 434 6 times with a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 50 after subtracting 384 from 434.
Take the next digit (8) from the dividend and append it to 50, then repeat: 508 / 64

Moving on to step 4:
When dividing 508 by 64, we get 7 with a remainder of 60.
The next digit of our result is 7. 
Result so far: 67.0
Subtracting 448 from 508 leaves us with 60.
Grab the next digit (0) from the dividend, add it to 60, then carry on: 600 / 64

Moving on to step 5:
The number 64 fits into 600 9 times, leaving a remainder of 24.
Write down 9 as next digit of the result. 
Result so far: 679.0
Subtracting 576 from 600 leaves us with 24.
Take the next digit (2) from the dividend and append it to 24, then repeat: 242 / 64

Step 6:
64 goes into 242 3 times with a remainder of 50.
Use 3 as the next digit of our solution. 
Result so far: 6793.0
Deduct 192 from 242 and we're left with 50.
Append the next digit (0) from the dividend to 50 and continue with: 500 / 64

On to step 7:
When dividing 500 by 64, we get 7 with a remainder of 52.
Record the quotient 7 as the next digit in the result. 
Result so far: 67937.0
The remainder is 52 after subtracting 448 from 500.
Include the next digit (6) from the dividend after 52, then repeat: 526 / 64

On to step 8:
64 can be fit into 526 8 times, resulting in a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 679378.0
If we subtract 512 from 526, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
If we divide 140 by 64, we get 2 and a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 679378.2
Subtracting 128 from 140 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 10:
The number 64 fits into 120 1 times, leaving a remainder of 56.
The number 1 becomes the next digit in our result. 
Result so far: 679378.21
Subtract 64 from 120 to 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.

On to step 11:
560 divided by 64 is 8 with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 679378.218
Subtract 512 from 560 to 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.

Advancing to step 12:
64 goes into 480 7 times with a remainder of 32.
Write down 7 as next digit of the result. 
Result so far: 679378.2187
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.

Step 13:
320 divided by 64 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 679378.21875
The remainder is 0 after subtracting 320 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 14:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 679378.21875
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 15:
If we divide 0 by 64, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 679378.21875
Subtracting 0 from 0 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.

The final outcome is 679378.21875, with a leftover of 0.0.
