We look at the division of 20153401 by 64 
The aim is to understand the frequency of 64 in 20153401.

Let's proceed to step 1:
If we divide 2 by 64, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 64

Moving on to step 2:
If we divide 20 by 64, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Take the next digit (1) from the dividend and append it to 20, then repeat: 201 / 64

Advancing to step 3:
When dividing 201 by 64, we get 3 with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 192 from 201 to get 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 64

Moving on to step 4:
When dividing 95 by 64, we get 1 with a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 31.0
Deduct 64 from 95 and we're left with 31.
Grab the next digit (3) from the dividend, add it to 31, then carry on: 313 / 64

On to step 5:
64 can be fit into 313 4 times, resulting in a remainder of 57.
The number 4 becomes the next digit in our result. 
Result so far: 314.0
If we subtract 256 from 313, we get 57.
Take the next digit (4) from the dividend and append it to 57, then repeat: 574 / 64

Moving on to step 6:
The number 64 fits into 574 8 times, leaving a remainder of 62.
The number 8 becomes the next digit in our result. 
Result so far: 3148.0
Subtracting 512 from 574 leaves us with 62.
Include the next digit (0) from the dividend after 62, then repeat: 620 / 64

Advancing to step 7:
When dividing 620 by 64, we get 9 with a remainder of 44.
Record the quotient 9 as the next digit in the result. 
Result so far: 31489.0
The remainder is 44 after subtracting 576 from 620.
Append the next digit (1) from the dividend to 44 and continue with: 441 / 64

Let's proceed to step 8:
64 goes into 441 6 times with a remainder of 57.
Put 6 as the next digit of the answer. 
Result so far: 314896.0
Subtracting 384 from 441 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 9:
64 can be fit into 570 8 times, resulting in a remainder of 58.
The number 8 becomes the next digit in our result. 
Result so far: 314896.8
If we subtract 512 from 570, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 10:
64 can be fit into 580 9 times, resulting in a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 314896.89
Subtracting 576 from 580 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
When dividing 40 by 64, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 314896.89
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
If we divide 400 by 64, we get 6 and a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 314896.8906
The remainder is 16 after subtracting 384 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
If we divide 160 by 64, we get 2 and a remainder of 32.
The next digit of our result is 2. 
Result so far: 314896.89062
Subtracting 128 from 160 leaves us 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 14:
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: 314896.890625
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.

Moving 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: 314896.890625
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.

Let's proceed to step 16:
When dividing 0 by 64, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 314896.890625
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 314896.890625, with a leftover of 0.0.
