We look at the division of 64643101 by 36 
The aim is to understand the frequency of 36 in 64643101.

Going ahead to step 1:
The number 36 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
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 / 36

On to step 2:
36 can be fit into 64 1 times, resulting in a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 36 away from 64, we end up with 28.
Take the next digit (6) from the dividend and append it to 28, then repeat: 286 / 36

Let's proceed to step 3:
The number 36 fits into 286 7 times, leaving a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 17.0
The remainder is 34 after subtracting 252 from 286.
Bring next digit (4) of the dividend behind the 34 and repeat the process: 344 / 36

Let's proceed to step 4:
36 can be fit into 344 9 times, resulting in a remainder of 20.
Use 9 as the next digit of our solution. 
Result so far: 179.0
If we take 324 away from 344, we end up with 20.
Append the next digit (3) from the dividend to 20 and continue with: 203 / 36

Advancing to step 5:
36 goes into 203 5 times with a remainder of 23.
Record the quotient 5 as the next digit in the result. 
Result so far: 1795.0
If we take 180 away from 203, we end up with 23.
Take the next digit (1) from the dividend and append it to 23, then repeat: 231 / 36

Step 6:
The number 36 fits into 231 6 times, leaving a remainder of 15.
Write down 6 as next digit of the result. 
Result so far: 17956.0
Subtracting 216 from 231 leaves us with 15.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 36

Let's proceed to step 7:
36 goes into 150 4 times with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 179564.0
Subtracting 144 from 150 leaves us with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 36

Moving on to step 8:
36 goes into 61 1 times with a remainder of 25.
Use 1 as the next digit of our solution. 
Result so far: 1795641.0
Subtract 36 from 61 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 9:
If we divide 250 by 36, we get 6 and a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 1795641.6
The remainder is 34 after subtracting 216 from 250.
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 10:
340 divided by 36 is 9 with a remainder of 16.
Record the quotient 9 as the next digit in the result. 
Result so far: 1795641.69
Subtracting 324 from 340 leaves us 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.

Let's proceed to step 11:
If we divide 160 by 36, we get 4 and a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 1795641.694
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 12:
36 can be fit into 160 4 times, resulting in a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 1795641.6944
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 1795641.6944 and a remainder of 0.00016.
