We look at the division of 77470946 by 636 
The aim is to understand the frequency of 636 in 77470946.

Advancing to step 1:
When dividing 7 by 636, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 636

Let's proceed to step 2:
If we divide 77 by 636, we get 0 and a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Bring next digit (4) of the dividend behind the 77 and repeat the process: 774 / 636

Let's proceed to step 3:
774 divided by 636 is 1 with a remainder of 138.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 636 from 774 and we're left with 138.
Take the next digit (7) from the dividend and append it to 138, then repeat: 1387 / 636

Let's proceed to step 4:
1387 divided by 636 is 2 with a remainder of 115.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 1272 away from 1387, we end up with 115.
Include the next digit (0) from the dividend after 115, then repeat: 1150 / 636

Advancing to step 5:
If we divide 1150 by 636, we get 1 and a remainder of 514.
The next digit of our result is 1. 
Result so far: 121.0
Deduct 636 from 1150 and we're left with 514.
Include the next digit (9) from the dividend after 514, then repeat: 5149 / 636

Step 6:
When dividing 5149 by 636, we get 8 with a remainder of 61.
Record the quotient 8 as the next digit in the result. 
Result so far: 1218.0
Subtracting 5088 from 5149 leaves us with 61.
Append the next digit (4) from the dividend to 61 and continue with: 614 / 636

Advancing to step 7:
636 goes into 614 0 times with a remainder of 614.
Record the quotient 0 as the next digit in the result. 
Result so far: 12180.0
Subtracting 0 from 614 leaves us with 614.
Append the next digit (6) from the dividend to 614 and continue with: 6146 / 636

On to step 8:
6146 divided by 636 is 9 with a remainder of 422.
Record the quotient 9 as the next digit in the result. 
Result so far: 121809.0
If we subtract 5724 from 6146, we get 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Let's proceed to step 9:
636 can be fit into 4220 6 times, resulting in a remainder of 404.
Use 6 as the next digit of our solution. 
Result so far: 121809.6
The remainder is 404 after subtracting 3816 from 4220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Moving on to step 10:
When dividing 4040 by 636, we get 6 with a remainder of 224.
Put 6 as the next digit of the answer. 
Result so far: 121809.66
If we subtract 3816 from 4040, we get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

The final outcome is 121809.66, with a leftover of 0.224.
