We look at the division of 52116178 by 669 
The aim is to understand the frequency of 669 in 52116178.

Advancing to step 1:
When dividing 5 by 669, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 669

Step 2:
If we divide 52 by 669, we get 0 and a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Include the next digit (1) from the dividend after 52, then repeat: 521 / 669

Moving on to step 3:
669 can be fit into 521 0 times, resulting in a remainder of 521.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 521 and we're left with 521.
Fetch the next digit (1) from the dividend, attach it to 521 and continue: 5211 / 669

Moving on to step 4:
5211 divided by 669 is 7 with a remainder of 528.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 4683 from 5211 and we're left with 528.
Append the next digit (6) from the dividend to 528 and continue with: 5286 / 669

Going ahead to step 5:
5286 divided by 669 is 7 with a remainder of 603.
The number 7 becomes the next digit in our result. 
Result so far: 77.0
Subtracting 4683 from 5286 leaves us with 603.
Take the next digit (1) from the dividend and append it to 603, then repeat: 6031 / 669

Moving on to step 6:
6031 divided by 669 is 9 with a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 779.0
If we take 6021 away from 6031, we end up with 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 669

Going ahead to step 7:
669 goes into 107 0 times with a remainder of 107.
Record the quotient 0 as the next digit in the result. 
Result so far: 7790.0
Subtract 0 from 107 to get 107.
Fetch the next digit (8) from the dividend, attach it to 107 and continue: 1078 / 669

Going ahead to step 8:
When dividing 1078 by 669, we get 1 with a remainder of 409.
Put 1 as the next digit of the answer. 
Result so far: 77901.0
If we subtract 669 from 1078, we get 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Moving on to step 9:
4090 divided by 669 is 6 with a remainder of 76.
Record the quotient 6 as the next digit in the result. 
Result so far: 77901.6
Subtract 4014 from 4090 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 10:
760 divided by 669 is 1 with a remainder of 91.
Put 1 as the next digit of the answer. 
Result so far: 77901.61
Subtract 669 from 760 to get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Let's proceed to step 11:
669 goes into 910 1 times with a remainder of 241.
Write down 1 as next digit of the result. 
Result so far: 77901.611
The remainder is 241 after subtracting 669 from 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

In conclusion, the division gives 77901.611 with a balance of 0.0241.
