We're dividing 86092929 by 166 
The aim is to understand the frequency of 166 in 86092929.

Advancing to step 1:
When dividing 8 by 166, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 166

Step 2:
86 divided by 166 is 0 with a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Append the next digit (0) from the dividend to 86 and continue with: 860 / 166

Advancing to step 3:
When dividing 860 by 166, we get 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 30 after subtracting 830 from 860.
Append the next digit (9) from the dividend to 30 and continue with: 309 / 166

Going ahead to step 4:
The number 166 fits into 309 1 times, leaving a remainder of 143.
The next digit of our result is 1. 
Result so far: 51.0
If we take 166 away from 309, we end up with 143.
Bring next digit (2) of the dividend behind the 143 and repeat the process: 1432 / 166

Moving on to step 5:
166 can be fit into 1432 8 times, resulting in a remainder of 104.
The next digit of our result is 8. 
Result so far: 518.0
Subtracting 1328 from 1432 leaves us with 104.
Grab the next digit (9) from the dividend, add it to 104, then carry on: 1049 / 166

Let's proceed to step 6:
1049 divided by 166 is 6 with a remainder of 53.
Use 6 as the next digit of our solution. 
Result so far: 5186.0
Subtract 996 from 1049 to get 53.
Grab the next digit (2) from the dividend, add it to 53, then carry on: 532 / 166

Let's proceed to step 7:
When dividing 532 by 166, we get 3 with a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 51863.0
Subtracting 498 from 532 leaves us with 34.
Include the next digit (9) from the dividend after 34, then repeat: 349 / 166

Moving on to step 8:
349 divided by 166 is 2 with a remainder of 17.
The number 2 becomes the next digit in our result. 
Result so far: 518632.0
Subtracting 332 from 349 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 9:
If we divide 170 by 166, we get 1 and a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 518632.1
Subtracting 166 from 170 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.

Step 10:
166 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 518632.1
Subtracting 0 from 40 leaves us with 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 11:
If we divide 400 by 166, we get 2 and a remainder of 68.
The next digit of our result is 2. 
Result so far: 518632.102
If we subtract 332 from 400, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 12:
166 can be fit into 680 4 times, resulting in a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 518632.1024
Subtracting 664 from 680 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 13:
166 goes into 160 0 times with a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 518632.1024
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 14:
166 goes into 1600 9 times with a remainder of 106.
Write down 9 as next digit of the result. 
Result so far: 518632.102409
If we subtract 1494 from 1600, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 15:
1060 divided by 166 is 6 with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 518632.1024096
The remainder is 64 after subtracting 996 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 16:
The number 166 fits into 640 3 times, leaving a remainder of 142.
The number 3 becomes the next digit in our result. 
Result so far: 518632.10240963
Deduct 498 from 640 and we're left with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

In conclusion, the division gives 518632.10240963 with a balance of 1.42e-07.
