We look at the division of 32540889 by 166 
The aim is to understand the frequency of 166 in 32540889.

Advancing to step 1:
3 divided by 166 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 166

Moving on to step 2:
When dividing 32 by 166, we get 0 with a remainder of 32.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 32, we get 32.
Bring next digit (5) of the dividend behind the 32 and repeat the process: 325 / 166

Advancing to step 3:
166 goes into 325 1 times with a remainder of 159.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 166 from 325 leaves us with 159.
Bring next digit (4) of the dividend behind the 159 and repeat the process: 1594 / 166

Step 4:
166 goes into 1594 9 times with a remainder of 100.
Use 9 as the next digit of our solution. 
Result so far: 19.0
The remainder is 100 after subtracting 1494 from 1594.
Grab the next digit (0) from the dividend, add it to 100, then carry on: 1000 / 166

Advancing to step 5:
1000 divided by 166 is 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 196.0
Subtracting 996 from 1000 leaves us with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 166

On to step 6:
166 can be fit into 48 0 times, resulting in a remainder of 48.
The next digit of our result is 0. 
Result so far: 1960.0
Deduct 0 from 48 and we're left with 48.
Grab the next digit (8) from the dividend, add it to 48, then carry on: 488 / 166

On to step 7:
488 divided by 166 is 2 with a remainder of 156.
Put 2 as the next digit of the answer. 
Result so far: 19602.0
Subtracting 332 from 488 leaves us with 156.
Bring next digit (9) of the dividend behind the 156 and repeat the process: 1569 / 166

Step 8:
If we divide 1569 by 166, we get 9 and a remainder of 75.
Write down 9 as next digit of the result. 
Result so far: 196029.0
If we subtract 1494 from 1569, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 9:
166 can be fit into 750 4 times, resulting in a remainder of 86.
Use 4 as the next digit of our solution. 
Result so far: 196029.4
The remainder is 86 after subtracting 664 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 10:
166 goes into 860 5 times with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 196029.45
Deduct 830 from 860 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
300 divided by 166 is 1 with a remainder of 134.
Use 1 as the next digit of our solution. 
Result so far: 196029.451
If we take 166 away from 300, we end up with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Going ahead to step 12:
When dividing 1340 by 166, we get 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 196029.4518
The remainder is 12 after subtracting 1328 from 1340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 13:
When dividing 120 by 166, we get 0 with a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 196029.4518
Subtract 0 from 120 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 14:
The number 166 fits into 1200 7 times, leaving a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 196029.451807
If we take 1162 away from 1200, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 15:
If we divide 380 by 166, we get 2 and a remainder of 48.
The next digit of our result is 2. 
Result so far: 196029.4518072
If we subtract 332 from 380, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 16:
166 can be fit into 480 2 times, resulting in a remainder of 148.
Use 2 as the next digit of our solution. 
Result so far: 196029.45180722
If we subtract 332 from 480, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

The final result is 196029.45180722 with a remainder of 1.48e-07.
