We look at the division of 84334541 by 166 
The aim is to understand the frequency of 166 in 84334541.

Let's proceed to step 1:
If we divide 8 by 166, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 166

On to step 2:
166 goes into 84 0 times with a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Bring next digit (3) of the dividend behind the 84 and repeat the process: 843 / 166

Going ahead to step 3:
166 can be fit into 843 5 times, resulting in a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 830 from 843, we get 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 166

On to step 4:
When dividing 133 by 166, we get 0 with a remainder of 133.
The next digit of our result is 0. 
Result so far: 50.0
If we take 0 away from 133, we end up with 133.
Include the next digit (4) from the dividend after 133, then repeat: 1334 / 166

Advancing to step 5:
1334 divided by 166 is 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 508.0
Subtracting 1328 from 1334 leaves us with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 166

On to step 6:
When dividing 65 by 166, we get 0 with a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 5080.0
Deduct 0 from 65 and we're left with 65.
Include the next digit (4) from the dividend after 65, then repeat: 654 / 166

Advancing to step 7:
If we divide 654 by 166, we get 3 and a remainder of 156.
Use 3 as the next digit of our solution. 
Result so far: 50803.0
Deduct 498 from 654 and we're left with 156.
Take the next digit (1) from the dividend and append it to 156, then repeat: 1561 / 166

Advancing to step 8:
1561 divided by 166 is 9 with a remainder of 67.
The number 9 becomes the next digit in our result. 
Result so far: 508039.0
If we subtract 1494 from 1561, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 9:
When dividing 670 by 166, we get 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 508039.4
If we subtract 664 from 670, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 10:
The number 166 fits into 60 0 times, leaving a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 508039.4
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 11:
When dividing 600 by 166, we get 3 with a remainder of 102.
The next digit of our result is 3. 
Result so far: 508039.403
The remainder is 102 after subtracting 498 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Let's proceed to step 12:
166 can be fit into 1020 6 times, resulting in a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 508039.4036
If we subtract 996 from 1020, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 13:
166 can be fit into 240 1 times, resulting in a remainder of 74.
The number 1 becomes the next digit in our result. 
Result so far: 508039.40361
Subtracting 166 from 240 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 14:
When dividing 740 by 166, we get 4 with a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 508039.403614
The remainder is 76 after subtracting 664 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 15:
760 divided by 166 is 4 with a remainder of 96.
Record the quotient 4 as the next digit in the result. 
Result so far: 508039.4036144
If we subtract 664 from 760, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

The final result is 508039.4036144 with a remainder of 9.6e-07.
