We're dividing 166692 by 51 
The aim is to understand the frequency of 51 in 166692.

Going ahead to step 1:
The number 51 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 51

Step 2:
When dividing 16 by 51, we get 0 with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Fetch the next digit (6) from the dividend, attach it to 16 and continue: 166 / 51

Let's proceed to step 3:
51 can be fit into 166 3 times, resulting in a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 13 after subtracting 153 from 166.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 51

Step 4:
51 goes into 136 2 times with a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 32.0
Deduct 102 from 136 and we're left with 34.
Include the next digit (9) from the dividend after 34, then repeat: 349 / 51

Moving on to step 5:
51 can be fit into 349 6 times, resulting in a remainder of 43.
Record the quotient 6 as the next digit in the result. 
Result so far: 326.0
Subtract 306 from 349 to get 43.
Grab the next digit (2) from the dividend, add it to 43, then carry on: 432 / 51

Let's proceed to step 6:
When dividing 432 by 51, we get 8 with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 3268.0
Subtracting 408 from 432 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 7:
The number 51 fits into 240 4 times, leaving a remainder of 36.
The next digit of our result is 4. 
Result so far: 3268.4
If we subtract 204 from 240, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 8:
360 divided by 51 is 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 3268.47
Subtract 357 from 360 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
51 goes into 30 0 times with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 3268.47
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
51 can be fit into 300 5 times, resulting in a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 3268.4705
If we subtract 255 from 300, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 11:
450 divided by 51 is 8 with a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 3268.47058
Deduct 408 from 450 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 12:
When dividing 420 by 51, we get 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 3268.470588
Subtracting 408 from 420 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 3268.470588, and the remainder is 1.2e-06.
