Let's divide 66201 by 51
The aim is to understand the frequency of 51 in 66201.

Step 1:
51 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 51

Moving on to step 2:
66 divided by 51 is 1 with a remainder of 15.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 15 after subtracting 51 from 66.
Grab the next digit (2) from the dividend, add it to 15, then carry on: 152 / 51

Advancing to step 3:
When dividing 152 by 51, we get 2 with a remainder of 50.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 102 from 152 to get 50.
Append the next digit (0) from the dividend to 50 and continue with: 500 / 51

On to step 4:
When dividing 500 by 51, we get 9 with a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 129.0
Subtract 459 from 500 to get 41.
Fetch the next digit (1) from the dividend, attach it to 41 and continue: 411 / 51

Let's proceed to step 5:
If we divide 411 by 51, we get 8 and a remainder of 3.
The next digit of our result is 8. 
Result so far: 1298.0
Deduct 408 from 411 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 6:
51 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 1298.0
Subtracting 0 from 30 leaves us 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.

Going ahead to step 7:
300 divided by 51 is 5 with a remainder of 45.
The next digit of our result is 5. 
Result so far: 1298.05
If we take 255 away from 300, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 8:
51 goes into 450 8 times with a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 1298.058
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.

Let's proceed to step 9:
51 goes into 420 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 1298.0588
If we subtract 408 from 420, we get 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 final outcome is 1298.0588, with a leftover of 0.00012.
