We're dividing 325122 by 51 
The aim is to understand the frequency of 51 in 325122.

Step 1:
When dividing 3 by 51, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 51

On to step 2:
If we divide 32 by 51, we get 0 and a remainder of 32.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 32 to get 32.
Grab the next digit (5) from the dividend, add it to 32, then carry on: 325 / 51

Let's proceed to step 3:
325 divided by 51 is 6 with a remainder of 19.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 306 from 325 and we're left with 19.
Include the next digit (1) from the dividend after 19, then repeat: 191 / 51

On to step 4:
191 divided by 51 is 3 with a remainder of 38.
Put 3 as the next digit of the answer. 
Result so far: 63.0
The remainder is 38 after subtracting 153 from 191.
Append the next digit (2) from the dividend to 38 and continue with: 382 / 51

Let's proceed to step 5:
The number 51 fits into 382 7 times, leaving a remainder of 25.
Write down 7 as next digit of the result. 
Result so far: 637.0
If we subtract 357 from 382, we get 25.
Grab the next digit (2) from the dividend, add it to 25, then carry on: 252 / 51

Moving on to step 6:
When dividing 252 by 51, we get 4 with a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 6374.0
Subtract 204 from 252 to 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.

Let's proceed to step 7:
When dividing 480 by 51, we get 9 with a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 6374.9
Subtracting 459 from 480 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 8:
210 divided by 51 is 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 6374.94
If we take 204 away from 210, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
51 can be fit into 60 1 times, resulting in a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 6374.941
Deduct 51 from 60 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 10:
The number 51 fits into 90 1 times, leaving a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 6374.9411
If we take 51 away from 90, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The final outcome is 6374.9411, with a leftover of 0.00039.
