We're dividing 432380 by 51 
The aim is to understand the frequency of 51 in 432380.

Going ahead to step 1:
51 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 51

Moving on to step 2:
51 goes into 43 0 times with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Append the next digit (2) from the dividend to 43 and continue with: 432 / 51

Step 3:
51 can be fit into 432 8 times, resulting in a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 408 from 432 and we're left with 24.
Fetch the next digit (3) from the dividend, attach it to 24 and continue: 243 / 51

Let's proceed to step 4:
51 can be fit into 243 4 times, resulting in a remainder of 39.
Use 4 as the next digit of our solution. 
Result so far: 84.0
Deduct 204 from 243 and we're left with 39.
Bring next digit (8) of the dividend behind the 39 and repeat the process: 398 / 51

Going ahead to step 5:
If we divide 398 by 51, we get 7 and a remainder of 41.
The number 7 becomes the next digit in our result. 
Result so far: 847.0
If we take 357 away from 398, we end up with 41.
Grab the next digit (0) from the dividend, add it to 41, then carry on: 410 / 51

Let's proceed to step 6:
51 can be fit into 410 8 times, resulting in a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 8478.0
Subtracting 408 from 410 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
20 divided by 51 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 8478.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
200 divided by 51 is 3 with a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 8478.03
Subtract 153 from 200 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 9:
470 divided by 51 is 9 with a remainder of 11.
The next digit of our result is 9. 
Result so far: 8478.039
Deduct 459 from 470 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 10:
If we divide 110 by 51, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 8478.0392
If we take 102 away from 110, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
If we divide 80 by 51, we get 1 and a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 8478.03921
Deduct 51 from 80 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 12:
51 goes into 290 5 times with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 8478.039215
Subtracting 255 from 290 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 13:
51 goes into 350 6 times with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 8478.0392156
The remainder is 44 after subtracting 306 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 14:
The number 51 fits into 440 8 times, leaving a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 8478.03921568
The remainder is 32 after subtracting 408 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 8478.03921568 with a remainder of 3.2e-08.
