412874 ÷ 51 
The aim is to understand the frequency of 51 in 412874.

Advancing to step 1:
51 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 51

On to step 2:
If we divide 41 by 51, we get 0 and a remainder of 41.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 41 after subtracting 0 from 41.
Take the next digit (2) from the dividend and append it to 41, then repeat: 412 / 51

Going ahead to step 3:
412 divided by 51 is 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 408 from 412 and we're left with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 51

Advancing to step 4:
If we divide 48 by 51, we get 0 and a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 80.0
Deduct 0 from 48 and we're left with 48.
Grab the next digit (7) from the dividend, add it to 48, then carry on: 487 / 51

Advancing to step 5:
If we divide 487 by 51, we get 9 and a remainder of 28.
Write down 9 as next digit of the result. 
Result so far: 809.0
The remainder is 28 after subtracting 459 from 487.
Grab the next digit (4) from the dividend, add it to 28, then carry on: 284 / 51

Advancing to step 6:
When dividing 284 by 51, we get 5 with a remainder of 29.
Use 5 as the next digit of our solution. 
Result so far: 8095.0
Subtract 255 from 284 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 7:
If we divide 290 by 51, we get 5 and a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 8095.5
Subtract 255 from 290 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 8:
If we divide 350 by 51, we get 6 and a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 8095.56
Subtract 306 from 350 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 9:
When dividing 440 by 51, we get 8 with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 8095.568
Subtract 408 from 440 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 10:
The number 51 fits into 320 6 times, leaving a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 8095.5686
If we subtract 306 from 320, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 11:
The number 51 fits into 140 2 times, leaving a remainder of 38.
The next digit of our result is 2. 
Result so far: 8095.56862
If we take 102 away from 140, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 12:
The number 51 fits into 380 7 times, leaving a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 8095.568627
If we subtract 357 from 380, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 13:
If we divide 230 by 51, we get 4 and a remainder of 26.
The next digit of our result is 4. 
Result so far: 8095.5686274
Deduct 204 from 230 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 14:
When dividing 260 by 51, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 8095.56862745
Subtract 255 from 260 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 8095.56862745 with a remainder of 5e-09.
