505294 ÷ 51 
The aim is to understand the frequency of 51 in 505294.

On to step 1:
The number 51 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 51

Step 2:
50 divided by 51 is 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 50, we get 50.
Grab the next digit (5) from the dividend, add it to 50, then carry on: 505 / 51

Let's proceed to step 3:
The number 51 fits into 505 9 times, leaving a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 459 away from 505, we end up with 46.
Grab the next digit (2) from the dividend, add it to 46, then carry on: 462 / 51

Going ahead to step 4:
51 can be fit into 462 9 times, resulting in a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
Subtracting 459 from 462 leaves us with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 51

Let's proceed to step 5:
39 divided by 51 is 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 990.0
Subtracting 0 from 39 leaves us with 39.
Fetch the next digit (4) from the dividend, attach it to 39 and continue: 394 / 51

Moving on to step 6:
51 can be fit into 394 7 times, resulting in a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 9907.0
The remainder is 37 after subtracting 357 from 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 7:
The number 51 fits into 370 7 times, leaving a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 9907.7
Subtracting 357 from 370 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 8:
When dividing 130 by 51, we get 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 9907.72
Subtracting 102 from 130 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
When dividing 280 by 51, we get 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 9907.725
Deduct 255 from 280 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 10:
250 divided by 51 is 4 with a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 9907.7254
The remainder is 46 after subtracting 204 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 11:
When dividing 460 by 51, we get 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 9907.72549
The remainder is 1 after subtracting 459 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 12:
10 divided by 51 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 9907.72549
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 13:
51 goes into 100 1 times with a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 9907.7254901
Deduct 51 from 100 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 14:
If we divide 490 by 51, we get 9 and a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 9907.72549019
If we take 459 away from 490, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The final result is 9907.72549019 with a remainder of 3.1e-08.
