Let's divide 802390 by 51
The aim is to understand the frequency of 51 in 802390.

Moving on to step 1:
51 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 51

Let's proceed to step 2:
51 can be fit into 80 1 times, resulting in a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 51 away from 80, we end up with 29.
Append the next digit (2) from the dividend to 29 and continue with: 292 / 51

Moving on to step 3:
If we divide 292 by 51, we get 5 and a remainder of 37.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 255 from 292 and we're left with 37.
Bring next digit (3) of the dividend behind the 37 and repeat the process: 373 / 51

Step 4:
The number 51 fits into 373 7 times, leaving a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 157.0
The remainder is 16 after subtracting 357 from 373.
Include the next digit (9) from the dividend after 16, then repeat: 169 / 51

Let's proceed to step 5:
If we divide 169 by 51, we get 3 and a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 1573.0
Subtracting 153 from 169 leaves us with 16.
Take the next digit (0) from the dividend and append it to 16, then repeat: 160 / 51

Let's proceed to step 6:
51 goes into 160 3 times with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 15733.0
Subtract 153 from 160 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
70 divided by 51 is 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 15733.1
The remainder is 19 after subtracting 51 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 8:
51 can be fit into 190 3 times, resulting in a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 15733.13
Subtracting 153 from 190 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 9:
51 can be fit into 370 7 times, resulting in a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 15733.137
Deduct 357 from 370 and we're left 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.

Step 10:
51 can be fit into 130 2 times, resulting in a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 15733.1372
The remainder is 28 after subtracting 102 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 11:
The number 51 fits into 280 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 15733.13725
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.

Step 12:
51 can be fit into 250 4 times, resulting in a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 15733.137254
If we subtract 204 from 250, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 13:
The number 51 fits into 460 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 15733.1372549
Deduct 459 from 460 and we're left with 1.
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 14:
51 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 15733.1372549
If we take 0 away from 10, we end up 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.

The final outcome is 15733.1372549, with a leftover of 1e-08.
