845309 divided by 51 
The aim is to understand the frequency of 51 in 845309.

Going ahead to step 1:
When dividing 8 by 51, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 51

Advancing to step 2:
51 goes into 84 1 times with a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 51 from 84, we get 33.
Take the next digit (5) from the dividend and append it to 33, then repeat: 335 / 51

Moving on to step 3:
51 goes into 335 6 times with a remainder of 29.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtracting 306 from 335 leaves us with 29.
Bring next digit (3) of the dividend behind the 29 and repeat the process: 293 / 51

Step 4:
51 goes into 293 5 times with a remainder of 38.
Record the quotient 5 as the next digit in the result. 
Result so far: 165.0
If we subtract 255 from 293, we get 38.
Bring next digit (0) of the dividend behind the 38 and repeat the process: 380 / 51

Advancing to step 5:
If we divide 380 by 51, we get 7 and a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 1657.0
If we take 357 away from 380, we end up with 23.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 51

Let's proceed to step 6:
If we divide 239 by 51, we get 4 and a remainder of 35.
Write down 4 as next digit of the result. 
Result so far: 16574.0
If we subtract 204 from 239, we 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.

Let's proceed to step 7:
350 divided by 51 is 6 with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 16574.6
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.

Advancing to step 8:
When dividing 440 by 51, we get 8 with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 16574.68
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.

Let's proceed to step 9:
51 goes into 320 6 times with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 16574.686
Deduct 306 from 320 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 10:
51 can be fit into 140 2 times, resulting in a remainder of 38.
The next digit of our result is 2. 
Result so far: 16574.6862
If we subtract 102 from 140, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 11:
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: 16574.68627
Subtracting 357 from 380 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 12:
230 divided by 51 is 4 with a remainder of 26.
The next digit of our result is 4. 
Result so far: 16574.686274
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.

Advancing to step 13:
The number 51 fits into 260 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 16574.6862745
If we subtract 255 from 260, we 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.

Let's proceed to step 14:
If we divide 50 by 51, we get 0 and a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 16574.6862745
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 16574.6862745 and a remainder of 5e-08.
