817030 divided by 51 
The aim is to understand the frequency of 51 in 817030.

Advancing to step 1:
8 divided by 51 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 51

Advancing to step 2:
51 goes into 81 1 times with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 51 from 81, we get 30.
Take the next digit (7) from the dividend and append it to 30, then repeat: 307 / 51

Step 3:
307 divided by 51 is 6 with a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 16.0
The remainder is 1 after subtracting 306 from 307.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 51

Moving on to step 4:
51 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 160.0
Deduct 0 from 10 and we're left with 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 51

Moving on to step 5:
103 divided by 51 is 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 1602.0
If we take 102 away from 103, we end up with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 51

Advancing to step 6:
51 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 16020.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
51 goes into 100 1 times with a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 16020.1
If we subtract 51 from 100, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 8:
490 divided by 51 is 9 with a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 16020.19
If we subtract 459 from 490, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 9:
When dividing 310 by 51, we get 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 16020.196
Deduct 306 from 310 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
40 divided by 51 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 16020.196
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
The number 51 fits into 400 7 times, leaving a remainder of 43.
Write down 7 as next digit of the result. 
Result so far: 16020.19607
Deduct 357 from 400 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 12:
If we divide 430 by 51, we get 8 and a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 16020.196078
Subtract 408 from 430 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 13:
When dividing 220 by 51, we get 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 16020.1960784
Subtracting 204 from 220 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 14:
160 divided by 51 is 3 with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 16020.19607843
If we subtract 153 from 160, we 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.

In conclusion, the division gives 16020.19607843 with a balance of 7e-09.
