We look at the division of 30038193 by 51 
The aim is to understand the frequency of 51 in 30038193.

Step 1:
51 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 51

Advancing to step 2:
If we divide 30 by 51, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Take the next digit (0) from the dividend and append it to 30, then repeat: 300 / 51

On to step 3:
300 divided by 51 is 5 with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 45 after subtracting 255 from 300.
Bring next digit (3) of the dividend behind the 45 and repeat the process: 453 / 51

Moving on to step 4:
51 can be fit into 453 8 times, resulting in a remainder of 45.
The number 8 becomes the next digit in our result. 
Result so far: 58.0
If we subtract 408 from 453, we get 45.
Grab the next digit (8) from the dividend, add it to 45, then carry on: 458 / 51

Moving on to step 5:
When dividing 458 by 51, we get 8 with a remainder of 50.
Record the quotient 8 as the next digit in the result. 
Result so far: 588.0
Subtracting 408 from 458 leaves us with 50.
Include the next digit (1) from the dividend after 50, then repeat: 501 / 51

Advancing to step 6:
If we divide 501 by 51, we get 9 and a remainder of 42.
The next digit of our result is 9. 
Result so far: 5889.0
Subtract 459 from 501 to get 42.
Grab the next digit (9) from the dividend, add it to 42, then carry on: 429 / 51

On to step 7:
51 can be fit into 429 8 times, resulting in a remainder of 21.
Use 8 as the next digit of our solution. 
Result so far: 58898.0
If we subtract 408 from 429, we get 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 51

On to step 8:
51 goes into 213 4 times with a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 588984.0
Subtracting 204 from 213 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 9:
The number 51 fits into 90 1 times, leaving a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 588984.1
If we take 51 away from 90, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 10:
The number 51 fits into 390 7 times, leaving a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 588984.17
The remainder is 33 after subtracting 357 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 11:
51 goes into 330 6 times with a remainder of 24.
The next digit of our result is 6. 
Result so far: 588984.176
Subtract 306 from 330 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
240 divided by 51 is 4 with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 588984.1764
Deduct 204 from 240 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 13:
The number 51 fits into 360 7 times, leaving a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 588984.17647
Subtract 357 from 360 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 14:
The number 51 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 588984.17647
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 15:
51 can be fit into 300 5 times, resulting in a remainder of 45.
The next digit of our result is 5. 
Result so far: 588984.1764705
If we subtract 255 from 300, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 16:
If we divide 450 by 51, we get 8 and a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 588984.17647058
Subtracting 408 from 450 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

In conclusion, the division gives 588984.17647058 with a balance of 4.2e-08.
