We look at the division of 379130 by 51 
The aim is to understand the frequency of 51 in 379130.

On to step 1:
51 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 51

Let's proceed to step 2:
When dividing 37 by 51, we get 0 with a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Append the next digit (9) from the dividend to 37 and continue with: 379 / 51

On to step 3:
51 goes into 379 7 times with a remainder of 22.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 22 after subtracting 357 from 379.
Fetch the next digit (1) from the dividend, attach it to 22 and continue: 221 / 51

Step 4:
51 can be fit into 221 4 times, resulting in a remainder of 17.
Put 4 as the next digit of the answer. 
Result so far: 74.0
Subtracting 204 from 221 leaves us with 17.
Include the next digit (3) from the dividend after 17, then repeat: 173 / 51

Advancing to step 5:
173 divided by 51 is 3 with a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 743.0
If we take 153 away from 173, we end up with 20.
Take the next digit (0) from the dividend and append it to 20, then repeat: 200 / 51

Advancing to step 6:
The number 51 fits into 200 3 times, leaving a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 7433.0
If we take 153 away from 200, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 7:
51 can be fit into 470 9 times, resulting in a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 7433.9
If we take 459 away from 470, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 8:
51 goes into 110 2 times with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 7433.92
The remainder is 8 after subtracting 102 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
If we divide 80 by 51, we get 1 and a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 7433.921
Subtracting 51 from 80 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 10:
When dividing 290 by 51, we get 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 7433.9215
If we subtract 255 from 290, 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.

Step 11:
The number 51 fits into 350 6 times, leaving a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 7433.92156
If we take 306 away from 350, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 12:
440 divided by 51 is 8 with a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 7433.921568
Subtracting 408 from 440 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 13:
The number 51 fits into 320 6 times, leaving a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 7433.9215686
Subtracting 306 from 320 leaves us 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 14:
When dividing 140 by 51, we get 2 with a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 7433.92156862
Subtracting 102 from 140 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The quotient of the division is 7433.92156862, and the remainder is 3.8e-08.
