We look at the division of 9677909 by 51 
The aim is to understand the frequency of 51 in 9677909.

Let's proceed to step 1:
If we divide 9 by 51, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 51

Moving on to step 2:
51 can be fit into 96 1 times, resulting in a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 51 from 96 and we're left with 45.
Append the next digit (7) from the dividend to 45 and continue with: 457 / 51

Moving on to step 3:
51 can be fit into 457 8 times, resulting in a remainder of 49.
The next digit of our result is 8. 
Result so far: 18.0
If we take 408 away from 457, we end up with 49.
Grab the next digit (7) from the dividend, add it to 49, then carry on: 497 / 51

Going ahead to step 4:
If we divide 497 by 51, we get 9 and a remainder of 38.
Put 9 as the next digit of the answer. 
Result so far: 189.0
If we subtract 459 from 497, we get 38.
Bring next digit (9) of the dividend behind the 38 and repeat the process: 389 / 51

Moving on to step 5:
389 divided by 51 is 7 with a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 1897.0
Subtract 357 from 389 to get 32.
Grab the next digit (0) from the dividend, add it to 32, then carry on: 320 / 51

Let's proceed to step 6:
When dividing 320 by 51, we get 6 with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 18976.0
Deduct 306 from 320 and we're left with 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 51

Step 7:
149 divided by 51 is 2 with a remainder of 47.
Write down 2 as next digit of the result. 
Result so far: 189762.0
If we take 102 away from 149, 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.

Moving on to step 8:
When dividing 470 by 51, we get 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 189762.9
Subtracting 459 from 470 leaves us 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.

Step 9:
If we divide 110 by 51, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 189762.92
If we subtract 102 from 110, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
80 divided by 51 is 1 with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 189762.921
Subtract 51 from 80 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 11:
51 can be fit into 290 5 times, resulting in a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 189762.9215
Subtracting 255 from 290 leaves us with 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 12:
51 can be fit into 350 6 times, resulting in a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 189762.92156
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.

Step 13:
51 goes into 440 8 times with a remainder of 32.
The next digit of our result is 8. 
Result so far: 189762.921568
Deduct 408 from 440 and we're left 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.

Going ahead to step 14:
320 divided by 51 is 6 with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 189762.9215686
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 15:
140 divided by 51 is 2 with a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 189762.92156862
Deduct 102 from 140 and we're left 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.

After the division, we end up with 189762.92156862 and a remainder of 3.8e-08.
