Let's divide 97669785 by 51
The aim is to understand the frequency of 51 in 97669785.

Advancing to step 1:
If we divide 9 by 51, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 51

Going ahead to step 2:
When dividing 97 by 51, we get 1 with a remainder of 46.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 51 from 97, we get 46.
Include the next digit (6) from the dividend after 46, then repeat: 466 / 51

Going ahead to step 3:
466 divided by 51 is 9 with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
The remainder is 7 after subtracting 459 from 466.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 51

Advancing to step 4:
The number 51 fits into 76 1 times, leaving a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 191.0
The remainder is 25 after subtracting 51 from 76.
Take the next digit (9) from the dividend and append it to 25, then repeat: 259 / 51

Let's proceed to step 5:
If we divide 259 by 51, we get 5 and a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 1915.0
Deduct 255 from 259 and we're left with 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 51

Moving on to step 6:
47 divided by 51 is 0 with a remainder of 47.
The number 0 becomes the next digit in our result. 
Result so far: 19150.0
If we take 0 away from 47, we end up with 47.
Fetch the next digit (8) from the dividend, attach it to 47 and continue: 478 / 51

On to step 7:
51 can be fit into 478 9 times, resulting in a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 191509.0
Deduct 459 from 478 and we're left with 19.
Include the next digit (5) from the dividend after 19, then repeat: 195 / 51

Going ahead to step 8:
If we divide 195 by 51, we get 3 and a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 1915093.0
Deduct 153 from 195 and we're left 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.

Let's proceed to step 9:
420 divided by 51 is 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 1915093.8
Deduct 408 from 420 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 10:
If we divide 120 by 51, we get 2 and a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 1915093.82
If we take 102 away from 120, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 11:
180 divided by 51 is 3 with a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 1915093.823
Subtract 153 from 180 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 12:
If we divide 270 by 51, we get 5 and a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 1915093.8235
Subtract 255 from 270 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 13:
150 divided by 51 is 2 with a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 1915093.82352
If we subtract 102 from 150, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 14:
When dividing 480 by 51, we get 9 with a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 1915093.823529
Deduct 459 from 480 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 15:
When dividing 210 by 51, we get 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 1915093.8235294
Subtracting 204 from 210 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 16:
51 can be fit into 60 1 times, resulting in a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1915093.82352941
Subtracting 51 from 60 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.

The final outcome is 1915093.82352941, with a leftover of 9e-09.
