69050949 divided by 51 
The aim is to understand the frequency of 51 in 69050949.

Advancing to step 1:
6 divided by 51 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 51

Step 2:
The number 51 fits into 69 1 times, leaving a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 51 from 69 to get 18.
Take the next digit (0) from the dividend and append it to 18, then repeat: 180 / 51

Moving on to step 3:
180 divided by 51 is 3 with a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 153 from 180 leaves us with 27.
Include the next digit (5) from the dividend after 27, then repeat: 275 / 51

Moving on to step 4:
51 goes into 275 5 times with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 135.0
Subtracting 255 from 275 leaves us with 20.
Grab the next digit (0) from the dividend, add it to 20, then carry on: 200 / 51

Let's proceed to step 5:
51 goes into 200 3 times with a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 1353.0
Deduct 153 from 200 and we're left with 47.
Take the next digit (9) from the dividend and append it to 47, then repeat: 479 / 51

Moving on to step 6:
When dividing 479 by 51, we get 9 with a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 13539.0
Deduct 459 from 479 and we're left with 20.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 51

Moving on to step 7:
51 can be fit into 204 4 times, resulting in a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 135394.0
If we take 204 away from 204, we end up with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 51

Let's proceed to step 8:
51 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 1353940.0
Subtract 0 from 9 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 9:
90 divided by 51 is 1 with a remainder of 39.
The next digit of our result is 1. 
Result so far: 1353940.1
If we subtract 51 from 90, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 10:
51 goes into 390 7 times with a remainder of 33.
Use 7 as the next digit of our solution. 
Result so far: 1353940.17
If we take 357 away from 390, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 11:
If we divide 330 by 51, we get 6 and a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 1353940.176
Deduct 306 from 330 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 12:
If we divide 240 by 51, we get 4 and a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 1353940.1764
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.

Advancing to step 13:
51 goes into 360 7 times with a remainder of 3.
The next digit of our result is 7. 
Result so far: 1353940.17647
If we take 357 away from 360, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 14:
51 goes into 30 0 times with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 1353940.17647
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 15:
51 can be fit into 300 5 times, resulting in a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 1353940.1764705
The remainder is 45 after subtracting 255 from 300.
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:
51 goes into 450 8 times with a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 1353940.17647058
Subtract 408 from 450 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final outcome is 1353940.17647058, with a leftover of 4.2e-08.
