We look at the division of 51940059 by 69 
The aim is to understand the frequency of 69 in 51940059.

Let's proceed to step 1:
When dividing 5 by 69, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 69

Step 2:
The number 69 fits into 51 0 times, leaving a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Grab the next digit (9) from the dividend, add it to 51, then carry on: 519 / 69

Step 3:
The number 69 fits into 519 7 times, leaving a remainder of 36.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 483 from 519 to get 36.
Bring next digit (4) of the dividend behind the 36 and repeat the process: 364 / 69

Step 4:
When dividing 364 by 69, we get 5 with a remainder of 19.
The next digit of our result is 5. 
Result so far: 75.0
If we take 345 away from 364, we end up with 19.
Include the next digit (0) from the dividend after 19, then repeat: 190 / 69

Moving on to step 5:
The number 69 fits into 190 2 times, leaving a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 752.0
Subtracting 138 from 190 leaves us with 52.
Include the next digit (0) from the dividend after 52, then repeat: 520 / 69

Step 6:
69 goes into 520 7 times with a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 7527.0
If we take 483 away from 520, we end up with 37.
Append the next digit (5) from the dividend to 37 and continue with: 375 / 69

Advancing to step 7:
375 divided by 69 is 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 75275.0
Deduct 345 from 375 and we're left with 30.
Bring next digit (9) of the dividend behind the 30 and repeat the process: 309 / 69

Going ahead to step 8:
69 goes into 309 4 times with a remainder of 33.
Write down 4 as next digit of the result. 
Result so far: 752754.0
Deduct 276 from 309 and we're left 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.

Advancing to step 9:
When dividing 330 by 69, we get 4 with a remainder of 54.
Put 4 as the next digit of the answer. 
Result so far: 752754.4
If we subtract 276 from 330, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 10:
If we divide 540 by 69, we get 7 and a remainder of 57.
The next digit of our result is 7. 
Result so far: 752754.47
If we subtract 483 from 540, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 11:
If we divide 570 by 69, we get 8 and a remainder of 18.
The next digit of our result is 8. 
Result so far: 752754.478
If we subtract 552 from 570, we get 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 12:
180 divided by 69 is 2 with a remainder of 42.
Write down 2 as next digit of the result. 
Result so far: 752754.4782
Subtract 138 from 180 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.

Let's proceed to step 13:
420 divided by 69 is 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 752754.47826
If we subtract 414 from 420, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 14:
If we divide 60 by 69, we get 0 and a remainder of 60.
The next digit of our result is 0. 
Result so far: 752754.47826
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 15:
69 can be fit into 600 8 times, resulting in a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 752754.4782608
Subtracting 552 from 600 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 16:
When dividing 480 by 69, we get 6 with a remainder of 66.
Use 6 as the next digit of our solution. 
Result so far: 752754.47826086
Deduct 414 from 480 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Our division results in 752754.47826086 with a remaining 6.6e-08.
