909999 divided by 69 
The aim is to understand the frequency of 69 in 909999.

Going ahead to step 1:
If we divide 9 by 69, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 69

Moving on to step 2:
When dividing 90 by 69, we get 1 with a remainder of 21.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 69 from 90, we get 21.
Include the next digit (9) from the dividend after 21, then repeat: 219 / 69

Moving on to step 3:
69 goes into 219 3 times with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 207 from 219, we get 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 69

Going ahead to step 4:
If we divide 129 by 69, we get 1 and a remainder of 60.
Record the quotient 1 as the next digit in the result. 
Result so far: 131.0
Deduct 69 from 129 and we're left with 60.
Fetch the next digit (9) from the dividend, attach it to 60 and continue: 609 / 69

Going ahead to step 5:
609 divided by 69 is 8 with a remainder of 57.
Put 8 as the next digit of the answer. 
Result so far: 1318.0
Deduct 552 from 609 and we're left with 57.
Bring next digit (9) of the dividend behind the 57 and repeat the process: 579 / 69

Let's proceed to step 6:
69 goes into 579 8 times with a remainder of 27.
The number 8 becomes the next digit in our result. 
Result so far: 13188.0
Deduct 552 from 579 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 7:
69 can be fit into 270 3 times, resulting in a remainder of 63.
Record the quotient 3 as the next digit in the result. 
Result so far: 13188.3
The remainder is 63 after subtracting 207 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 8:
630 divided by 69 is 9 with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 13188.39
Subtract 621 from 630 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.

Going ahead to step 9:
69 goes into 90 1 times with a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 13188.391
Subtracting 69 from 90 leaves us 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.

Advancing to step 10:
210 divided by 69 is 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 13188.3913
If we take 207 away from 210, 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.

Moving on to step 11:
If we divide 30 by 69, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 13188.3913
If we take 0 away from 30, we end up 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.

Step 12:
69 goes into 300 4 times with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 13188.391304
If we take 276 away from 300, we end up 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.

Moving on to step 13:
The number 69 fits into 240 3 times, leaving a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 13188.3913043
Subtract 207 from 240 to get 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 14:
If we divide 330 by 69, we get 4 and a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 13188.39130434
Deduct 276 from 330 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

In conclusion, the division gives 13188.39130434 with a balance of 5.4e-08.
