We're dividing 69912490 by 909 
The aim is to understand the frequency of 909 in 69912490.

Going ahead to step 1:
909 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 909

Moving on to step 2:
909 can be fit into 69 0 times, resulting in a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 69 to get 69.
Include the next digit (9) from the dividend after 69, then repeat: 699 / 909

Step 3:
699 divided by 909 is 0 with a remainder of 699.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 699 leaves us with 699.
Bring next digit (1) of the dividend behind the 699 and repeat the process: 6991 / 909

On to step 4:
When dividing 6991 by 909, we get 7 with a remainder of 628.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 6363 from 6991, we get 628.
Include the next digit (2) from the dividend after 628, then repeat: 6282 / 909

Advancing to step 5:
6282 divided by 909 is 6 with a remainder of 828.
Put 6 as the next digit of the answer. 
Result so far: 76.0
Subtracting 5454 from 6282 leaves us with 828.
Include the next digit (4) from the dividend after 828, then repeat: 8284 / 909

Advancing to step 6:
8284 divided by 909 is 9 with a remainder of 103.
The next digit of our result is 9. 
Result so far: 769.0
Deduct 8181 from 8284 and we're left with 103.
Bring next digit (9) of the dividend behind the 103 and repeat the process: 1039 / 909

On to step 7:
The number 909 fits into 1039 1 times, leaving a remainder of 130.
Write down 1 as next digit of the result. 
Result so far: 7691.0
The remainder is 130 after subtracting 909 from 1039.
Grab the next digit (0) from the dividend, add it to 130, then carry on: 1300 / 909

Step 8:
1300 divided by 909 is 1 with a remainder of 391.
The number 1 becomes the next digit in our result. 
Result so far: 76911.0
Deduct 909 from 1300 and we're left with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Going ahead to step 9:
If we divide 3910 by 909, we get 4 and a remainder of 274.
Write down 4 as next digit of the result. 
Result so far: 76911.4
If we subtract 3636 from 3910, we get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Step 10:
2740 divided by 909 is 3 with a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 76911.43
Subtracting 2727 from 2740 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 11:
909 can be fit into 130 0 times, resulting in a remainder of 130.
Write down 0 as next digit of the result. 
Result so far: 76911.43
If we take 0 away from 130, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 12:
909 can be fit into 1300 1 times, resulting in a remainder of 391.
The number 1 becomes the next digit in our result. 
Result so far: 76911.4301
If we subtract 909 from 1300, we get 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Moving on to step 13:
3910 divided by 909 is 4 with a remainder of 274.
The next digit of our result is 4. 
Result so far: 76911.43014
The remainder is 274 after subtracting 3636 from 3910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

On to step 14:
When dividing 2740 by 909, we get 3 with a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 76911.430143
Subtract 2727 from 2740 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 15:
909 can be fit into 130 0 times, resulting in a remainder of 130.
Put 0 as the next digit of the answer. 
Result so far: 76911.430143
The remainder is 130 after subtracting 0 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 16:
1300 divided by 909 is 1 with a remainder of 391.
Write down 1 as next digit of the result. 
Result so far: 76911.43014301
Subtracting 909 from 1300 leaves us with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

The final outcome is 76911.43014301, with a leftover of 3.91e-07.
