We look at the division of 90691369 by 685 
The aim is to understand the frequency of 685 in 90691369.

Advancing to step 1:
The number 685 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 685

Let's proceed to step 2:
90 divided by 685 is 0 with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Bring next digit (6) of the dividend behind the 90 and repeat the process: 906 / 685

Going ahead to step 3:
When dividing 906 by 685, we get 1 with a remainder of 221.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 685 from 906, we get 221.
Take the next digit (9) from the dividend and append it to 221, then repeat: 2219 / 685

Step 4:
The number 685 fits into 2219 3 times, leaving a remainder of 164.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we take 2055 away from 2219, we end up with 164.
Take the next digit (1) from the dividend and append it to 164, then repeat: 1641 / 685

Going ahead to step 5:
685 goes into 1641 2 times with a remainder of 271.
Write down 2 as next digit of the result. 
Result so far: 132.0
Subtract 1370 from 1641 to get 271.
Take the next digit (3) from the dividend and append it to 271, then repeat: 2713 / 685

Going ahead to step 6:
685 goes into 2713 3 times with a remainder of 658.
Put 3 as the next digit of the answer. 
Result so far: 1323.0
If we subtract 2055 from 2713, we get 658.
Take the next digit (6) from the dividend and append it to 658, then repeat: 6586 / 685

Step 7:
685 goes into 6586 9 times with a remainder of 421.
The number 9 becomes the next digit in our result. 
Result so far: 13239.0
If we take 6165 away from 6586, we end up with 421.
Bring next digit (9) of the dividend behind the 421 and repeat the process: 4219 / 685

Moving on to step 8:
685 goes into 4219 6 times with a remainder of 109.
The number 6 becomes the next digit in our result. 
Result so far: 132396.0
If we take 4110 away from 4219, we end up with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Let's proceed to step 9:
1090 divided by 685 is 1 with a remainder of 405.
Write down 1 as next digit of the result. 
Result so far: 132396.1
Subtract 685 from 1090 to get 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Moving on to step 10:
685 can be fit into 4050 5 times, resulting in a remainder of 625.
The next digit of our result is 5. 
Result so far: 132396.15
If we take 3425 away from 4050, we end up with 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Going ahead to step 11:
When dividing 6250 by 685, we get 9 with a remainder of 85.
Put 9 as the next digit of the answer. 
Result so far: 132396.159
Subtracting 6165 from 6250 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 12:
The number 685 fits into 850 1 times, leaving a remainder of 165.
The number 1 becomes the next digit in our result. 
Result so far: 132396.1591
Subtracting 685 from 850 leaves us with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Going ahead to step 13:
If we divide 1650 by 685, we get 2 and a remainder of 280.
Use 2 as the next digit of our solution. 
Result so far: 132396.15912
Subtracting 1370 from 1650 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 14:
2800 divided by 685 is 4 with a remainder of 60.
Write down 4 as next digit of the result. 
Result so far: 132396.159124
If we take 2740 away from 2800, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 15:
600 divided by 685 is 0 with a remainder of 600.
Put 0 as the next digit of the answer. 
Result so far: 132396.159124
Subtracting 0 from 600 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Advancing to step 16:
If we divide 6000 by 685, we get 8 and a remainder of 520.
Use 8 as the next digit of our solution. 
Result so far: 132396.15912408
The remainder is 520 after subtracting 5480 from 6000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

In conclusion, the division gives 132396.15912408 with a balance of 5.2e-07.
