We look at the division of 83413411 by 685 
The aim is to understand the frequency of 685 in 83413411.

Advancing to step 1:
When dividing 8 by 685, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 685

Let's proceed to step 2:
685 can be fit into 83 0 times, resulting in a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 83 to get 83.
Take the next digit (4) from the dividend and append it to 83, then repeat: 834 / 685

Let's proceed to step 3:
When dividing 834 by 685, we get 1 with a remainder of 149.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 685 from 834 to get 149.
Include the next digit (1) from the dividend after 149, then repeat: 1491 / 685

On to step 4:
685 can be fit into 1491 2 times, resulting in a remainder of 121.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 1370 from 1491 to get 121.
Bring next digit (3) of the dividend behind the 121 and repeat the process: 1213 / 685

Moving on to step 5:
When dividing 1213 by 685, we get 1 with a remainder of 528.
Use 1 as the next digit of our solution. 
Result so far: 121.0
Subtracting 685 from 1213 leaves us with 528.
Grab the next digit (4) from the dividend, add it to 528, then carry on: 5284 / 685

Let's proceed to step 6:
5284 divided by 685 is 7 with a remainder of 489.
Use 7 as the next digit of our solution. 
Result so far: 1217.0
Deduct 4795 from 5284 and we're left with 489.
Bring next digit (1) of the dividend behind the 489 and repeat the process: 4891 / 685

Step 7:
When dividing 4891 by 685, we get 7 with a remainder of 96.
Use 7 as the next digit of our solution. 
Result so far: 12177.0
If we subtract 4795 from 4891, we get 96.
Include the next digit (1) from the dividend after 96, then repeat: 961 / 685

Let's proceed to step 8:
The number 685 fits into 961 1 times, leaving a remainder of 276.
Put 1 as the next digit of the answer. 
Result so far: 121771.0
The remainder is 276 after subtracting 685 from 961.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Going ahead to step 9:
2760 divided by 685 is 4 with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 121771.4
Subtract 2740 from 2760 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
The number 685 fits into 200 0 times, leaving a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 121771.4
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 11:
2000 divided by 685 is 2 with a remainder of 630.
The number 2 becomes the next digit in our result. 
Result so far: 121771.402
If we take 1370 away from 2000, we end up with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Step 12:
6300 divided by 685 is 9 with a remainder of 135.
Put 9 as the next digit of the answer. 
Result so far: 121771.4029
If we subtract 6165 from 6300, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 13:
The number 685 fits into 1350 1 times, leaving a remainder of 665.
Use 1 as the next digit of our solution. 
Result so far: 121771.40291
If we take 685 away from 1350, we end up with 665.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6650, and continue the process.

Advancing to step 14:
685 goes into 6650 9 times with a remainder of 485.
Write down 9 as next digit of the result. 
Result so far: 121771.402919
If we subtract 6165 from 6650, we get 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Step 15:
685 can be fit into 4850 7 times, resulting in a remainder of 55.
Put 7 as the next digit of the answer. 
Result so far: 121771.4029197
If we take 4795 away from 4850, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 16:
685 goes into 550 0 times with a remainder of 550.
Write down 0 as next digit of the result. 
Result so far: 121771.4029197
Deduct 0 from 550 and we're left with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

The quotient of the division is 121771.4029197, and the remainder is 5.5e-07.
