We look at the division of 18847038 by 685 
The aim is to understand the frequency of 685 in 18847038.

Going ahead to step 1:
685 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 685

Advancing to step 2:
685 can be fit into 18 0 times, resulting in a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 685

Step 3:
188 divided by 685 is 0 with a remainder of 188.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 188 after subtracting 0 from 188.
Include the next digit (4) from the dividend after 188, then repeat: 1884 / 685

Let's proceed to step 4:
685 can be fit into 1884 2 times, resulting in a remainder of 514.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 1370 from 1884 to get 514.
Bring next digit (7) of the dividend behind the 514 and repeat the process: 5147 / 685

Advancing to step 5:
When dividing 5147 by 685, we get 7 with a remainder of 352.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
If we take 4795 away from 5147, we end up with 352.
Grab the next digit (0) from the dividend, add it to 352, then carry on: 3520 / 685

Advancing to step 6:
The number 685 fits into 3520 5 times, leaving a remainder of 95.
Put 5 as the next digit of the answer. 
Result so far: 275.0
Deduct 3425 from 3520 and we're left with 95.
Take the next digit (3) from the dividend and append it to 95, then repeat: 953 / 685

Moving on to step 7:
953 divided by 685 is 1 with a remainder of 268.
Use 1 as the next digit of our solution. 
Result so far: 2751.0
Subtracting 685 from 953 leaves us with 268.
Fetch the next digit (8) from the dividend, attach it to 268 and continue: 2688 / 685

Step 8:
When dividing 2688 by 685, we get 3 with a remainder of 633.
Use 3 as the next digit of our solution. 
Result so far: 27513.0
Subtracting 2055 from 2688 leaves us with 633.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6330, and continue the process.

On to step 9:
685 can be fit into 6330 9 times, resulting in a remainder of 165.
The next digit of our result is 9. 
Result so far: 27513.9
If we subtract 6165 from 6330, we get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Moving on to step 10:
685 can be fit into 1650 2 times, resulting in a remainder of 280.
Write down 2 as next digit of the result. 
Result so far: 27513.92
The remainder is 280 after subtracting 1370 from 1650.
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 11:
The number 685 fits into 2800 4 times, leaving a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 27513.924
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.

Going ahead to step 12:
The number 685 fits into 600 0 times, leaving a remainder of 600.
The next digit of our result is 0. 
Result so far: 27513.924
If we subtract 0 from 600, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 13:
6000 divided by 685 is 8 with a remainder of 520.
The next digit of our result is 8. 
Result so far: 27513.92408
Subtracting 5480 from 6000 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 14:
685 can be fit into 5200 7 times, resulting in a remainder of 405.
Record the quotient 7 as the next digit in the result. 
Result so far: 27513.924087
If we take 4795 away from 5200, we end up with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

On to step 15:
The number 685 fits into 4050 5 times, leaving a remainder of 625.
Put 5 as the next digit of the answer. 
Result so far: 27513.9240875
If we subtract 3425 from 4050, we get 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Let's proceed to step 16:
685 goes into 6250 9 times with a remainder of 85.
Put 9 as the next digit of the answer. 
Result so far: 27513.92408759
If we subtract 6165 from 6250, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Our division results in 27513.92408759 with a remaining 8.5e-08.
