Let's divide 1698 by 85
The aim is to understand the frequency of 85 in 1698.

Advancing to step 1:
If we divide 1 by 85, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 85

Advancing to step 2:
When dividing 16 by 85, we get 0 with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Include the next digit (9) from the dividend after 16, then repeat: 169 / 85

Going ahead to step 3:
When dividing 169 by 85, we get 1 with a remainder of 84.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 85 away from 169, we end up with 84.
Take the next digit (8) from the dividend and append it to 84, then repeat: 848 / 85

Step 4:
When dividing 848 by 85, we get 9 with a remainder of 83.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtract 765 from 848 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Let's proceed to step 5:
85 can be fit into 830 9 times, resulting in a remainder of 65.
Put 9 as the next digit of the answer. 
Result so far: 19.9
Subtract 765 from 830 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 6:
When dividing 650 by 85, we get 7 with a remainder of 55.
The next digit of our result is 7. 
Result so far: 19.97
Subtract 595 from 650 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 7:
When dividing 550 by 85, we get 6 with a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 19.976
Subtract 510 from 550 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
When dividing 400 by 85, we get 4 with a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 19.9764
If we take 340 away from 400, 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.

Let's proceed to step 9:
If we divide 600 by 85, we get 7 and a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 19.97647
If we subtract 595 from 600, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 10:
85 can be fit into 50 0 times, resulting in a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 19.97647
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 11:
When dividing 500 by 85, we get 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 19.9764705
Subtracting 425 from 500 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 12:
If we divide 750 by 85, we get 8 and a remainder of 70.
Use 8 as the next digit of our solution. 
Result so far: 19.97647058
If we take 680 away from 750, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final result is 19.97647058 with a remainder of 7e-08.
