We're dividing 17388884 by 698 
The aim is to understand the frequency of 698 in 17388884.

Advancing to step 1:
698 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
The remainder is 1 after subtracting 0 from 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 698

Going ahead to step 2:
698 can be fit into 17 0 times, resulting in a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Include the next digit (3) from the dividend after 17, then repeat: 173 / 698

Advancing to step 3:
If we divide 173 by 698, we get 0 and a remainder of 173.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 173 after subtracting 0 from 173.
Take the next digit (8) from the dividend and append it to 173, then repeat: 1738 / 698

On to step 4:
1738 divided by 698 is 2 with a remainder of 342.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 1396 from 1738 leaves us with 342.
Include the next digit (8) from the dividend after 342, then repeat: 3428 / 698

Going ahead to step 5:
698 goes into 3428 4 times with a remainder of 636.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
The remainder is 636 after subtracting 2792 from 3428.
Append the next digit (8) from the dividend to 636 and continue with: 6368 / 698

Going ahead to step 6:
6368 divided by 698 is 9 with a remainder of 86.
Record the quotient 9 as the next digit in the result. 
Result so far: 249.0
Subtract 6282 from 6368 to get 86.
Grab the next digit (8) from the dividend, add it to 86, then carry on: 868 / 698

Moving on to step 7:
868 divided by 698 is 1 with a remainder of 170.
Put 1 as the next digit of the answer. 
Result so far: 2491.0
If we take 698 away from 868, we end up with 170.
Fetch the next digit (4) from the dividend, attach it to 170 and continue: 1704 / 698

On to step 8:
If we divide 1704 by 698, we get 2 and a remainder of 308.
The next digit of our result is 2. 
Result so far: 24912.0
The remainder is 308 after subtracting 1396 from 1704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Advancing to step 9:
When dividing 3080 by 698, we get 4 with a remainder of 288.
Record the quotient 4 as the next digit in the result. 
Result so far: 24912.4
If we subtract 2792 from 3080, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Step 10:
If we divide 2880 by 698, we get 4 and a remainder of 88.
The number 4 becomes the next digit in our result. 
Result so far: 24912.44
Subtracting 2792 from 2880 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

The final result is 24912.44 with a remainder of 0.088.
