We're dividing 18080903 by 298 
The aim is to understand the frequency of 298 in 18080903.

Let's proceed to step 1:
298 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 298

Moving on to step 2:
298 goes into 18 0 times with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 298

On to step 3:
298 goes into 180 0 times with a remainder of 180.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 180 to get 180.
Grab the next digit (8) from the dividend, add it to 180, then carry on: 1808 / 298

Step 4:
298 can be fit into 1808 6 times, resulting in a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 1788 from 1808 leaves us with 20.
Fetch the next digit (0) from the dividend, attach it to 20 and continue: 200 / 298

Advancing to step 5:
200 divided by 298 is 0 with a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 60.0
The remainder is 200 after subtracting 0 from 200.
Grab the next digit (9) from the dividend, add it to 200, then carry on: 2009 / 298

Going ahead to step 6:
The number 298 fits into 2009 6 times, leaving a remainder of 221.
Write down 6 as next digit of the result. 
Result so far: 606.0
The remainder is 221 after subtracting 1788 from 2009.
Fetch the next digit (0) from the dividend, attach it to 221 and continue: 2210 / 298

Moving on to step 7:
298 goes into 2210 7 times with a remainder of 124.
Put 7 as the next digit of the answer. 
Result so far: 6067.0
If we take 2086 away from 2210, we end up with 124.
Fetch the next digit (3) from the dividend, attach it to 124 and continue: 1243 / 298

Advancing to step 8:
When dividing 1243 by 298, we get 4 with a remainder of 51.
Put 4 as the next digit of the answer. 
Result so far: 60674.0
Subtracting 1192 from 1243 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 9:
298 goes into 510 1 times with a remainder of 212.
Record the quotient 1 as the next digit in the result. 
Result so far: 60674.1
Subtract 298 from 510 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Advancing to step 10:
If we divide 2120 by 298, we get 7 and a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 60674.17
Subtracting 2086 from 2120 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 11:
298 can be fit into 340 1 times, resulting in a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 60674.171
If we subtract 298 from 340, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 12:
The number 298 fits into 420 1 times, leaving a remainder of 122.
Put 1 as the next digit of the answer. 
Result so far: 60674.1711
If we take 298 away from 420, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

After the division, we end up with 60674.1711 and a remainder of 0.00122.
