We're dividing 598428 by 18 
The aim is to understand the frequency of 18 in 598428.

Going ahead to step 1:
18 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 18

Advancing to step 2:
If we divide 59 by 18, we get 3 and a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 54 from 59 and we're left with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 18

On to step 3:
When dividing 58 by 18, we get 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 33.0
Subtracting 54 from 58 leaves us with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 18

Advancing to step 4:
If we divide 44 by 18, we get 2 and a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 332.0
If we subtract 36 from 44, we get 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 18

Step 5:
82 divided by 18 is 4 with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 3324.0
Subtracting 72 from 82 leaves us with 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 18

Advancing to step 6:
The number 18 fits into 108 6 times, leaving a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 33246.0
If we subtract 108 from 108, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
If we divide 0 by 18, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 33246.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
If we divide 0 by 18, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 33246.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 33246.0 with a remainder of 0.0.
