Let's divide 703780 by 18
The aim is to understand the frequency of 18 in 703780.

Moving on to step 1:
The number 18 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 18

Going ahead to step 2:
18 goes into 70 3 times with a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 54 from 70 leaves us with 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 18

Step 3:
163 divided by 18 is 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
The remainder is 1 after subtracting 162 from 163.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 18

Advancing to step 4:
18 goes into 17 0 times with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 390.0
If we take 0 away from 17, we end up with 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 18

Let's proceed to step 5:
The number 18 fits into 178 9 times, leaving a remainder of 16.
Put 9 as the next digit of the answer. 
Result so far: 3909.0
Subtracting 162 from 178 leaves us with 16.
Fetch the next digit (0) from the dividend, attach it to 16 and continue: 160 / 18

Step 6:
18 goes into 160 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 39098.0
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 7:
160 divided by 18 is 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 39098.8
Deduct 144 from 160 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
If we divide 160 by 18, we get 8 and a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 39098.88
If we take 144 away from 160, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 39098.88 with a remaining 0.016.
