We're dividing 137507 by 18 
The aim is to understand the frequency of 18 in 137507.

Moving on to step 1:
1 divided by 18 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 18

Advancing to step 2:
18 goes into 13 0 times with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Take the next digit (7) from the dividend and append it to 13, then repeat: 137 / 18

Let's proceed to step 3:
The number 18 fits into 137 7 times, leaving a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 126 from 137 leaves us with 11.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 18

Going ahead to step 4:
When dividing 115 by 18, we get 6 with a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 76.0
Subtracting 108 from 115 leaves us with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 18

Going ahead to step 5:
18 goes into 70 3 times with a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 763.0
Deduct 54 from 70 and we're left with 16.
Include the next digit (7) from the dividend after 16, then repeat: 167 / 18

Going ahead to step 6:
If we divide 167 by 18, we get 9 and a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 7639.0
The remainder is 5 after subtracting 162 from 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
18 goes into 50 2 times with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 7639.2
If we subtract 36 from 50, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
If we divide 140 by 18, we get 7 and a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 7639.27
If we subtract 126 from 140, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
18 can be fit into 140 7 times, resulting in a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 7639.277
Deduct 126 from 140 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The quotient of the division is 7639.277, and the remainder is 0.0014.
