259162 divided by 18 
The aim is to understand the frequency of 18 in 259162.

On to step 1:
The number 18 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 18

Advancing to step 2:
If we divide 25 by 18, we get 1 and a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 18 from 25 and we're left with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 18

Step 3:
When dividing 79 by 18, we get 4 with a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we take 72 away from 79, we end up with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 18

Going ahead to step 4:
18 goes into 71 3 times with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 143.0
Deduct 54 from 71 and we're left with 17.
Grab the next digit (6) from the dividend, add it to 17, then carry on: 176 / 18

Let's proceed to step 5:
If we divide 176 by 18, we get 9 and a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 1439.0
If we take 162 away from 176, we end up with 14.
Append the next digit (2) from the dividend to 14 and continue with: 142 / 18

Let's proceed to step 6:
If we divide 142 by 18, we get 7 and a remainder of 16.
Put 7 as the next digit of the answer. 
Result so far: 14397.0
If we subtract 126 from 142, 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.

Advancing to step 7:
18 goes into 160 8 times with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 14397.8
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:
18 can be fit into 160 8 times, resulting in a remainder of 16.
The next digit of our result is 8. 
Result so far: 14397.88
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 14397.88, and the remainder is 0.016.
