483637 ÷ 18 
The aim is to understand the frequency of 18 in 483637.

On to step 1:
4 divided by 18 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 18

Going ahead to step 2:
When dividing 48 by 18, we get 2 with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 36 from 48 and we're left with 12.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 18

On to step 3:
123 divided by 18 is 6 with a remainder of 15.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
The remainder is 15 after subtracting 108 from 123.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 18

Let's proceed to step 4:
18 goes into 156 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 268.0
If we take 144 away from 156, we end up with 12.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 18

Step 5:
123 divided by 18 is 6 with a remainder of 15.
Write down 6 as next digit of the result. 
Result so far: 2686.0
If we subtract 108 from 123, we get 15.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 18

Advancing to step 6:
157 divided by 18 is 8 with a remainder of 13.
The next digit of our result is 8. 
Result so far: 26868.0
If we subtract 144 from 157, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
If we divide 130 by 18, we get 7 and a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 26868.7
If we subtract 126 from 130, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
If we divide 40 by 18, we get 2 and a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 26868.72
If we take 36 away from 40, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
18 can be fit into 40 2 times, resulting in a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 26868.722
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 26868.722, and the remainder is 0.0004.
