We're dividing 371048 by 18 
The aim is to understand the frequency of 18 in 371048.

Moving on to step 1:
The number 18 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 18

Let's proceed to step 2:
18 goes into 37 2 times with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 36 away from 37, we end up with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 18

Moving on to step 3:
11 divided by 18 is 0 with a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we subtract 0 from 11, we get 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 18

Advancing to step 4:
110 divided by 18 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 206.0
If we take 108 away from 110, we end up with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 18

Step 5:
If we divide 24 by 18, we get 1 and a remainder of 6.
The next digit of our result is 1. 
Result so far: 2061.0
Deduct 18 from 24 and we're left with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 18

Let's proceed to step 6:
If we divide 68 by 18, we get 3 and a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 20613.0
The remainder is 14 after subtracting 54 from 68.
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 7:
140 divided by 18 is 7 with a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 20613.7
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.

Going ahead to step 8:
When dividing 140 by 18, we get 7 with a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 20613.77
If we take 126 away from 140, we end up 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.

After the division, we end up with 20613.77 and a remainder of 0.014.
