18948 divided by 81 
The aim is to understand the frequency of 81 in 18948.

On to step 1:
The number 81 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 81

Let's proceed to step 2:
81 goes into 18 0 times with a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Bring next digit (9) of the dividend behind the 18 and repeat the process: 189 / 81

Moving on to step 3:
81 can be fit into 189 2 times, resulting in a remainder of 27.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 162 from 189, we get 27.
Bring next digit (4) of the dividend behind the 27 and repeat the process: 274 / 81

Advancing to step 4:
The number 81 fits into 274 3 times, leaving a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 23.0
Subtracting 243 from 274 leaves us with 31.
Include the next digit (8) from the dividend after 31, then repeat: 318 / 81

Going ahead to step 5:
When dividing 318 by 81, we get 3 with a remainder of 75.
Put 3 as the next digit of the answer. 
Result so far: 233.0
If we subtract 243 from 318, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 6:
81 goes into 750 9 times with a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 233.9
If we subtract 729 from 750, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
81 goes into 210 2 times with a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 233.92
If we take 162 away from 210, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 8:
480 divided by 81 is 5 with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 233.925
If we subtract 405 from 480, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 9:
81 goes into 750 9 times with a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 233.9259
Deduct 729 from 750 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 10:
If we divide 210 by 81, we get 2 and a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 233.92592
If we take 162 away from 210, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 11:
81 can be fit into 480 5 times, resulting in a remainder of 75.
The next digit of our result is 5. 
Result so far: 233.925925
Subtracting 405 from 480 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 12:
81 can be fit into 750 9 times, resulting in a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 233.9259259
If we subtract 729 from 750, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 13:
If we divide 210 by 81, we get 2 and a remainder of 48.
The next digit of our result is 2. 
Result so far: 233.92592592
The remainder is 48 after subtracting 162 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 233.92592592 and a remainder of 4.8e-08.
