We're dividing 384345 by 81 
The aim is to understand the frequency of 81 in 384345.

Moving on to step 1:
If we divide 3 by 81, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 81

Advancing to step 2:
81 goes into 38 0 times with a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Grab the next digit (4) from the dividend, add it to 38, then carry on: 384 / 81

On to step 3:
If we divide 384 by 81, we get 4 and a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 324 from 384, we get 60.
Bring next digit (3) of the dividend behind the 60 and repeat the process: 603 / 81

Step 4:
81 goes into 603 7 times with a remainder of 36.
Put 7 as the next digit of the answer. 
Result so far: 47.0
Subtract 567 from 603 to get 36.
Bring next digit (4) of the dividend behind the 36 and repeat the process: 364 / 81

Going ahead to step 5:
The number 81 fits into 364 4 times, leaving a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 474.0
Deduct 324 from 364 and we're left with 40.
Grab the next digit (5) from the dividend, add it to 40, then carry on: 405 / 81

Moving on to step 6:
81 can be fit into 405 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 4745.0
If we take 405 away from 405, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
If we divide 0 by 81, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4745.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
81 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4745.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 4745.0, and the remainder is 0.0.
