248847 divided by 81 
The aim is to understand the frequency of 81 in 248847.

On to step 1:
81 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 81

On to step 2:
81 can be fit into 24 0 times, resulting in a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 24 and we're left with 24.
Take the next digit (8) from the dividend and append it to 24, then repeat: 248 / 81

Moving on to step 3:
When dividing 248 by 81, we get 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 5 after subtracting 243 from 248.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 81

Let's proceed to step 4:
81 can be fit into 58 0 times, resulting in a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
The remainder is 58 after subtracting 0 from 58.
Take the next digit (4) from the dividend and append it to 58, then repeat: 584 / 81

Step 5:
81 goes into 584 7 times with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 307.0
The remainder is 17 after subtracting 567 from 584.
Bring next digit (7) of the dividend behind the 17 and repeat the process: 177 / 81

Moving on to step 6:
177 divided by 81 is 2 with a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 3072.0
Subtract 162 from 177 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
81 can be fit into 150 1 times, resulting in a remainder of 69.
Record the quotient 1 as the next digit in the result. 
Result so far: 3072.1
If we take 81 away from 150, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 8:
The number 81 fits into 690 8 times, leaving a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 3072.18
Subtract 648 from 690 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 9:
If we divide 420 by 81, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 3072.185
The remainder is 15 after subtracting 405 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 10:
The number 81 fits into 150 1 times, leaving a remainder of 69.
Write down 1 as next digit of the result. 
Result so far: 3072.1851
Subtract 81 from 150 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 11:
If we divide 690 by 81, we get 8 and a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 3072.18518
The remainder is 42 after subtracting 648 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 12:
The number 81 fits into 420 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 3072.185185
If we take 405 away from 420, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 13:
81 goes into 150 1 times with a remainder of 69.
The number 1 becomes the next digit in our result. 
Result so far: 3072.1851851
Deduct 81 from 150 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 14:
If we divide 690 by 81, we get 8 and a remainder of 42.
The next digit of our result is 8. 
Result so far: 3072.18518518
Subtract 648 from 690 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final outcome is 3072.18518518, with a leftover of 4.2e-08.
