847275 ÷ 81 
The aim is to understand the frequency of 81 in 847275.

On to step 1:
The number 81 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 81

Advancing to step 2:
81 can be fit into 84 1 times, resulting in a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 81 from 84 and we're left with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 81

Moving on to step 3:
81 can be fit into 37 0 times, resulting in a remainder of 37.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 37 and we're left with 37.
Append the next digit (2) from the dividend to 37 and continue with: 372 / 81

Let's proceed to step 4:
372 divided by 81 is 4 with a remainder of 48.
The next digit of our result is 4. 
Result so far: 104.0
If we take 324 away from 372, we end up with 48.
Append the next digit (7) from the dividend to 48 and continue with: 487 / 81

Going ahead to step 5:
The number 81 fits into 487 6 times, leaving a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 1046.0
If we take 486 away from 487, we end up with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 81

Let's proceed to step 6:
If we divide 15 by 81, we get 0 and a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 10460.0
Subtract 0 from 15 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:
The number 81 fits into 150 1 times, leaving a remainder of 69.
Record the quotient 1 as the next digit in the result. 
Result so far: 10460.1
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.

Advancing to step 8:
81 can be fit into 690 8 times, resulting in a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 10460.18
If we subtract 648 from 690, we 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.

Moving on to step 9:
81 goes into 420 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 10460.185
Subtract 405 from 420 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.

Moving on to step 10:
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: 10460.1851
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.

On to step 11:
If we divide 690 by 81, we get 8 and a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 10460.18518
If we take 648 away from 690, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 12:
81 goes into 420 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 10460.185185
Deduct 405 from 420 and we're left 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.

Going ahead to step 13:
81 goes into 150 1 times with a remainder of 69.
Write down 1 as next digit of the result. 
Result so far: 10460.1851851
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.

Going ahead to step 14:
The number 81 fits into 690 8 times, leaving a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 10460.18518518
Subtracting 648 from 690 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

In conclusion, the division gives 10460.18518518 with a balance of 4.2e-08.
