We divide 576472 by 81
The aim is to understand the frequency of 81 in 576472.

On to step 1:
81 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 81

Advancing to step 2:
81 goes into 57 0 times with a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Include the next digit (6) from the dividend after 57, then repeat: 576 / 81

Advancing to step 3:
576 divided by 81 is 7 with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 567 from 576 and we're left with 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 81

Going ahead to step 4:
81 can be fit into 94 1 times, resulting in a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 71.0
Subtracting 81 from 94 leaves us with 13.
Take the next digit (7) from the dividend and append it to 13, then repeat: 137 / 81

Advancing to step 5:
81 goes into 137 1 times with a remainder of 56.
Put 1 as the next digit of the answer. 
Result so far: 711.0
Deduct 81 from 137 and we're left with 56.
Bring next digit (2) of the dividend behind the 56 and repeat the process: 562 / 81

On to step 6:
81 goes into 562 6 times with a remainder of 76.
Write down 6 as next digit of the result. 
Result so far: 7116.0
If we subtract 486 from 562, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 7:
760 divided by 81 is 9 with a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 7116.9
The remainder is 31 after subtracting 729 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 8:
When dividing 310 by 81, we get 3 with a remainder of 67.
Record the quotient 3 as the next digit in the result. 
Result so far: 7116.93
The remainder is 67 after subtracting 243 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 9:
81 can be fit into 670 8 times, resulting in a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 7116.938
If we take 648 away from 670, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 10:
If we divide 220 by 81, we get 2 and a remainder of 58.
Use 2 as the next digit of our solution. 
Result so far: 7116.9382
If we subtract 162 from 220, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 11:
The number 81 fits into 580 7 times, leaving a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 7116.93827
The remainder is 13 after subtracting 567 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 12:
If we divide 130 by 81, we get 1 and a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 7116.938271
The remainder is 49 after subtracting 81 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 13:
81 can be fit into 490 6 times, resulting in a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 7116.9382716
Subtract 486 from 490 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 14:
When dividing 40 by 81, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 7116.9382716
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 7116.9382716 with a balance of 4e-08.
