We divide 410734 by 81
The aim is to understand the frequency of 81 in 410734.

On to step 1:
4 divided by 81 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 81

On to step 2:
The number 81 fits into 41 0 times, leaving a remainder of 41.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 41 to get 41.
Take the next digit (0) from the dividend and append it to 41, then repeat: 410 / 81

Step 3:
81 goes into 410 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 405 from 410 leaves us with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 81

Moving on to step 4:
57 divided by 81 is 0 with a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 50.0
If we take 0 away from 57, we end up with 57.
Include the next digit (3) from the dividend after 57, then repeat: 573 / 81

On to step 5:
The number 81 fits into 573 7 times, leaving a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 507.0
Subtract 567 from 573 to get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 81

Moving on to step 6:
64 divided by 81 is 0 with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 5070.0
The remainder is 64 after subtracting 0 from 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 7:
If we divide 640 by 81, we get 7 and a remainder of 73.
Use 7 as the next digit of our solution. 
Result so far: 5070.7
If we take 567 away from 640, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 8:
If we divide 730 by 81, we get 9 and a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 5070.79
The remainder is 1 after subtracting 729 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
When dividing 10 by 81, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 5070.79
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
81 goes into 100 1 times with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 5070.7901
If we subtract 81 from 100, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 11:
81 goes into 190 2 times with a remainder of 28.
The next digit of our result is 2. 
Result so far: 5070.79012
The remainder is 28 after subtracting 162 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 12:
81 goes into 280 3 times with a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 5070.790123
The remainder is 37 after subtracting 243 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 13:
81 goes into 370 4 times with a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 5070.7901234
Deduct 324 from 370 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 14:
81 goes into 460 5 times with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 5070.79012345
If we take 405 away from 460, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The final outcome is 5070.79012345, with a leftover of 5.5e-08.
