We're dividing 316859 by 81 
The aim is to understand the frequency of 81 in 316859.

Going ahead to step 1:
81 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 81

Moving on to step 2:
81 can be fit into 31 0 times, resulting in a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Take the next digit (6) from the dividend and append it to 31, then repeat: 316 / 81

Let's proceed to step 3:
81 goes into 316 3 times with a remainder of 73.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 243 away from 316, we end up with 73.
Take the next digit (8) from the dividend and append it to 73, then repeat: 738 / 81

Moving on to step 4:
81 goes into 738 9 times with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 39.0
Subtracting 729 from 738 leaves us with 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 81

Going ahead to step 5:
If we divide 95 by 81, we get 1 and a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 391.0
If we take 81 away from 95, we end up with 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 81

Step 6:
81 can be fit into 149 1 times, resulting in a remainder of 68.
The number 1 becomes the next digit in our result. 
Result so far: 3911.0
Subtracting 81 from 149 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 7:
81 can be fit into 680 8 times, resulting in a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 3911.8
If we subtract 648 from 680, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 8:
81 goes into 320 3 times with a remainder of 77.
The next digit of our result is 3. 
Result so far: 3911.83
The remainder is 77 after subtracting 243 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 9:
81 can be fit into 770 9 times, resulting in a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 3911.839
If we subtract 729 from 770, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 10:
81 goes into 410 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 3911.8395
Subtracting 405 from 410 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 11:
When dividing 50 by 81, we get 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 3911.8395
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 12:
When dividing 500 by 81, we get 6 with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 3911.839506
Subtract 486 from 500 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 13:
When dividing 140 by 81, we get 1 with a remainder of 59.
Record the quotient 1 as the next digit in the result. 
Result so far: 3911.8395061
Deduct 81 from 140 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 14:
81 goes into 590 7 times with a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 3911.83950617
Subtract 567 from 590 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

In conclusion, the division gives 3911.83950617 with a balance of 2.3e-08.
