We divide 959023 by 81
The aim is to understand the frequency of 81 in 959023.

Step 1:
81 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 81

Let's proceed to step 2:
The number 81 fits into 95 1 times, leaving a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 81 from 95 leaves us with 14.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 81

Moving on to step 3:
81 goes into 149 1 times with a remainder of 68.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 81 from 149 and we're left with 68.
Take the next digit (0) from the dividend and append it to 68, then repeat: 680 / 81

Going ahead to step 4:
The number 81 fits into 680 8 times, leaving a remainder of 32.
The next digit of our result is 8. 
Result so far: 118.0
Subtract 648 from 680 to get 32.
Bring next digit (2) of the dividend behind the 32 and repeat the process: 322 / 81

On to step 5:
If we divide 322 by 81, we get 3 and a remainder of 79.
Write down 3 as next digit of the result. 
Result so far: 1183.0
Subtracting 243 from 322 leaves us with 79.
Grab the next digit (3) from the dividend, add it to 79, then carry on: 793 / 81

Let's proceed to step 6:
The number 81 fits into 793 9 times, leaving a remainder of 64.
Write down 9 as next digit of the result. 
Result so far: 11839.0
If we subtract 729 from 793, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 7:
The number 81 fits into 640 7 times, leaving a remainder of 73.
Put 7 as the next digit of the answer. 
Result so far: 11839.7
The remainder is 73 after subtracting 567 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 8:
If we divide 730 by 81, we get 9 and a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 11839.79
If we take 729 away from 730, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
If we divide 10 by 81, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 11839.79
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing 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: 11839.7901
The remainder is 19 after subtracting 81 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 11:
When dividing 190 by 81, we get 2 with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 11839.79012
Subtract 162 from 190 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 12:
81 can be fit into 280 3 times, resulting in a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 11839.790123
If we take 243 away from 280, we end up with 37.
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:
If we divide 370 by 81, we get 4 and a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 11839.7901234
If we take 324 away from 370, we end up 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.

On to step 14:
460 divided by 81 is 5 with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 11839.79012345
Deduct 405 from 460 and we're left 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.

After the division, we end up with 11839.79012345 and a remainder of 5.5e-08.
