We divide 956534 by 81
The aim is to understand the frequency of 81 in 956534.

On to step 1:
When dividing 9 by 81, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (5) from the dividend to 9 and continue with: 95 / 81

Going ahead to step 2:
If we divide 95 by 81, we get 1 and a remainder of 14.
The next digit of our result is 1. 
Result so far: 1.0
If we take 81 away from 95, we end up with 14.
Grab the next digit (6) from the dividend, add it to 14, then carry on: 146 / 81

Step 3:
81 can be fit into 146 1 times, resulting in a remainder of 65.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 81 from 146 leaves us with 65.
Bring next digit (5) of the dividend behind the 65 and repeat the process: 655 / 81

Step 4:
If we divide 655 by 81, we get 8 and a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 118.0
If we subtract 648 from 655, we get 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 81

Step 5:
73 divided by 81 is 0 with a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 1180.0
If we take 0 away from 73, we end up with 73.
Include the next digit (4) from the dividend after 73, then repeat: 734 / 81

Step 6:
81 can be fit into 734 9 times, resulting in a remainder of 5.
The next digit of our result is 9. 
Result so far: 11809.0
Subtract 729 from 734 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
The number 81 fits into 50 0 times, leaving a remainder of 50.
The next digit of our result is 0. 
Result so far: 11809.0
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
81 goes into 500 6 times with a remainder of 14.
The next digit of our result is 6. 
Result so far: 11809.06
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.

Moving on to step 9:
The number 81 fits into 140 1 times, leaving a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 11809.061
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 10:
When dividing 590 by 81, we get 7 with a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 11809.0617
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.

Let's proceed to step 11:
If we divide 230 by 81, we get 2 and a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 11809.06172
Subtracting 162 from 230 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.

Step 12:
81 goes into 680 8 times with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 11809.061728
Subtracting 648 from 680 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 13:
The number 81 fits into 320 3 times, leaving a remainder of 77.
The number 3 becomes the next digit in our result. 
Result so far: 11809.0617283
If we subtract 243 from 320, we get 77.
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 14:
When dividing 770 by 81, we get 9 with a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 11809.06172839
Subtract 729 from 770 to 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.

The quotient of the division is 11809.06172839, and the remainder is 4.1e-08.
