696011 ÷ 81 
The aim is to understand the frequency of 81 in 696011.

Step 1:
The number 81 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 81

Let's proceed to step 2:
69 divided by 81 is 0 with a remainder of 69.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 69 leaves us with 69.
Grab the next digit (6) from the dividend, add it to 69, then carry on: 696 / 81

On to step 3:
81 goes into 696 8 times with a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 648 away from 696, we end up with 48.
Include the next digit (0) from the dividend after 48, then repeat: 480 / 81

Moving on to step 4:
480 divided by 81 is 5 with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 85.0
If we subtract 405 from 480, we get 75.
Include the next digit (1) from the dividend after 75, then repeat: 751 / 81

Going ahead to step 5:
81 goes into 751 9 times with a remainder of 22.
The next digit of our result is 9. 
Result so far: 859.0
Subtract 729 from 751 to get 22.
Bring next digit (1) of the dividend behind the 22 and repeat the process: 221 / 81

Step 6:
If we divide 221 by 81, we get 2 and a remainder of 59.
The next digit of our result is 2. 
Result so far: 8592.0
Subtract 162 from 221 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 7:
If we divide 590 by 81, we get 7 and a remainder of 23.
The next digit of our result is 7. 
Result so far: 8592.7
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.

Moving on to step 8:
If we divide 230 by 81, we get 2 and a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 8592.72
The remainder is 68 after subtracting 162 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 9:
The number 81 fits into 680 8 times, leaving a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 8592.728
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.

Let's proceed to step 10:
81 goes into 320 3 times with a remainder of 77.
Use 3 as the next digit of our solution. 
Result so far: 8592.7283
Deduct 243 from 320 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 11:
770 divided by 81 is 9 with a remainder of 41.
The next digit of our result is 9. 
Result so far: 8592.72839
Deduct 729 from 770 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 12:
81 goes into 410 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 8592.728395
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.

On to step 13:
If we divide 50 by 81, we get 0 and a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 8592.728395
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 14:
If we divide 500 by 81, we get 6 and a remainder of 14.
The next digit of our result is 6. 
Result so far: 8592.72839506
Subtracting 486 from 500 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The quotient of the division is 8592.72839506, and the remainder is 1.4e-08.
