We divide 701284 by 81
The aim is to understand the frequency of 81 in 701284.

Let's proceed to step 1:
The number 81 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 81

Moving on to step 2:
The number 81 fits into 70 0 times, leaving a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 70 leaves us with 70.
Fetch the next digit (1) from the dividend, attach it to 70 and continue: 701 / 81

Going ahead to step 3:
If we divide 701 by 81, we get 8 and a remainder of 53.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 648 from 701 leaves us with 53.
Append the next digit (2) from the dividend to 53 and continue with: 532 / 81

Advancing to step 4:
If we divide 532 by 81, we get 6 and a remainder of 46.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
Subtracting 486 from 532 leaves us with 46.
Fetch the next digit (8) from the dividend, attach it to 46 and continue: 468 / 81

Advancing to step 5:
81 goes into 468 5 times with a remainder of 63.
The number 5 becomes the next digit in our result. 
Result so far: 865.0
If we subtract 405 from 468, we get 63.
Bring next digit (4) of the dividend behind the 63 and repeat the process: 634 / 81

Step 6:
81 goes into 634 7 times with a remainder of 67.
Use 7 as the next digit of our solution. 
Result so far: 8657.0
If we subtract 567 from 634, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 7:
670 divided by 81 is 8 with a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 8657.8
If we take 648 away from 670, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 8:
The number 81 fits into 220 2 times, leaving a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 8657.82
Subtracting 162 from 220 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 9:
When dividing 580 by 81, we get 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 8657.827
Subtracting 567 from 580 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 10:
81 can be fit into 130 1 times, resulting in a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 8657.8271
The remainder is 49 after subtracting 81 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 11:
When dividing 490 by 81, we get 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 8657.82716
If we take 486 away from 490, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
When dividing 40 by 81, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 8657.82716
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 13:
When dividing 400 by 81, we get 4 with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 8657.8271604
Subtract 324 from 400 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 14:
The number 81 fits into 760 9 times, leaving a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 8657.82716049
If we take 729 away from 760, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The quotient of the division is 8657.82716049, and the remainder is 3.1e-08.
