Let's divide 779206 by 81
The aim is to understand the frequency of 81 in 779206.

Step 1:
If we divide 7 by 81, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 81

Step 2:
81 can be fit into 77 0 times, resulting in a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Bring next digit (9) of the dividend behind the 77 and repeat the process: 779 / 81

On to step 3:
779 divided by 81 is 9 with a remainder of 50.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 729 from 779 to get 50.
Append the next digit (2) from the dividend to 50 and continue with: 502 / 81

Step 4:
502 divided by 81 is 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 96.0
The remainder is 16 after subtracting 486 from 502.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 81

Moving on to step 5:
81 can be fit into 160 1 times, resulting in a remainder of 79.
The next digit of our result is 1. 
Result so far: 961.0
Deduct 81 from 160 and we're left with 79.
Grab the next digit (6) from the dividend, add it to 79, then carry on: 796 / 81

Advancing to step 6:
When dividing 796 by 81, we get 9 with a remainder of 67.
Put 9 as the next digit of the answer. 
Result so far: 9619.0
If we subtract 729 from 796, 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.

Going ahead to step 7:
The number 81 fits into 670 8 times, leaving a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 9619.8
Deduct 648 from 670 and we're left 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.

On to step 8:
220 divided by 81 is 2 with a remainder of 58.
Record the quotient 2 as the next digit in the result. 
Result so far: 9619.82
Subtract 162 from 220 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 9:
When dividing 580 by 81, we get 7 with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 9619.827
The remainder is 13 after subtracting 567 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving 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: 9619.8271
If we take 81 away from 130, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 11:
If we divide 490 by 81, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 9619.82716
If we subtract 486 from 490, we get 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.
The number 0 becomes the next digit in our result. 
Result so far: 9619.82716
If we subtract 0 from 40, we 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.

Moving on 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: 9619.8271604
If we take 324 away from 400, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 14:
81 goes into 760 9 times with a remainder of 31.
The next digit of our result is 9. 
Result so far: 9619.82716049
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 9619.82716049, and the remainder is 3.1e-08.
