Let's divide 81208171 by 812
The aim is to understand the frequency of 812 in 81208171.

On to step 1:
8 divided by 812 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 812

Advancing to step 2:
If we divide 81 by 812, we get 0 and a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Include the next digit (2) from the dividend after 81, then repeat: 812 / 812

Step 3:
If we divide 812 by 812, we get 1 and a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 812 from 812 leaves us with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 812

Step 4:
If we divide 0 by 812, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 0 after subtracting 0 from 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 812

Let's proceed to step 5:
The number 812 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 100.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 812

Advancing to step 6:
If we divide 81 by 812, we get 0 and a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 1000.0
If we subtract 0 from 81, we get 81.
Bring next digit (7) of the dividend behind the 81 and repeat the process: 817 / 812

Advancing to step 7:
817 divided by 812 is 1 with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 10001.0
The remainder is 5 after subtracting 812 from 817.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 812

Moving on to step 8:
If we divide 51 by 812, we get 0 and a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 100010.0
Subtracting 0 from 51 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 9:
If we divide 510 by 812, we get 0 and a remainder of 510.
The number 0 becomes the next digit in our result. 
Result so far: 100010.0
If we take 0 away from 510, we end up with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Moving on to step 10:
5100 divided by 812 is 6 with a remainder of 228.
Write down 6 as next digit of the result. 
Result so far: 100010.06
Subtract 4872 from 5100 to get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 11:
2280 divided by 812 is 2 with a remainder of 656.
The number 2 becomes the next digit in our result. 
Result so far: 100010.062
Subtract 1624 from 2280 to get 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Step 12:
812 goes into 6560 8 times with a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 100010.0628
Subtract 6496 from 6560 to 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.

Going ahead to step 13:
812 goes into 640 0 times with a remainder of 640.
Write down 0 as next digit of the result. 
Result so far: 100010.0628
If we subtract 0 from 640, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Let's proceed to step 14:
6400 divided by 812 is 7 with a remainder of 716.
Use 7 as the next digit of our solution. 
Result so far: 100010.062807
Subtracting 5684 from 6400 leaves us with 716.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7160, and continue the process.

Moving on to step 15:
7160 divided by 812 is 8 with a remainder of 664.
Use 8 as the next digit of our solution. 
Result so far: 100010.0628078
Subtract 6496 from 7160 to get 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

On to step 16:
When dividing 6640 by 812, we get 8 with a remainder of 144.
Write down 8 as next digit of the result. 
Result so far: 100010.06280788
Subtract 6496 from 6640 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

The quotient of the division is 100010.06280788, and the remainder is 1.44e-07.
