We divide 81890285 by 822
The aim is to understand the frequency of 822 in 81890285.

Advancing to step 1:
8 divided by 822 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 822

Going ahead to step 2:
822 can be fit into 81 0 times, resulting in a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Take the next digit (8) from the dividend and append it to 81, then repeat: 818 / 822

On to step 3:
When dividing 818 by 822, we get 0 with a remainder of 818.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 818 after subtracting 0 from 818.
Fetch the next digit (9) from the dividend, attach it to 818 and continue: 8189 / 822

Moving on to step 4:
If we divide 8189 by 822, we get 9 and a remainder of 791.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 7398 from 8189 to get 791.
Include the next digit (0) from the dividend after 791, then repeat: 7910 / 822

Let's proceed to step 5:
If we divide 7910 by 822, we get 9 and a remainder of 512.
The next digit of our result is 9. 
Result so far: 99.0
If we take 7398 away from 7910, we end up with 512.
Bring next digit (2) of the dividend behind the 512 and repeat the process: 5122 / 822

Moving on to step 6:
When dividing 5122 by 822, we get 6 with a remainder of 190.
Use 6 as the next digit of our solution. 
Result so far: 996.0
If we subtract 4932 from 5122, we get 190.
Append the next digit (8) from the dividend to 190 and continue with: 1908 / 822

Going ahead to step 7:
822 can be fit into 1908 2 times, resulting in a remainder of 264.
Record the quotient 2 as the next digit in the result. 
Result so far: 9962.0
Subtracting 1644 from 1908 leaves us with 264.
Include the next digit (5) from the dividend after 264, then repeat: 2645 / 822

Advancing to step 8:
822 can be fit into 2645 3 times, resulting in a remainder of 179.
The number 3 becomes the next digit in our result. 
Result so far: 99623.0
If we subtract 2466 from 2645, we get 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Let's proceed to step 9:
If we divide 1790 by 822, we get 2 and a remainder of 146.
Use 2 as the next digit of our solution. 
Result so far: 99623.2
Deduct 1644 from 1790 and we're left with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Advancing to step 10:
The number 822 fits into 1460 1 times, leaving a remainder of 638.
Put 1 as the next digit of the answer. 
Result so far: 99623.21
Subtract 822 from 1460 to get 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Moving on to step 11:
If we divide 6380 by 822, we get 7 and a remainder of 626.
Record the quotient 7 as the next digit in the result. 
Result so far: 99623.217
If we take 5754 away from 6380, we end up with 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Moving on to step 12:
822 goes into 6260 7 times with a remainder of 506.
Put 7 as the next digit of the answer. 
Result so far: 99623.2177
If we subtract 5754 from 6260, we get 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

The quotient of the division is 99623.2177, and the remainder is 0.00506.
