90581031 ÷ 822 
The aim is to understand the frequency of 822 in 90581031.

On to step 1:
822 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 822

Step 2:
If we divide 90 by 822, we get 0 and a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Include the next digit (5) from the dividend after 90, then repeat: 905 / 822

Step 3:
822 can be fit into 905 1 times, resulting in a remainder of 83.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 822 from 905 to get 83.
Take the next digit (8) from the dividend and append it to 83, then repeat: 838 / 822

Moving on to step 4:
822 can be fit into 838 1 times, resulting in a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 822 from 838 and we're left with 16.
Take the next digit (1) from the dividend and append it to 16, then repeat: 161 / 822

Step 5:
When dividing 161 by 822, we get 0 with a remainder of 161.
Record the quotient 0 as the next digit in the result. 
Result so far: 110.0
Subtract 0 from 161 to get 161.
Bring next digit (0) of the dividend behind the 161 and repeat the process: 1610 / 822

Going ahead to step 6:
When dividing 1610 by 822, we get 1 with a remainder of 788.
Record the quotient 1 as the next digit in the result. 
Result so far: 1101.0
The remainder is 788 after subtracting 822 from 1610.
Grab the next digit (3) from the dividend, add it to 788, then carry on: 7883 / 822

On to step 7:
When dividing 7883 by 822, we get 9 with a remainder of 485.
Put 9 as the next digit of the answer. 
Result so far: 11019.0
The remainder is 485 after subtracting 7398 from 7883.
Fetch the next digit (1) from the dividend, attach it to 485 and continue: 4851 / 822

Moving on to step 8:
822 can be fit into 4851 5 times, resulting in a remainder of 741.
Use 5 as the next digit of our solution. 
Result so far: 110195.0
If we take 4110 away from 4851, we end up with 741.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7410, and continue the process.

Let's proceed to step 9:
7410 divided by 822 is 9 with a remainder of 12.
The next digit of our result is 9. 
Result so far: 110195.9
If we take 7398 away from 7410, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
822 can be fit into 120 0 times, resulting in a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 110195.9
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 11:
The number 822 fits into 1200 1 times, leaving a remainder of 378.
Use 1 as the next digit of our solution. 
Result so far: 110195.901
The remainder is 378 after subtracting 822 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Going ahead to step 12:
If we divide 3780 by 822, we get 4 and a remainder of 492.
The number 4 becomes the next digit in our result. 
Result so far: 110195.9014
Subtract 3288 from 3780 to get 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Step 13:
4920 divided by 822 is 5 with a remainder of 810.
The next digit of our result is 5. 
Result so far: 110195.90145
Subtract 4110 from 4920 to get 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

Moving on to step 14:
822 can be fit into 8100 9 times, resulting in a remainder of 702.
The number 9 becomes the next digit in our result. 
Result so far: 110195.901459
Subtract 7398 from 8100 to get 702.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7020, and continue the process.

Advancing to step 15:
When dividing 7020 by 822, we get 8 with a remainder of 444.
Write down 8 as next digit of the result. 
Result so far: 110195.9014598
If we take 6576 away from 7020, we end up with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Going ahead to step 16:
822 can be fit into 4440 5 times, resulting in a remainder of 330.
Write down 5 as next digit of the result. 
Result so far: 110195.90145985
Subtracting 4110 from 4440 leaves us with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

The final result is 110195.90145985 with a remainder of 3.3e-07.
