We look at the division of 11342215 by 823 
The aim is to understand the frequency of 823 in 11342215.

On to step 1:
When dividing 1 by 823, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 823

Moving on to step 2:
If we divide 11 by 823, we get 0 and a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 11, we get 11.
Bring next digit (3) of the dividend behind the 11 and repeat the process: 113 / 823

Going ahead to step 3:
113 divided by 823 is 0 with a remainder of 113.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 113 and we're left with 113.
Include the next digit (4) from the dividend after 113, then repeat: 1134 / 823

Advancing to step 4:
823 goes into 1134 1 times with a remainder of 311.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 823 from 1134 leaves us with 311.
Append the next digit (2) from the dividend to 311 and continue with: 3112 / 823

On to step 5:
If we divide 3112 by 823, we get 3 and a remainder of 643.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 643 after subtracting 2469 from 3112.
Take the next digit (2) from the dividend and append it to 643, then repeat: 6432 / 823

Advancing to step 6:
823 can be fit into 6432 7 times, resulting in a remainder of 671.
Use 7 as the next digit of our solution. 
Result so far: 137.0
Subtract 5761 from 6432 to get 671.
Take the next digit (1) from the dividend and append it to 671, then repeat: 6711 / 823

Going ahead to step 7:
When dividing 6711 by 823, we get 8 with a remainder of 127.
Record the quotient 8 as the next digit in the result. 
Result so far: 1378.0
Subtract 6584 from 6711 to get 127.
Grab the next digit (5) from the dividend, add it to 127, then carry on: 1275 / 823

Step 8:
The number 823 fits into 1275 1 times, leaving a remainder of 452.
The next digit of our result is 1. 
Result so far: 13781.0
If we take 823 away from 1275, we end up with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

On to step 9:
823 can be fit into 4520 5 times, resulting in a remainder of 405.
The number 5 becomes the next digit in our result. 
Result so far: 13781.5
If we take 4115 away from 4520, we end up with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Let's proceed to step 10:
When dividing 4050 by 823, we get 4 with a remainder of 758.
The number 4 becomes the next digit in our result. 
Result so far: 13781.54
If we take 3292 away from 4050, we end up with 758.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7580, and continue the process.

On to step 11:
If we divide 7580 by 823, we get 9 and a remainder of 173.
Write down 9 as next digit of the result. 
Result so far: 13781.549
Subtract 7407 from 7580 to get 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Going ahead to step 12:
If we divide 1730 by 823, we get 2 and a remainder of 84.
Use 2 as the next digit of our solution. 
Result so far: 13781.5492
The remainder is 84 after subtracting 1646 from 1730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 13:
The number 823 fits into 840 1 times, leaving a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 13781.54921
Deduct 823 from 840 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 14:
If we divide 170 by 823, we get 0 and a remainder of 170.
Record the quotient 0 as the next digit in the result. 
Result so far: 13781.54921
The remainder is 170 after subtracting 0 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 15:
1700 divided by 823 is 2 with a remainder of 54.
The next digit of our result is 2. 
Result so far: 13781.5492102
Deduct 1646 from 1700 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 16:
540 divided by 823 is 0 with a remainder of 540.
The number 0 becomes the next digit in our result. 
Result so far: 13781.5492102
Subtract 0 from 540 to get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Our division results in 13781.5492102 with a remaining 5.4e-07.
