We look at the division of 56588316 by 823 
The aim is to understand the frequency of 823 in 56588316.

On to step 1:
823 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 823

Advancing to step 2:
The number 823 fits into 56 0 times, leaving a remainder of 56.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 56 after subtracting 0 from 56.
Fetch the next digit (5) from the dividend, attach it to 56 and continue: 565 / 823

Going ahead to step 3:
823 can be fit into 565 0 times, resulting in a remainder of 565.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 565 after subtracting 0 from 565.
Include the next digit (8) from the dividend after 565, then repeat: 5658 / 823

Step 4:
If we divide 5658 by 823, we get 6 and a remainder of 720.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 4938 from 5658 and we're left with 720.
Include the next digit (8) from the dividend after 720, then repeat: 7208 / 823

Advancing to step 5:
If we divide 7208 by 823, we get 8 and a remainder of 624.
The number 8 becomes the next digit in our result. 
Result so far: 68.0
Subtracting 6584 from 7208 leaves us with 624.
Bring next digit (3) of the dividend behind the 624 and repeat the process: 6243 / 823

On to step 6:
823 goes into 6243 7 times with a remainder of 482.
Record the quotient 7 as the next digit in the result. 
Result so far: 687.0
The remainder is 482 after subtracting 5761 from 6243.
Grab the next digit (1) from the dividend, add it to 482, then carry on: 4821 / 823

Moving on to step 7:
When dividing 4821 by 823, we get 5 with a remainder of 706.
Put 5 as the next digit of the answer. 
Result so far: 6875.0
The remainder is 706 after subtracting 4115 from 4821.
Append the next digit (6) from the dividend to 706 and continue with: 7066 / 823

Advancing to step 8:
823 goes into 7066 8 times with a remainder of 482.
Use 8 as the next digit of our solution. 
Result so far: 68758.0
The remainder is 482 after subtracting 6584 from 7066.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Let's proceed to step 9:
When dividing 4820 by 823, we get 5 with a remainder of 705.
Write down 5 as next digit of the result. 
Result so far: 68758.5
Subtracting 4115 from 4820 leaves us with 705.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7050, and continue the process.

On to step 10:
If we divide 7050 by 823, we get 8 and a remainder of 466.
The next digit of our result is 8. 
Result so far: 68758.58
Subtract 6584 from 7050 to get 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Going ahead to step 11:
823 can be fit into 4660 5 times, resulting in a remainder of 545.
Record the quotient 5 as the next digit in the result. 
Result so far: 68758.585
Subtract 4115 from 4660 to get 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Step 12:
When dividing 5450 by 823, we get 6 with a remainder of 512.
Record the quotient 6 as the next digit in the result. 
Result so far: 68758.5856
If we take 4938 away from 5450, we end up with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Going ahead to step 13:
5120 divided by 823 is 6 with a remainder of 182.
Write down 6 as next digit of the result. 
Result so far: 68758.58566
If we subtract 4938 from 5120, we get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

The final result is 68758.58566 with a remainder of 0.000182.
