We look at the division of 1868435 by 823 
The aim is to understand the frequency of 823 in 1868435.

Moving on to step 1:
If we divide 1 by 823, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 823

Let's proceed to step 2:
823 can be fit into 18 0 times, resulting in a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 823

Advancing to step 3:
823 can be fit into 186 0 times, resulting in a remainder of 186.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 186 and we're left with 186.
Grab the next digit (8) from the dividend, add it to 186, then carry on: 1868 / 823

Going ahead to step 4:
1868 divided by 823 is 2 with a remainder of 222.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 1646 from 1868, we get 222.
Bring next digit (4) of the dividend behind the 222 and repeat the process: 2224 / 823

Going ahead to step 5:
The number 823 fits into 2224 2 times, leaving a remainder of 578.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Subtracting 1646 from 2224 leaves us with 578.
Take the next digit (3) from the dividend and append it to 578, then repeat: 5783 / 823

Advancing to step 6:
823 goes into 5783 7 times with a remainder of 22.
The next digit of our result is 7. 
Result so far: 227.0
Subtract 5761 from 5783 to get 22.
Append the next digit (5) from the dividend to 22 and continue with: 225 / 823

On to step 7:
If we divide 225 by 823, we get 0 and a remainder of 225.
Use 0 as the next digit of our solution. 
Result so far: 2270.0
If we subtract 0 from 225, we get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Step 8:
If we divide 2250 by 823, we get 2 and a remainder of 604.
The number 2 becomes the next digit in our result. 
Result so far: 2270.2
The remainder is 604 after subtracting 1646 from 2250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Advancing to step 9:
The number 823 fits into 6040 7 times, leaving a remainder of 279.
Use 7 as the next digit of our solution. 
Result so far: 2270.27
The remainder is 279 after subtracting 5761 from 6040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Moving on to step 10:
If we divide 2790 by 823, we get 3 and a remainder of 321.
Use 3 as the next digit of our solution. 
Result so far: 2270.273
Subtract 2469 from 2790 to get 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Moving on to step 11:
The number 823 fits into 3210 3 times, leaving a remainder of 741.
Record the quotient 3 as the next digit in the result. 
Result so far: 2270.2733
Subtract 2469 from 3210 to get 741.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7410, and continue the process.

The quotient of the division is 2270.2733, and the remainder is 0.00741.
