We divide 16320019 by 823
The aim is to understand the frequency of 823 in 16320019.

Step 1:
823 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 823

Moving on to step 2:
16 divided by 823 is 0 with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 823

On to step 3:
823 can be fit into 163 0 times, resulting in a remainder of 163.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 163, we get 163.
Append the next digit (2) from the dividend to 163 and continue with: 1632 / 823

Let's proceed to step 4:
The number 823 fits into 1632 1 times, leaving a remainder of 809.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 823 from 1632, we get 809.
Fetch the next digit (0) from the dividend, attach it to 809 and continue: 8090 / 823

Going ahead to step 5:
The number 823 fits into 8090 9 times, leaving a remainder of 683.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtract 7407 from 8090 to get 683.
Take the next digit (0) from the dividend and append it to 683, then repeat: 6830 / 823

Let's proceed to step 6:
6830 divided by 823 is 8 with a remainder of 246.
Use 8 as the next digit of our solution. 
Result so far: 198.0
If we subtract 6584 from 6830, we get 246.
Grab the next digit (1) from the dividend, add it to 246, then carry on: 2461 / 823

On to step 7:
823 can be fit into 2461 2 times, resulting in a remainder of 815.
Use 2 as the next digit of our solution. 
Result so far: 1982.0
If we take 1646 away from 2461, we end up with 815.
Bring next digit (9) of the dividend behind the 815 and repeat the process: 8159 / 823

Going ahead to step 8:
If we divide 8159 by 823, we get 9 and a remainder of 752.
Use 9 as the next digit of our solution. 
Result so far: 19829.0
The remainder is 752 after subtracting 7407 from 8159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

Advancing to step 9:
The number 823 fits into 7520 9 times, leaving a remainder of 113.
Put 9 as the next digit of the answer. 
Result so far: 19829.9
Deduct 7407 from 7520 and we're left with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Moving on to step 10:
1130 divided by 823 is 1 with a remainder of 307.
Put 1 as the next digit of the answer. 
Result so far: 19829.91
Subtracting 823 from 1130 leaves us with 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Step 11:
The number 823 fits into 3070 3 times, leaving a remainder of 601.
Write down 3 as next digit of the result. 
Result so far: 19829.913
Subtract 2469 from 3070 to get 601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6010, and continue the process.

Let's proceed to step 12:
823 goes into 6010 7 times with a remainder of 249.
Write down 7 as next digit of the result. 
Result so far: 19829.9137
Subtracting 5761 from 6010 leaves us with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

On to step 13:
823 goes into 2490 3 times with a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 19829.91373
If we subtract 2469 from 2490, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 14:
823 goes into 210 0 times with a remainder of 210.
Record the quotient 0 as the next digit in the result. 
Result so far: 19829.91373
If we subtract 0 from 210, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 15:
If we divide 2100 by 823, we get 2 and a remainder of 454.
Record the quotient 2 as the next digit in the result. 
Result so far: 19829.9137302
Deduct 1646 from 2100 and we're left with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Step 16:
If we divide 4540 by 823, we get 5 and a remainder of 425.
The number 5 becomes the next digit in our result. 
Result so far: 19829.91373025
Subtracting 4115 from 4540 leaves us with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Our division results in 19829.91373025 with a remaining 4.25e-07.
