80602501 ÷ 823 
The aim is to understand the frequency of 823 in 80602501.

Step 1:
823 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 823

Moving on to step 2:
823 can be fit into 80 0 times, resulting in a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Bring next digit (6) of the dividend behind the 80 and repeat the process: 806 / 823

Moving on to step 3:
When dividing 806 by 823, we get 0 with a remainder of 806.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 806 and we're left with 806.
Include the next digit (0) from the dividend after 806, then repeat: 8060 / 823

Let's proceed to step 4:
8060 divided by 823 is 9 with a remainder of 653.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 7407 from 8060 and we're left with 653.
Take the next digit (2) from the dividend and append it to 653, then repeat: 6532 / 823

Advancing to step 5:
823 goes into 6532 7 times with a remainder of 771.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
Subtract 5761 from 6532 to get 771.
Bring next digit (5) of the dividend behind the 771 and repeat the process: 7715 / 823

Moving on to step 6:
When dividing 7715 by 823, we get 9 with a remainder of 308.
Use 9 as the next digit of our solution. 
Result so far: 979.0
The remainder is 308 after subtracting 7407 from 7715.
Append the next digit (0) from the dividend to 308 and continue with: 3080 / 823

Let's proceed to step 7:
If we divide 3080 by 823, we get 3 and a remainder of 611.
Write down 3 as next digit of the result. 
Result so far: 9793.0
Subtract 2469 from 3080 to get 611.
Include the next digit (1) from the dividend after 611, then repeat: 6111 / 823

Moving on to step 8:
823 goes into 6111 7 times with a remainder of 350.
The next digit of our result is 7. 
Result so far: 97937.0
If we subtract 5761 from 6111, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 9:
When dividing 3500 by 823, we get 4 with a remainder of 208.
Write down 4 as next digit of the result. 
Result so far: 97937.4
The remainder is 208 after subtracting 3292 from 3500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Let's proceed to step 10:
If we divide 2080 by 823, we get 2 and a remainder of 434.
Write down 2 as next digit of the result. 
Result so far: 97937.42
Subtracting 1646 from 2080 leaves us with 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Advancing to step 11:
823 can be fit into 4340 5 times, resulting in a remainder of 225.
Put 5 as the next digit of the answer. 
Result so far: 97937.425
Subtract 4115 from 4340 to 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.

Advancing to step 12:
If we divide 2250 by 823, we get 2 and a remainder of 604.
Record the quotient 2 as the next digit in the result. 
Result so far: 97937.4252
Deduct 1646 from 2250 and we're left with 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Moving on to step 13:
When dividing 6040 by 823, we get 7 with a remainder of 279.
Write down 7 as next digit of the result. 
Result so far: 97937.42527
Subtract 5761 from 6040 to get 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Let's proceed to step 14:
When dividing 2790 by 823, we get 3 with a remainder of 321.
Record the quotient 3 as the next digit in the result. 
Result so far: 97937.425273
If we take 2469 away from 2790, we end up with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Going ahead to step 15:
3210 divided by 823 is 3 with a remainder of 741.
The number 3 becomes the next digit in our result. 
Result so far: 97937.4252733
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 97937.4252733, and the remainder is 7.41e-06.
