97424319 ÷ 820 
The aim is to understand the frequency of 820 in 97424319.

Step 1:
820 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 820

Step 2:
The number 820 fits into 97 0 times, leaving a remainder of 97.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 97 and we're left with 97.
Append the next digit (4) from the dividend to 97 and continue with: 974 / 820

On to step 3:
The number 820 fits into 974 1 times, leaving a remainder of 154.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 820 from 974, we get 154.
Bring next digit (2) of the dividend behind the 154 and repeat the process: 1542 / 820

Advancing to step 4:
The number 820 fits into 1542 1 times, leaving a remainder of 722.
The next digit of our result is 1. 
Result so far: 11.0
Deduct 820 from 1542 and we're left with 722.
Bring next digit (4) of the dividend behind the 722 and repeat the process: 7224 / 820

On to step 5:
7224 divided by 820 is 8 with a remainder of 664.
Record the quotient 8 as the next digit in the result. 
Result so far: 118.0
Deduct 6560 from 7224 and we're left with 664.
Take the next digit (3) from the dividend and append it to 664, then repeat: 6643 / 820

Moving on to step 6:
When dividing 6643 by 820, we get 8 with a remainder of 83.
The number 8 becomes the next digit in our result. 
Result so far: 1188.0
If we take 6560 away from 6643, we end up with 83.
Take the next digit (1) from the dividend and append it to 83, then repeat: 831 / 820

Moving on to step 7:
820 goes into 831 1 times with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 11881.0
If we take 820 away from 831, we end up with 11.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 820

Step 8:
The number 820 fits into 119 0 times, leaving a remainder of 119.
Use 0 as the next digit of our solution. 
Result so far: 118810.0
If we subtract 0 from 119, we get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Let's proceed to step 9:
820 can be fit into 1190 1 times, resulting in a remainder of 370.
Write down 1 as next digit of the result. 
Result so far: 118810.1
The remainder is 370 after subtracting 820 from 1190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 10:
820 goes into 3700 4 times with a remainder of 420.
Write down 4 as next digit of the result. 
Result so far: 118810.14
The remainder is 420 after subtracting 3280 from 3700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

On to step 11:
820 can be fit into 4200 5 times, resulting in a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 118810.145
If we take 4100 away from 4200, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 12:
The number 820 fits into 1000 1 times, leaving a remainder of 180.
The number 1 becomes the next digit in our result. 
Result so far: 118810.1451
If we take 820 away from 1000, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 13:
If we divide 1800 by 820, we get 2 and a remainder of 160.
The next digit of our result is 2. 
Result so far: 118810.14512
If we subtract 1640 from 1800, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 14:
When dividing 1600 by 820, we get 1 with a remainder of 780.
The next digit of our result is 1. 
Result so far: 118810.145121
The remainder is 780 after subtracting 820 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Step 15:
820 can be fit into 7800 9 times, resulting in a remainder of 420.
Use 9 as the next digit of our solution. 
Result so far: 118810.1451219
If we take 7380 away from 7800, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Going ahead to step 16:
820 goes into 4200 5 times with a remainder of 100.
Put 5 as the next digit of the answer. 
Result so far: 118810.14512195
If we take 4100 away from 4200, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 118810.14512195 with a remainder of 1e-07.
