We're dividing 79620015 by 820 
The aim is to understand the frequency of 820 in 79620015.

Moving on to step 1:
820 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 820

Step 2:
79 divided by 820 is 0 with a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 79, we get 79.
Fetch the next digit (6) from the dividend, attach it to 79 and continue: 796 / 820

Moving on to step 3:
When dividing 796 by 820, we get 0 with a remainder of 796.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 796 to get 796.
Fetch the next digit (2) from the dividend, attach it to 796 and continue: 7962 / 820

Moving on to step 4:
If we divide 7962 by 820, we get 9 and a remainder of 582.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 7380 from 7962 and we're left with 582.
Bring next digit (0) of the dividend behind the 582 and repeat the process: 5820 / 820

On to step 5:
820 can be fit into 5820 7 times, resulting in a remainder of 80.
Put 7 as the next digit of the answer. 
Result so far: 97.0
Subtracting 5740 from 5820 leaves us with 80.
Fetch the next digit (0) from the dividend, attach it to 80 and continue: 800 / 820

Let's proceed to step 6:
When dividing 800 by 820, we get 0 with a remainder of 800.
Record the quotient 0 as the next digit in the result. 
Result so far: 970.0
The remainder is 800 after subtracting 0 from 800.
Grab the next digit (1) from the dividend, add it to 800, then carry on: 8001 / 820

Step 7:
When dividing 8001 by 820, we get 9 with a remainder of 621.
Put 9 as the next digit of the answer. 
Result so far: 9709.0
Subtract 7380 from 8001 to get 621.
Bring next digit (5) of the dividend behind the 621 and repeat the process: 6215 / 820

Step 8:
820 goes into 6215 7 times with a remainder of 475.
The next digit of our result is 7. 
Result so far: 97097.0
If we subtract 5740 from 6215, we get 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Let's proceed to step 9:
820 can be fit into 4750 5 times, resulting in a remainder of 650.
Record the quotient 5 as the next digit in the result. 
Result so far: 97097.5
Deduct 4100 from 4750 and we're left with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

On to step 10:
If we divide 6500 by 820, we get 7 and a remainder of 760.
Write down 7 as next digit of the result. 
Result so far: 97097.57
If we take 5740 away from 6500, we end up with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Going ahead to step 11:
If we divide 7600 by 820, we get 9 and a remainder of 220.
Write down 9 as next digit of the result. 
Result so far: 97097.579
The remainder is 220 after subtracting 7380 from 7600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 12:
When dividing 2200 by 820, we get 2 with a remainder of 560.
Put 2 as the next digit of the answer. 
Result so far: 97097.5792
If we subtract 1640 from 2200, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Moving on to step 13:
820 can be fit into 5600 6 times, resulting in a remainder of 680.
The number 6 becomes the next digit in our result. 
Result so far: 97097.57926
Subtract 4920 from 5600 to get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Step 14:
When dividing 6800 by 820, we get 8 with a remainder of 240.
The number 8 becomes the next digit in our result. 
Result so far: 97097.579268
Subtract 6560 from 6800 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 15:
2400 divided by 820 is 2 with a remainder of 760.
The number 2 becomes the next digit in our result. 
Result so far: 97097.5792682
The remainder is 760 after subtracting 1640 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Going ahead to step 16:
The number 820 fits into 7600 9 times, leaving a remainder of 220.
Record the quotient 9 as the next digit in the result. 
Result so far: 97097.57926829
Subtract 7380 from 7600 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

The final result is 97097.57926829 with a remainder of 2.2e-07.
