We look at the division of 76352216 by 820 
The aim is to understand the frequency of 820 in 76352216.

Step 1:
820 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 820

Moving on to step 2:
The number 820 fits into 76 0 times, leaving a remainder of 76.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 76 leaves us with 76.
Take the next digit (3) from the dividend and append it to 76, then repeat: 763 / 820

On to step 3:
The number 820 fits into 763 0 times, leaving a remainder of 763.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 763, we get 763.
Bring next digit (5) of the dividend behind the 763 and repeat the process: 7635 / 820

Step 4:
When dividing 7635 by 820, we get 9 with a remainder of 255.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 7380 from 7635, we get 255.
Fetch the next digit (2) from the dividend, attach it to 255 and continue: 2552 / 820

Step 5:
820 goes into 2552 3 times with a remainder of 92.
The number 3 becomes the next digit in our result. 
Result so far: 93.0
Deduct 2460 from 2552 and we're left with 92.
Bring next digit (2) of the dividend behind the 92 and repeat the process: 922 / 820

Advancing to step 6:
When dividing 922 by 820, we get 1 with a remainder of 102.
Put 1 as the next digit of the answer. 
Result so far: 931.0
Subtract 820 from 922 to get 102.
Take the next digit (1) from the dividend and append it to 102, then repeat: 1021 / 820

Let's proceed to step 7:
The number 820 fits into 1021 1 times, leaving a remainder of 201.
Write down 1 as next digit of the result. 
Result so far: 9311.0
Deduct 820 from 1021 and we're left with 201.
Take the next digit (6) from the dividend and append it to 201, then repeat: 2016 / 820

Step 8:
820 goes into 2016 2 times with a remainder of 376.
Record the quotient 2 as the next digit in the result. 
Result so far: 93112.0
The remainder is 376 after subtracting 1640 from 2016.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

On to step 9:
820 can be fit into 3760 4 times, resulting in a remainder of 480.
Record the quotient 4 as the next digit in the result. 
Result so far: 93112.4
Subtracting 3280 from 3760 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 10:
If we divide 4800 by 820, we get 5 and a remainder of 700.
Write down 5 as next digit of the result. 
Result so far: 93112.45
If we take 4100 away from 4800, we end up with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Going ahead to step 11:
If we divide 7000 by 820, we get 8 and a remainder of 440.
Write down 8 as next digit of the result. 
Result so far: 93112.458
Deduct 6560 from 7000 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Step 12:
If we divide 4400 by 820, we get 5 and a remainder of 300.
Put 5 as the next digit of the answer. 
Result so far: 93112.4585
Subtract 4100 from 4400 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 13:
820 can be fit into 3000 3 times, resulting in a remainder of 540.
Use 3 as the next digit of our solution. 
Result so far: 93112.45853
The remainder is 540 after subtracting 2460 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Let's proceed to step 14:
If we divide 5400 by 820, we get 6 and a remainder of 480.
Put 6 as the next digit of the answer. 
Result so far: 93112.458536
If we subtract 4920 from 5400, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 15:
4800 divided by 820 is 5 with a remainder of 700.
The next digit of our result is 5. 
Result so far: 93112.4585365
Deduct 4100 from 4800 and we're left with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Advancing to step 16:
820 goes into 7000 8 times with a remainder of 440.
Put 8 as the next digit of the answer. 
Result so far: 93112.45853658
The remainder is 440 after subtracting 6560 from 7000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Our division results in 93112.45853658 with a remaining 4.4e-07.
