We look at the division of 76064382 by 821 
The aim is to understand the frequency of 821 in 76064382.

Moving on to step 1:
7 divided by 821 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 821

On to step 2:
If we divide 76 by 821, we get 0 and a remainder of 76.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 76 to get 76.
Take the next digit (0) from the dividend and append it to 76, then repeat: 760 / 821

Step 3:
If we divide 760 by 821, we get 0 and a remainder of 760.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 760, we get 760.
Bring next digit (6) of the dividend behind the 760 and repeat the process: 7606 / 821

Moving on to step 4:
If we divide 7606 by 821, we get 9 and a remainder of 217.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 7389 from 7606 leaves us with 217.
Bring next digit (4) of the dividend behind the 217 and repeat the process: 2174 / 821

Going ahead to step 5:
When dividing 2174 by 821, we get 2 with a remainder of 532.
Record the quotient 2 as the next digit in the result. 
Result so far: 92.0
If we subtract 1642 from 2174, we get 532.
Include the next digit (3) from the dividend after 532, then repeat: 5323 / 821

Let's proceed to step 6:
5323 divided by 821 is 6 with a remainder of 397.
Use 6 as the next digit of our solution. 
Result so far: 926.0
If we subtract 4926 from 5323, we get 397.
Grab the next digit (8) from the dividend, add it to 397, then carry on: 3978 / 821

Let's proceed to step 7:
821 can be fit into 3978 4 times, resulting in a remainder of 694.
Use 4 as the next digit of our solution. 
Result so far: 9264.0
Subtract 3284 from 3978 to get 694.
Append the next digit (2) from the dividend to 694 and continue with: 6942 / 821

Let's proceed to step 8:
The number 821 fits into 6942 8 times, leaving a remainder of 374.
Use 8 as the next digit of our solution. 
Result so far: 92648.0
Subtracting 6568 from 6942 leaves us with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

On to step 9:
If we divide 3740 by 821, we get 4 and a remainder of 456.
Write down 4 as next digit of the result. 
Result so far: 92648.4
If we take 3284 away from 3740, we end up with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Advancing to step 10:
821 can be fit into 4560 5 times, resulting in a remainder of 455.
Put 5 as the next digit of the answer. 
Result so far: 92648.45
Subtracting 4105 from 4560 leaves us with 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Let's proceed to step 11:
The number 821 fits into 4550 5 times, leaving a remainder of 445.
Write down 5 as next digit of the result. 
Result so far: 92648.455
Subtract 4105 from 4550 to get 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

In conclusion, the division gives 92648.455 with a balance of 0.0445.
