816502 ÷ 76 
The aim is to understand the frequency of 76 in 816502.

On to step 1:
8 divided by 76 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 76

Step 2:
76 can be fit into 81 1 times, resulting in a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 76 from 81 leaves us with 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 76

Advancing to step 3:
When dividing 56 by 76, we get 0 with a remainder of 56.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 56 to get 56.
Append the next digit (5) from the dividend to 56 and continue with: 565 / 76

Advancing to step 4:
565 divided by 76 is 7 with a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 107.0
Deduct 532 from 565 and we're left with 33.
Bring next digit (0) of the dividend behind the 33 and repeat the process: 330 / 76

On to step 5:
76 can be fit into 330 4 times, resulting in a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 1074.0
Subtracting 304 from 330 leaves us with 26.
Take the next digit (2) from the dividend and append it to 26, then repeat: 262 / 76

Step 6:
The number 76 fits into 262 3 times, leaving a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 10743.0
If we take 228 away from 262, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 7:
If we divide 340 by 76, we get 4 and a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 10743.4
Subtract 304 from 340 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 8:
The number 76 fits into 360 4 times, leaving a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 10743.44
Deduct 304 from 360 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The quotient of the division is 10743.44, and the remainder is 0.056.
