815300 ÷ 74 
The aim is to understand the frequency of 74 in 815300.

Step 1:
When dividing 8 by 74, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 74

Step 2:
When dividing 81 by 74, we get 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 74 from 81 leaves us with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 74

Let's proceed to step 3:
The number 74 fits into 75 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 1 after subtracting 74 from 75.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 74

Step 4:
The number 74 fits into 13 0 times, leaving a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 110.0
Subtracting 0 from 13 leaves us with 13.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 74

Step 5:
74 can be fit into 130 1 times, resulting in a remainder of 56.
Record the quotient 1 as the next digit in the result. 
Result so far: 1101.0
If we take 74 away from 130, we end up with 56.
Bring next digit (0) of the dividend behind the 56 and repeat the process: 560 / 74

Going ahead to step 6:
The number 74 fits into 560 7 times, leaving a remainder of 42.
Put 7 as the next digit of the answer. 
Result so far: 11017.0
Subtracting 518 from 560 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 7:
The number 74 fits into 420 5 times, leaving a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 11017.5
The remainder is 50 after subtracting 370 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
If we divide 500 by 74, we get 6 and a remainder of 56.
Put 6 as the next digit of the answer. 
Result so far: 11017.56
Subtracting 444 from 500 leaves us 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.

Advancing to step 9:
When dividing 560 by 74, we get 7 with a remainder of 42.
Record the quotient 7 as the next digit in the result. 
Result so far: 11017.567
The remainder is 42 after subtracting 518 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 10:
420 divided by 74 is 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 11017.5675
Subtract 370 from 420 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 11:
500 divided by 74 is 6 with a remainder of 56.
Record the quotient 6 as the next digit in the result. 
Result so far: 11017.56756
If we subtract 444 from 500, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 12:
74 goes into 560 7 times with a remainder of 42.
Write down 7 as next digit of the result. 
Result so far: 11017.567567
If we take 518 away from 560, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 13:
74 goes into 420 5 times with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 11017.5675675
If we subtract 370 from 420, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 14:
If we divide 500 by 74, we get 6 and a remainder of 56.
The number 6 becomes the next digit in our result. 
Result so far: 11017.56756756
The remainder is 56 after subtracting 444 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

In conclusion, the division gives 11017.56756756 with a balance of 5.6e-08.
