30385154 ÷ 304 
The aim is to understand the frequency of 304 in 30385154.

Moving on to step 1:
304 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 304

On to step 2:
The number 304 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Append the next digit (3) from the dividend to 30 and continue with: 303 / 304

Advancing to step 3:
The number 304 fits into 303 0 times, leaving a remainder of 303.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 303 leaves us with 303.
Grab the next digit (8) from the dividend, add it to 303, then carry on: 3038 / 304

Going ahead to step 4:
The number 304 fits into 3038 9 times, leaving a remainder of 302.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 2736 from 3038 and we're left with 302.
Append the next digit (5) from the dividend to 302 and continue with: 3025 / 304

Advancing to step 5:
304 goes into 3025 9 times with a remainder of 289.
Write down 9 as next digit of the result. 
Result so far: 99.0
Subtract 2736 from 3025 to get 289.
Include the next digit (1) from the dividend after 289, then repeat: 2891 / 304

Let's proceed to step 6:
2891 divided by 304 is 9 with a remainder of 155.
Record the quotient 9 as the next digit in the result. 
Result so far: 999.0
If we subtract 2736 from 2891, we get 155.
Bring next digit (5) of the dividend behind the 155 and repeat the process: 1555 / 304

Moving on to step 7:
304 goes into 1555 5 times with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 9995.0
The remainder is 35 after subtracting 1520 from 1555.
Bring next digit (4) of the dividend behind the 35 and repeat the process: 354 / 304

Let's proceed to step 8:
When dividing 354 by 304, we get 1 with a remainder of 50.
Write down 1 as next digit of the result. 
Result so far: 99951.0
Deduct 304 from 354 and we're left with 50.
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 9:
500 divided by 304 is 1 with a remainder of 196.
The number 1 becomes the next digit in our result. 
Result so far: 99951.1
Deduct 304 from 500 and we're left with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Let's proceed to step 10:
The number 304 fits into 1960 6 times, leaving a remainder of 136.
Use 6 as the next digit of our solution. 
Result so far: 99951.16
Deduct 1824 from 1960 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Moving on to step 11:
1360 divided by 304 is 4 with a remainder of 144.
Use 4 as the next digit of our solution. 
Result so far: 99951.164
Deduct 1216 from 1360 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 12:
If we divide 1440 by 304, we get 4 and a remainder of 224.
Write down 4 as next digit of the result. 
Result so far: 99951.1644
If we subtract 1216 from 1440, we get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

The quotient of the division is 99951.1644, and the remainder is 0.00224.
