We look at the division of 30484034 by 783 
The aim is to understand the frequency of 783 in 30484034.

On to step 1:
When dividing 3 by 783, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 783

Going ahead to step 2:
The number 783 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Bring next digit (4) of the dividend behind the 30 and repeat the process: 304 / 783

Advancing to step 3:
783 can be fit into 304 0 times, resulting in a remainder of 304.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 304 to get 304.
Append the next digit (8) from the dividend to 304 and continue with: 3048 / 783

Going ahead to step 4:
When dividing 3048 by 783, we get 3 with a remainder of 699.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 2349 from 3048 to get 699.
Append the next digit (4) from the dividend to 699 and continue with: 6994 / 783

On to step 5:
If we divide 6994 by 783, we get 8 and a remainder of 730.
Write down 8 as next digit of the result. 
Result so far: 38.0
If we take 6264 away from 6994, we end up with 730.
Bring next digit (0) of the dividend behind the 730 and repeat the process: 7300 / 783

Let's proceed to step 6:
783 can be fit into 7300 9 times, resulting in a remainder of 253.
Write down 9 as next digit of the result. 
Result so far: 389.0
The remainder is 253 after subtracting 7047 from 7300.
Fetch the next digit (3) from the dividend, attach it to 253 and continue: 2533 / 783

Let's proceed to step 7:
The number 783 fits into 2533 3 times, leaving a remainder of 184.
Record the quotient 3 as the next digit in the result. 
Result so far: 3893.0
Subtracting 2349 from 2533 leaves us with 184.
Fetch the next digit (4) from the dividend, attach it to 184 and continue: 1844 / 783

Moving on to step 8:
1844 divided by 783 is 2 with a remainder of 278.
The number 2 becomes the next digit in our result. 
Result so far: 38932.0
Deduct 1566 from 1844 and we're left with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Let's proceed to step 9:
When dividing 2780 by 783, we get 3 with a remainder of 431.
Use 3 as the next digit of our solution. 
Result so far: 38932.3
If we subtract 2349 from 2780, we get 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

On to step 10:
The number 783 fits into 4310 5 times, leaving a remainder of 395.
Write down 5 as next digit of the result. 
Result so far: 38932.35
Subtracting 3915 from 4310 leaves us with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Step 11:
3950 divided by 783 is 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 38932.355
If we subtract 3915 from 3950, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The quotient of the division is 38932.355, and the remainder is 0.0035.
