We're dividing 14378384 by 781 
The aim is to understand the frequency of 781 in 14378384.

Let's proceed to step 1:
1 divided by 781 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 781

Step 2:
If we divide 14 by 781, we get 0 and a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 781

Going ahead to step 3:
The number 781 fits into 143 0 times, leaving a remainder of 143.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 143, we end up with 143.
Take the next digit (7) from the dividend and append it to 143, then repeat: 1437 / 781

Moving on to step 4:
If we divide 1437 by 781, we get 1 and a remainder of 656.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 781 from 1437 and we're left with 656.
Include the next digit (8) from the dividend after 656, then repeat: 6568 / 781

Let's proceed to step 5:
6568 divided by 781 is 8 with a remainder of 320.
Use 8 as the next digit of our solution. 
Result so far: 18.0
If we subtract 6248 from 6568, we get 320.
Fetch the next digit (3) from the dividend, attach it to 320 and continue: 3203 / 781

On to step 6:
If we divide 3203 by 781, we get 4 and a remainder of 79.
The next digit of our result is 4. 
Result so far: 184.0
If we take 3124 away from 3203, we end up with 79.
Fetch the next digit (8) from the dividend, attach it to 79 and continue: 798 / 781

Advancing to step 7:
If we divide 798 by 781, we get 1 and a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 1841.0
The remainder is 17 after subtracting 781 from 798.
Include the next digit (4) from the dividend after 17, then repeat: 174 / 781

Advancing to step 8:
If we divide 174 by 781, we get 0 and a remainder of 174.
The next digit of our result is 0. 
Result so far: 18410.0
Subtracting 0 from 174 leaves us with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Step 9:
1740 divided by 781 is 2 with a remainder of 178.
The number 2 becomes the next digit in our result. 
Result so far: 18410.2
If we take 1562 away from 1740, we end up with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Step 10:
When dividing 1780 by 781, we get 2 with a remainder of 218.
Write down 2 as next digit of the result. 
Result so far: 18410.22
Subtracting 1562 from 1780 leaves us with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Our division results in 18410.22 with a remaining 0.218.
