We look at the division of 18455549 by 781 
We want to divide 18455549 by 781.

Going ahead to step 1:
781 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 781

Step 2:
781 goes into 18 0 times with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Append the next digit (4) from the dividend to 18 and continue with: 184 / 781

Going ahead to step 3:
The number 781 fits into 184 0 times, leaving a remainder of 184.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 184, we end up with 184.
Grab the next digit (5) from the dividend, add it to 184, then carry on: 1845 / 781

Step 4:
781 goes into 1845 2 times with a remainder of 283.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 1562 from 1845 and we're left with 283.
Append the next digit (5) from the dividend to 283 and continue with: 2835 / 781

Moving on to step 5:
781 can be fit into 2835 3 times, resulting in a remainder of 492.
Put 3 as the next digit of the answer. 
Result so far: 23.0
If we subtract 2343 from 2835, we get 492.
Bring next digit (5) of the dividend behind the 492 and repeat the process: 4925 / 781

Let's proceed to step 6:
The number 781 fits into 4925 6 times, leaving a remainder of 239.
Use 6 as the next digit of our solution. 
Result so far: 236.0
The remainder is 239 after subtracting 4686 from 4925.
Append the next digit (4) from the dividend to 239 and continue with: 2394 / 781

Advancing to step 7:
781 can be fit into 2394 3 times, resulting in a remainder of 51.
Use 3 as the next digit of our solution. 
Result so far: 2363.0
Deduct 2343 from 2394 and we're left with 51.
Grab the next digit (9) from the dividend, add it to 51, then carry on: 519 / 781

Let's proceed to step 8:
781 goes into 519 0 times with a remainder of 519.
The number 0 becomes the next digit in our result. 
Result so far: 23630.0
The remainder is 519 after subtracting 0 from 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

Going ahead to step 9:
781 can be fit into 5190 6 times, resulting in a remainder of 504.
Record the quotient 6 as the next digit in the result. 
Result so far: 23630.6
The remainder is 504 after subtracting 4686 from 5190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Advancing to step 10:
The number 781 fits into 5040 6 times, leaving a remainder of 354.
Put 6 as the next digit of the answer. 
Result so far: 23630.66
Subtract 4686 from 5040 to get 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Our division results in 23630.66 with a remaining 0.354.
