We look at the division of 81994240 by 781 
We want to divide 81994240 by 781.

Let's proceed to step 1:
781 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 781

Let's proceed to step 2:
81 divided by 781 is 0 with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Include the next digit (9) from the dividend after 81, then repeat: 819 / 781

Step 3:
The number 781 fits into 819 1 times, leaving a remainder of 38.
The next digit of our result is 1. 
Result so far: 1.0
If we take 781 away from 819, we end up with 38.
Grab the next digit (9) from the dividend, add it to 38, then carry on: 389 / 781

Step 4:
The number 781 fits into 389 0 times, leaving a remainder of 389.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 389 to get 389.
Take the next digit (4) from the dividend and append it to 389, then repeat: 3894 / 781

Going ahead to step 5:
The number 781 fits into 3894 4 times, leaving a remainder of 770.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
The remainder is 770 after subtracting 3124 from 3894.
Fetch the next digit (2) from the dividend, attach it to 770 and continue: 7702 / 781

Going ahead to step 6:
The number 781 fits into 7702 9 times, leaving a remainder of 673.
Put 9 as the next digit of the answer. 
Result so far: 1049.0
If we subtract 7029 from 7702, we get 673.
Fetch the next digit (4) from the dividend, attach it to 673 and continue: 6734 / 781

Step 7:
781 goes into 6734 8 times with a remainder of 486.
Record the quotient 8 as the next digit in the result. 
Result so far: 10498.0
If we take 6248 away from 6734, we end up with 486.
Include the next digit (0) from the dividend after 486, then repeat: 4860 / 781

Going ahead to step 8:
If we divide 4860 by 781, we get 6 and a remainder of 174.
The number 6 becomes the next digit in our result. 
Result so far: 104986.0
Subtracting 4686 from 4860 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:
If we divide 1740 by 781, we get 2 and a remainder of 178.
Use 2 as the next digit of our solution. 
Result so far: 104986.2
Subtracting 1562 from 1740 leaves us 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.

Moving on to step 10:
781 goes into 1780 2 times with a remainder of 218.
Record the quotient 2 as the next digit in the result. 
Result so far: 104986.22
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.

After the division, we end up with 104986.22 and a remainder of 0.218.
