81885448 divided by 781 
Our goal is to divide 81885448 by 781.

Advancing to step 1:
When dividing 8 by 781, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 781

Moving on 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 take 0 away from 81, we end up with 81.
Append the next digit (8) from the dividend to 81 and continue with: 818 / 781

Step 3:
818 divided by 781 is 1 with a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 781 from 818 and we're left with 37.
Include the next digit (8) from the dividend after 37, then repeat: 378 / 781

Advancing to step 4:
The number 781 fits into 378 0 times, leaving a remainder of 378.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 378 and we're left with 378.
Take the next digit (5) from the dividend and append it to 378, then repeat: 3785 / 781

Step 5:
If we divide 3785 by 781, we get 4 and a remainder of 661.
Put 4 as the next digit of the answer. 
Result so far: 104.0
Deduct 3124 from 3785 and we're left with 661.
Append the next digit (4) from the dividend to 661 and continue with: 6614 / 781

On to step 6:
The number 781 fits into 6614 8 times, leaving a remainder of 366.
Record the quotient 8 as the next digit in the result. 
Result so far: 1048.0
If we subtract 6248 from 6614, we get 366.
Fetch the next digit (4) from the dividend, attach it to 366 and continue: 3664 / 781

Step 7:
The number 781 fits into 3664 4 times, leaving a remainder of 540.
Put 4 as the next digit of the answer. 
Result so far: 10484.0
The remainder is 540 after subtracting 3124 from 3664.
Fetch the next digit (8) from the dividend, attach it to 540 and continue: 5408 / 781

Moving on to step 8:
781 goes into 5408 6 times with a remainder of 722.
Record the quotient 6 as the next digit in the result. 
Result so far: 104846.0
The remainder is 722 after subtracting 4686 from 5408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7220, and continue the process.

Going ahead to step 9:
If we divide 7220 by 781, we get 9 and a remainder of 191.
Use 9 as the next digit of our solution. 
Result so far: 104846.9
Subtract 7029 from 7220 to get 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Step 10:
781 goes into 1910 2 times with a remainder of 348.
The number 2 becomes the next digit in our result. 
Result so far: 104846.92
If we take 1562 away from 1910, we end up with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Moving on to step 11:
If we divide 3480 by 781, we get 4 and a remainder of 356.
Write down 4 as next digit of the result. 
Result so far: 104846.924
Deduct 3124 from 3480 and we're left with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Let's proceed to step 12:
781 can be fit into 3560 4 times, resulting in a remainder of 436.
Use 4 as the next digit of our solution. 
Result so far: 104846.9244
If we subtract 3124 from 3560, we get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

The quotient of the division is 104846.9244, and the remainder is 0.00436.
