81623977 divided by 781 
We want to divide 81623977 by 781.

Step 1:
When dividing 8 by 781, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 781

Step 2:
781 goes into 81 0 times with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Append the next digit (6) from the dividend to 81 and continue with: 816 / 781

Let's proceed to step 3:
781 can be fit into 816 1 times, resulting in a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 781 from 816 and we're left with 35.
Take the next digit (2) from the dividend and append it to 35, then repeat: 352 / 781

Let's proceed to step 4:
The number 781 fits into 352 0 times, leaving a remainder of 352.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 352 leaves us with 352.
Append the next digit (3) from the dividend to 352 and continue with: 3523 / 781

Going ahead to step 5:
3523 divided by 781 is 4 with a remainder of 399.
Write down 4 as next digit of the result. 
Result so far: 104.0
If we subtract 3124 from 3523, we get 399.
Append the next digit (9) from the dividend to 399 and continue with: 3999 / 781

Going ahead to step 6:
If we divide 3999 by 781, we get 5 and a remainder of 94.
Record the quotient 5 as the next digit in the result. 
Result so far: 1045.0
Subtracting 3905 from 3999 leaves us with 94.
Fetch the next digit (7) from the dividend, attach it to 94 and continue: 947 / 781

Step 7:
947 divided by 781 is 1 with a remainder of 166.
Put 1 as the next digit of the answer. 
Result so far: 10451.0
Subtracting 781 from 947 leaves us with 166.
Append the next digit (7) from the dividend to 166 and continue with: 1667 / 781

Going ahead to step 8:
When dividing 1667 by 781, we get 2 with a remainder of 105.
Write down 2 as next digit of the result. 
Result so far: 104512.0
If we subtract 1562 from 1667, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Let's proceed to step 9:
The number 781 fits into 1050 1 times, leaving a remainder of 269.
Put 1 as the next digit of the answer. 
Result so far: 104512.1
Deduct 781 from 1050 and we're left with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Moving on to step 10:
2690 divided by 781 is 3 with a remainder of 347.
Put 3 as the next digit of the answer. 
Result so far: 104512.13
Subtracting 2343 from 2690 leaves us with 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Moving on to step 11:
The number 781 fits into 3470 4 times, leaving a remainder of 346.
The number 4 becomes the next digit in our result. 
Result so far: 104512.134
Subtracting 3124 from 3470 leaves us with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Going ahead to step 12:
If we divide 3460 by 781, we get 4 and a remainder of 336.
The next digit of our result is 4. 
Result so far: 104512.1344
If we take 3124 away from 3460, we end up with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

The final result is 104512.1344 with a remainder of 0.00336.
