81407456 divided by 787 
We want to figure out the number of times 81407456 can be divided by 787.

On to step 1:
If we divide 8 by 787, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 787

Step 2:
The number 787 fits into 81 0 times, leaving a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Take the next digit (4) from the dividend and append it to 81, then repeat: 814 / 787

Going ahead to step 3:
787 can be fit into 814 1 times, resulting in a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 787 from 814 and we're left with 27.
Fetch the next digit (0) from the dividend, attach it to 27 and continue: 270 / 787

Let's proceed to step 4:
270 divided by 787 is 0 with a remainder of 270.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 270 to get 270.
Grab the next digit (7) from the dividend, add it to 270, then carry on: 2707 / 787

Advancing to step 5:
When dividing 2707 by 787, we get 3 with a remainder of 346.
Use 3 as the next digit of our solution. 
Result so far: 103.0
The remainder is 346 after subtracting 2361 from 2707.
Fetch the next digit (4) from the dividend, attach it to 346 and continue: 3464 / 787

Moving on to step 6:
787 can be fit into 3464 4 times, resulting in a remainder of 316.
Use 4 as the next digit of our solution. 
Result so far: 1034.0
The remainder is 316 after subtracting 3148 from 3464.
Append the next digit (5) from the dividend to 316 and continue with: 3165 / 787

Step 7:
The number 787 fits into 3165 4 times, leaving a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 10344.0
Subtract 3148 from 3165 to get 17.
Take the next digit (6) from the dividend and append it to 17, then repeat: 176 / 787

Moving on to step 8:
The number 787 fits into 176 0 times, leaving a remainder of 176.
Write down 0 as next digit of the result. 
Result so far: 103440.0
Deduct 0 from 176 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 9:
1760 divided by 787 is 2 with a remainder of 186.
Put 2 as the next digit of the answer. 
Result so far: 103440.2
Deduct 1574 from 1760 and we're left with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Advancing to step 10:
If we divide 1860 by 787, we get 2 and a remainder of 286.
The number 2 becomes the next digit in our result. 
Result so far: 103440.22
Deduct 1574 from 1860 and we're left with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

The final result is 103440.22 with a remainder of 0.286.
