787443 ÷ 81 
We want to figure out the number of times 787443 can be divided by 81.

On to step 1:
81 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 81

Let's proceed to step 2:
81 can be fit into 78 0 times, resulting in a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Include the next digit (7) from the dividend after 78, then repeat: 787 / 81

Let's proceed to step 3:
787 divided by 81 is 9 with a remainder of 58.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 729 from 787, we get 58.
Bring next digit (4) of the dividend behind the 58 and repeat the process: 584 / 81

On to step 4:
81 goes into 584 7 times with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
If we subtract 567 from 584, we get 17.
Append the next digit (4) from the dividend to 17 and continue with: 174 / 81

On to step 5:
81 can be fit into 174 2 times, resulting in a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 972.0
Deduct 162 from 174 and we're left with 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 81

Step 6:
81 can be fit into 123 1 times, resulting in a remainder of 42.
The next digit of our result is 1. 
Result so far: 9721.0
Subtracting 81 from 123 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 7:
The number 81 fits into 420 5 times, leaving a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 9721.5
The remainder is 15 after subtracting 405 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
If we divide 150 by 81, we get 1 and a remainder of 69.
Put 1 as the next digit of the answer. 
Result so far: 9721.51
Subtracting 81 from 150 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 9:
81 can be fit into 690 8 times, resulting in a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 9721.518
If we subtract 648 from 690, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 10:
When dividing 420 by 81, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 9721.5185
Subtract 405 from 420 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 11:
The number 81 fits into 150 1 times, leaving a remainder of 69.
The number 1 becomes the next digit in our result. 
Result so far: 9721.51851
Subtract 81 from 150 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 12:
If we divide 690 by 81, we get 8 and a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 9721.518518
Subtracting 648 from 690 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 13:
420 divided by 81 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 9721.5185185
Deduct 405 from 420 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 14:
The number 81 fits into 150 1 times, leaving a remainder of 69.
The next digit of our result is 1. 
Result so far: 9721.51851851
Subtracting 81 from 150 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

The final outcome is 9721.51851851, with a leftover of 6.9e-08.
