87343 ÷ 81 
We want to figure out the number of times 87343 can be divided by 81.

Going ahead to step 1:
81 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 81

Moving on to step 2:
87 divided by 81 is 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 81 away from 87, we end up with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 81

Advancing to step 3:
81 can be fit into 63 0 times, resulting in a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 63 to get 63.
Grab the next digit (4) from the dividend, add it to 63, then carry on: 634 / 81

Going ahead to step 4:
634 divided by 81 is 7 with a remainder of 67.
Use 7 as the next digit of our solution. 
Result so far: 107.0
If we take 567 away from 634, we end up with 67.
Grab the next digit (3) from the dividend, add it to 67, then carry on: 673 / 81

Advancing to step 5:
If we divide 673 by 81, we get 8 and a remainder of 25.
Put 8 as the next digit of the answer. 
Result so far: 1078.0
Subtract 648 from 673 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 6:
250 divided by 81 is 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 1078.3
Subtract 243 from 250 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
70 divided by 81 is 0 with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 1078.3
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 8:
81 goes into 700 8 times with a remainder of 52.
The next digit of our result is 8. 
Result so far: 1078.308
If we subtract 648 from 700, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 9:
520 divided by 81 is 6 with a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 1078.3086
Subtracting 486 from 520 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 10:
340 divided by 81 is 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 1078.30864
The remainder is 16 after subtracting 324 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
The number 81 fits into 160 1 times, leaving a remainder of 79.
Write down 1 as next digit of the result. 
Result so far: 1078.308641
Subtracting 81 from 160 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 12:
The number 81 fits into 790 9 times, leaving a remainder of 61.
The next digit of our result is 9. 
Result so far: 1078.3086419
If we subtract 729 from 790, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 13:
81 can be fit into 610 7 times, resulting in a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 1078.30864197
If we subtract 567 from 610, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Our division results in 1078.30864197 with a remaining 4.3e-08.
