573842 ÷ 81 
We want to figure out the number of times 573842 can be divided by 81.

Step 1:
81 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 81

Let's proceed to step 2:
81 can be fit into 57 0 times, resulting in a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 57 to get 57.
Grab the next digit (3) from the dividend, add it to 57, then carry on: 573 / 81

Step 3:
If we divide 573 by 81, we get 7 and a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 567 from 573 and we're left with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 81

Advancing to step 4:
68 divided by 81 is 0 with a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 70.0
If we subtract 0 from 68, we get 68.
Fetch the next digit (4) from the dividend, attach it to 68 and continue: 684 / 81

Moving on to step 5:
81 can be fit into 684 8 times, resulting in a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 708.0
Subtracting 648 from 684 leaves us with 36.
Bring next digit (2) of the dividend behind the 36 and repeat the process: 362 / 81

Advancing to step 6:
81 goes into 362 4 times with a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 7084.0
Subtract 324 from 362 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 7:
The number 81 fits into 380 4 times, leaving a remainder of 56.
The next digit of our result is 4. 
Result so far: 7084.4
If we subtract 324 from 380, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 8:
The number 81 fits into 560 6 times, leaving a remainder of 74.
The next digit of our result is 6. 
Result so far: 7084.46
Subtract 486 from 560 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 9:
If we divide 740 by 81, we get 9 and a remainder of 11.
The next digit of our result is 9. 
Result so far: 7084.469
Subtracting 729 from 740 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 10:
If we divide 110 by 81, we get 1 and a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 7084.4691
Subtract 81 from 110 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 11:
81 can be fit into 290 3 times, resulting in a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 7084.46913
If we subtract 243 from 290, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 12:
The number 81 fits into 470 5 times, leaving a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 7084.469135
If we subtract 405 from 470, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 13:
When dividing 650 by 81, we get 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 7084.4691358
If we subtract 648 from 650, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 14:
20 divided by 81 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 7084.4691358
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 7084.4691358, with a leftover of 2e-08.
