Let's divide 578743 by 81
We're looking to find how many times 81 goes into 578743.

Advancing to step 1:
When dividing 5 by 81, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 81

Going ahead to step 2:
If we divide 57 by 81, we get 0 and a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Take the next digit (8) from the dividend and append it to 57, then repeat: 578 / 81

Moving on to step 3:
81 can be fit into 578 7 times, resulting in a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 567 away from 578, we end up with 11.
Bring next digit (7) of the dividend behind the 11 and repeat the process: 117 / 81

On to step 4:
If we divide 117 by 81, we get 1 and a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 71.0
If we take 81 away from 117, we end up with 36.
Bring next digit (4) of the dividend behind the 36 and repeat the process: 364 / 81

Going ahead to step 5:
364 divided by 81 is 4 with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 714.0
Subtracting 324 from 364 leaves us with 40.
Fetch the next digit (3) from the dividend, attach it to 40 and continue: 403 / 81

Going ahead to step 6:
403 divided by 81 is 4 with a remainder of 79.
Write down 4 as next digit of the result. 
Result so far: 7144.0
Subtract 324 from 403 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 7:
790 divided by 81 is 9 with a remainder of 61.
Put 9 as the next digit of the answer. 
Result so far: 7144.9
If we take 729 away from 790, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 8:
When dividing 610 by 81, we get 7 with a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 7144.97
Subtracting 567 from 610 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 9:
The number 81 fits into 430 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 7144.975
Subtract 405 from 430 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.

Moving on to step 10:
The number 81 fits into 250 3 times, leaving a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 7144.9753
If we take 243 away from 250, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 11:
If we divide 70 by 81, we get 0 and a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 7144.9753
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 12:
When dividing 700 by 81, we get 8 with a remainder of 52.
The next digit of our result is 8. 
Result so far: 7144.975308
Subtract 648 from 700 to 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 13:
If we divide 520 by 81, we get 6 and a remainder of 34.
The next digit of our result is 6. 
Result so far: 7144.9753086
Subtract 486 from 520 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 14:
340 divided by 81 is 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 7144.97530864
If we subtract 324 from 340, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 7144.97530864, with a leftover of 1.6e-08.
