Let's divide 573040 by 81
We want to figure out the number of times 573040 can be divided by 81.

Let's proceed to step 1:
81 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 81

Step 2:
If we divide 57 by 81, we get 0 and a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Take the next digit (3) from the dividend and append it to 57, then repeat: 573 / 81

On to step 3:
The number 81 fits into 573 7 times, leaving a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 567 from 573 and we're left with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 81

Let's proceed to step 4:
When dividing 60 by 81, we get 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 70.0
Subtract 0 from 60 to get 60.
Include the next digit (4) from the dividend after 60, then repeat: 604 / 81

Advancing to step 5:
If we divide 604 by 81, we get 7 and a remainder of 37.
The next digit of our result is 7. 
Result so far: 707.0
Deduct 567 from 604 and we're left with 37.
Take the next digit (0) from the dividend and append it to 37, then repeat: 370 / 81

On to step 6:
If we divide 370 by 81, we get 4 and a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 7074.0
Subtract 324 from 370 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 7:
81 goes into 460 5 times with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 7074.5
If we subtract 405 from 460, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 8:
81 can be fit into 550 6 times, resulting in a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 7074.56
If we take 486 away from 550, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 9:
The number 81 fits into 640 7 times, leaving a remainder of 73.
Use 7 as the next digit of our solution. 
Result so far: 7074.567
If we subtract 567 from 640, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 10:
When dividing 730 by 81, we get 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 7074.5679
If we take 729 away from 730, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 11:
When dividing 10 by 81, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 7074.5679
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
100 divided by 81 is 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 7074.567901
Deduct 81 from 100 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 13:
190 divided by 81 is 2 with a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 7074.5679012
If we subtract 162 from 190, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 14:
81 can be fit into 280 3 times, resulting in a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 7074.56790123
The remainder is 37 after subtracting 243 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

After the division, we end up with 7074.56790123 and a remainder of 3.7e-08.
