We look at the division of 543090 by 73 
Our goal is to divide 543090 by 73.

Let's proceed to step 1:
5 divided by 73 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 73

On to step 2:
73 can be fit into 54 0 times, resulting in a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Fetch the next digit (3) from the dividend, attach it to 54 and continue: 543 / 73

Step 3:
73 goes into 543 7 times with a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 511 from 543 leaves us with 32.
Bring next digit (0) of the dividend behind the 32 and repeat the process: 320 / 73

On to step 4:
73 goes into 320 4 times with a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 74.0
Subtracting 292 from 320 leaves us with 28.
Fetch the next digit (9) from the dividend, attach it to 28 and continue: 289 / 73

On to step 5:
73 goes into 289 3 times with a remainder of 70.
Use 3 as the next digit of our solution. 
Result so far: 743.0
Subtracting 219 from 289 leaves us with 70.
Fetch the next digit (0) from the dividend, attach it to 70 and continue: 700 / 73

Moving on to step 6:
When dividing 700 by 73, we get 9 with a remainder of 43.
Write down 9 as next digit of the result. 
Result so far: 7439.0
If we take 657 away from 700, we end up 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.

Let's proceed to step 7:
If we divide 430 by 73, we get 5 and a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 7439.5
If we subtract 365 from 430, 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.

Going ahead to step 8:
650 divided by 73 is 8 with a remainder of 66.
The number 8 becomes the next digit in our result. 
Result so far: 7439.58
The remainder is 66 after subtracting 584 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 9:
73 can be fit into 660 9 times, resulting in a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 7439.589
If we take 657 away from 660, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 10:
30 divided by 73 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 7439.589
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
If we divide 300 by 73, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 7439.58904
The remainder is 8 after subtracting 292 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
If we divide 80 by 73, we get 1 and a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 7439.589041
The remainder is 7 after subtracting 73 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 13:
The number 73 fits into 70 0 times, leaving a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 7439.589041
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 14:
73 can be fit into 700 9 times, resulting in a remainder of 43.
Put 9 as the next digit of the answer. 
Result so far: 7439.58904109
Subtract 657 from 700 to 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 7439.58904109 with a remaining 4.3e-08.
