We look at the division of 539430 by 89 
We want to figure out the number of times 539430 can be divided by 89.

Step 1:
The number 89 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 89

Going ahead to step 2:
The number 89 fits into 53 0 times, leaving a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Take the next digit (9) from the dividend and append it to 53, then repeat: 539 / 89

Advancing to step 3:
When dividing 539 by 89, we get 6 with a remainder of 5.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 534 away from 539, we end up with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 89

Moving on to step 4:
When dividing 54 by 89, we get 0 with a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 60.0
If we take 0 away from 54, we end up with 54.
Bring next digit (3) of the dividend behind the 54 and repeat the process: 543 / 89

Step 5:
The number 89 fits into 543 6 times, leaving a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 606.0
Subtracting 534 from 543 leaves us with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 89

Advancing to step 6:
The number 89 fits into 90 1 times, leaving a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 6061.0
Subtracting 89 from 90 leaves us 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.

Step 7:
89 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 6061.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
The number 89 fits into 100 1 times, leaving a remainder of 11.
The next digit of our result is 1. 
Result so far: 6061.01
If we subtract 89 from 100, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 9:
The number 89 fits into 110 1 times, leaving a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 6061.011
The remainder is 21 after subtracting 89 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

After the division, we end up with 6061.011 and a remainder of 0.0021.
