53937 divided by 90 
We're looking to find how many times 90 goes into 53937.

Step 1:
5 divided by 90 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 90

Step 2:
53 divided by 90 is 0 with a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Take the next digit (9) from the dividend and append it to 53, then repeat: 539 / 90

Moving on to step 3:
90 goes into 539 5 times with a remainder of 89.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 450 away from 539, we end up with 89.
Include the next digit (3) from the dividend after 89, then repeat: 893 / 90

Step 4:
90 goes into 893 9 times with a remainder of 83.
Use 9 as the next digit of our solution. 
Result so far: 59.0
The remainder is 83 after subtracting 810 from 893.
Bring next digit (7) of the dividend behind the 83 and repeat the process: 837 / 90

Going ahead to step 5:
If we divide 837 by 90, we get 9 and a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 599.0
If we take 810 away from 837, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 6:
90 goes into 270 3 times with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 599.3
If we subtract 270 from 270, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
The number 90 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 599.3
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
If we divide 0 by 90, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 599.3
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 599.3 with a remainder of 0.0.
