495139 divided by 90 
We want to divide 495139 by 90.

Moving on to step 1:
90 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 90

Going ahead to step 2:
The number 90 fits into 49 0 times, leaving a remainder of 49.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 49 after subtracting 0 from 49.
Grab the next digit (5) from the dividend, add it to 49, then carry on: 495 / 90

Advancing to step 3:
495 divided by 90 is 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 450 from 495, we get 45.
Grab the next digit (1) from the dividend, add it to 45, then carry on: 451 / 90

Moving on to step 4:
90 can be fit into 451 5 times, resulting in a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 55.0
If we subtract 450 from 451, we get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 90

Moving on to step 5:
The number 90 fits into 13 0 times, leaving a remainder of 13.
The next digit of our result is 0. 
Result so far: 550.0
If we subtract 0 from 13, we get 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 90

Step 6:
139 divided by 90 is 1 with a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 5501.0
Deduct 90 from 139 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 7:
90 can be fit into 490 5 times, resulting in a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 5501.5
If we take 450 away from 490, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 8:
400 divided by 90 is 4 with a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 5501.54
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
If we divide 400 by 90, we get 4 and a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 5501.544
Subtracting 360 from 400 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 5501.544 with a remainder of 0.004.
