Let's divide 140289 by 90
Let's see how many times 90 fits into 140289.

Step 1:
90 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 90

On to step 2:
90 can be fit into 14 0 times, resulting in a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Bring next digit (0) of the dividend behind the 14 and repeat the process: 140 / 90

Going ahead to step 3:
90 can be fit into 140 1 times, resulting in a remainder of 50.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 90 from 140 to get 50.
Fetch the next digit (2) from the dividend, attach it to 50 and continue: 502 / 90

Advancing to step 4:
If we divide 502 by 90, we get 5 and a remainder of 52.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 450 from 502 to get 52.
Grab the next digit (8) from the dividend, add it to 52, then carry on: 528 / 90

Step 5:
90 goes into 528 5 times with a remainder of 78.
The next digit of our result is 5. 
Result so far: 155.0
If we take 450 away from 528, we end up with 78.
Bring next digit (9) of the dividend behind the 78 and repeat the process: 789 / 90

On to step 6:
If we divide 789 by 90, we get 8 and a remainder of 69.
The number 8 becomes the next digit in our result. 
Result so far: 1558.0
If we subtract 720 from 789, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 7:
The number 90 fits into 690 7 times, leaving a remainder of 60.
Write down 7 as next digit of the result. 
Result so far: 1558.7
If we subtract 630 from 690, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 8:
If we divide 600 by 90, we get 6 and a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 1558.76
If we subtract 540 from 600, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
If we divide 600 by 90, we get 6 and a remainder of 60.
The next digit of our result is 6. 
Result so far: 1558.766
If we subtract 540 from 600, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The quotient of the division is 1558.766, and the remainder is 0.006.
