We look at the division of 525518 by 90 
We want to divide 525518 by 90.

Let's proceed to step 1:
If we divide 5 by 90, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 90

On to step 2:
If we divide 52 by 90, we get 0 and a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Fetch the next digit (5) from the dividend, attach it to 52 and continue: 525 / 90

Let's proceed to step 3:
If we divide 525 by 90, we get 5 and a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 450 from 525, we get 75.
Grab the next digit (5) from the dividend, add it to 75, then carry on: 755 / 90

Going ahead to step 4:
90 can be fit into 755 8 times, resulting in a remainder of 35.
The number 8 becomes the next digit in our result. 
Result so far: 58.0
Deduct 720 from 755 and we're left with 35.
Grab the next digit (1) from the dividend, add it to 35, then carry on: 351 / 90

On to step 5:
If we divide 351 by 90, we get 3 and a remainder of 81.
Write down 3 as next digit of the result. 
Result so far: 583.0
Subtract 270 from 351 to get 81.
Bring next digit (8) of the dividend behind the 81 and repeat the process: 818 / 90

Advancing to step 6:
The number 90 fits into 818 9 times, leaving a remainder of 8.
The next digit of our result is 9. 
Result so far: 5839.0
If we subtract 810 from 818, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
The number 90 fits into 80 0 times, leaving a remainder of 80.
The next digit of our result is 0. 
Result so far: 5839.0
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 8:
90 can be fit into 800 8 times, resulting in a remainder of 80.
Put 8 as the next digit of the answer. 
Result so far: 5839.08
Deduct 720 from 800 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 9:
90 can be fit into 800 8 times, resulting in a remainder of 80.
Put 8 as the next digit of the answer. 
Result so far: 5839.088
Subtracting 720 from 800 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The quotient of the division is 5839.088, and the remainder is 0.008.
