We divide 591938 by 90
We're looking to find how many times 90 goes into 591938.

Advancing to step 1:
If we divide 5 by 90, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 90

Going ahead to step 2:
If we divide 59 by 90, we get 0 and a remainder of 59.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 59 and we're left with 59.
Append the next digit (1) from the dividend to 59 and continue with: 591 / 90

Advancing to step 3:
The number 90 fits into 591 6 times, leaving a remainder of 51.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 540 from 591 leaves us with 51.
Append the next digit (9) from the dividend to 51 and continue with: 519 / 90

Going ahead to step 4:
90 goes into 519 5 times with a remainder of 69.
Use 5 as the next digit of our solution. 
Result so far: 65.0
If we take 450 away from 519, we end up with 69.
Fetch the next digit (3) from the dividend, attach it to 69 and continue: 693 / 90

Advancing to step 5:
90 can be fit into 693 7 times, resulting in a remainder of 63.
The number 7 becomes the next digit in our result. 
Result so far: 657.0
Subtract 630 from 693 to get 63.
Bring next digit (8) of the dividend behind the 63 and repeat the process: 638 / 90

Step 6:
The number 90 fits into 638 7 times, leaving a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 6577.0
If we subtract 630 from 638, 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.

Advancing to step 7:
90 goes into 80 0 times with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 6577.0
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 8:
90 goes into 800 8 times with a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 6577.08
If we subtract 720 from 800, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 9:
When dividing 800 by 90, we get 8 with a remainder of 80.
The next digit of our result is 8. 
Result so far: 6577.088
The remainder is 80 after subtracting 720 from 800.
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 6577.088, and the remainder is 0.008.
