We're dividing 596241 by 90 
We want to figure out the number of times 596241 can be divided by 90.

On to step 1:
The number 90 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 90

Moving on to step 2:
The number 90 fits into 59 0 times, leaving a remainder of 59.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 59 and we're left with 59.
Append the next digit (6) from the dividend to 59 and continue with: 596 / 90

On to step 3:
When dividing 596 by 90, we get 6 with a remainder of 56.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 540 away from 596, we end up with 56.
Bring next digit (2) of the dividend behind the 56 and repeat the process: 562 / 90

On to step 4:
If we divide 562 by 90, we get 6 and a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 66.0
If we subtract 540 from 562, we get 22.
Grab the next digit (4) from the dividend, add it to 22, then carry on: 224 / 90

Moving on to step 5:
If we divide 224 by 90, we get 2 and a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 662.0
Deduct 180 from 224 and we're left with 44.
Include the next digit (1) from the dividend after 44, then repeat: 441 / 90

Moving on to step 6:
When dividing 441 by 90, we get 4 with a remainder of 81.
The number 4 becomes the next digit in our result. 
Result so far: 6624.0
The remainder is 81 after subtracting 360 from 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 7:
The number 90 fits into 810 9 times, leaving a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 6624.9
If we subtract 810 from 810, 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.

Moving on to step 8:
When dividing 0 by 90, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 6624.9
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
The number 90 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 6624.9
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 quotient of the division is 6624.9, and the remainder is 0.0.
