We divide 591044 by 90
We want to figure out the number of times 591044 can be divided by 90.

Advancing 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
Subtracting 0 from 5 leaves us with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 90

Let's proceed to step 2:
If we divide 59 by 90, we get 0 and a remainder of 59.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 59, we end up with 59.
Grab the next digit (1) from the dividend, add it to 59, then carry on: 591 / 90

Advancing to step 3:
90 goes into 591 6 times with a remainder of 51.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 540 from 591 leaves us with 51.
Include the next digit (0) from the dividend after 51, then repeat: 510 / 90

Let's proceed to step 4:
If we divide 510 by 90, we get 5 and a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 65.0
Subtracting 450 from 510 leaves us with 60.
Append the next digit (4) from the dividend to 60 and continue with: 604 / 90

Step 5:
90 can be fit into 604 6 times, resulting in a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 656.0
If we take 540 away from 604, we end up with 64.
Grab the next digit (4) from the dividend, add it to 64, then carry on: 644 / 90

On to step 6:
When dividing 644 by 90, we get 7 with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 6567.0
Deduct 630 from 644 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 7:
If we divide 140 by 90, we get 1 and a remainder of 50.
Record the quotient 1 as the next digit in the result. 
Result so far: 6567.1
Subtract 90 from 140 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
If we divide 500 by 90, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 6567.15
Deduct 450 from 500 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 9:
When dividing 500 by 90, we get 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 6567.155
The remainder is 50 after subtracting 450 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final result is 6567.155 with a remainder of 0.005.
