Let's divide 507289 by 90
We want to figure out the number of times 507289 can be divided by 90.

On to step 1:
90 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 90

Moving on to step 2:
When dividing 50 by 90, we get 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 50 leaves us with 50.
Append the next digit (7) from the dividend to 50 and continue with: 507 / 90

Let's proceed to step 3:
If we divide 507 by 90, we get 5 and a remainder of 57.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 450 from 507, we get 57.
Grab the next digit (2) from the dividend, add it to 57, then carry on: 572 / 90

Going ahead to step 4:
If we divide 572 by 90, we get 6 and a remainder of 32.
The next digit of our result is 6. 
Result so far: 56.0
The remainder is 32 after subtracting 540 from 572.
Bring next digit (8) of the dividend behind the 32 and repeat the process: 328 / 90

Step 5:
90 goes into 328 3 times with a remainder of 58.
Write down 3 as next digit of the result. 
Result so far: 563.0
If we take 270 away from 328, we end up with 58.
Append the next digit (9) from the dividend to 58 and continue with: 589 / 90

Advancing to step 6:
589 divided by 90 is 6 with a remainder of 49.
Use 6 as the next digit of our solution. 
Result so far: 5636.0
Deduct 540 from 589 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 7:
90 can be fit into 490 5 times, resulting in a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 5636.5
If we take 450 away from 490, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
400 divided by 90 is 4 with a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 5636.54
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
400 divided by 90 is 4 with a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 5636.544
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 5636.544 with a remainder of 0.004.
