Let's divide 56593 by 90
We want to figure out the number of times 56593 can be divided by 90.

Step 1:
If we divide 5 by 90, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 90

On to step 2:
The number 90 fits into 56 0 times, leaving a remainder of 56.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 56 and we're left with 56.
Take the next digit (5) from the dividend and append it to 56, then repeat: 565 / 90

Let's proceed to step 3:
90 can be fit into 565 6 times, resulting in a remainder of 25.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 540 from 565 to get 25.
Fetch the next digit (9) from the dividend, attach it to 25 and continue: 259 / 90

On to step 4:
90 goes into 259 2 times with a remainder of 79.
Use 2 as the next digit of our solution. 
Result so far: 62.0
If we take 180 away from 259, we end up with 79.
Grab the next digit (3) from the dividend, add it to 79, then carry on: 793 / 90

On to step 5:
793 divided by 90 is 8 with a remainder of 73.
Record the quotient 8 as the next digit in the result. 
Result so far: 628.0
If we take 720 away from 793, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 6:
When dividing 730 by 90, we get 8 with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 628.8
If we subtract 720 from 730, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
100 divided by 90 is 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 628.81
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
When dividing 100 by 90, we get 1 with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 628.811
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 628.811 with a remaining 0.001.
