We look at the division of 590537 by 45 
Our goal is to divide 590537 by 45.

On to step 1:
The number 45 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 45

Going ahead to step 2:
45 goes into 59 1 times with a remainder of 14.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 45 from 59 and we're left with 14.
Bring next digit (0) of the dividend behind the 14 and repeat the process: 140 / 45

Step 3:
When dividing 140 by 45, we get 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we subtract 135 from 140, we get 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 45

Going ahead to step 4:
If we divide 55 by 45, we get 1 and a remainder of 10.
The next digit of our result is 1. 
Result so far: 131.0
If we take 45 away from 55, we end up with 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 45

Let's proceed to step 5:
If we divide 103 by 45, we get 2 and a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 1312.0
If we take 90 away from 103, we end up with 13.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 45

Step 6:
45 goes into 137 3 times with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 13123.0
The remainder is 2 after subtracting 135 from 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
If we divide 20 by 45, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 13123.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
The number 45 fits into 200 4 times, leaving a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 13123.04
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
45 can be fit into 200 4 times, resulting in a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 13123.044
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 13123.044, with a leftover of 0.002.
