We're dividing 181290 by 4 
Let's see how many times 4 fits into 181290.

On to step 1:
When dividing 1 by 4, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 4

Going ahead to step 2:
When dividing 18 by 4, we get 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 16 from 18, we get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 4

Advancing to step 3:
If we divide 21 by 4, we get 5 and a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 45.0
The remainder is 1 after subtracting 20 from 21.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 4

Let's proceed to step 4:
The number 4 fits into 12 3 times, leaving a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 453.0
Subtract 12 from 12 to get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 4

Step 5:
4 goes into 9 2 times with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 4532.0
Deduct 8 from 9 and we're left with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 4

Moving on to step 6:
10 divided by 4 is 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 45322.0
The remainder is 2 after subtracting 8 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
The number 4 fits into 20 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 45322.5
If we take 20 away from 20, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 45322.5
If we subtract 0 from 0, 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 9:
4 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 45322.5
If we take 0 away from 0, we end up with 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 45322.5, and the remainder is 0.0.
