Let's divide 54539243 by 180
Our goal is to divide 54539243 by 180.

On to step 1:
If we divide 5 by 180, we get 0 and 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.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 180

Step 2:
180 goes into 54 0 times with a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 54 after subtracting 0 from 54.
Append the next digit (5) from the dividend to 54 and continue with: 545 / 180

Advancing to step 3:
180 goes into 545 3 times with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 540 away from 545, we end up with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 180

Let's proceed to step 4:
The number 180 fits into 53 0 times, leaving a remainder of 53.
The next digit of our result is 0. 
Result so far: 30.0
Deduct 0 from 53 and we're left with 53.
Fetch the next digit (9) from the dividend, attach it to 53 and continue: 539 / 180

Advancing to step 5:
180 can be fit into 539 2 times, resulting in a remainder of 179.
Use 2 as the next digit of our solution. 
Result so far: 302.0
Subtracting 360 from 539 leaves us with 179.
Bring next digit (2) of the dividend behind the 179 and repeat the process: 1792 / 180

Moving on to step 6:
The number 180 fits into 1792 9 times, leaving a remainder of 172.
The next digit of our result is 9. 
Result so far: 3029.0
If we subtract 1620 from 1792, we get 172.
Fetch the next digit (4) from the dividend, attach it to 172 and continue: 1724 / 180

Moving on to step 7:
1724 divided by 180 is 9 with a remainder of 104.
The number 9 becomes the next digit in our result. 
Result so far: 30299.0
Deduct 1620 from 1724 and we're left with 104.
Bring next digit (3) of the dividend behind the 104 and repeat the process: 1043 / 180

Moving on to step 8:
When dividing 1043 by 180, we get 5 with a remainder of 143.
Write down 5 as next digit of the result. 
Result so far: 302995.0
Deduct 900 from 1043 and we're left with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

On to step 9:
When dividing 1430 by 180, we get 7 with a remainder of 170.
The next digit of our result is 7. 
Result so far: 302995.7
Subtract 1260 from 1430 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 10:
If we divide 1700 by 180, we get 9 and a remainder of 80.
Use 9 as the next digit of our solution. 
Result so far: 302995.79
Deduct 1620 from 1700 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 11:
The number 180 fits into 800 4 times, leaving a remainder of 80.
Put 4 as the next digit of the answer. 
Result so far: 302995.794
Subtract 720 from 800 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 12:
800 divided by 180 is 4 with a remainder of 80.
Record the quotient 4 as the next digit in the result. 
Result so far: 302995.7944
If we take 720 away from 800, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The quotient of the division is 302995.7944, and the remainder is 0.0008.
