We're dividing 51518400 by 180 
We want to figure out the number of times 51518400 can be divided by 180.

Let's proceed to step 1:
180 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 180

Advancing to step 2:
If we divide 51 by 180, we get 0 and a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Fetch the next digit (5) from the dividend, attach it to 51 and continue: 515 / 180

On to step 3:
The number 180 fits into 515 2 times, leaving a remainder of 155.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 360 away from 515, we end up with 155.
Include the next digit (1) from the dividend after 155, then repeat: 1551 / 180

Advancing to step 4:
When dividing 1551 by 180, we get 8 with a remainder of 111.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
The remainder is 111 after subtracting 1440 from 1551.
Take the next digit (8) from the dividend and append it to 111, then repeat: 1118 / 180

Going ahead to step 5:
180 can be fit into 1118 6 times, resulting in a remainder of 38.
Write down 6 as next digit of the result. 
Result so far: 286.0
Subtracting 1080 from 1118 leaves us with 38.
Append the next digit (4) from the dividend to 38 and continue with: 384 / 180

Advancing to step 6:
If we divide 384 by 180, we get 2 and a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 2862.0
Deduct 360 from 384 and we're left with 24.
Include the next digit (0) from the dividend after 24, then repeat: 240 / 180

Step 7:
The number 180 fits into 240 1 times, leaving a remainder of 60.
Write down 1 as next digit of the result. 
Result so far: 28621.0
Subtracting 180 from 240 leaves us with 60.
Bring next digit (0) of the dividend behind the 60 and repeat the process: 600 / 180

Going ahead to step 8:
180 can be fit into 600 3 times, resulting in a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 286213.0
If we subtract 540 from 600, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 9:
180 can be fit into 600 3 times, resulting in a remainder of 60.
The next digit of our result is 3. 
Result so far: 286213.3
Deduct 540 from 600 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 10:
If we divide 600 by 180, we get 3 and a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 286213.33
The remainder is 60 after subtracting 540 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

In conclusion, the division gives 286213.33 with a balance of 0.06.
