We're dividing 81873141 by 180 
Let's see how many times 180 fits into 81873141.

Let's proceed to step 1:
If we divide 8 by 180, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 180

Step 2:
If we divide 81 by 180, we get 0 and a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Take the next digit (8) from the dividend and append it to 81, then repeat: 818 / 180

Let's proceed to step 3:
180 goes into 818 4 times with a remainder of 98.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 720 away from 818, we end up with 98.
Grab the next digit (7) from the dividend, add it to 98, then carry on: 987 / 180

Moving on to step 4:
If we divide 987 by 180, we get 5 and a remainder of 87.
Write down 5 as next digit of the result. 
Result so far: 45.0
Subtracting 900 from 987 leaves us with 87.
Include the next digit (3) from the dividend after 87, then repeat: 873 / 180

Going ahead to step 5:
When dividing 873 by 180, we get 4 with a remainder of 153.
Write down 4 as next digit of the result. 
Result so far: 454.0
Subtract 720 from 873 to get 153.
Include the next digit (1) from the dividend after 153, then repeat: 1531 / 180

Step 6:
180 can be fit into 1531 8 times, resulting in a remainder of 91.
Record the quotient 8 as the next digit in the result. 
Result so far: 4548.0
Subtracting 1440 from 1531 leaves us with 91.
Append the next digit (4) from the dividend to 91 and continue with: 914 / 180

Going ahead to step 7:
180 goes into 914 5 times with a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 45485.0
If we take 900 away from 914, we end up with 14.
Bring next digit (1) of the dividend behind the 14 and repeat the process: 141 / 180

Let's proceed to step 8:
141 divided by 180 is 0 with a remainder of 141.
Write down 0 as next digit of the result. 
Result so far: 454850.0
If we take 0 away from 141, we end up with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Step 9:
When dividing 1410 by 180, we get 7 with a remainder of 150.
Record the quotient 7 as the next digit in the result. 
Result so far: 454850.7
Deduct 1260 from 1410 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 10:
When dividing 1500 by 180, we get 8 with a remainder of 60.
The next digit of our result is 8. 
Result so far: 454850.78
If we subtract 1440 from 1500, 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.

Step 11:
180 can be fit into 600 3 times, resulting in a remainder of 60.
Write down 3 as next digit of the result. 
Result so far: 454850.783
If we take 540 away from 600, we end up 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.

Step 12:
600 divided by 180 is 3 with a remainder of 60.
Use 3 as the next digit of our solution. 
Result so far: 454850.7833
Subtract 540 from 600 to 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.

The final result is 454850.7833 with a remainder of 0.0006.
