81343440 ÷ 180 
We want to divide 81343440 by 180.

Going ahead to step 1:
180 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 180

On to step 2:
180 goes into 81 0 times with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Include the next digit (3) from the dividend after 81, then repeat: 813 / 180

Step 3:
If we divide 813 by 180, we get 4 and a remainder of 93.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 720 away from 813, we end up with 93.
Fetch the next digit (4) from the dividend, attach it to 93 and continue: 934 / 180

Advancing to step 4:
180 goes into 934 5 times with a remainder of 34.
Put 5 as the next digit of the answer. 
Result so far: 45.0
If we take 900 away from 934, we end up with 34.
Take the next digit (3) from the dividend and append it to 34, then repeat: 343 / 180

Moving on to step 5:
The number 180 fits into 343 1 times, leaving a remainder of 163.
Use 1 as the next digit of our solution. 
Result so far: 451.0
If we take 180 away from 343, we end up with 163.
Grab the next digit (4) from the dividend, add it to 163, then carry on: 1634 / 180

On to step 6:
180 goes into 1634 9 times with a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 4519.0
Subtracting 1620 from 1634 leaves us with 14.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 180

Going ahead to step 7:
180 goes into 144 0 times with a remainder of 144.
Record the quotient 0 as the next digit in the result. 
Result so far: 45190.0
Subtracting 0 from 144 leaves us with 144.
Grab the next digit (0) from the dividend, add it to 144, then carry on: 1440 / 180

Step 8:
180 can be fit into 1440 8 times, resulting in a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 451908.0
Subtracting 1440 from 1440 leaves us 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.

Step 9:
If we divide 0 by 180, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 451908.0
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.

Going ahead to step 10:
If we divide 0 by 180, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 451908.0
Deduct 0 from 0 and we're left 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 451908.0, and the remainder is 0.0.
