363030 ÷ 81 
We want to divide 363030 by 81.

On to step 1:
The number 81 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 81

Going ahead to step 2:
81 goes into 36 0 times with a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 36 to get 36.
Include the next digit (3) from the dividend after 36, then repeat: 363 / 81

Step 3:
81 goes into 363 4 times with a remainder of 39.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 324 away from 363, we end up with 39.
Append the next digit (0) from the dividend to 39 and continue with: 390 / 81

On to step 4:
The number 81 fits into 390 4 times, leaving a remainder of 66.
Write down 4 as next digit of the result. 
Result so far: 44.0
Deduct 324 from 390 and we're left with 66.
Bring next digit (3) of the dividend behind the 66 and repeat the process: 663 / 81

Step 5:
When dividing 663 by 81, we get 8 with a remainder of 15.
The next digit of our result is 8. 
Result so far: 448.0
Deduct 648 from 663 and we're left with 15.
Fetch the next digit (0) from the dividend, attach it to 15 and continue: 150 / 81

Step 6:
When dividing 150 by 81, we get 1 with a remainder of 69.
The number 1 becomes the next digit in our result. 
Result so far: 4481.0
Deduct 81 from 150 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 7:
81 can be fit into 690 8 times, resulting in a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 4481.8
If we subtract 648 from 690, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 8:
81 goes into 420 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 4481.85
If we take 405 away from 420, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 9:
When dividing 150 by 81, we get 1 with a remainder of 69.
The number 1 becomes the next digit in our result. 
Result so far: 4481.851
Subtract 81 from 150 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 10:
690 divided by 81 is 8 with a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 4481.8518
If we subtract 648 from 690, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 11:
81 can be fit into 420 5 times, resulting in a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 4481.85185
If we take 405 away from 420, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 12:
The number 81 fits into 150 1 times, leaving a remainder of 69.
The number 1 becomes the next digit in our result. 
Result so far: 4481.851851
Subtract 81 from 150 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 13:
81 goes into 690 8 times with a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 4481.8518518
The remainder is 42 after subtracting 648 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 14:
If we divide 420 by 81, we get 5 and a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 4481.85185185
The remainder is 15 after subtracting 405 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 4481.85185185 with a remainder of 1.5e-08.
