We look at the division of 443919 by 81 
We want to divide 443919 by 81.

Moving on to step 1:
4 divided by 81 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 81

Going ahead to step 2:
81 goes into 44 0 times with a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 44 after subtracting 0 from 44.
Include the next digit (3) from the dividend after 44, then repeat: 443 / 81

Step 3:
The number 81 fits into 443 5 times, leaving a remainder of 38.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 405 from 443, we get 38.
Append the next digit (9) from the dividend to 38 and continue with: 389 / 81

Moving on to step 4:
389 divided by 81 is 4 with a remainder of 65.
Put 4 as the next digit of the answer. 
Result so far: 54.0
Deduct 324 from 389 and we're left with 65.
Append the next digit (1) from the dividend to 65 and continue with: 651 / 81

Going ahead to step 5:
The number 81 fits into 651 8 times, leaving a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 548.0
Subtracting 648 from 651 leaves us with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 81

Going ahead to step 6:
If we divide 39 by 81, we get 0 and a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 5480.0
Subtracting 0 from 39 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 7:
390 divided by 81 is 4 with a remainder of 66.
Put 4 as the next digit of the answer. 
Result so far: 5480.4
If we subtract 324 from 390, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 8:
When dividing 660 by 81, we get 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 5480.48
Deduct 648 from 660 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
When dividing 120 by 81, we get 1 with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 5480.481
The remainder is 39 after subtracting 81 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 10:
81 can be fit into 390 4 times, resulting in a remainder of 66.
Write down 4 as next digit of the result. 
Result so far: 5480.4814
Subtract 324 from 390 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 11:
81 goes into 660 8 times with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 5480.48148
Subtract 648 from 660 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 12:
120 divided by 81 is 1 with a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 5480.481481
The remainder is 39 after subtracting 81 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 13:
81 goes into 390 4 times with a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 5480.4814814
If we subtract 324 from 390, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 14:
81 can be fit into 660 8 times, resulting in a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 5480.48148148
The remainder is 12 after subtracting 648 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 5480.48148148 and a remainder of 1.2e-08.
