We divide 443612 by 81
We want to divide 443612 by 81.

Advancing to step 1:
When dividing 4 by 81, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 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
Deduct 0 from 44 and we're left with 44.
Include the next digit (3) from the dividend after 44, then repeat: 443 / 81

On to step 3:
The number 81 fits into 443 5 times, leaving a remainder of 38.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 405 from 443 leaves us with 38.
Include the next digit (6) from the dividend after 38, then repeat: 386 / 81

Step 4:
If we divide 386 by 81, we get 4 and a remainder of 62.
Write down 4 as next digit of the result. 
Result so far: 54.0
Subtracting 324 from 386 leaves us with 62.
Grab the next digit (1) from the dividend, add it to 62, then carry on: 621 / 81

Step 5:
The number 81 fits into 621 7 times, leaving a remainder of 54.
Record the quotient 7 as the next digit in the result. 
Result so far: 547.0
Subtract 567 from 621 to get 54.
Append the next digit (2) from the dividend to 54 and continue with: 542 / 81

Step 6:
When dividing 542 by 81, we get 6 with a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 5476.0
Subtract 486 from 542 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 7:
81 can be fit into 560 6 times, resulting in a remainder of 74.
The number 6 becomes the next digit in our result. 
Result so far: 5476.6
If we take 486 away from 560, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 8:
81 goes into 740 9 times with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 5476.69
Deduct 729 from 740 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 9:
81 can be fit into 110 1 times, resulting in a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 5476.691
The remainder is 29 after subtracting 81 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 10:
When dividing 290 by 81, we get 3 with a remainder of 47.
The next digit of our result is 3. 
Result so far: 5476.6913
Deduct 243 from 290 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 11:
81 can be fit into 470 5 times, resulting in a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 5476.69135
If we subtract 405 from 470, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 12:
When dividing 650 by 81, we get 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 5476.691358
Subtracting 648 from 650 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 13:
81 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 5476.691358
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 14:
The number 81 fits into 200 2 times, leaving a remainder of 38.
The next digit of our result is 2. 
Result so far: 5476.69135802
Subtract 162 from 200 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final result is 5476.69135802 with a remainder of 3.8e-08.
