427665 ÷ 81 
Our goal is to divide 427665 by 81.

Let's proceed to step 1:
4 divided by 81 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 81

Advancing to step 2:
If we divide 42 by 81, we get 0 and a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Fetch the next digit (7) from the dividend, attach it to 42 and continue: 427 / 81

Going ahead to step 3:
When dividing 427 by 81, we get 5 with a remainder of 22.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 405 from 427 and we're left with 22.
Take the next digit (6) from the dividend and append it to 22, then repeat: 226 / 81

Let's proceed to step 4:
When dividing 226 by 81, we get 2 with a remainder of 64.
The next digit of our result is 2. 
Result so far: 52.0
Deduct 162 from 226 and we're left with 64.
Bring next digit (6) of the dividend behind the 64 and repeat the process: 646 / 81

Advancing to step 5:
If we divide 646 by 81, we get 7 and a remainder of 79.
The next digit of our result is 7. 
Result so far: 527.0
Subtracting 567 from 646 leaves us with 79.
Take the next digit (5) from the dividend and append it to 79, then repeat: 795 / 81

Moving on to step 6:
81 goes into 795 9 times with a remainder of 66.
The next digit of our result is 9. 
Result so far: 5279.0
If we take 729 away from 795, we end up with 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 7:
When dividing 660 by 81, we get 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 5279.8
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.

Advancing to step 8:
81 can be fit into 120 1 times, resulting in a remainder of 39.
The next digit of our result is 1. 
Result so far: 5279.81
If we take 81 away from 120, we end up 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.

Going ahead to step 9:
The number 81 fits into 390 4 times, leaving a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 5279.814
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.

Advancing to step 10:
660 divided by 81 is 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 5279.8148
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.

Going ahead to step 11:
81 goes into 120 1 times with a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 5279.81481
If we subtract 81 from 120, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 12:
When dividing 390 by 81, we get 4 with a remainder of 66.
Write down 4 as next digit of the result. 
Result so far: 5279.814814
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.

Let's proceed to step 13:
The number 81 fits into 660 8 times, leaving a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 5279.8148148
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.

Advancing to step 14:
120 divided by 81 is 1 with a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 5279.81481481
Subtract 81 from 120 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The quotient of the division is 5279.81481481, and the remainder is 3.9e-08.
