406712 ÷ 81 
Our goal is to divide 406712 by 81.

Step 1:
If we divide 4 by 81, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 81

Step 2:
40 divided by 81 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Grab the next digit (6) from the dividend, add it to 40, then carry on: 406 / 81

Advancing to step 3:
81 can be fit into 406 5 times, resulting in a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 405 from 406 leaves us with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 81

Going ahead to step 4:
If we divide 17 by 81, we get 0 and a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
Deduct 0 from 17 and we're left with 17.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 81

Step 5:
81 goes into 171 2 times with a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 502.0
Subtract 162 from 171 to get 9.
Append the next digit (2) from the dividend to 9 and continue with: 92 / 81

Advancing to step 6:
When dividing 92 by 81, we get 1 with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 5021.0
Subtracting 81 from 92 leaves us 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 7:
The number 81 fits into 110 1 times, leaving a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 5021.1
If we take 81 away from 110, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 8:
81 can be fit into 290 3 times, resulting in a remainder of 47.
The next digit of our result is 3. 
Result so far: 5021.13
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.

Advancing to step 9:
The number 81 fits into 470 5 times, leaving a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 5021.135
Subtract 405 from 470 to 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.

Going ahead to step 10:
If we divide 650 by 81, we get 8 and a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 5021.1358
Deduct 648 from 650 and we're left 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 11:
If we divide 20 by 81, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 5021.1358
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
The number 81 fits into 200 2 times, leaving a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 5021.135802
The remainder is 38 after subtracting 162 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 13:
The number 81 fits into 380 4 times, leaving a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 5021.1358024
Subtract 324 from 380 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.

Going ahead to step 14:
The number 81 fits into 560 6 times, leaving a remainder of 74.
Write down 6 as next digit of the result. 
Result so far: 5021.13580246
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.

The final outcome is 5021.13580246, with a leftover of 7.4e-08.
