403471 ÷ 81 
Our goal is to divide 403471 by 81.

Advancing to step 1:
If we divide 4 by 81, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 81

Let's proceed to step 2:
If we divide 40 by 81, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Fetch the next digit (3) from the dividend, attach it to 40 and continue: 403 / 81

Let's proceed to step 3:
If we divide 403 by 81, we get 4 and a remainder of 79.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 324 from 403 and we're left with 79.
Bring next digit (4) of the dividend behind the 79 and repeat the process: 794 / 81

Going ahead to step 4:
81 can be fit into 794 9 times, resulting in a remainder of 65.
The next digit of our result is 9. 
Result so far: 49.0
If we take 729 away from 794, we end up with 65.
Include the next digit (7) from the dividend after 65, then repeat: 657 / 81

Advancing to step 5:
When dividing 657 by 81, we get 8 with a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 498.0
The remainder is 9 after subtracting 648 from 657.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 81

Step 6:
81 goes into 91 1 times with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 4981.0
If we subtract 81 from 91, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
81 goes into 100 1 times with a remainder of 19.
The next digit of our result is 1. 
Result so far: 4981.1
Subtracting 81 from 100 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 8:
When dividing 190 by 81, we get 2 with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 4981.12
Subtract 162 from 190 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
81 can be fit into 280 3 times, resulting in a remainder of 37.
The next digit of our result is 3. 
Result so far: 4981.123
If we take 243 away from 280, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 10:
When dividing 370 by 81, we get 4 with a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 4981.1234
If we subtract 324 from 370, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 11:
The number 81 fits into 460 5 times, leaving a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 4981.12345
If we take 405 away from 460, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 12:
81 can be fit into 550 6 times, resulting in a remainder of 64.
The next digit of our result is 6. 
Result so far: 4981.123456
Subtract 486 from 550 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 13:
81 goes into 640 7 times with a remainder of 73.
Put 7 as the next digit of the answer. 
Result so far: 4981.1234567
Subtracting 567 from 640 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 14:
When dividing 730 by 81, we get 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 4981.12345679
Deduct 729 from 730 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final outcome is 4981.12345679, with a leftover of 1e-09.
