We look at the division of 81408943 by 478 
Our goal is to divide 81408943 by 478.

Let's proceed to step 1:
When dividing 8 by 478, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 478

Let's proceed to step 2:
478 goes into 81 0 times with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Include the next digit (4) from the dividend after 81, then repeat: 814 / 478

On to step 3:
When dividing 814 by 478, we get 1 with a remainder of 336.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 336 after subtracting 478 from 814.
Bring next digit (0) of the dividend behind the 336 and repeat the process: 3360 / 478

Moving on to step 4:
3360 divided by 478 is 7 with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtract 3346 from 3360 to get 14.
Take the next digit (8) from the dividend and append it to 14, then repeat: 148 / 478

Let's proceed to step 5:
If we divide 148 by 478, we get 0 and a remainder of 148.
The next digit of our result is 0. 
Result so far: 170.0
If we subtract 0 from 148, we get 148.
Fetch the next digit (9) from the dividend, attach it to 148 and continue: 1489 / 478

Going ahead to step 6:
If we divide 1489 by 478, we get 3 and a remainder of 55.
Write down 3 as next digit of the result. 
Result so far: 1703.0
Deduct 1434 from 1489 and we're left with 55.
Bring next digit (4) of the dividend behind the 55 and repeat the process: 554 / 478

Advancing to step 7:
478 can be fit into 554 1 times, resulting in a remainder of 76.
Use 1 as the next digit of our solution. 
Result so far: 17031.0
The remainder is 76 after subtracting 478 from 554.
Bring next digit (3) of the dividend behind the 76 and repeat the process: 763 / 478

Advancing to step 8:
478 can be fit into 763 1 times, resulting in a remainder of 285.
The number 1 becomes the next digit in our result. 
Result so far: 170311.0
Subtracting 478 from 763 leaves us with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Advancing to step 9:
The number 478 fits into 2850 5 times, leaving a remainder of 460.
Record the quotient 5 as the next digit in the result. 
Result so far: 170311.5
If we subtract 2390 from 2850, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Moving on to step 10:
4600 divided by 478 is 9 with a remainder of 298.
The number 9 becomes the next digit in our result. 
Result so far: 170311.59
If we subtract 4302 from 4600, we get 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Let's proceed to step 11:
When dividing 2980 by 478, we get 6 with a remainder of 112.
The next digit of our result is 6. 
Result so far: 170311.596
If we subtract 2868 from 2980, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 12:
When dividing 1120 by 478, we get 2 with a remainder of 164.
Use 2 as the next digit of our solution. 
Result so far: 170311.5962
Subtracting 956 from 1120 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

On to step 13:
1640 divided by 478 is 3 with a remainder of 206.
Put 3 as the next digit of the answer. 
Result so far: 170311.59623
Subtracting 1434 from 1640 leaves us with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Let's proceed to step 14:
2060 divided by 478 is 4 with a remainder of 148.
Use 4 as the next digit of our solution. 
Result so far: 170311.596234
If we subtract 1912 from 2060, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Moving on to step 15:
When dividing 1480 by 478, we get 3 with a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 170311.5962343
If we take 1434 away from 1480, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 16:
478 goes into 460 0 times with a remainder of 460.
The number 0 becomes the next digit in our result. 
Result so far: 170311.5962343
If we subtract 0 from 460, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

The final outcome is 170311.5962343, with a leftover of 4.6e-07.
