478 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 478

Moving on to step 2:
The number 478 fits into 81 0 times, leaving 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.
Fetch the next digit (3) from the dividend, attach it to 81 and continue: 813 / 478

Advancing to step 3:
The number 478 fits into 813 1 times, leaving a remainder of 335.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 478 from 813 to get 335.
Grab the next digit (5) from the dividend, add it to 335, then carry on: 3355 / 478

Going ahead to step 4:
The number 478 fits into 3355 7 times, leaving a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtract 3346 from 3355 to get 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 478

On to step 5:
If we divide 90 by 478, we get 0 and a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 170.0
Deduct 0 from 90 and we're left with 90.
Bring next digit (6) of the dividend behind the 90 and repeat the process: 906 / 478

Moving on to step 6:
478 can be fit into 906 1 times, resulting in a remainder of 428.
The number 1 becomes the next digit in our result. 
Result so far: 1701.0
The remainder is 428 after subtracting 478 from 906.
Include the next digit (6) from the dividend after 428, then repeat: 4286 / 478

On to step 7:
The number 478 fits into 4286 8 times, leaving a remainder of 462.
The next digit of our result is 8. 
Result so far: 17018.0
If we take 3824 away from 4286, we end up with 462.
Grab the next digit (4) from the dividend, add it to 462, then carry on: 4624 / 478

On to step 8:
When dividing 4624 by 478, we get 9 with a remainder of 322.
Record the quotient 9 as the next digit in the result. 
Result so far: 170189.0
If we take 4302 away from 4624, we end up with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Moving on to step 9:
478 can be fit into 3220 6 times, resulting in a remainder of 352.
Use 6 as the next digit of our solution. 
Result so far: 170189.6
If we subtract 2868 from 3220, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Moving on to step 10:
3520 divided by 478 is 7 with a remainder of 174.
Write down 7 as next digit of the result. 
Result so far: 170189.67
If we subtract 3346 from 3520, we get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Step 11:
1740 divided by 478 is 3 with a remainder of 306.
Write down 3 as next digit of the result. 
Result so far: 170189.673
If we take 1434 away from 1740, we end up with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Going ahead to step 12:
The number 478 fits into 3060 6 times, leaving a remainder of 192.
The number 6 becomes the next digit in our result. 
Result so far: 170189.6736
The remainder is 192 after subtracting 2868 from 3060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 13:
When dividing 1920 by 478, we get 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 170189.67364
Subtracting 1912 from 1920 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 14:
When dividing 80 by 478, we get 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 170189.67364
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 15:
When dividing 800 by 478, we get 1 with a remainder of 322.
Use 1 as the next digit of our solution. 
Result so far: 170189.6736401
The remainder is 322 after subtracting 478 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Let's proceed to step 16:
When dividing 3220 by 478, we get 6 with a remainder of 352.
The next digit of our result is 6. 
Result so far: 170189.67364016
Subtract 2868 from 3220 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

The final outcome is 170189.67364016, with a leftover of 3.52e-07.
