We're dividing 71870162 by 478 
We want to divide 71870162 by 478.

Moving on to step 1:
When dividing 7 by 478, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 478

Step 2:
If we divide 71 by 478, we get 0 and a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Take the next digit (8) from the dividend and append it to 71, then repeat: 718 / 478

Step 3:
478 can be fit into 718 1 times, resulting in a remainder of 240.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 478 from 718, we get 240.
Bring next digit (7) of the dividend behind the 240 and repeat the process: 2407 / 478

Advancing to step 4:
When dividing 2407 by 478, we get 5 with a remainder of 17.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 2390 away from 2407, we end up with 17.
Include the next digit (0) from the dividend after 17, then repeat: 170 / 478

Moving on to step 5:
When dividing 170 by 478, we get 0 with a remainder of 170.
Put 0 as the next digit of the answer. 
Result so far: 150.0
If we take 0 away from 170, we end up with 170.
Grab the next digit (1) from the dividend, add it to 170, then carry on: 1701 / 478

Moving on to step 6:
478 can be fit into 1701 3 times, resulting in a remainder of 267.
Write down 3 as next digit of the result. 
Result so far: 1503.0
Deduct 1434 from 1701 and we're left with 267.
Bring next digit (6) of the dividend behind the 267 and repeat the process: 2676 / 478

Advancing to step 7:
478 goes into 2676 5 times with a remainder of 286.
Record the quotient 5 as the next digit in the result. 
Result so far: 15035.0
If we subtract 2390 from 2676, we get 286.
Append the next digit (2) from the dividend to 286 and continue with: 2862 / 478

Moving on to step 8:
If we divide 2862 by 478, we get 5 and a remainder of 472.
Record the quotient 5 as the next digit in the result. 
Result so far: 150355.0
Subtract 2390 from 2862 to get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Moving on to step 9:
When dividing 4720 by 478, we get 9 with a remainder of 418.
The next digit of our result is 9. 
Result so far: 150355.9
The remainder is 418 after subtracting 4302 from 4720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

On to step 10:
478 can be fit into 4180 8 times, resulting in a remainder of 356.
Record the quotient 8 as the next digit in the result. 
Result so far: 150355.98
Deduct 3824 from 4180 and we're left with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Let's proceed to step 11:
3560 divided by 478 is 7 with a remainder of 214.
Record the quotient 7 as the next digit in the result. 
Result so far: 150355.987
Subtract 3346 from 3560 to get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Step 12:
The number 478 fits into 2140 4 times, leaving a remainder of 228.
Record the quotient 4 as the next digit in the result. 
Result so far: 150355.9874
Subtracting 1912 from 2140 leaves us with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 13:
The number 478 fits into 2280 4 times, leaving a remainder of 368.
The next digit of our result is 4. 
Result so far: 150355.98744
Subtract 1912 from 2280 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

The final outcome is 150355.98744, with a leftover of 0.000368.
