We're dividing 77603873 by 478 
We're looking to find how many times 478 goes into 77603873.

On to step 1:
If we divide 7 by 478, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 478

Step 2:
478 can be fit into 77 0 times, resulting in a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Take the next digit (6) from the dividend and append it to 77, then repeat: 776 / 478

Going ahead to step 3:
When dividing 776 by 478, we get 1 with a remainder of 298.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 478 from 776 to get 298.
Fetch the next digit (0) from the dividend, attach it to 298 and continue: 2980 / 478

Moving on to step 4:
478 goes into 2980 6 times with a remainder of 112.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
The remainder is 112 after subtracting 2868 from 2980.
Append the next digit (3) from the dividend to 112 and continue with: 1123 / 478

On to step 5:
478 goes into 1123 2 times with a remainder of 167.
Put 2 as the next digit of the answer. 
Result so far: 162.0
Deduct 956 from 1123 and we're left with 167.
Append the next digit (8) from the dividend to 167 and continue with: 1678 / 478

Step 6:
If we divide 1678 by 478, we get 3 and a remainder of 244.
Write down 3 as next digit of the result. 
Result so far: 1623.0
Subtracting 1434 from 1678 leaves us with 244.
Fetch the next digit (7) from the dividend, attach it to 244 and continue: 2447 / 478

Step 7:
478 can be fit into 2447 5 times, resulting in a remainder of 57.
Put 5 as the next digit of the answer. 
Result so far: 16235.0
If we subtract 2390 from 2447, we get 57.
Append the next digit (3) from the dividend to 57 and continue with: 573 / 478

Advancing to step 8:
If we divide 573 by 478, we get 1 and a remainder of 95.
Put 1 as the next digit of the answer. 
Result so far: 162351.0
Subtract 478 from 573 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Step 9:
950 divided by 478 is 1 with a remainder of 472.
Record the quotient 1 as the next digit in the result. 
Result so far: 162351.1
Deduct 478 from 950 and we're left with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Let's proceed to step 10:
If we divide 4720 by 478, we get 9 and a remainder of 418.
Use 9 as the next digit of our solution. 
Result so far: 162351.19
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.

Step 11:
If we divide 4180 by 478, we get 8 and a remainder of 356.
Put 8 as the next digit of the answer. 
Result so far: 162351.198
Subtracting 3824 from 4180 leaves us 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.

On to step 12:
3560 divided by 478 is 7 with a remainder of 214.
Use 7 as the next digit of our solution. 
Result so far: 162351.1987
If we subtract 3346 from 3560, we 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.

Moving on to step 13:
478 goes into 2140 4 times with a remainder of 228.
Write down 4 as next digit of the result. 
Result so far: 162351.19874
The remainder is 228 after subtracting 1912 from 2140.
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 14:
478 goes into 2280 4 times with a remainder of 368.
Record the quotient 4 as the next digit in the result. 
Result so far: 162351.198744
The remainder is 368 after subtracting 1912 from 2280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

After the division, we end up with 162351.198744 and a remainder of 3.68e-05.
