We look at the division of 80103739 by 478 
We're looking to find how many times 478 goes into 80103739.

Moving on to step 1:
If we divide 8 by 478, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 478

Step 2:
If we divide 80 by 478, we get 0 and a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Include the next digit (1) from the dividend after 80, then repeat: 801 / 478

Going ahead to step 3:
If we divide 801 by 478, we get 1 and a remainder of 323.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 478 from 801 leaves us with 323.
Include the next digit (0) from the dividend after 323, then repeat: 3230 / 478

Let's proceed to step 4:
478 goes into 3230 6 times with a remainder of 362.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtracting 2868 from 3230 leaves us with 362.
Include the next digit (3) from the dividend after 362, then repeat: 3623 / 478

Going ahead to step 5:
3623 divided by 478 is 7 with a remainder of 277.
Use 7 as the next digit of our solution. 
Result so far: 167.0
Subtracting 3346 from 3623 leaves us with 277.
Append the next digit (7) from the dividend to 277 and continue with: 2777 / 478

Let's proceed to step 6:
The number 478 fits into 2777 5 times, leaving a remainder of 387.
Write down 5 as next digit of the result. 
Result so far: 1675.0
If we subtract 2390 from 2777, we get 387.
Take the next digit (3) from the dividend and append it to 387, then repeat: 3873 / 478

Advancing to step 7:
478 goes into 3873 8 times with a remainder of 49.
Write down 8 as next digit of the result. 
Result so far: 16758.0
If we subtract 3824 from 3873, we get 49.
Append the next digit (9) from the dividend to 49 and continue with: 499 / 478

Going ahead to step 8:
499 divided by 478 is 1 with a remainder of 21.
The next digit of our result is 1. 
Result so far: 167581.0
Subtracting 478 from 499 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 9:
478 goes into 210 0 times with a remainder of 210.
Write down 0 as next digit of the result. 
Result so far: 167581.0
Subtracting 0 from 210 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 10:
478 can be fit into 2100 4 times, resulting in a remainder of 188.
Use 4 as the next digit of our solution. 
Result so far: 167581.04
Deduct 1912 from 2100 and we're left with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Let's proceed to step 11:
When dividing 1880 by 478, we get 3 with a remainder of 446.
The next digit of our result is 3. 
Result so far: 167581.043
If we take 1434 away from 1880, we end up with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

On to step 12:
4460 divided by 478 is 9 with a remainder of 158.
Put 9 as the next digit of the answer. 
Result so far: 167581.0439
The remainder is 158 after subtracting 4302 from 4460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Advancing to step 13:
1580 divided by 478 is 3 with a remainder of 146.
Put 3 as the next digit of the answer. 
Result so far: 167581.04393
Subtracting 1434 from 1580 leaves us with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Step 14:
The number 478 fits into 1460 3 times, leaving a remainder of 26.
Write down 3 as next digit of the result. 
Result so far: 167581.043933
The remainder is 26 after subtracting 1434 from 1460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Our division results in 167581.043933 with a remaining 2.6e-06.
