We're dividing 12380229 by 478 
We want to divide 12380229 by 478.

Let's proceed to step 1:
1 divided by 478 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 478

On to step 2:
478 goes into 12 0 times with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 478

Step 3:
If we divide 123 by 478, we get 0 and a remainder of 123.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 123 and we're left with 123.
Take the next digit (8) from the dividend and append it to 123, then repeat: 1238 / 478

Moving on to step 4:
1238 divided by 478 is 2 with a remainder of 282.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 956 from 1238 to get 282.
Include the next digit (0) from the dividend after 282, then repeat: 2820 / 478

Let's proceed to step 5:
The number 478 fits into 2820 5 times, leaving a remainder of 430.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtract 2390 from 2820 to get 430.
Grab the next digit (2) from the dividend, add it to 430, then carry on: 4302 / 478

On to step 6:
If we divide 4302 by 478, we get 9 and a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 259.0
Subtract 4302 from 4302 to get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 478

Let's proceed to step 7:
478 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 2590.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 478

Going ahead to step 8:
If we divide 29 by 478, we get 0 and a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 25900.0
If we subtract 0 from 29, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 9:
If we divide 290 by 478, we get 0 and a remainder of 290.
Write down 0 as next digit of the result. 
Result so far: 25900.0
Subtract 0 from 290 to get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 10:
478 goes into 2900 6 times with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 25900.06
If we subtract 2868 from 2900, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 11:
478 goes into 320 0 times with a remainder of 320.
Use 0 as the next digit of our solution. 
Result so far: 25900.06
If we take 0 away from 320, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 12:
When dividing 3200 by 478, we get 6 with a remainder of 332.
The next digit of our result is 6. 
Result so far: 25900.0606
Subtract 2868 from 3200 to get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Advancing to step 13:
The number 478 fits into 3320 6 times, leaving a remainder of 452.
The number 6 becomes the next digit in our result. 
Result so far: 25900.06066
Subtract 2868 from 3320 to get 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

The final outcome is 25900.06066, with a leftover of 0.000452.
