We're dividing 14978515 by 399 
Our goal is to divide 14978515 by 399.

Going ahead to step 1:
399 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 399

Going ahead to step 2:
14 divided by 399 is 0 with a remainder of 14.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 399

Let's proceed to step 3:
If we divide 149 by 399, we get 0 and a remainder of 149.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 149 to get 149.
Append the next digit (7) from the dividend to 149 and continue with: 1497 / 399

Moving on to step 4:
399 goes into 1497 3 times with a remainder of 300.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 1197 from 1497 leaves us with 300.
Fetch the next digit (8) from the dividend, attach it to 300 and continue: 3008 / 399

Step 5:
399 goes into 3008 7 times with a remainder of 215.
The next digit of our result is 7. 
Result so far: 37.0
Deduct 2793 from 3008 and we're left with 215.
Append the next digit (5) from the dividend to 215 and continue with: 2155 / 399

Going ahead to step 6:
399 goes into 2155 5 times with a remainder of 160.
Write down 5 as next digit of the result. 
Result so far: 375.0
The remainder is 160 after subtracting 1995 from 2155.
Bring next digit (1) of the dividend behind the 160 and repeat the process: 1601 / 399

Going ahead to step 7:
399 can be fit into 1601 4 times, resulting in a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 3754.0
The remainder is 5 after subtracting 1596 from 1601.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 399

Advancing to step 8:
When dividing 55 by 399, we get 0 with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 37540.0
If we take 0 away from 55, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 9:
399 can be fit into 550 1 times, resulting in a remainder of 151.
Put 1 as the next digit of the answer. 
Result so far: 37540.1
Subtract 399 from 550 to get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Step 10:
1510 divided by 399 is 3 with a remainder of 313.
Put 3 as the next digit of the answer. 
Result so far: 37540.13
If we take 1197 away from 1510, we end up with 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Going ahead to step 11:
When dividing 3130 by 399, we get 7 with a remainder of 337.
The next digit of our result is 7. 
Result so far: 37540.137
If we subtract 2793 from 3130, we get 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Moving on to step 12:
399 goes into 3370 8 times with a remainder of 178.
Write down 8 as next digit of the result. 
Result so far: 37540.1378
The remainder is 178 after subtracting 3192 from 3370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Going ahead to step 13:
399 can be fit into 1780 4 times, resulting in a remainder of 184.
Write down 4 as next digit of the result. 
Result so far: 37540.13784
The remainder is 184 after subtracting 1596 from 1780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 14:
When dividing 1840 by 399, we get 4 with a remainder of 244.
Write down 4 as next digit of the result. 
Result so far: 37540.137844
If we subtract 1596 from 1840, we get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

After the division, we end up with 37540.137844 and a remainder of 2.44e-05.
