17384694 divided by 399 
We want to divide 17384694 by 399.

Going ahead to step 1:
The number 399 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 399

Step 2:
When dividing 17 by 399, we get 0 with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Include the next digit (3) from the dividend after 17, then repeat: 173 / 399

Let's proceed to step 3:
399 can be fit into 173 0 times, resulting in a remainder of 173.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 173 after subtracting 0 from 173.
Take the next digit (8) from the dividend and append it to 173, then repeat: 1738 / 399

Let's proceed to step 4:
1738 divided by 399 is 4 with a remainder of 142.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 1596 from 1738 leaves us with 142.
Bring next digit (4) of the dividend behind the 142 and repeat the process: 1424 / 399

Let's proceed to step 5:
399 can be fit into 1424 3 times, resulting in a remainder of 227.
Write down 3 as next digit of the result. 
Result so far: 43.0
If we subtract 1197 from 1424, we get 227.
Bring next digit (6) of the dividend behind the 227 and repeat the process: 2276 / 399

Going ahead to step 6:
The number 399 fits into 2276 5 times, leaving a remainder of 281.
The number 5 becomes the next digit in our result. 
Result so far: 435.0
Subtracting 1995 from 2276 leaves us with 281.
Include the next digit (9) from the dividend after 281, then repeat: 2819 / 399

Moving on to step 7:
399 goes into 2819 7 times with a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 4357.0
The remainder is 26 after subtracting 2793 from 2819.
Bring next digit (4) of the dividend behind the 26 and repeat the process: 264 / 399

Going ahead to step 8:
399 can be fit into 264 0 times, resulting in a remainder of 264.
Use 0 as the next digit of our solution. 
Result so far: 43570.0
If we subtract 0 from 264, we get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Let's proceed to step 9:
399 goes into 2640 6 times with a remainder of 246.
Record the quotient 6 as the next digit in the result. 
Result so far: 43570.6
The remainder is 246 after subtracting 2394 from 2640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Step 10:
The number 399 fits into 2460 6 times, leaving a remainder of 66.
Record the quotient 6 as the next digit in the result. 
Result so far: 43570.66
If we take 2394 away from 2460, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The final result is 43570.66 with a remainder of 0.066.
