1896 divided by 393 is 4 with a remainder of 324.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 1572 from 1896 to get 324.
Bring next digit (9) of the dividend behind the 324 and repeat the process: 3249 / 393

On to step 5:
If we divide 3249 by 393, we get 8 and a remainder of 105.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
Deduct 3144 from 3249 and we're left with 105.
Append the next digit (6) from the dividend to 105 and continue with: 1056 / 393

Advancing to step 6:
1056 divided by 393 is 2 with a remainder of 270.
Record the quotient 2 as the next digit in the result. 
Result so far: 482.0
If we take 786 away from 1056, we end up with 270.
Fetch the next digit (1) from the dividend, attach it to 270 and continue: 2701 / 393

On to step 7:
2701 divided by 393 is 6 with a remainder of 343.
Put 6 as the next digit of the answer. 
Result so far: 4826.0
Subtract 2358 from 2701 to get 343.
Bring next digit (9) of the dividend behind the 343 and repeat the process: 3439 / 393

Moving on to step 8:
When dividing 3439 by 393, we get 8 with a remainder of 295.
The number 8 becomes the next digit in our result. 
Result so far: 48268.0
Deduct 3144 from 3439 and we're left with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Advancing to step 9:
393 can be fit into 2950 7 times, resulting in a remainder of 199.
Use 7 as the next digit of our solution. 
Result so far: 48268.7
If we subtract 2751 from 2950, we get 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Step 10:
The number 393 fits into 1990 5 times, leaving a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 48268.75
The remainder is 25 after subtracting 1965 from 1990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 11:
393 goes into 250 0 times with a remainder of 250.
Use 0 as the next digit of our solution. 
Result so far: 48268.75
The remainder is 250 after subtracting 0 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 12:
393 goes into 2500 6 times with a remainder of 142.
The next digit of our result is 6. 
Result so far: 48268.7506
Subtract 2358 from 2500 to get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Going ahead to step 13:
The number 393 fits into 1420 3 times, leaving a remainder of 241.
Write down 3 as next digit of the result. 
Result so far: 48268.75063
Subtract 1179 from 1420 to get 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Advancing to step 14:
When dividing 2410 by 393, we get 6 with a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 48268.750636
Subtracting 2358 from 2410 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 15:
393 goes into 520 1 times with a remainder of 127.
Write down 1 as next digit of the result. 
Result so far: 48268.7506361
Deduct 393 from 520 and we're left with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Let's proceed to step 16:
393 can be fit into 1270 3 times, resulting in a remainder of 91.
Put 3 as the next digit of the answer. 
Result so far: 48268.75063613
Subtracting 1179 from 1270 leaves us with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Our division results in 48268.75063613 with a remaining 9.1e-08.
