We're dividing 31399 by 48 
We're looking to find how many times 48 goes into 31399.

Going ahead to step 1:
When dividing 3 by 48, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 48

On to step 2:
If we divide 31 by 48, we get 0 and a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Bring next digit (3) of the dividend behind the 31 and repeat the process: 313 / 48

Step 3:
313 divided by 48 is 6 with a remainder of 25.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 288 from 313 leaves us with 25.
Fetch the next digit (9) from the dividend, attach it to 25 and continue: 259 / 48

Step 4:
The number 48 fits into 259 5 times, leaving a remainder of 19.
Use 5 as the next digit of our solution. 
Result so far: 65.0
Subtract 240 from 259 to get 19.
Take the next digit (9) from the dividend and append it to 19, then repeat: 199 / 48

Going ahead to step 5:
199 divided by 48 is 4 with a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 654.0
Subtracting 192 from 199 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 6:
48 can be fit into 70 1 times, resulting in a remainder of 22.
The next digit of our result is 1. 
Result so far: 654.1
The remainder is 22 after subtracting 48 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 7:
When dividing 220 by 48, we get 4 with a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 654.14
Subtract 192 from 220 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 8:
If we divide 280 by 48, we get 5 and a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 654.145
If we take 240 away from 280, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
48 can be fit into 400 8 times, resulting in a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 654.1458
If we subtract 384 from 400, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 10:
When dividing 160 by 48, we get 3 with a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 654.14583
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
160 divided by 48 is 3 with a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 654.145833
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 654.145833 with a balance of 1.6e-06.
