We divide 31390 by 16
We want to figure out the number of times 31390 can be divided by 16.

Let's proceed to step 1:
If we divide 3 by 16, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 16

Let's proceed to step 2:
The number 16 fits into 31 1 times, leaving a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 16 from 31 to get 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 16

Moving on to step 3:
The number 16 fits into 153 9 times, leaving a remainder of 9.
The next digit of our result is 9. 
Result so far: 19.0
If we subtract 144 from 153, we get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 16

Step 4:
16 goes into 99 6 times with a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 196.0
Subtracting 96 from 99 leaves us with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 16

Going ahead to step 5:
The number 16 fits into 30 1 times, leaving a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 1961.0
The remainder is 14 after subtracting 16 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 6:
16 can be fit into 140 8 times, resulting in a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 1961.8
Deduct 128 from 140 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
16 goes into 120 7 times with a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 1961.87
If we take 112 away from 120, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
16 goes into 80 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 1961.875
Subtract 80 from 80 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
If we divide 0 by 16, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1961.875
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
16 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1961.875
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 1961.875 and a remainder of 0.0.
