We divide 258519 by 16
Our goal is to divide 258519 by 16.

Step 1:
16 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 16

On to step 2:
16 goes into 25 1 times with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 16 away from 25, we end up with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 16

Step 3:
16 can be fit into 98 6 times, resulting in a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we take 96 away from 98, we end up with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 16

Let's proceed to step 4:
16 can be fit into 25 1 times, resulting in a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 161.0
The remainder is 9 after subtracting 16 from 25.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 16

Step 5:
16 goes into 91 5 times with a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 1615.0
Subtracting 80 from 91 leaves us with 11.
Grab the next digit (9) from the dividend, add it to 11, then carry on: 119 / 16

On to step 6:
If we divide 119 by 16, we get 7 and a remainder of 7.
The next digit of our result is 7. 
Result so far: 16157.0
If we take 112 away from 119, we end up 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.

Let's proceed to step 7:
70 divided by 16 is 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 16157.4
If we subtract 64 from 70, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
16 goes into 60 3 times with a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 16157.43
Subtracting 48 from 60 leaves us 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.

Advancing to step 9:
120 divided by 16 is 7 with a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 16157.437
Subtract 112 from 120 to get 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 10:
The number 16 fits into 80 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 16157.4375
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.

On to step 11:
0 divided by 16 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 16157.4375
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.

Let's proceed to step 12:
16 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 16157.4375
If we take 0 away from 0, we end up 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.

The quotient of the division is 16157.4375, and the remainder is 0.0.
