573949 ÷ 16 
We want to figure out the number of times 573949 can be divided by 16.

On to step 1:
When dividing 5 by 16, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 16

Moving on to step 2:
If we divide 57 by 16, we get 3 and a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 48 from 57 leaves us with 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 16

Moving on to step 3:
The number 16 fits into 93 5 times, leaving a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 35.0
Subtract 80 from 93 to get 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 16

Advancing to step 4:
16 goes into 139 8 times with a remainder of 11.
The next digit of our result is 8. 
Result so far: 358.0
The remainder is 11 after subtracting 128 from 139.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 16

Advancing to step 5:
The number 16 fits into 114 7 times, leaving a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 3587.0
Subtract 112 from 114 to get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 16

Going ahead to step 6:
16 goes into 29 1 times with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 35871.0
If we subtract 16 from 29, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
If we divide 130 by 16, we get 8 and a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 35871.8
If we take 128 away from 130, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
When dividing 20 by 16, we get 1 with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 35871.81
If we subtract 16 from 20, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
If we divide 40 by 16, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 35871.812
If we take 32 away from 40, 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.

Going ahead to step 10:
If we divide 80 by 16, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 35871.8125
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.

Going ahead to step 11:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 35871.8125
Subtracting 0 from 0 leaves us 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.

Going ahead to step 12:
16 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 35871.8125
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 35871.8125, and the remainder is 0.0.
