We're dividing 77571 by 16 
We want to divide 77571 by 16.

Step 1:
16 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 16

Moving on to step 2:
If we divide 77 by 16, we get 4 and a remainder of 13.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 64 from 77 leaves us with 13.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 16

Step 3:
135 divided by 16 is 8 with a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 48.0
Subtract 128 from 135 to get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 16

Advancing to step 4:
The number 16 fits into 77 4 times, leaving a remainder of 13.
Write down 4 as next digit of the result. 
Result so far: 484.0
The remainder is 13 after subtracting 64 from 77.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 16

Let's proceed to step 5:
When dividing 131 by 16, we get 8 with a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 4848.0
The remainder is 3 after subtracting 128 from 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 6:
When dividing 30 by 16, we get 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 4848.1
If we subtract 16 from 30, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 7:
When dividing 140 by 16, we get 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 4848.18
Subtract 128 from 140 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 8:
The number 16 fits into 120 7 times, leaving a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 4848.187
If we subtract 112 from 120, we 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.

Let's proceed to step 9:
80 divided by 16 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 4848.1875
If we take 80 away from 80, 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.

Moving on to step 10:
0 divided by 16 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4848.1875
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.

Advancing to step 11:
When dividing 0 by 16, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4848.1875
Subtract 0 from 0 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.

The final result is 4848.1875 with a remainder of 0.0.
