176991 ÷ 16 
We're looking to find how many times 16 goes into 176991.

Going ahead to step 1:
1 divided by 16 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 16

Step 2:
The number 16 fits into 17 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 16 from 17, we get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 16

Let's proceed to step 3:
If we divide 16 by 16, we get 1 and a remainder of 0.
The next digit of our result is 1. 
Result so far: 11.0
If we take 16 away from 16, we end up with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 16

On to step 4:
If we divide 9 by 16, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 110.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 16

Going ahead to step 5:
16 goes into 99 6 times with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 1106.0
The remainder is 3 after subtracting 96 from 99.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 16

Going ahead to step 6:
16 goes into 31 1 times with a remainder of 15.
The next digit of our result is 1. 
Result so far: 11061.0
Deduct 16 from 31 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
16 can be fit into 150 9 times, resulting in a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 11061.9
Deduct 144 from 150 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
16 can be fit into 60 3 times, resulting in a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 11061.93
The remainder is 12 after subtracting 48 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
If we divide 120 by 16, we get 7 and a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 11061.937
The remainder is 8 after subtracting 112 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
16 goes into 80 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 11061.9375
Subtracting 80 from 80 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.

On to step 11:
When dividing 0 by 16, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 11061.9375
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.

Step 12:
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: 11061.9375
If we subtract 0 from 0, we 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 outcome is 11061.9375, with a leftover of 0.0.
