12988088 ÷ 16 
We want to figure out the number of times 12988088 can be divided by 16.

Step 1:
The number 16 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 16

Let's proceed to step 2:
12 divided by 16 is 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 16

Going ahead to step 3:
16 goes into 129 8 times with a remainder of 1.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 1 after subtracting 128 from 129.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 16

Going ahead to step 4:
If we divide 18 by 16, we get 1 and a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 81.0
Deduct 16 from 18 and we're left with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 16

Advancing to step 5:
When dividing 28 by 16, we get 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 811.0
If we subtract 16 from 28, we get 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 16

Let's proceed to step 6:
If we divide 120 by 16, we get 7 and a remainder of 8.
The next digit of our result is 7. 
Result so far: 8117.0
Deduct 112 from 120 and we're left with 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 16

Moving on to step 7:
16 can be fit into 88 5 times, resulting in a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 81175.0
Subtract 80 from 88 to get 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 16

Moving on to step 8:
16 can be fit into 88 5 times, resulting in a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 811755.0
Subtracting 80 from 88 leaves us 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.

Step 9:
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: 811755.5
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.

Going ahead to step 10:
0 divided by 16 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 811755.5
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.

Moving on to step 11:
16 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 811755.5
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 quotient of the division is 811755.5, and the remainder is 0.0.
