20469880 ÷ 16 
Let's see how many times 16 fits into 20469880.

Going ahead to step 1:
16 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 16

Step 2:
If we divide 20 by 16, we get 1 and a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 16 away from 20, we end up with 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 16

Moving on to step 3:
If we divide 44 by 16, we get 2 and a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 12 after subtracting 32 from 44.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 16

Advancing to step 4:
When dividing 126 by 16, we get 7 with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 127.0
Subtracting 112 from 126 leaves us with 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 16

Going ahead to step 5:
When dividing 149 by 16, we get 9 with a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 1279.0
Subtract 144 from 149 to get 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 16

Advancing to step 6:
58 divided by 16 is 3 with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 12793.0
Deduct 48 from 58 and we're left with 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 16

On to step 7:
The number 16 fits into 108 6 times, leaving a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 127936.0
Deduct 96 from 108 and we're left with 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 16

Going ahead to step 8:
If we divide 120 by 16, we get 7 and a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 1279367.0
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.

Moving on to step 9:
16 can be fit into 80 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 1279367.5
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.

Step 10:
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: 1279367.5
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.

Advancing to step 11:
When dividing 0 by 16, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1279367.5
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.

In conclusion, the division gives 1279367.5 with a balance of 0.0.
