16138885 ÷ 886 
Let's see how many times 886 fits into 16138885.

Let's proceed to step 1:
1 divided by 886 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 886

Advancing to step 2:
If we divide 16 by 886, we get 0 and a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Grab the next digit (1) from the dividend, add it to 16, then carry on: 161 / 886

Advancing to step 3:
886 goes into 161 0 times with a remainder of 161.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 161 to get 161.
Fetch the next digit (3) from the dividend, attach it to 161 and continue: 1613 / 886

Step 4:
When dividing 1613 by 886, we get 1 with a remainder of 727.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 727 after subtracting 886 from 1613.
Append the next digit (8) from the dividend to 727 and continue with: 7278 / 886

Moving on to step 5:
If we divide 7278 by 886, we get 8 and a remainder of 190.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtract 7088 from 7278 to get 190.
Grab the next digit (8) from the dividend, add it to 190, then carry on: 1908 / 886

Moving on to step 6:
If we divide 1908 by 886, we get 2 and a remainder of 136.
The next digit of our result is 2. 
Result so far: 182.0
Subtract 1772 from 1908 to get 136.
Take the next digit (8) from the dividend and append it to 136, then repeat: 1368 / 886

Let's proceed to step 7:
886 can be fit into 1368 1 times, resulting in a remainder of 482.
The next digit of our result is 1. 
Result so far: 1821.0
Subtract 886 from 1368 to get 482.
Fetch the next digit (5) from the dividend, attach it to 482 and continue: 4825 / 886

Step 8:
The number 886 fits into 4825 5 times, leaving a remainder of 395.
The next digit of our result is 5. 
Result so far: 18215.0
If we subtract 4430 from 4825, we get 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Moving on to step 9:
When dividing 3950 by 886, we get 4 with a remainder of 406.
The next digit of our result is 4. 
Result so far: 18215.4
If we take 3544 away from 3950, we end up with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

On to step 10:
886 can be fit into 4060 4 times, resulting in a remainder of 516.
Use 4 as the next digit of our solution. 
Result so far: 18215.44
Deduct 3544 from 4060 and we're left with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Our division results in 18215.44 with a remaining 0.516.
