16138287 ÷ 872 
We're looking to find how many times 872 goes into 16138287.

Advancing to step 1:
If we divide 1 by 872, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 872

On to step 2:
The number 872 fits into 16 0 times, leaving a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Grab the next digit (1) from the dividend, add it to 16, then carry on: 161 / 872

Moving on to step 3:
161 divided by 872 is 0 with a remainder of 161.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 161 leaves us with 161.
Include the next digit (3) from the dividend after 161, then repeat: 1613 / 872

Going ahead to step 4:
872 can be fit into 1613 1 times, resulting in a remainder of 741.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 872 from 1613 to get 741.
Include the next digit (8) from the dividend after 741, then repeat: 7418 / 872

Advancing to step 5:
If we divide 7418 by 872, we get 8 and a remainder of 442.
The next digit of our result is 8. 
Result so far: 18.0
If we subtract 6976 from 7418, we get 442.
Append the next digit (2) from the dividend to 442 and continue with: 4422 / 872

On to step 6:
4422 divided by 872 is 5 with a remainder of 62.
Write down 5 as next digit of the result. 
Result so far: 185.0
Deduct 4360 from 4422 and we're left with 62.
Append the next digit (8) from the dividend to 62 and continue with: 628 / 872

Advancing to step 7:
The number 872 fits into 628 0 times, leaving a remainder of 628.
Put 0 as the next digit of the answer. 
Result so far: 1850.0
If we subtract 0 from 628, we get 628.
Append the next digit (7) from the dividend to 628 and continue with: 6287 / 872

On to step 8:
6287 divided by 872 is 7 with a remainder of 183.
Use 7 as the next digit of our solution. 
Result so far: 18507.0
If we subtract 6104 from 6287, we get 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Step 9:
If we divide 1830 by 872, we get 2 and a remainder of 86.
Use 2 as the next digit of our solution. 
Result so far: 18507.2
Deduct 1744 from 1830 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 10:
860 divided by 872 is 0 with a remainder of 860.
Write down 0 as next digit of the result. 
Result so far: 18507.2
If we subtract 0 from 860, we get 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

Advancing to step 11:
If we divide 8600 by 872, we get 9 and a remainder of 752.
Write down 9 as next digit of the result. 
Result so far: 18507.209
The remainder is 752 after subtracting 7848 from 8600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

On to step 12:
872 goes into 7520 8 times with a remainder of 544.
Write down 8 as next digit of the result. 
Result so far: 18507.2098
If we take 6976 away from 7520, we end up with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Moving on to step 13:
5440 divided by 872 is 6 with a remainder of 208.
Write down 6 as next digit of the result. 
Result so far: 18507.20986
If we subtract 5232 from 5440, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 14:
If we divide 2080 by 872, we get 2 and a remainder of 336.
The number 2 becomes the next digit in our result. 
Result so far: 18507.209862
The remainder is 336 after subtracting 1744 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Step 15:
When dividing 3360 by 872, we get 3 with a remainder of 744.
The next digit of our result is 3. 
Result so far: 18507.2098623
Subtract 2616 from 3360 to get 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

Moving on to step 16:
872 can be fit into 7440 8 times, resulting in a remainder of 464.
The number 8 becomes the next digit in our result. 
Result so far: 18507.20986238
If we subtract 6976 from 7440, we get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

The final outcome is 18507.20986238, with a leftover of 4.64e-07.
