17214487 ÷ 873 
We're looking to find how many times 873 goes into 17214487.

Moving on to step 1:
873 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 873

Let's proceed to step 2:
The number 873 fits into 17 0 times, leaving a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 873

On to step 3:
172 divided by 873 is 0 with a remainder of 172.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 172, we end up with 172.
Take the next digit (1) from the dividend and append it to 172, then repeat: 1721 / 873

Let's proceed to step 4:
873 goes into 1721 1 times with a remainder of 848.
The next digit of our result is 1. 
Result so far: 1.0
If we take 873 away from 1721, we end up with 848.
Fetch the next digit (4) from the dividend, attach it to 848 and continue: 8484 / 873

Going ahead to step 5:
8484 divided by 873 is 9 with a remainder of 627.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtract 7857 from 8484 to get 627.
Include the next digit (4) from the dividend after 627, then repeat: 6274 / 873

Let's proceed to step 6:
The number 873 fits into 6274 7 times, leaving a remainder of 163.
Write down 7 as next digit of the result. 
Result so far: 197.0
Subtract 6111 from 6274 to get 163.
Take the next digit (8) from the dividend and append it to 163, then repeat: 1638 / 873

Moving on to step 7:
1638 divided by 873 is 1 with a remainder of 765.
Use 1 as the next digit of our solution. 
Result so far: 1971.0
Subtracting 873 from 1638 leaves us with 765.
Take the next digit (7) from the dividend and append it to 765, then repeat: 7657 / 873

Going ahead to step 8:
The number 873 fits into 7657 8 times, leaving a remainder of 673.
Use 8 as the next digit of our solution. 
Result so far: 19718.0
Subtract 6984 from 7657 to get 673.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6730, and continue the process.

Let's proceed to step 9:
873 can be fit into 6730 7 times, resulting in a remainder of 619.
Put 7 as the next digit of the answer. 
Result so far: 19718.7
Subtracting 6111 from 6730 leaves us with 619.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6190, and continue the process.

Let's proceed to step 10:
6190 divided by 873 is 7 with a remainder of 79.
Write down 7 as next digit of the result. 
Result so far: 19718.77
If we take 6111 away from 6190, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

The final outcome is 19718.77, with a leftover of 0.079.
