We're dividing 17298502 by 215 
We want to figure out the number of times 17298502 can be divided by 215.

On to step 1:
1 divided by 215 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 215

Going ahead to step 2:
When dividing 17 by 215, we get 0 with 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.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 215

On to step 3:
If we divide 172 by 215, we get 0 and a remainder of 172.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 172, we get 172.
Bring next digit (9) of the dividend behind the 172 and repeat the process: 1729 / 215

Advancing to step 4:
When dividing 1729 by 215, we get 8 with a remainder of 9.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 1720 from 1729 leaves us with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 215

Moving on to step 5:
The number 215 fits into 98 0 times, leaving a remainder of 98.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
If we take 0 away from 98, we end up with 98.
Take the next digit (5) from the dividend and append it to 98, then repeat: 985 / 215

Moving on to step 6:
215 can be fit into 985 4 times, resulting in a remainder of 125.
Write down 4 as next digit of the result. 
Result so far: 804.0
Subtracting 860 from 985 leaves us with 125.
Grab the next digit (0) from the dividend, add it to 125, then carry on: 1250 / 215

Advancing to step 7:
1250 divided by 215 is 5 with a remainder of 175.
The number 5 becomes the next digit in our result. 
Result so far: 8045.0
Subtract 1075 from 1250 to get 175.
Grab the next digit (2) from the dividend, add it to 175, then carry on: 1752 / 215

Moving on to step 8:
If we divide 1752 by 215, we get 8 and a remainder of 32.
The next digit of our result is 8. 
Result so far: 80458.0
If we take 1720 away from 1752, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 9:
215 can be fit into 320 1 times, resulting in a remainder of 105.
The number 1 becomes the next digit in our result. 
Result so far: 80458.1
The remainder is 105 after subtracting 215 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Step 10:
215 goes into 1050 4 times with a remainder of 190.
Put 4 as the next digit of the answer. 
Result so far: 80458.14
Deduct 860 from 1050 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 11:
1900 divided by 215 is 8 with a remainder of 180.
Use 8 as the next digit of our solution. 
Result so far: 80458.148
Deduct 1720 from 1900 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 12:
215 goes into 1800 8 times with a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 80458.1488
If we take 1720 away from 1800, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final outcome is 80458.1488, with a leftover of 0.0008.
