We look at the division of 73399318 by 215 
We want to figure out the number of times 73399318 can be divided by 215.

Moving on to step 1:
When dividing 7 by 215, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 215

Step 2:
When dividing 73 by 215, we get 0 with a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Append the next digit (3) from the dividend to 73 and continue with: 733 / 215

On to step 3:
The number 215 fits into 733 3 times, leaving a remainder of 88.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 88 after subtracting 645 from 733.
Fetch the next digit (9) from the dividend, attach it to 88 and continue: 889 / 215

Step 4:
215 goes into 889 4 times with a remainder of 29.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
Subtracting 860 from 889 leaves us with 29.
Take the next digit (9) from the dividend and append it to 29, then repeat: 299 / 215

Step 5:
When dividing 299 by 215, we get 1 with a remainder of 84.
Record the quotient 1 as the next digit in the result. 
Result so far: 341.0
If we take 215 away from 299, we end up with 84.
Take the next digit (3) from the dividend and append it to 84, then repeat: 843 / 215

Step 6:
215 can be fit into 843 3 times, resulting in a remainder of 198.
Record the quotient 3 as the next digit in the result. 
Result so far: 3413.0
The remainder is 198 after subtracting 645 from 843.
Bring next digit (1) of the dividend behind the 198 and repeat the process: 1981 / 215

Let's proceed to step 7:
If we divide 1981 by 215, we get 9 and a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 34139.0
Subtract 1935 from 1981 to get 46.
Include the next digit (8) from the dividend after 46, then repeat: 468 / 215

Going ahead to step 8:
The number 215 fits into 468 2 times, leaving a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 341392.0
If we take 430 away from 468, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 9:
If we divide 380 by 215, we get 1 and a remainder of 165.
The number 1 becomes the next digit in our result. 
Result so far: 341392.1
The remainder is 165 after subtracting 215 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Moving on to step 10:
215 goes into 1650 7 times with a remainder of 145.
Use 7 as the next digit of our solution. 
Result so far: 341392.17
Subtract 1505 from 1650 to get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Moving on to step 11:
The number 215 fits into 1450 6 times, leaving a remainder of 160.
Put 6 as the next digit of the answer. 
Result so far: 341392.176
Deduct 1290 from 1450 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 12:
215 goes into 1600 7 times with a remainder of 95.
Write down 7 as next digit of the result. 
Result so far: 341392.1767
If we subtract 1505 from 1600, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 13:
The number 215 fits into 950 4 times, leaving a remainder of 90.
Write down 4 as next digit of the result. 
Result so far: 341392.17674
Deduct 860 from 950 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 14:
215 goes into 900 4 times with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 341392.176744
Subtract 860 from 900 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 341392.176744 with a remaining 4e-06.
