73301860 ÷ 215 
We want to figure out the number of times 73301860 can be divided by 215.

Advancing to step 1:
215 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 215

Let's proceed to step 2:
If we divide 73 by 215, we get 0 and a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 73, we end up with 73.
Include the next digit (3) from the dividend after 73, then repeat: 733 / 215

Step 3:
When dividing 733 by 215, we get 3 with a remainder of 88.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 645 from 733 and we're left with 88.
Append the next digit (0) from the dividend to 88 and continue with: 880 / 215

Advancing to step 4:
880 divided by 215 is 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
Subtract 860 from 880 to get 20.
Grab the next digit (1) from the dividend, add it to 20, then carry on: 201 / 215

Going ahead to step 5:
When dividing 201 by 215, we get 0 with a remainder of 201.
The number 0 becomes the next digit in our result. 
Result so far: 340.0
If we take 0 away from 201, we end up with 201.
Include the next digit (8) from the dividend after 201, then repeat: 2018 / 215

Step 6:
215 goes into 2018 9 times with a remainder of 83.
The next digit of our result is 9. 
Result so far: 3409.0
If we subtract 1935 from 2018, we get 83.
Append the next digit (6) from the dividend to 83 and continue with: 836 / 215

Moving on to step 7:
The number 215 fits into 836 3 times, leaving a remainder of 191.
Record the quotient 3 as the next digit in the result. 
Result so far: 34093.0
Subtracting 645 from 836 leaves us with 191.
Bring next digit (0) of the dividend behind the 191 and repeat the process: 1910 / 215

Moving on to step 8:
215 goes into 1910 8 times with a remainder of 190.
Record the quotient 8 as the next digit in the result. 
Result so far: 340938.0
Subtracting 1720 from 1910 leaves us 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.

Advancing to step 9:
If we divide 1900 by 215, we get 8 and a remainder of 180.
Use 8 as the next digit of our solution. 
Result so far: 340938.8
If we subtract 1720 from 1900, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 10:
If we divide 1800 by 215, we get 8 and a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 340938.88
Deduct 1720 from 1800 and we're left 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.

Our division results in 340938.88 with a remaining 0.08.
