73166680 ÷ 215 
We want to figure out the number of times 73166680 can be divided by 215.

Moving on to step 1:
The number 215 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
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

On to step 2:
The number 215 fits into 73 0 times, leaving a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 73, we get 73.
Take the next digit (1) from the dividend and append it to 73, then repeat: 731 / 215

Let's proceed to step 3:
215 can be fit into 731 3 times, resulting in a remainder of 86.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 645 from 731 to get 86.
Bring next digit (6) of the dividend behind the 86 and repeat the process: 866 / 215

Advancing to step 4:
If we divide 866 by 215, we get 4 and a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 34.0
Subtracting 860 from 866 leaves us with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 215

Advancing to step 5:
215 can be fit into 66 0 times, resulting in a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 340.0
Deduct 0 from 66 and we're left with 66.
Bring next digit (6) of the dividend behind the 66 and repeat the process: 666 / 215

Step 6:
If we divide 666 by 215, we get 3 and a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 3403.0
Subtract 645 from 666 to get 21.
Fetch the next digit (8) from the dividend, attach it to 21 and continue: 218 / 215

On to step 7:
The number 215 fits into 218 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 34031.0
The remainder is 3 after subtracting 215 from 218.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 215

Advancing to step 8:
The number 215 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 340310.0
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 9:
If we divide 300 by 215, we get 1 and a remainder of 85.
Record the quotient 1 as the next digit in the result. 
Result so far: 340310.1
If we subtract 215 from 300, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 10:
215 goes into 850 3 times with a remainder of 205.
Record the quotient 3 as the next digit in the result. 
Result so far: 340310.13
Subtract 645 from 850 to get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Step 11:
215 goes into 2050 9 times with a remainder of 115.
Put 9 as the next digit of the answer. 
Result so far: 340310.139
Subtracting 1935 from 2050 leaves us with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 12:
The number 215 fits into 1150 5 times, leaving a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 340310.1395
Subtract 1075 from 1150 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 13:
750 divided by 215 is 3 with a remainder of 105.
The next digit of our result is 3. 
Result so far: 340310.13953
Deduct 645 from 750 and we're left with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

On to step 14:
1050 divided by 215 is 4 with a remainder of 190.
The next digit of our result is 4. 
Result so far: 340310.139534
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 15:
When dividing 1900 by 215, we get 8 with a remainder of 180.
The number 8 becomes the next digit in our result. 
Result so far: 340310.1395348
Subtract 1720 from 1900 to 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.

Advancing to step 16:
215 can be fit into 1800 8 times, resulting in a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 340310.13953488
Subtract 1720 from 1800 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

After the division, we end up with 340310.13953488 and a remainder of 8e-08.
