We divide 79964615 by 215
We want to figure out the number of times 79964615 can be divided by 215.

On to step 1:
215 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 215

Moving on to step 2:
215 goes into 79 0 times with a remainder of 79.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 79, we get 79.
Include the next digit (9) from the dividend after 79, then repeat: 799 / 215

On to step 3:
The number 215 fits into 799 3 times, leaving a remainder of 154.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 645 from 799, we get 154.
Include the next digit (6) from the dividend after 154, then repeat: 1546 / 215

Let's proceed to step 4:
215 can be fit into 1546 7 times, resulting in a remainder of 41.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
If we take 1505 away from 1546, we end up with 41.
Grab the next digit (4) from the dividend, add it to 41, then carry on: 414 / 215

Advancing to step 5:
If we divide 414 by 215, we get 1 and a remainder of 199.
Write down 1 as next digit of the result. 
Result so far: 371.0
Deduct 215 from 414 and we're left with 199.
Append the next digit (6) from the dividend to 199 and continue with: 1996 / 215

Moving on to step 6:
215 can be fit into 1996 9 times, resulting in a remainder of 61.
The next digit of our result is 9. 
Result so far: 3719.0
Deduct 1935 from 1996 and we're left with 61.
Bring next digit (1) of the dividend behind the 61 and repeat the process: 611 / 215

On to step 7:
611 divided by 215 is 2 with a remainder of 181.
Record the quotient 2 as the next digit in the result. 
Result so far: 37192.0
Subtract 430 from 611 to get 181.
Include the next digit (5) from the dividend after 181, then repeat: 1815 / 215

Advancing to step 8:
If we divide 1815 by 215, we get 8 and a remainder of 95.
Write down 8 as next digit of the result. 
Result so far: 371928.0
If we take 1720 away from 1815, we end up with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Step 9:
950 divided by 215 is 4 with a remainder of 90.
The number 4 becomes the next digit in our result. 
Result so far: 371928.4
Subtract 860 from 950 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 10:
When dividing 900 by 215, we get 4 with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 371928.44
If we take 860 away from 900, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 371928.44 and a remainder of 0.04.
