64484207 ÷ 215 
We're looking to find how many times 215 goes into 64484207.

Advancing to step 1:
The number 215 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 215

Moving on to step 2:
215 can be fit into 64 0 times, resulting in a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Fetch the next digit (4) from the dividend, attach it to 64 and continue: 644 / 215

Let's proceed to step 3:
If we divide 644 by 215, we get 2 and a remainder of 214.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 430 away from 644, we end up with 214.
Bring next digit (8) of the dividend behind the 214 and repeat the process: 2148 / 215

Going ahead to step 4:
215 can be fit into 2148 9 times, resulting in a remainder of 213.
Use 9 as the next digit of our solution. 
Result so far: 29.0
The remainder is 213 after subtracting 1935 from 2148.
Fetch the next digit (4) from the dividend, attach it to 213 and continue: 2134 / 215

Let's proceed to step 5:
215 can be fit into 2134 9 times, resulting in a remainder of 199.
The number 9 becomes the next digit in our result. 
Result so far: 299.0
Subtracting 1935 from 2134 leaves us with 199.
Take the next digit (2) from the dividend and append it to 199, then repeat: 1992 / 215

Let's proceed to step 6:
1992 divided by 215 is 9 with a remainder of 57.
Use 9 as the next digit of our solution. 
Result so far: 2999.0
Deduct 1935 from 1992 and we're left with 57.
Take the next digit (0) from the dividend and append it to 57, then repeat: 570 / 215

Let's proceed to step 7:
The number 215 fits into 570 2 times, leaving a remainder of 140.
Record the quotient 2 as the next digit in the result. 
Result so far: 29992.0
If we subtract 430 from 570, we get 140.
Fetch the next digit (7) from the dividend, attach it to 140 and continue: 1407 / 215

Moving on to step 8:
When dividing 1407 by 215, we get 6 with a remainder of 117.
Put 6 as the next digit of the answer. 
Result so far: 299926.0
If we subtract 1290 from 1407, we get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Step 9:
When dividing 1170 by 215, we get 5 with a remainder of 95.
The number 5 becomes the next digit in our result. 
Result so far: 299926.5
The remainder is 95 after subtracting 1075 from 1170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Step 10:
If we divide 950 by 215, we get 4 and a remainder of 90.
The next digit of our result is 4. 
Result so far: 299926.54
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.

Moving on to step 11:
If we divide 900 by 215, we get 4 and a remainder of 40.
The next digit of our result is 4. 
Result so far: 299926.544
Deduct 860 from 900 and we're left 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.

Our division results in 299926.544 with a remaining 0.004.
