We divide 64830770 by 15
We want to divide 64830770 by 15.

Advancing to step 1:
6 divided by 15 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 15

Moving on to step 2:
15 can be fit into 64 4 times, resulting in a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 60 away from 64, we end up with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 15

Let's proceed to step 3:
15 goes into 48 3 times with a remainder of 3.
The next digit of our result is 3. 
Result so far: 43.0
Subtract 45 from 48 to get 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 15

Step 4:
If we divide 33 by 15, we get 2 and a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 432.0
If we subtract 30 from 33, we get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 15

Step 5:
The number 15 fits into 30 2 times, leaving a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 4322.0
Deduct 30 from 30 and we're left with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 15

Advancing to step 6:
When dividing 7 by 15, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 43220.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 15

Advancing to step 7:
When dividing 77 by 15, we get 5 with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 432205.0
The remainder is 2 after subtracting 75 from 77.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 15

Step 8:
If we divide 20 by 15, we get 1 and a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 4322051.0
If we take 15 away from 20, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
15 goes into 50 3 times with a remainder of 5.
The next digit of our result is 3. 
Result so far: 4322051.3
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 10:
The number 15 fits into 50 3 times, leaving a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 4322051.33
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 4322051.33 with a remainder of 0.005.
