64850046 divided by 815 
Let's see how many times 815 fits into 64850046.

On to step 1:
If we divide 6 by 815, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 815

Step 2:
64 divided by 815 is 0 with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Grab the next digit (8) from the dividend, add it to 64, then carry on: 648 / 815

Going ahead to step 3:
648 divided by 815 is 0 with a remainder of 648.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 648, we get 648.
Bring next digit (5) of the dividend behind the 648 and repeat the process: 6485 / 815

Moving on to step 4:
The number 815 fits into 6485 7 times, leaving a remainder of 780.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 5705 from 6485 to get 780.
Grab the next digit (0) from the dividend, add it to 780, then carry on: 7800 / 815

Advancing to step 5:
The number 815 fits into 7800 9 times, leaving a remainder of 465.
Write down 9 as next digit of the result. 
Result so far: 79.0
The remainder is 465 after subtracting 7335 from 7800.
Append the next digit (0) from the dividend to 465 and continue with: 4650 / 815

Step 6:
The number 815 fits into 4650 5 times, leaving a remainder of 575.
Put 5 as the next digit of the answer. 
Result so far: 795.0
Deduct 4075 from 4650 and we're left with 575.
Fetch the next digit (4) from the dividend, attach it to 575 and continue: 5754 / 815

Let's proceed to step 7:
If we divide 5754 by 815, we get 7 and a remainder of 49.
Record the quotient 7 as the next digit in the result. 
Result so far: 7957.0
If we take 5705 away from 5754, we end up with 49.
Grab the next digit (6) from the dividend, add it to 49, then carry on: 496 / 815

Advancing to step 8:
When dividing 496 by 815, we get 0 with a remainder of 496.
Put 0 as the next digit of the answer. 
Result so far: 79570.0
The remainder is 496 after subtracting 0 from 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Going ahead to step 9:
4960 divided by 815 is 6 with a remainder of 70.
The next digit of our result is 6. 
Result so far: 79570.6
The remainder is 70 after subtracting 4890 from 4960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 10:
If we divide 700 by 815, we get 0 and a remainder of 700.
Use 0 as the next digit of our solution. 
Result so far: 79570.6
If we subtract 0 from 700, we get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Advancing to step 11:
815 goes into 7000 8 times with a remainder of 480.
The next digit of our result is 8. 
Result so far: 79570.608
If we take 6520 away from 7000, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 12:
815 goes into 4800 5 times with a remainder of 725.
The number 5 becomes the next digit in our result. 
Result so far: 79570.6085
If we subtract 4075 from 4800, we get 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

Moving on to step 13:
When dividing 7250 by 815, we get 8 with a remainder of 730.
Put 8 as the next digit of the answer. 
Result so far: 79570.60858
If we take 6520 away from 7250, we end up with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Advancing to step 14:
The number 815 fits into 7300 8 times, leaving a remainder of 780.
Use 8 as the next digit of our solution. 
Result so far: 79570.608588
Deduct 6520 from 7300 and we're left with 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

The final result is 79570.608588 with a remainder of 7.8e-05.
