64130992 ÷ 816 
Let's see how many times 816 fits into 64130992.

Moving on to step 1:
If we divide 6 by 816, we get 0 and 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.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 816

On to step 2:
816 can be fit into 64 0 times, resulting in a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Include the next digit (1) from the dividend after 64, then repeat: 641 / 816

Going ahead to step 3:
816 goes into 641 0 times with a remainder of 641.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 641 leaves us with 641.
Append the next digit (3) from the dividend to 641 and continue with: 6413 / 816

Going ahead to step 4:
6413 divided by 816 is 7 with a remainder of 701.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 5712 from 6413 to get 701.
Fetch the next digit (0) from the dividend, attach it to 701 and continue: 7010 / 816

Moving on to step 5:
816 goes into 7010 8 times with a remainder of 482.
The next digit of our result is 8. 
Result so far: 78.0
Subtract 6528 from 7010 to get 482.
Take the next digit (9) from the dividend and append it to 482, then repeat: 4829 / 816

On to step 6:
816 goes into 4829 5 times with a remainder of 749.
Use 5 as the next digit of our solution. 
Result so far: 785.0
Subtract 4080 from 4829 to get 749.
Include the next digit (9) from the dividend after 749, then repeat: 7499 / 816

Moving on to step 7:
The number 816 fits into 7499 9 times, leaving a remainder of 155.
The next digit of our result is 9. 
Result so far: 7859.0
Deduct 7344 from 7499 and we're left with 155.
Grab the next digit (2) from the dividend, add it to 155, then carry on: 1552 / 816

Moving on to step 8:
1552 divided by 816 is 1 with a remainder of 736.
Put 1 as the next digit of the answer. 
Result so far: 78591.0
The remainder is 736 after subtracting 816 from 1552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Let's proceed to step 9:
7360 divided by 816 is 9 with a remainder of 16.
Use 9 as the next digit of our solution. 
Result so far: 78591.9
Subtract 7344 from 7360 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
If we divide 160 by 816, we get 0 and a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 78591.9
Subtract 0 from 160 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 11:
If we divide 1600 by 816, we get 1 and a remainder of 784.
Use 1 as the next digit of our solution. 
Result so far: 78591.901
Subtract 816 from 1600 to get 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

On to step 12:
When dividing 7840 by 816, we get 9 with a remainder of 496.
Use 9 as the next digit of our solution. 
Result so far: 78591.9019
If we take 7344 away from 7840, we end up with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Moving on to step 13:
816 can be fit into 4960 6 times, resulting in a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 78591.90196
The remainder is 64 after subtracting 4896 from 4960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 14:
816 goes into 640 0 times with a remainder of 640.
Use 0 as the next digit of our solution. 
Result so far: 78591.90196
Subtracting 0 from 640 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 15:
816 goes into 6400 7 times with a remainder of 688.
Use 7 as the next digit of our solution. 
Result so far: 78591.9019607
Subtract 5712 from 6400 to get 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Advancing to step 16:
If we divide 6880 by 816, we get 8 and a remainder of 352.
Write down 8 as next digit of the result. 
Result so far: 78591.90196078
If we take 6528 away from 6880, we end up with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

In conclusion, the division gives 78591.90196078 with a balance of 3.52e-07.
