We divide 78817853 by 64
We want to divide 78817853 by 64.

On to step 1:
7 divided by 64 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 64

Going ahead to step 2:
64 goes into 78 1 times with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 64 from 78 and we're left with 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 64

Let's proceed to step 3:
The number 64 fits into 148 2 times, leaving a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 128 from 148 to get 20.
Include the next digit (1) from the dividend after 20, then repeat: 201 / 64

Advancing to step 4:
If we divide 201 by 64, we get 3 and a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 123.0
If we subtract 192 from 201, we get 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 64

Let's proceed to step 5:
64 can be fit into 97 1 times, resulting in a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 1231.0
Subtracting 64 from 97 leaves us with 33.
Bring next digit (8) of the dividend behind the 33 and repeat the process: 338 / 64

On to step 6:
64 can be fit into 338 5 times, resulting in a remainder of 18.
Write down 5 as next digit of the result. 
Result so far: 12315.0
If we subtract 320 from 338, we get 18.
Bring next digit (5) of the dividend behind the 18 and repeat the process: 185 / 64

Let's proceed to step 7:
64 goes into 185 2 times with a remainder of 57.
Put 2 as the next digit of the answer. 
Result so far: 123152.0
If we subtract 128 from 185, we get 57.
Grab the next digit (3) from the dividend, add it to 57, then carry on: 573 / 64

On to step 8:
The number 64 fits into 573 8 times, leaving a remainder of 61.
Record the quotient 8 as the next digit in the result. 
Result so far: 1231528.0
Subtracting 512 from 573 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 9:
When dividing 610 by 64, we get 9 with a remainder of 34.
Write down 9 as next digit of the result. 
Result so far: 1231528.9
The remainder is 34 after subtracting 576 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 10:
If we divide 340 by 64, we get 5 and a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 1231528.95
If we subtract 320 from 340, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 11:
If we divide 200 by 64, we get 3 and a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 1231528.953
If we take 192 away from 200, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 12:
When dividing 80 by 64, we get 1 with a remainder of 16.
The next digit of our result is 1. 
Result so far: 1231528.9531
If we take 64 away from 80, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
When dividing 160 by 64, we get 2 with a remainder of 32.
The next digit of our result is 2. 
Result so far: 1231528.95312
Subtract 128 from 160 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 14:
320 divided by 64 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 1231528.953125
Deduct 320 from 320 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 15:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1231528.953125
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 16:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1231528.953125
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 1231528.953125 with a balance of 0.0.
