Let's divide 78756631 by 64
We're looking to find how many times 64 goes into 78756631.

Step 1:
64 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 64

On to step 2:
If we divide 78 by 64, we get 1 and a remainder of 14.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 14 after subtracting 64 from 78.
Bring next digit (7) of the dividend behind the 14 and repeat the process: 147 / 64

Going ahead to step 3:
64 goes into 147 2 times with a remainder of 19.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 19 after subtracting 128 from 147.
Include the next digit (5) from the dividend after 19, then repeat: 195 / 64

Advancing to step 4:
When dividing 195 by 64, we get 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 123.0
Deduct 192 from 195 and we're left with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 64

Moving on to step 5:
64 can be fit into 36 0 times, resulting in a remainder of 36.
Use 0 as the next digit of our solution. 
Result so far: 1230.0
The remainder is 36 after subtracting 0 from 36.
Fetch the next digit (6) from the dividend, attach it to 36 and continue: 366 / 64

Going ahead to step 6:
64 goes into 366 5 times with a remainder of 46.
Put 5 as the next digit of the answer. 
Result so far: 12305.0
Subtract 320 from 366 to get 46.
Bring next digit (3) of the dividend behind the 46 and repeat the process: 463 / 64

Advancing to step 7:
If we divide 463 by 64, we get 7 and a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 123057.0
The remainder is 15 after subtracting 448 from 463.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 64

On to step 8:
When dividing 151 by 64, we get 2 with a remainder of 23.
Use 2 as the next digit of our solution. 
Result so far: 1230572.0
Subtract 128 from 151 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 9:
64 goes into 230 3 times with a remainder of 38.
Record the quotient 3 as the next digit in the result. 
Result so far: 1230572.3
Subtracting 192 from 230 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 10:
When dividing 380 by 64, we get 5 with a remainder of 60.
The next digit of our result is 5. 
Result so far: 1230572.35
Subtracting 320 from 380 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 11:
When dividing 600 by 64, we get 9 with a remainder of 24.
Write down 9 as next digit of the result. 
Result so far: 1230572.359
The remainder is 24 after subtracting 576 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 12:
240 divided by 64 is 3 with a remainder of 48.
Put 3 as the next digit of the answer. 
Result so far: 1230572.3593
If we take 192 away from 240, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 13:
480 divided by 64 is 7 with a remainder of 32.
Record the quotient 7 as the next digit in the result. 
Result so far: 1230572.35937
If we take 448 away from 480, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 14:
If we divide 320 by 64, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 1230572.359375
Subtract 320 from 320 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.

Step 15:
64 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1230572.359375
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.

On to step 16:
64 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1230572.359375
Subtracting 0 from 0 leaves us 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.

In conclusion, the division gives 1230572.359375 with a balance of 0.0.
