78055504 divided by 64 
Our goal is to divide 78055504 by 64.

Moving on to step 1:
If we divide 7 by 64, we get 0 and 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.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 64

Moving on to step 2:
64 can be fit into 78 1 times, resulting in a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 64 from 78 and we're left with 14.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 64

On to step 3:
If we divide 140 by 64, we get 2 and a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 12 after subtracting 128 from 140.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 64

Moving on to step 4:
125 divided by 64 is 1 with a remainder of 61.
The number 1 becomes the next digit in our result. 
Result so far: 121.0
If we take 64 away from 125, we end up with 61.
Take the next digit (5) from the dividend and append it to 61, then repeat: 615 / 64

Advancing to step 5:
64 goes into 615 9 times with a remainder of 39.
The next digit of our result is 9. 
Result so far: 1219.0
Deduct 576 from 615 and we're left with 39.
Bring next digit (5) of the dividend behind the 39 and repeat the process: 395 / 64

Moving on to step 6:
395 divided by 64 is 6 with a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 12196.0
If we take 384 away from 395, we end up with 11.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 64

Going ahead to step 7:
The number 64 fits into 110 1 times, leaving a remainder of 46.
Use 1 as the next digit of our solution. 
Result so far: 121961.0
Subtract 64 from 110 to get 46.
Grab the next digit (4) from the dividend, add it to 46, then carry on: 464 / 64

Let's proceed to step 8:
When dividing 464 by 64, we get 7 with a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 1219617.0
If we take 448 away from 464, 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.

Step 9:
160 divided by 64 is 2 with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 1219617.2
If we subtract 128 from 160, we 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 10:
When dividing 320 by 64, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 1219617.25
If we take 320 away from 320, we end up 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.

Advancing to step 11:
0 divided by 64 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1219617.25
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.

Advancing to step 12:
64 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1219617.25
If we subtract 0 from 0, we 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.

The final outcome is 1219617.25, with a leftover of 0.0.
