Let's divide 64640064 by 54
Let's see how many times 54 fits into 64640064.

Advancing to step 1:
54 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 54

Advancing to step 2:
When dividing 64 by 54, we get 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 10 after subtracting 54 from 64.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 54

Going ahead to step 3:
54 can be fit into 106 1 times, resulting in a remainder of 52.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 54 away from 106, we end up with 52.
Take the next digit (4) from the dividend and append it to 52, then repeat: 524 / 54

Moving on to step 4:
If we divide 524 by 54, we get 9 and a remainder of 38.
Write down 9 as next digit of the result. 
Result so far: 119.0
If we subtract 486 from 524, we get 38.
Fetch the next digit (0) from the dividend, attach it to 38 and continue: 380 / 54

Moving on to step 5:
The number 54 fits into 380 7 times, leaving a remainder of 2.
The next digit of our result is 7. 
Result so far: 1197.0
If we take 378 away from 380, we end up with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 54

Step 6:
The number 54 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 11970.0
Deduct 0 from 20 and we're left with 20.
Grab the next digit (6) from the dividend, add it to 20, then carry on: 206 / 54

On to step 7:
When dividing 206 by 54, we get 3 with a remainder of 44.
Record the quotient 3 as the next digit in the result. 
Result so far: 119703.0
The remainder is 44 after subtracting 162 from 206.
Fetch the next digit (4) from the dividend, attach it to 44 and continue: 444 / 54

Going ahead to step 8:
54 can be fit into 444 8 times, resulting in a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 1197038.0
Deduct 432 from 444 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
120 divided by 54 is 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 1197038.2
The remainder is 12 after subtracting 108 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
54 can be fit into 120 2 times, resulting in a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 1197038.22
Subtracting 108 from 120 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 1197038.22 with a remainder of 0.012.
