51318798 divided by 64 
Let's see how many times 64 fits into 51318798.

Let's proceed to step 1:
The number 64 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 64

Step 2:
If we divide 51 by 64, we get 0 and a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Include the next digit (3) from the dividend after 51, then repeat: 513 / 64

Moving on to step 3:
64 can be fit into 513 8 times, resulting in a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 512 from 513, we get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 64

Let's proceed to step 4:
64 can be fit into 11 0 times, resulting in a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
If we subtract 0 from 11, we get 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 64

Advancing to step 5:
The number 64 fits into 118 1 times, leaving a remainder of 54.
The next digit of our result is 1. 
Result so far: 801.0
Subtract 64 from 118 to get 54.
Grab the next digit (7) from the dividend, add it to 54, then carry on: 547 / 64

Step 6:
64 can be fit into 547 8 times, resulting in a remainder of 35.
The number 8 becomes the next digit in our result. 
Result so far: 8018.0
If we subtract 512 from 547, we get 35.
Fetch the next digit (9) from the dividend, attach it to 35 and continue: 359 / 64

Moving on to step 7:
359 divided by 64 is 5 with a remainder of 39.
The next digit of our result is 5. 
Result so far: 80185.0
If we take 320 away from 359, we end up with 39.
Take the next digit (8) from the dividend and append it to 39, then repeat: 398 / 64

Going ahead to step 8:
398 divided by 64 is 6 with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 801856.0
Subtracting 384 from 398 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 9:
64 goes into 140 2 times with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 801856.2
Subtract 128 from 140 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
64 can be fit into 120 1 times, resulting in a remainder of 56.
The number 1 becomes the next digit in our result. 
Result so far: 801856.21
Subtract 64 from 120 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 11:
64 can be fit into 560 8 times, resulting in a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 801856.218
The remainder is 48 after subtracting 512 from 560.
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 12:
64 can be fit into 480 7 times, resulting in a remainder of 32.
Record the quotient 7 as the next digit in the result. 
Result so far: 801856.2187
If we subtract 448 from 480, 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.

Moving on to step 13:
320 divided by 64 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 801856.21875
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.

Let's proceed to step 14:
64 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 801856.21875
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.

Let's proceed to step 15:
0 divided by 64 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 801856.21875
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.

In conclusion, the division gives 801856.21875 with a balance of 0.0.
