97781820 divided by 64 
We want to figure out the number of times 97781820 can be divided by 64.

Advancing to step 1:
When dividing 9 by 64, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 64

Step 2:
64 goes into 97 1 times with a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 64 from 97 to get 33.
Append the next digit (7) from the dividend to 33 and continue with: 337 / 64

Moving on to step 3:
If we divide 337 by 64, we get 5 and a remainder of 17.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 320 away from 337, we end up with 17.
Include the next digit (8) from the dividend after 17, then repeat: 178 / 64

Let's proceed to step 4:
The number 64 fits into 178 2 times, leaving a remainder of 50.
The next digit of our result is 2. 
Result so far: 152.0
Deduct 128 from 178 and we're left with 50.
Include the next digit (1) from the dividend after 50, then repeat: 501 / 64

Step 5:
When dividing 501 by 64, we get 7 with a remainder of 53.
The number 7 becomes the next digit in our result. 
Result so far: 1527.0
The remainder is 53 after subtracting 448 from 501.
Include the next digit (8) from the dividend after 53, then repeat: 538 / 64

Moving on to step 6:
64 goes into 538 8 times with a remainder of 26.
Write down 8 as next digit of the result. 
Result so far: 15278.0
If we subtract 512 from 538, we get 26.
Include the next digit (2) from the dividend after 26, then repeat: 262 / 64

Step 7:
If we divide 262 by 64, we get 4 and a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 152784.0
If we take 256 away from 262, we end up with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 64

Advancing to step 8:
The number 64 fits into 60 0 times, leaving a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 1527840.0
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 9:
64 can be fit into 600 9 times, resulting in a remainder of 24.
Record the quotient 9 as the next digit in the result. 
Result so far: 1527840.9
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 10:
64 goes into 240 3 times with a remainder of 48.
The number 3 becomes the next digit in our result. 
Result so far: 1527840.93
The remainder is 48 after subtracting 192 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 11:
64 can be fit into 480 7 times, resulting in a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 1527840.937
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.

On to step 12:
320 divided by 64 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 1527840.9375
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.

Advancing to step 13:
64 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1527840.9375
The remainder is 0 after subtracting 0 from 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 14:
0 divided by 64 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1527840.9375
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 1527840.9375 with a balance of 0.0.
