We're dividing 122393 by 64 
We're looking to find how many times 64 goes into 122393.

Advancing to step 1:
When dividing 1 by 64, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 64

On to step 2:
The number 64 fits into 12 0 times, leaving a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 64

Advancing to step 3:
When dividing 122 by 64, we get 1 with a remainder of 58.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 64 from 122 leaves us with 58.
Append the next digit (3) from the dividend to 58 and continue with: 583 / 64

Advancing to step 4:
The number 64 fits into 583 9 times, leaving a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtracting 576 from 583 leaves us with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 64

On to step 5:
64 goes into 79 1 times with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 191.0
The remainder is 15 after subtracting 64 from 79.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 64

Advancing to step 6:
64 goes into 153 2 times with a remainder of 25.
Use 2 as the next digit of our solution. 
Result so far: 1912.0
Subtracting 128 from 153 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 7:
64 can be fit into 250 3 times, resulting in a remainder of 58.
The next digit of our result is 3. 
Result so far: 1912.3
If we take 192 away from 250, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 8:
64 goes into 580 9 times with a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 1912.39
Subtract 576 from 580 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
64 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 1912.39
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
If we divide 400 by 64, we get 6 and a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 1912.3906
If we subtract 384 from 400, we get 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 11:
When dividing 160 by 64, we get 2 with a remainder of 32.
The next digit of our result is 2. 
Result so far: 1912.39062
If we take 128 away from 160, 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.

Advancing to step 12:
The number 64 fits into 320 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 1912.390625
Deduct 320 from 320 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.

Step 13:
64 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1912.390625
If we take 0 away from 0, 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.

Step 14:
64 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1912.390625
Subtract 0 from 0 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.

The final result is 1912.390625 with a remainder of 0.0.
