We're dividing 123959 by 64 
Our goal is to divide 123959 by 64.

Advancing to step 1:
64 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 64

On to step 2:
64 can be fit into 12 0 times, resulting in a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 64

Moving on to step 3:
When dividing 123 by 64, we get 1 with a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 64 from 123 leaves us with 59.
Take the next digit (9) from the dividend and append it to 59, then repeat: 599 / 64

Advancing to step 4:
64 can be fit into 599 9 times, resulting in a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Deduct 576 from 599 and we're left with 23.
Append the next digit (5) from the dividend to 23 and continue with: 235 / 64

Advancing to step 5:
If we divide 235 by 64, we get 3 and a remainder of 43.
The next digit of our result is 3. 
Result so far: 193.0
Subtracting 192 from 235 leaves us with 43.
Include the next digit (9) from the dividend after 43, then repeat: 439 / 64

Moving on to step 6:
When dividing 439 by 64, we get 6 with a remainder of 55.
Record the quotient 6 as the next digit in the result. 
Result so far: 1936.0
Subtracting 384 from 439 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 7:
When dividing 550 by 64, we get 8 with a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 1936.8
The remainder is 38 after subtracting 512 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 8:
When dividing 380 by 64, we get 5 with a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 1936.85
If we subtract 320 from 380, we 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.

Step 9:
64 can be fit into 600 9 times, resulting in a remainder of 24.
The number 9 becomes the next digit in our result. 
Result so far: 1936.859
If we subtract 576 from 600, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
When dividing 240 by 64, we get 3 with a remainder of 48.
Write down 3 as next digit of the result. 
Result so far: 1936.8593
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.

Advancing to step 11:
The number 64 fits into 480 7 times, leaving a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 1936.85937
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.

Step 12:
64 can be fit into 320 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 1936.859375
Subtracting 320 from 320 leaves us 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.

Going ahead to step 13:
64 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1936.859375
Subtracting 0 from 0 leaves us 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.

On to step 14:
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: 1936.859375
Subtracting 0 from 0 leaves us 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 1936.859375 with a balance of 0.0.
