We're dividing 23235432 by 591 
We want to divide 23235432 by 591.

Step 1:
If we divide 2 by 591, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 591

On to step 2:
591 can be fit into 23 0 times, resulting in a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 23 after subtracting 0 from 23.
Include the next digit (2) from the dividend after 23, then repeat: 232 / 591

Moving on to step 3:
When dividing 232 by 591, we get 0 with a remainder of 232.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 232, we get 232.
Include the next digit (3) from the dividend after 232, then repeat: 2323 / 591

Step 4:
When dividing 2323 by 591, we get 3 with a remainder of 550.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 1773 from 2323 leaves us with 550.
Bring next digit (5) of the dividend behind the 550 and repeat the process: 5505 / 591

Going ahead to step 5:
If we divide 5505 by 591, we get 9 and a remainder of 186.
Use 9 as the next digit of our solution. 
Result so far: 39.0
Deduct 5319 from 5505 and we're left with 186.
Fetch the next digit (4) from the dividend, attach it to 186 and continue: 1864 / 591

Advancing to step 6:
The number 591 fits into 1864 3 times, leaving a remainder of 91.
Record the quotient 3 as the next digit in the result. 
Result so far: 393.0
Subtracting 1773 from 1864 leaves us with 91.
Take the next digit (3) from the dividend and append it to 91, then repeat: 913 / 591

Moving on to step 7:
If we divide 913 by 591, we get 1 and a remainder of 322.
Write down 1 as next digit of the result. 
Result so far: 3931.0
Subtracting 591 from 913 leaves us with 322.
Append the next digit (2) from the dividend to 322 and continue with: 3222 / 591

Step 8:
591 can be fit into 3222 5 times, resulting in a remainder of 267.
The number 5 becomes the next digit in our result. 
Result so far: 39315.0
Deduct 2955 from 3222 and we're left with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Advancing to step 9:
591 can be fit into 2670 4 times, resulting in a remainder of 306.
Write down 4 as next digit of the result. 
Result so far: 39315.4
Subtract 2364 from 2670 to get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Let's proceed to step 10:
591 goes into 3060 5 times with a remainder of 105.
Record the quotient 5 as the next digit in the result. 
Result so far: 39315.45
The remainder is 105 after subtracting 2955 from 3060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Advancing to step 11:
591 can be fit into 1050 1 times, resulting in a remainder of 459.
Use 1 as the next digit of our solution. 
Result so far: 39315.451
Subtract 591 from 1050 to get 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

Let's proceed to step 12:
591 can be fit into 4590 7 times, resulting in a remainder of 453.
Put 7 as the next digit of the answer. 
Result so far: 39315.4517
The remainder is 453 after subtracting 4137 from 4590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

Going ahead to step 13:
591 can be fit into 4530 7 times, resulting in a remainder of 393.
The next digit of our result is 7. 
Result so far: 39315.45177
If we take 4137 away from 4530, we end up with 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

After the division, we end up with 39315.45177 and a remainder of 0.000393.
