23640 divided by 58 
We want to figure out the number of times 23640 can be divided by 58.

Let's proceed to step 1:
2 divided by 58 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 58

Moving on to step 2:
If we divide 23 by 58, we get 0 and a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 23 leaves us with 23.
Grab the next digit (6) from the dividend, add it to 23, then carry on: 236 / 58

Step 3:
58 can be fit into 236 4 times, resulting in a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 232 from 236 leaves us with 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 58

Going ahead to step 4:
The number 58 fits into 44 0 times, leaving a remainder of 44.
The next digit of our result is 0. 
Result so far: 40.0
If we take 0 away from 44, we end up with 44.
Take the next digit (0) from the dividend and append it to 44, then repeat: 440 / 58

Moving on to step 5:
When dividing 440 by 58, we get 7 with a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 407.0
Subtracting 406 from 440 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 6:
58 can be fit into 340 5 times, resulting in a remainder of 50.
The next digit of our result is 5. 
Result so far: 407.5
If we take 290 away from 340, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 7:
58 goes into 500 8 times with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 407.58
If we subtract 464 from 500, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 8:
360 divided by 58 is 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 407.586
Deduct 348 from 360 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
120 divided by 58 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 407.5862
Subtract 116 from 120 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.

On to step 10:
58 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 407.5862
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
The number 58 fits into 400 6 times, leaving a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 407.586206
If we take 348 away from 400, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 12:
The number 58 fits into 520 8 times, leaving a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 407.5862068
If we subtract 464 from 520, we 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.

On to step 13:
The number 58 fits into 560 9 times, leaving a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 407.58620689
If we subtract 522 from 560, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Our division results in 407.58620689 with a remaining 3.8e-08.
