We're dividing 23900456 by 408 
Let's see how many times 408 fits into 23900456.

Let's proceed to step 1:
If we divide 2 by 408, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 408

Moving on to step 2:
408 goes into 23 0 times with a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 23, we get 23.
Bring next digit (9) of the dividend behind the 23 and repeat the process: 239 / 408

Advancing to step 3:
239 divided by 408 is 0 with a remainder of 239.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 239 and we're left with 239.
Append the next digit (0) from the dividend to 239 and continue with: 2390 / 408

Advancing to step 4:
When dividing 2390 by 408, we get 5 with a remainder of 350.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 2040 from 2390 to get 350.
Fetch the next digit (0) from the dividend, attach it to 350 and continue: 3500 / 408

On to step 5:
The number 408 fits into 3500 8 times, leaving a remainder of 236.
Put 8 as the next digit of the answer. 
Result so far: 58.0
The remainder is 236 after subtracting 3264 from 3500.
Take the next digit (4) from the dividend and append it to 236, then repeat: 2364 / 408

Going ahead to step 6:
The number 408 fits into 2364 5 times, leaving a remainder of 324.
Put 5 as the next digit of the answer. 
Result so far: 585.0
The remainder is 324 after subtracting 2040 from 2364.
Include the next digit (5) from the dividend after 324, then repeat: 3245 / 408

Moving on to step 7:
408 goes into 3245 7 times with a remainder of 389.
Put 7 as the next digit of the answer. 
Result so far: 5857.0
Subtract 2856 from 3245 to get 389.
Fetch the next digit (6) from the dividend, attach it to 389 and continue: 3896 / 408

Going ahead to step 8:
The number 408 fits into 3896 9 times, leaving a remainder of 224.
Write down 9 as next digit of the result. 
Result so far: 58579.0
Deduct 3672 from 3896 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Moving on to step 9:
2240 divided by 408 is 5 with a remainder of 200.
Use 5 as the next digit of our solution. 
Result so far: 58579.5
Subtracting 2040 from 2240 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 10:
If we divide 2000 by 408, we get 4 and a remainder of 368.
Use 4 as the next digit of our solution. 
Result so far: 58579.54
Subtracting 1632 from 2000 leaves us with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Moving on to step 11:
When dividing 3680 by 408, we get 9 with a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 58579.549
Subtracting 3672 from 3680 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 12:
408 can be fit into 80 0 times, resulting in a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 58579.549
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 13:
When dividing 800 by 408, we get 1 with a remainder of 392.
Put 1 as the next digit of the answer. 
Result so far: 58579.54901
If we take 408 away from 800, we end up with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Going ahead to step 14:
408 goes into 3920 9 times with a remainder of 248.
Write down 9 as next digit of the result. 
Result so far: 58579.549019
The remainder is 248 after subtracting 3672 from 3920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Step 15:
The number 408 fits into 2480 6 times, leaving a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 58579.5490196
Subtracting 2448 from 2480 leaves us 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.

Let's proceed to step 16:
408 goes into 320 0 times with a remainder of 320.
Use 0 as the next digit of our solution. 
Result so far: 58579.5490196
Subtracting 0 from 320 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

The quotient of the division is 58579.5490196, and the remainder is 3.2e-07.
