We're dividing 23281221 by 408 
We're looking to find how many times 408 goes into 23281221.

Step 1:
408 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 408

Moving on to step 2:
408 can be fit into 23 0 times, resulting in a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Take the next digit (2) from the dividend and append it to 23, then repeat: 232 / 408

Moving on to step 3:
232 divided by 408 is 0 with a remainder of 232.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 232, we end up with 232.
Grab the next digit (8) from the dividend, add it to 232, then carry on: 2328 / 408

On to step 4:
408 can be fit into 2328 5 times, resulting in a remainder of 288.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 2040 away from 2328, we end up with 288.
Bring next digit (1) of the dividend behind the 288 and repeat the process: 2881 / 408

Moving on to step 5:
When dividing 2881 by 408, we get 7 with a remainder of 25.
Use 7 as the next digit of our solution. 
Result so far: 57.0
Deduct 2856 from 2881 and we're left with 25.
Take the next digit (2) from the dividend and append it to 25, then repeat: 252 / 408

Let's proceed to step 6:
The number 408 fits into 252 0 times, leaving a remainder of 252.
Put 0 as the next digit of the answer. 
Result so far: 570.0
If we subtract 0 from 252, we get 252.
Include the next digit (2) from the dividend after 252, then repeat: 2522 / 408

Going ahead to step 7:
408 can be fit into 2522 6 times, resulting in a remainder of 74.
Record the quotient 6 as the next digit in the result. 
Result so far: 5706.0
Subtracting 2448 from 2522 leaves us with 74.
Include the next digit (1) from the dividend after 74, then repeat: 741 / 408

Going ahead to step 8:
408 goes into 741 1 times with a remainder of 333.
Write down 1 as next digit of the result. 
Result so far: 57061.0
Subtracting 408 from 741 leaves us with 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Advancing to step 9:
3330 divided by 408 is 8 with a remainder of 66.
The next digit of our result is 8. 
Result so far: 57061.8
If we subtract 3264 from 3330, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 10:
660 divided by 408 is 1 with a remainder of 252.
Use 1 as the next digit of our solution. 
Result so far: 57061.81
Deduct 408 from 660 and we're left with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Going ahead to step 11:
If we divide 2520 by 408, we get 6 and a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 57061.816
Subtract 2448 from 2520 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 12:
720 divided by 408 is 1 with a remainder of 312.
Record the quotient 1 as the next digit in the result. 
Result so far: 57061.8161
Subtracting 408 from 720 leaves us with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Step 13:
408 can be fit into 3120 7 times, resulting in a remainder of 264.
Record the quotient 7 as the next digit in the result. 
Result so far: 57061.81617
The remainder is 264 after subtracting 2856 from 3120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Step 14:
The number 408 fits into 2640 6 times, leaving a remainder of 192.
Write down 6 as next digit of the result. 
Result so far: 57061.816176
If we subtract 2448 from 2640, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 15:
When dividing 1920 by 408, we get 4 with a remainder of 288.
Use 4 as the next digit of our solution. 
Result so far: 57061.8161764
Subtract 1632 from 1920 to get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Advancing to step 16:
When dividing 2880 by 408, we get 7 with a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 57061.81617647
The remainder is 24 after subtracting 2856 from 2880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 57061.81617647 with a remaining 2.4e-08.
