8268240 divided by 393 
Let's see how many times 393 fits into 8268240.

Going ahead to step 1:
8 divided by 393 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 393

Going ahead to step 2:
393 can be fit into 82 0 times, resulting in a remainder of 82.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 82 and we're left with 82.
Append the next digit (6) from the dividend to 82 and continue with: 826 / 393

Advancing to step 3:
When dividing 826 by 393, we get 2 with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 786 from 826 and we're left with 40.
Bring next digit (8) of the dividend behind the 40 and repeat the process: 408 / 393

Advancing to step 4:
If we divide 408 by 393, we get 1 and a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
The remainder is 15 after subtracting 393 from 408.
Bring next digit (2) of the dividend behind the 15 and repeat the process: 152 / 393

Let's proceed to step 5:
When dividing 152 by 393, we get 0 with a remainder of 152.
The number 0 becomes the next digit in our result. 
Result so far: 210.0
If we take 0 away from 152, we end up with 152.
Grab the next digit (4) from the dividend, add it to 152, then carry on: 1524 / 393

Going ahead to step 6:
The number 393 fits into 1524 3 times, leaving a remainder of 345.
Use 3 as the next digit of our solution. 
Result so far: 2103.0
Subtract 1179 from 1524 to get 345.
Append the next digit (0) from the dividend to 345 and continue with: 3450 / 393

Moving on to step 7:
When dividing 3450 by 393, we get 8 with a remainder of 306.
Record the quotient 8 as the next digit in the result. 
Result so far: 21038.0
If we take 3144 away from 3450, we end up with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Going ahead to step 8:
The number 393 fits into 3060 7 times, leaving a remainder of 309.
Put 7 as the next digit of the answer. 
Result so far: 21038.7
Deduct 2751 from 3060 and we're left with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Advancing to step 9:
The number 393 fits into 3090 7 times, leaving a remainder of 339.
Use 7 as the next digit of our solution. 
Result so far: 21038.77
The remainder is 339 after subtracting 2751 from 3090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

After the division, we end up with 21038.77 and a remainder of 0.339.
