We divide 93288009 by 399
We want to figure out the number of times 93288009 can be divided by 399.

On to step 1:
399 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 399

Going ahead to step 2:
When dividing 93 by 399, we get 0 with a remainder of 93.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 93 leaves us with 93.
Include the next digit (2) from the dividend after 93, then repeat: 932 / 399

Going ahead to step 3:
932 divided by 399 is 2 with a remainder of 134.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 798 from 932 and we're left with 134.
Append the next digit (8) from the dividend to 134 and continue with: 1348 / 399

Going ahead to step 4:
When dividing 1348 by 399, we get 3 with a remainder of 151.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtracting 1197 from 1348 leaves us with 151.
Bring next digit (8) of the dividend behind the 151 and repeat the process: 1518 / 399

Let's proceed to step 5:
399 can be fit into 1518 3 times, resulting in a remainder of 321.
Put 3 as the next digit of the answer. 
Result so far: 233.0
If we take 1197 away from 1518, we end up with 321.
Include the next digit (0) from the dividend after 321, then repeat: 3210 / 399

Moving on to step 6:
The number 399 fits into 3210 8 times, leaving a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 2338.0
The remainder is 18 after subtracting 3192 from 3210.
Take the next digit (0) from the dividend and append it to 18, then repeat: 180 / 399

On to step 7:
When dividing 180 by 399, we get 0 with a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 23380.0
The remainder is 180 after subtracting 0 from 180.
Append the next digit (9) from the dividend to 180 and continue with: 1809 / 399

Step 8:
399 can be fit into 1809 4 times, resulting in a remainder of 213.
Use 4 as the next digit of our solution. 
Result so far: 233804.0
Deduct 1596 from 1809 and we're left with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

On to step 9:
399 goes into 2130 5 times with a remainder of 135.
Record the quotient 5 as the next digit in the result. 
Result so far: 233804.5
Subtracting 1995 from 2130 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

On to step 10:
If we divide 1350 by 399, we get 3 and a remainder of 153.
The next digit of our result is 3. 
Result so far: 233804.53
If we take 1197 away from 1350, we end up with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

On to step 11:
When dividing 1530 by 399, we get 3 with a remainder of 333.
The number 3 becomes the next digit in our result. 
Result so far: 233804.533
Subtract 1197 from 1530 to get 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

In conclusion, the division gives 233804.533 with a balance of 0.0333.
