79553912 ÷ 393 
We're looking to find how many times 393 goes into 79553912.

Advancing to step 1:
The number 393 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 393

Step 2:
79 divided by 393 is 0 with a remainder of 79.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 79 and we're left with 79.
Grab the next digit (5) from the dividend, add it to 79, then carry on: 795 / 393

Step 3:
393 goes into 795 2 times with a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 786 away from 795, we end up with 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 393

Advancing to step 4:
If we divide 95 by 393, we get 0 and a remainder of 95.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtracting 0 from 95 leaves us with 95.
Bring next digit (3) of the dividend behind the 95 and repeat the process: 953 / 393

Going ahead to step 5:
393 goes into 953 2 times with a remainder of 167.
The number 2 becomes the next digit in our result. 
Result so far: 202.0
Subtracting 786 from 953 leaves us with 167.
Take the next digit (9) from the dividend and append it to 167, then repeat: 1679 / 393

Step 6:
If we divide 1679 by 393, we get 4 and a remainder of 107.
Record the quotient 4 as the next digit in the result. 
Result so far: 2024.0
The remainder is 107 after subtracting 1572 from 1679.
Include the next digit (1) from the dividend after 107, then repeat: 1071 / 393

Going ahead to step 7:
The number 393 fits into 1071 2 times, leaving a remainder of 285.
The next digit of our result is 2. 
Result so far: 20242.0
If we take 786 away from 1071, we end up with 285.
Append the next digit (2) from the dividend to 285 and continue with: 2852 / 393

Advancing to step 8:
393 can be fit into 2852 7 times, resulting in a remainder of 101.
Put 7 as the next digit of the answer. 
Result so far: 202427.0
If we take 2751 away from 2852, we end up with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Going ahead to step 9:
The number 393 fits into 1010 2 times, leaving a remainder of 224.
Put 2 as the next digit of the answer. 
Result so far: 202427.2
Subtracting 786 from 1010 leaves us 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.

On to step 10:
The number 393 fits into 2240 5 times, leaving a remainder of 275.
The number 5 becomes the next digit in our result. 
Result so far: 202427.25
Deduct 1965 from 2240 and we're left with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

On to step 11:
The number 393 fits into 2750 6 times, leaving a remainder of 392.
The number 6 becomes the next digit in our result. 
Result so far: 202427.256
Subtract 2358 from 2750 to get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

On to step 12:
393 goes into 3920 9 times with a remainder of 383.
Use 9 as the next digit of our solution. 
Result so far: 202427.2569
Subtract 3537 from 3920 to get 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

Let's proceed to step 13:
393 goes into 3830 9 times with a remainder of 293.
The next digit of our result is 9. 
Result so far: 202427.25699
Subtract 3537 from 3830 to get 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

The final outcome is 202427.25699, with a leftover of 0.000293.
