Let's divide 78393441 by 555
We want to divide 78393441 by 555.

On to step 1:
The number 555 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 555

Moving on to step 2:
555 goes into 78 0 times with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Take the next digit (3) from the dividend and append it to 78, then repeat: 783 / 555

Going ahead to step 3:
783 divided by 555 is 1 with a remainder of 228.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 555 from 783 to get 228.
Append the next digit (9) from the dividend to 228 and continue with: 2289 / 555

Advancing to step 4:
555 can be fit into 2289 4 times, resulting in a remainder of 69.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
The remainder is 69 after subtracting 2220 from 2289.
Include the next digit (3) from the dividend after 69, then repeat: 693 / 555

On to step 5:
693 divided by 555 is 1 with a remainder of 138.
Put 1 as the next digit of the answer. 
Result so far: 141.0
If we subtract 555 from 693, we get 138.
Append the next digit (4) from the dividend to 138 and continue with: 1384 / 555

Step 6:
When dividing 1384 by 555, we get 2 with a remainder of 274.
Record the quotient 2 as the next digit in the result. 
Result so far: 1412.0
If we take 1110 away from 1384, we end up with 274.
Bring next digit (4) of the dividend behind the 274 and repeat the process: 2744 / 555

Step 7:
When dividing 2744 by 555, we get 4 with a remainder of 524.
The next digit of our result is 4. 
Result so far: 14124.0
Subtracting 2220 from 2744 leaves us with 524.
Fetch the next digit (1) from the dividend, attach it to 524 and continue: 5241 / 555

Going ahead to step 8:
555 can be fit into 5241 9 times, resulting in a remainder of 246.
Write down 9 as next digit of the result. 
Result so far: 141249.0
Subtracting 4995 from 5241 leaves us with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Let's proceed to step 9:
When dividing 2460 by 555, we get 4 with a remainder of 240.
Use 4 as the next digit of our solution. 
Result so far: 141249.4
Subtracting 2220 from 2460 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 10:
555 goes into 2400 4 times with a remainder of 180.
Record the quotient 4 as the next digit in the result. 
Result so far: 141249.44
The remainder is 180 after subtracting 2220 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

The quotient of the division is 141249.44, and the remainder is 0.18.
