We look at the division of 77597517 by 393 
Let's see how many times 393 fits into 77597517.

Step 1:
If we divide 7 by 393, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 393

Going ahead to step 2:
77 divided by 393 is 0 with a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Include the next digit (5) from the dividend after 77, then repeat: 775 / 393

Moving on to step 3:
393 can be fit into 775 1 times, resulting in a remainder of 382.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 382 after subtracting 393 from 775.
Grab the next digit (9) from the dividend, add it to 382, then carry on: 3829 / 393

Advancing to step 4:
393 can be fit into 3829 9 times, resulting in a remainder of 292.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we take 3537 away from 3829, we end up with 292.
Take the next digit (7) from the dividend and append it to 292, then repeat: 2927 / 393

Moving on to step 5:
If we divide 2927 by 393, we get 7 and a remainder of 176.
Use 7 as the next digit of our solution. 
Result so far: 197.0
If we subtract 2751 from 2927, we get 176.
Bring next digit (5) of the dividend behind the 176 and repeat the process: 1765 / 393

On to step 6:
1765 divided by 393 is 4 with a remainder of 193.
Put 4 as the next digit of the answer. 
Result so far: 1974.0
The remainder is 193 after subtracting 1572 from 1765.
Append the next digit (1) from the dividend to 193 and continue with: 1931 / 393

Going ahead to step 7:
393 can be fit into 1931 4 times, resulting in a remainder of 359.
The number 4 becomes the next digit in our result. 
Result so far: 19744.0
If we subtract 1572 from 1931, we get 359.
Grab the next digit (7) from the dividend, add it to 359, then carry on: 3597 / 393

Advancing to step 8:
The number 393 fits into 3597 9 times, leaving a remainder of 60.
The number 9 becomes the next digit in our result. 
Result so far: 197449.0
The remainder is 60 after subtracting 3537 from 3597.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 9:
If we divide 600 by 393, we get 1 and a remainder of 207.
Record the quotient 1 as the next digit in the result. 
Result so far: 197449.1
Subtract 393 from 600 to get 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Moving on to step 10:
393 can be fit into 2070 5 times, resulting in a remainder of 105.
Write down 5 as next digit of the result. 
Result so far: 197449.15
Subtract 1965 from 2070 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Going ahead to step 11:
The number 393 fits into 1050 2 times, leaving a remainder of 264.
Record the quotient 2 as the next digit in the result. 
Result so far: 197449.152
Subtract 786 from 1050 to get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Going ahead to step 12:
393 goes into 2640 6 times with a remainder of 282.
Put 6 as the next digit of the answer. 
Result so far: 197449.1526
Subtracting 2358 from 2640 leaves us with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Moving on to step 13:
The number 393 fits into 2820 7 times, leaving a remainder of 69.
The number 7 becomes the next digit in our result. 
Result so far: 197449.15267
Subtracting 2751 from 2820 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 14:
690 divided by 393 is 1 with a remainder of 297.
Use 1 as the next digit of our solution. 
Result so far: 197449.152671
If we subtract 393 from 690, we get 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

On to step 15:
393 goes into 2970 7 times with a remainder of 219.
The number 7 becomes the next digit in our result. 
Result so far: 197449.1526717
The remainder is 219 after subtracting 2751 from 2970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Going ahead to step 16:
393 goes into 2190 5 times with a remainder of 225.
Use 5 as the next digit of our solution. 
Result so far: 197449.15267175
If we take 1965 away from 2190, we end up with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

The final result is 197449.15267175 with a remainder of 2.25e-07.
