77352905 ÷ 863 
Our goal is to divide 77352905 by 863.

On to step 1:
7 divided by 863 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 863

Moving on to step 2:
The number 863 fits into 77 0 times, leaving a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Fetch the next digit (3) from the dividend, attach it to 77 and continue: 773 / 863

Going ahead to step 3:
When dividing 773 by 863, we get 0 with a remainder of 773.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 773 to get 773.
Append the next digit (5) from the dividend to 773 and continue with: 7735 / 863

Let's proceed to step 4:
When dividing 7735 by 863, we get 8 with a remainder of 831.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 6904 from 7735 leaves us with 831.
Bring next digit (2) of the dividend behind the 831 and repeat the process: 8312 / 863

Step 5:
863 goes into 8312 9 times with a remainder of 545.
The next digit of our result is 9. 
Result so far: 89.0
Deduct 7767 from 8312 and we're left with 545.
Take the next digit (9) from the dividend and append it to 545, then repeat: 5459 / 863

Step 6:
5459 divided by 863 is 6 with a remainder of 281.
Record the quotient 6 as the next digit in the result. 
Result so far: 896.0
Subtracting 5178 from 5459 leaves us with 281.
Fetch the next digit (0) from the dividend, attach it to 281 and continue: 2810 / 863

Advancing to step 7:
If we divide 2810 by 863, we get 3 and a remainder of 221.
Record the quotient 3 as the next digit in the result. 
Result so far: 8963.0
Deduct 2589 from 2810 and we're left with 221.
Grab the next digit (5) from the dividend, add it to 221, then carry on: 2215 / 863

On to step 8:
If we divide 2215 by 863, we get 2 and a remainder of 489.
Use 2 as the next digit of our solution. 
Result so far: 89632.0
The remainder is 489 after subtracting 1726 from 2215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

On to step 9:
863 can be fit into 4890 5 times, resulting in a remainder of 575.
Use 5 as the next digit of our solution. 
Result so far: 89632.5
If we subtract 4315 from 4890, we get 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Moving on to step 10:
If we divide 5750 by 863, we get 6 and a remainder of 572.
Use 6 as the next digit of our solution. 
Result so far: 89632.56
Subtracting 5178 from 5750 leaves us with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Step 11:
If we divide 5720 by 863, we get 6 and a remainder of 542.
Put 6 as the next digit of the answer. 
Result so far: 89632.566
Subtracting 5178 from 5720 leaves us with 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

The final outcome is 89632.566, with a leftover of 0.0542.
