78889388 ÷ 763 
We want to divide 78889388 by 763.

Moving on to step 1:
763 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 763

On to step 2:
763 can be fit into 78 0 times, resulting in a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Bring next digit (8) of the dividend behind the 78 and repeat the process: 788 / 763

Step 3:
763 goes into 788 1 times with a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 763 from 788 to get 25.
Append the next digit (8) from the dividend to 25 and continue with: 258 / 763

Step 4:
258 divided by 763 is 0 with a remainder of 258.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 258 leaves us with 258.
Append the next digit (9) from the dividend to 258 and continue with: 2589 / 763

Let's proceed to step 5:
When dividing 2589 by 763, we get 3 with a remainder of 300.
Use 3 as the next digit of our solution. 
Result so far: 103.0
If we take 2289 away from 2589, we end up with 300.
Fetch the next digit (3) from the dividend, attach it to 300 and continue: 3003 / 763

Moving on to step 6:
3003 divided by 763 is 3 with a remainder of 714.
The next digit of our result is 3. 
Result so far: 1033.0
If we take 2289 away from 3003, we end up with 714.
Fetch the next digit (8) from the dividend, attach it to 714 and continue: 7148 / 763

On to step 7:
If we divide 7148 by 763, we get 9 and a remainder of 281.
Put 9 as the next digit of the answer. 
Result so far: 10339.0
Deduct 6867 from 7148 and we're left with 281.
Append the next digit (8) from the dividend to 281 and continue with: 2818 / 763

Advancing to step 8:
The number 763 fits into 2818 3 times, leaving a remainder of 529.
Put 3 as the next digit of the answer. 
Result so far: 103393.0
The remainder is 529 after subtracting 2289 from 2818.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5290, and continue the process.

Going ahead to step 9:
5290 divided by 763 is 6 with a remainder of 712.
Record the quotient 6 as the next digit in the result. 
Result so far: 103393.6
If we subtract 4578 from 5290, we get 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

Advancing to step 10:
763 can be fit into 7120 9 times, resulting in a remainder of 253.
The next digit of our result is 9. 
Result so far: 103393.69
If we subtract 6867 from 7120, we get 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Advancing to step 11:
When dividing 2530 by 763, we get 3 with a remainder of 241.
The number 3 becomes the next digit in our result. 
Result so far: 103393.693
Subtracting 2289 from 2530 leaves us with 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Step 12:
The number 763 fits into 2410 3 times, leaving a remainder of 121.
The number 3 becomes the next digit in our result. 
Result so far: 103393.6933
The remainder is 121 after subtracting 2289 from 2410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

After the division, we end up with 103393.6933 and a remainder of 0.00121.
