Let's divide 78980998 by 688
Our goal is to divide 78980998 by 688.

Step 1:
7 divided by 688 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 688

Moving on to step 2:
When dividing 78 by 688, we get 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Bring next digit (9) of the dividend behind the 78 and repeat the process: 789 / 688

Step 3:
When dividing 789 by 688, we get 1 with a remainder of 101.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 688 from 789 leaves us with 101.
Take the next digit (8) from the dividend and append it to 101, then repeat: 1018 / 688

Let's proceed to step 4:
If we divide 1018 by 688, we get 1 and a remainder of 330.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 688 away from 1018, we end up with 330.
Append the next digit (0) from the dividend to 330 and continue with: 3300 / 688

Going ahead to step 5:
When dividing 3300 by 688, we get 4 with a remainder of 548.
Record the quotient 4 as the next digit in the result. 
Result so far: 114.0
If we subtract 2752 from 3300, we get 548.
Bring next digit (9) of the dividend behind the 548 and repeat the process: 5489 / 688

Going ahead to step 6:
If we divide 5489 by 688, we get 7 and a remainder of 673.
The next digit of our result is 7. 
Result so far: 1147.0
If we subtract 4816 from 5489, we get 673.
Include the next digit (9) from the dividend after 673, then repeat: 6739 / 688

Moving on to step 7:
688 can be fit into 6739 9 times, resulting in a remainder of 547.
The number 9 becomes the next digit in our result. 
Result so far: 11479.0
The remainder is 547 after subtracting 6192 from 6739.
Bring next digit (8) of the dividend behind the 547 and repeat the process: 5478 / 688

Step 8:
The number 688 fits into 5478 7 times, leaving a remainder of 662.
Put 7 as the next digit of the answer. 
Result so far: 114797.0
The remainder is 662 after subtracting 4816 from 5478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

Advancing to step 9:
If we divide 6620 by 688, we get 9 and a remainder of 428.
Record the quotient 9 as the next digit in the result. 
Result so far: 114797.9
The remainder is 428 after subtracting 6192 from 6620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Moving on to step 10:
4280 divided by 688 is 6 with a remainder of 152.
Use 6 as the next digit of our solution. 
Result so far: 114797.96
The remainder is 152 after subtracting 4128 from 4280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 11:
If we divide 1520 by 688, we get 2 and a remainder of 144.
Write down 2 as next digit of the result. 
Result so far: 114797.962
Subtract 1376 from 1520 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 12:
The number 688 fits into 1440 2 times, leaving a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 114797.9622
Subtract 1376 from 1440 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 114797.9622 and a remainder of 0.00064.
