80717954 ÷ 688 
We want to divide 80717954 by 688.

Let's proceed to step 1:
When dividing 8 by 688, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 688

Let's proceed to step 2:
688 can be fit into 80 0 times, resulting in a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Take the next digit (7) from the dividend and append it to 80, then repeat: 807 / 688

Step 3:
688 goes into 807 1 times with a remainder of 119.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 688 from 807, we get 119.
Fetch the next digit (1) from the dividend, attach it to 119 and continue: 1191 / 688

Step 4:
The number 688 fits into 1191 1 times, leaving a remainder of 503.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 688 from 1191 and we're left with 503.
Append the next digit (7) from the dividend to 503 and continue with: 5037 / 688

Moving on to step 5:
If we divide 5037 by 688, we get 7 and a remainder of 221.
Put 7 as the next digit of the answer. 
Result so far: 117.0
The remainder is 221 after subtracting 4816 from 5037.
Include the next digit (9) from the dividend after 221, then repeat: 2219 / 688

Moving on to step 6:
688 goes into 2219 3 times with a remainder of 155.
Put 3 as the next digit of the answer. 
Result so far: 1173.0
The remainder is 155 after subtracting 2064 from 2219.
Append the next digit (5) from the dividend to 155 and continue with: 1555 / 688

On to step 7:
The number 688 fits into 1555 2 times, leaving a remainder of 179.
The number 2 becomes the next digit in our result. 
Result so far: 11732.0
If we subtract 1376 from 1555, we get 179.
Include the next digit (4) from the dividend after 179, then repeat: 1794 / 688

Advancing to step 8:
1794 divided by 688 is 2 with a remainder of 418.
Write down 2 as next digit of the result. 
Result so far: 117322.0
Subtract 1376 from 1794 to get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Moving on to step 9:
688 can be fit into 4180 6 times, resulting in a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 117322.6
The remainder is 52 after subtracting 4128 from 4180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 10:
If we divide 520 by 688, we get 0 and a remainder of 520.
Record the quotient 0 as the next digit in the result. 
Result so far: 117322.6
If we take 0 away from 520, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Advancing to step 11:
The number 688 fits into 5200 7 times, leaving a remainder of 384.
Use 7 as the next digit of our solution. 
Result so far: 117322.607
The remainder is 384 after subtracting 4816 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 12:
688 goes into 3840 5 times with a remainder of 400.
Record the quotient 5 as the next digit in the result. 
Result so far: 117322.6075
The remainder is 400 after subtracting 3440 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 13:
When dividing 4000 by 688, we get 5 with a remainder of 560.
Use 5 as the next digit of our solution. 
Result so far: 117322.60755
If we subtract 3440 from 4000, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

The final result is 117322.60755 with a remainder of 0.00056.
