We look at the division of 78534279 by 688 
Let's see how many times 688 fits into 78534279.

Advancing to step 1:
The number 688 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 688

Advancing to step 2:
If we divide 78 by 688, we get 0 and a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Fetch the next digit (5) from the dividend, attach it to 78 and continue: 785 / 688

Advancing to step 3:
When dividing 785 by 688, we get 1 with a remainder of 97.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 688 from 785, we get 97.
Grab the next digit (3) from the dividend, add it to 97, then carry on: 973 / 688

Advancing to step 4:
If we divide 973 by 688, we get 1 and a remainder of 285.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we subtract 688 from 973, we get 285.
Grab the next digit (4) from the dividend, add it to 285, then carry on: 2854 / 688

Let's proceed to step 5:
If we divide 2854 by 688, we get 4 and a remainder of 102.
Record the quotient 4 as the next digit in the result. 
Result so far: 114.0
If we take 2752 away from 2854, we end up with 102.
Bring next digit (2) of the dividend behind the 102 and repeat the process: 1022 / 688

Going ahead to step 6:
When dividing 1022 by 688, we get 1 with a remainder of 334.
Use 1 as the next digit of our solution. 
Result so far: 1141.0
Subtracting 688 from 1022 leaves us with 334.
Take the next digit (7) from the dividend and append it to 334, then repeat: 3347 / 688

Moving on to step 7:
3347 divided by 688 is 4 with a remainder of 595.
Write down 4 as next digit of the result. 
Result so far: 11414.0
If we take 2752 away from 3347, we end up with 595.
Include the next digit (9) from the dividend after 595, then repeat: 5959 / 688

Moving on to step 8:
5959 divided by 688 is 8 with a remainder of 455.
Put 8 as the next digit of the answer. 
Result so far: 114148.0
If we subtract 5504 from 5959, we get 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Going ahead to step 9:
The number 688 fits into 4550 6 times, leaving a remainder of 422.
Record the quotient 6 as the next digit in the result. 
Result so far: 114148.6
Subtracting 4128 from 4550 leaves us with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Going ahead to step 10:
4220 divided by 688 is 6 with a remainder of 92.
Write down 6 as next digit of the result. 
Result so far: 114148.66
Subtract 4128 from 4220 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

The final outcome is 114148.66, with a leftover of 0.092.
