We're dividing 51758538 by 688 
Let's see how many times 688 fits into 51758538.

Moving on to step 1:
The number 688 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 688

Step 2:
When dividing 51 by 688, we get 0 with a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Include the next digit (7) from the dividend after 51, then repeat: 517 / 688

On to step 3:
688 goes into 517 0 times with a remainder of 517.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 517 after subtracting 0 from 517.
Append the next digit (5) from the dividend to 517 and continue with: 5175 / 688

Moving on to step 4:
The number 688 fits into 5175 7 times, leaving a remainder of 359.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 4816 from 5175 and we're left with 359.
Include the next digit (8) from the dividend after 359, then repeat: 3598 / 688

Advancing to step 5:
If we divide 3598 by 688, we get 5 and a remainder of 158.
The next digit of our result is 5. 
Result so far: 75.0
Deduct 3440 from 3598 and we're left with 158.
Take the next digit (5) from the dividend and append it to 158, then repeat: 1585 / 688

Advancing to step 6:
688 goes into 1585 2 times with a remainder of 209.
Record the quotient 2 as the next digit in the result. 
Result so far: 752.0
The remainder is 209 after subtracting 1376 from 1585.
Fetch the next digit (3) from the dividend, attach it to 209 and continue: 2093 / 688

Let's proceed to step 7:
688 goes into 2093 3 times with a remainder of 29.
Record the quotient 3 as the next digit in the result. 
Result so far: 7523.0
Subtracting 2064 from 2093 leaves us with 29.
Append the next digit (8) from the dividend to 29 and continue with: 298 / 688

Going ahead to step 8:
The number 688 fits into 298 0 times, leaving a remainder of 298.
Use 0 as the next digit of our solution. 
Result so far: 75230.0
If we subtract 0 from 298, we get 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Let's proceed to step 9:
688 goes into 2980 4 times with a remainder of 228.
The number 4 becomes the next digit in our result. 
Result so far: 75230.4
Deduct 2752 from 2980 and we're left with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 10:
When dividing 2280 by 688, we get 3 with a remainder of 216.
The number 3 becomes the next digit in our result. 
Result so far: 75230.43
If we take 2064 away from 2280, we end up with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 11:
When dividing 2160 by 688, we get 3 with a remainder of 96.
Use 3 as the next digit of our solution. 
Result so far: 75230.433
If we subtract 2064 from 2160, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

After the division, we end up with 75230.433 and a remainder of 0.0096.
