We're dividing 83131778 by 688 
We want to divide 83131778 by 688.

Moving on to step 1:
The number 688 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 688

Step 2:
If we divide 83 by 688, we get 0 and a remainder of 83.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 83 to get 83.
Append the next digit (1) from the dividend to 83 and continue with: 831 / 688

Let's proceed to step 3:
831 divided by 688 is 1 with a remainder of 143.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 688 from 831 and we're left with 143.
Grab the next digit (3) from the dividend, add it to 143, then carry on: 1433 / 688

Moving on to step 4:
The number 688 fits into 1433 2 times, leaving a remainder of 57.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 1376 from 1433, we get 57.
Include the next digit (1) from the dividend after 57, then repeat: 571 / 688

On to step 5:
The number 688 fits into 571 0 times, leaving a remainder of 571.
The next digit of our result is 0. 
Result so far: 120.0
Subtract 0 from 571 to get 571.
Bring next digit (7) of the dividend behind the 571 and repeat the process: 5717 / 688

Advancing to step 6:
688 can be fit into 5717 8 times, resulting in a remainder of 213.
Put 8 as the next digit of the answer. 
Result so far: 1208.0
Subtract 5504 from 5717 to get 213.
Include the next digit (7) from the dividend after 213, then repeat: 2137 / 688

Step 7:
If we divide 2137 by 688, we get 3 and a remainder of 73.
The number 3 becomes the next digit in our result. 
Result so far: 12083.0
Deduct 2064 from 2137 and we're left with 73.
Append the next digit (8) from the dividend to 73 and continue with: 738 / 688

Let's proceed to step 8:
If we divide 738 by 688, we get 1 and a remainder of 50.
Put 1 as the next digit of the answer. 
Result so far: 120831.0
Subtracting 688 from 738 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 9:
When dividing 500 by 688, we get 0 with a remainder of 500.
The number 0 becomes the next digit in our result. 
Result so far: 120831.0
Subtract 0 from 500 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

On to step 10:
The number 688 fits into 5000 7 times, leaving a remainder of 184.
Put 7 as the next digit of the answer. 
Result so far: 120831.07
The remainder is 184 after subtracting 4816 from 5000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Advancing to step 11:
The number 688 fits into 1840 2 times, leaving a remainder of 464.
Write down 2 as next digit of the result. 
Result so far: 120831.072
If we take 1376 away from 1840, we end up with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Moving on to step 12:
If we divide 4640 by 688, we get 6 and a remainder of 512.
The number 6 becomes the next digit in our result. 
Result so far: 120831.0726
Subtracting 4128 from 4640 leaves us with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Going ahead to step 13:
5120 divided by 688 is 7 with a remainder of 304.
Use 7 as the next digit of our solution. 
Result so far: 120831.07267
If we subtract 4816 from 5120, we get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Let's proceed to step 14:
3040 divided by 688 is 4 with a remainder of 288.
The next digit of our result is 4. 
Result so far: 120831.072674
If we subtract 2752 from 3040, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Going ahead to step 15:
2880 divided by 688 is 4 with a remainder of 128.
Write down 4 as next digit of the result. 
Result so far: 120831.0726744
If we subtract 2752 from 2880, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The final result is 120831.0726744 with a remainder of 1.28e-06.
