688178 ÷ 31 
We want to divide 688178 by 31.

On to step 1:
The number 31 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 31

Going ahead to step 2:
31 goes into 68 2 times with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 62 from 68 and we're left with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 31

On to step 3:
The number 31 fits into 68 2 times, leaving a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 22.0
If we take 62 away from 68, we end up with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 31

Moving on to step 4:
The number 31 fits into 61 1 times, leaving a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 221.0
If we take 31 away from 61, we end up with 30.
Append the next digit (7) from the dividend to 30 and continue with: 307 / 31

Let's proceed to step 5:
31 can be fit into 307 9 times, resulting in a remainder of 28.
The next digit of our result is 9. 
Result so far: 2219.0
If we subtract 279 from 307, we get 28.
Append the next digit (8) from the dividend to 28 and continue with: 288 / 31

Step 6:
31 goes into 288 9 times with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 22199.0
Subtracting 279 from 288 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
If we divide 90 by 31, we get 2 and a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 22199.2
Subtracting 62 from 90 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 8:
If we divide 280 by 31, we get 9 and a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 22199.29
Subtract 279 from 280 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
10 divided by 31 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 22199.29
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
When dividing 100 by 31, we get 3 with a remainder of 7.
The next digit of our result is 3. 
Result so far: 22199.2903
Subtract 93 from 100 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 11:
When dividing 70 by 31, we get 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 22199.29032
The remainder is 8 after subtracting 62 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
If we divide 80 by 31, we get 2 and a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 22199.290322
If we subtract 62 from 80, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The quotient of the division is 22199.290322, and the remainder is 1.8e-06.
