Let's divide 31144955 by 686
We want to divide 31144955 by 686.

On to step 1:
When dividing 3 by 686, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 686

On to step 2:
686 can be fit into 31 0 times, resulting in a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Take the next digit (1) from the dividend and append it to 31, then repeat: 311 / 686

Advancing to step 3:
686 can be fit into 311 0 times, resulting in a remainder of 311.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 311, we get 311.
Take the next digit (4) from the dividend and append it to 311, then repeat: 3114 / 686

Moving on to step 4:
When dividing 3114 by 686, we get 4 with a remainder of 370.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 2744 from 3114 and we're left with 370.
Bring next digit (4) of the dividend behind the 370 and repeat the process: 3704 / 686

Step 5:
When dividing 3704 by 686, we get 5 with a remainder of 274.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
Subtract 3430 from 3704 to get 274.
Bring next digit (9) of the dividend behind the 274 and repeat the process: 2749 / 686

Moving on to step 6:
686 can be fit into 2749 4 times, resulting in a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 454.0
If we take 2744 away from 2749, we end up with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 686

Going ahead to step 7:
686 goes into 55 0 times with a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 4540.0
If we subtract 0 from 55, we get 55.
Append the next digit (5) from the dividend to 55 and continue with: 555 / 686

Step 8:
When dividing 555 by 686, we get 0 with a remainder of 555.
Use 0 as the next digit of our solution. 
Result so far: 45400.0
Subtracting 0 from 555 leaves us with 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Moving on to step 9:
686 goes into 5550 8 times with a remainder of 62.
Write down 8 as next digit of the result. 
Result so far: 45400.8
If we subtract 5488 from 5550, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 10:
If we divide 620 by 686, we get 0 and a remainder of 620.
Put 0 as the next digit of the answer. 
Result so far: 45400.8
The remainder is 620 after subtracting 0 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Moving on to step 11:
When dividing 6200 by 686, we get 9 with a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 45400.809
The remainder is 26 after subtracting 6174 from 6200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 12:
If we divide 260 by 686, we get 0 and a remainder of 260.
The next digit of our result is 0. 
Result so far: 45400.809
Subtracting 0 from 260 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 13:
The number 686 fits into 2600 3 times, leaving a remainder of 542.
The next digit of our result is 3. 
Result so far: 45400.80903
If we take 2058 away from 2600, we end up with 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Going ahead to step 14:
When dividing 5420 by 686, we get 7 with a remainder of 618.
Use 7 as the next digit of our solution. 
Result so far: 45400.809037
If we subtract 4802 from 5420, we get 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Let's proceed to step 15:
When dividing 6180 by 686, we get 9 with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 45400.8090379
Subtracting 6174 from 6180 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 16:
The number 686 fits into 60 0 times, leaving a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 45400.8090379
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The quotient of the division is 45400.8090379, and the remainder is 6e-08.
