We divide 2150744 by 686
Our goal is to divide 2150744 by 686.

Step 1:
686 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 686

Going ahead to step 2:
21 divided by 686 is 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Append the next digit (5) from the dividend to 21 and continue with: 215 / 686

Let's proceed to step 3:
686 can be fit into 215 0 times, resulting in a remainder of 215.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 215 leaves us with 215.
Append the next digit (0) from the dividend to 215 and continue with: 2150 / 686

Step 4:
The number 686 fits into 2150 3 times, leaving a remainder of 92.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 2058 from 2150 and we're left with 92.
Include the next digit (7) from the dividend after 92, then repeat: 927 / 686

Going ahead to step 5:
686 can be fit into 927 1 times, resulting in a remainder of 241.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
If we take 686 away from 927, we end up with 241.
Take the next digit (4) from the dividend and append it to 241, then repeat: 2414 / 686

Going ahead to step 6:
686 can be fit into 2414 3 times, resulting in a remainder of 356.
Record the quotient 3 as the next digit in the result. 
Result so far: 313.0
Subtract 2058 from 2414 to get 356.
Include the next digit (4) from the dividend after 356, then repeat: 3564 / 686

Advancing to step 7:
When dividing 3564 by 686, we get 5 with a remainder of 134.
Write down 5 as next digit of the result. 
Result so far: 3135.0
If we subtract 3430 from 3564, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

On to step 8:
686 goes into 1340 1 times with a remainder of 654.
Put 1 as the next digit of the answer. 
Result so far: 3135.1
Deduct 686 from 1340 and we're left with 654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Going ahead to step 9:
When dividing 6540 by 686, we get 9 with a remainder of 366.
Use 9 as the next digit of our solution. 
Result so far: 3135.19
Subtract 6174 from 6540 to get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Step 10:
3660 divided by 686 is 5 with a remainder of 230.
The next digit of our result is 5. 
Result so far: 3135.195
Subtract 3430 from 3660 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 11:
If we divide 2300 by 686, we get 3 and a remainder of 242.
The number 3 becomes the next digit in our result. 
Result so far: 3135.1953
If we take 2058 away from 2300, we end up with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

On to step 12:
When dividing 2420 by 686, we get 3 with a remainder of 362.
The next digit of our result is 3. 
Result so far: 3135.19533
Subtracting 2058 from 2420 leaves us with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

After the division, we end up with 3135.19533 and a remainder of 0.000362.
