Let's divide 12909631 by 622
Let's see how many times 622 fits into 12909631.

On to step 1:
When dividing 1 by 622, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 622

Step 2:
The number 622 fits into 12 0 times, leaving a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 622

On to step 3:
622 goes into 129 0 times with a remainder of 129.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 129 after subtracting 0 from 129.
Bring next digit (0) of the dividend behind the 129 and repeat the process: 1290 / 622

Let's proceed to step 4:
622 goes into 1290 2 times with a remainder of 46.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 46 after subtracting 1244 from 1290.
Bring next digit (9) of the dividend behind the 46 and repeat the process: 469 / 622

Moving on to step 5:
If we divide 469 by 622, we get 0 and a remainder of 469.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Deduct 0 from 469 and we're left with 469.
Fetch the next digit (6) from the dividend, attach it to 469 and continue: 4696 / 622

Let's proceed to step 6:
If we divide 4696 by 622, we get 7 and a remainder of 342.
The number 7 becomes the next digit in our result. 
Result so far: 207.0
If we take 4354 away from 4696, we end up with 342.
Fetch the next digit (3) from the dividend, attach it to 342 and continue: 3423 / 622

Going ahead to step 7:
When dividing 3423 by 622, we get 5 with a remainder of 313.
The next digit of our result is 5. 
Result so far: 2075.0
If we take 3110 away from 3423, we end up with 313.
Append the next digit (1) from the dividend to 313 and continue with: 3131 / 622

Step 8:
If we divide 3131 by 622, we get 5 and a remainder of 21.
Write down 5 as next digit of the result. 
Result so far: 20755.0
Subtracting 3110 from 3131 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 9:
622 can be fit into 210 0 times, resulting in a remainder of 210.
The number 0 becomes the next digit in our result. 
Result so far: 20755.0
Subtracting 0 from 210 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 10:
622 goes into 2100 3 times with a remainder of 234.
The next digit of our result is 3. 
Result so far: 20755.03
Subtracting 1866 from 2100 leaves us with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Going ahead to step 11:
The number 622 fits into 2340 3 times, leaving a remainder of 474.
Write down 3 as next digit of the result. 
Result so far: 20755.033
The remainder is 474 after subtracting 1866 from 2340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Our division results in 20755.033 with a remaining 0.0474.
