12630009 ÷ 308 
We want to divide 12630009 by 308.

Advancing to step 1:
308 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 308

Moving on to step 2:
The number 308 fits into 12 0 times, leaving a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Fetch the next digit (6) from the dividend, attach it to 12 and continue: 126 / 308

Step 3:
If we divide 126 by 308, we get 0 and a remainder of 126.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 126 to get 126.
Bring next digit (3) of the dividend behind the 126 and repeat the process: 1263 / 308

Let's proceed to step 4:
The number 308 fits into 1263 4 times, leaving a remainder of 31.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 1232 from 1263 and we're left with 31.
Grab the next digit (0) from the dividend, add it to 31, then carry on: 310 / 308

Step 5:
The number 308 fits into 310 1 times, leaving a remainder of 2.
The next digit of our result is 1. 
Result so far: 41.0
If we take 308 away from 310, we end up with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 308

Going ahead to step 6:
20 divided by 308 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 410.0
Subtract 0 from 20 to get 20.
Fetch the next digit (0) from the dividend, attach it to 20 and continue: 200 / 308

Step 7:
308 goes into 200 0 times with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 4100.0
Deduct 0 from 200 and we're left with 200.
Grab the next digit (9) from the dividend, add it to 200, then carry on: 2009 / 308

Advancing to step 8:
If we divide 2009 by 308, we get 6 and a remainder of 161.
Record the quotient 6 as the next digit in the result. 
Result so far: 41006.0
The remainder is 161 after subtracting 1848 from 2009.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Advancing to step 9:
When dividing 1610 by 308, we get 5 with a remainder of 70.
The next digit of our result is 5. 
Result so far: 41006.5
Subtracting 1540 from 1610 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 10:
If we divide 700 by 308, we get 2 and a remainder of 84.
Record the quotient 2 as the next digit in the result. 
Result so far: 41006.52
Deduct 616 from 700 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 11:
If we divide 840 by 308, we get 2 and a remainder of 224.
Put 2 as the next digit of the answer. 
Result so far: 41006.522
Subtract 616 from 840 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

In conclusion, the division gives 41006.522 with a balance of 0.0224.
