12135606 divided by 630 
We want to figure out the number of times 12135606 can be divided by 630.

Going ahead to step 1:
630 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 630

Let's proceed to step 2:
When dividing 12 by 630, we get 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 630

Let's proceed to step 3:
630 goes into 121 0 times with a remainder of 121.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 121 and we're left with 121.
Fetch the next digit (3) from the dividend, attach it to 121 and continue: 1213 / 630

Moving on to step 4:
630 can be fit into 1213 1 times, resulting in a remainder of 583.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 630 from 1213 and we're left with 583.
Bring next digit (5) of the dividend behind the 583 and repeat the process: 5835 / 630

Moving on to step 5:
If we divide 5835 by 630, we get 9 and a remainder of 165.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtracting 5670 from 5835 leaves us with 165.
Fetch the next digit (6) from the dividend, attach it to 165 and continue: 1656 / 630

Advancing to step 6:
If we divide 1656 by 630, we get 2 and a remainder of 396.
Use 2 as the next digit of our solution. 
Result so far: 192.0
Subtract 1260 from 1656 to get 396.
Include the next digit (0) from the dividend after 396, then repeat: 3960 / 630

On to step 7:
If we divide 3960 by 630, we get 6 and a remainder of 180.
Put 6 as the next digit of the answer. 
Result so far: 1926.0
If we take 3780 away from 3960, we end up with 180.
Include the next digit (6) from the dividend after 180, then repeat: 1806 / 630

Moving on to step 8:
1806 divided by 630 is 2 with a remainder of 546.
Use 2 as the next digit of our solution. 
Result so far: 19262.0
Subtracting 1260 from 1806 leaves us with 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

On to step 9:
The number 630 fits into 5460 8 times, leaving a remainder of 420.
Record the quotient 8 as the next digit in the result. 
Result so far: 19262.8
Subtract 5040 from 5460 to get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 10:
630 can be fit into 4200 6 times, resulting in a remainder of 420.
Put 6 as the next digit of the answer. 
Result so far: 19262.86
If we subtract 3780 from 4200, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Going ahead to step 11:
4200 divided by 630 is 6 with a remainder of 420.
The number 6 becomes the next digit in our result. 
Result so far: 19262.866
Subtract 3780 from 4200 to get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

The final outcome is 19262.866, with a leftover of 0.042.
