42630515 divided by 12 
We want to divide 42630515 by 12.

Going ahead to step 1:
When dividing 4 by 12, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 12

Let's proceed to step 2:
42 divided by 12 is 3 with a remainder of 6.
The next digit of our result is 3. 
Result so far: 3.0
If we take 36 away from 42, we end up with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 12

Advancing to step 3:
66 divided by 12 is 5 with a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 35.0
Deduct 60 from 66 and we're left with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 12

Moving on to step 4:
12 goes into 63 5 times with a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 355.0
If we take 60 away from 63, we end up with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 12

On to step 5:
The number 12 fits into 30 2 times, leaving a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 3552.0
Deduct 24 from 30 and we're left with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 12

Moving on to step 6:
65 divided by 12 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 35525.0
The remainder is 5 after subtracting 60 from 65.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 12

Let's proceed to step 7:
When dividing 51 by 12, we get 4 with a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 355254.0
If we take 48 away from 51, we end up with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 12

Let's proceed to step 8:
When dividing 35 by 12, we get 2 with a remainder of 11.
The next digit of our result is 2. 
Result so far: 3552542.0
Subtract 24 from 35 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
110 divided by 12 is 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 3552542.9
Subtracting 108 from 110 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 10:
If we divide 20 by 12, we get 1 and a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 3552542.91
The remainder is 8 after subtracting 12 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 3552542.916
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
The number 12 fits into 80 6 times, leaving a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 3552542.9166
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 3552542.9166 with a remaining 8e-05.
