We're dividing 630645 by 13 
Our goal is to divide 630645 by 13.

Going ahead to step 1:
13 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 13

Going ahead to step 2:
When dividing 63 by 13, we get 4 with a remainder of 11.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 52 away from 63, we end up with 11.
Include the next digit (0) from the dividend after 11, then repeat: 110 / 13

Going ahead to step 3:
13 goes into 110 8 times with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 48.0
Subtract 104 from 110 to get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 13

Advancing to step 4:
13 can be fit into 66 5 times, resulting in a remainder of 1.
The next digit of our result is 5. 
Result so far: 485.0
If we subtract 65 from 66, we get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 13

Let's proceed to step 5:
13 goes into 14 1 times with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 4851.0
The remainder is 1 after subtracting 13 from 14.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 13

Advancing to step 6:
If we divide 15 by 13, we get 1 and a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 48511.0
Deduct 13 from 15 and we're left 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.

Going ahead to step 7:
20 divided by 13 is 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 48511.1
Subtract 13 from 20 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 8:
13 can be fit into 70 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 48511.15
Deduct 65 from 70 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 9:
When dividing 50 by 13, we get 3 with a remainder of 11.
The next digit of our result is 3. 
Result so far: 48511.153
Subtracting 39 from 50 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 10:
110 divided by 13 is 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 48511.1538
The remainder is 6 after subtracting 104 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 11:
13 goes into 60 4 times with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 48511.15384
Subtracting 52 from 60 leaves us 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.

On to step 12:
If we divide 80 by 13, we get 6 and a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 48511.153846
The remainder is 2 after subtracting 78 from 80.
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 13:
13 can be fit into 20 1 times, resulting in a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 48511.1538461
Subtracting 13 from 20 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 14:
The number 13 fits into 70 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 48511.15384615
If we subtract 65 from 70, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 48511.15384615, and the remainder is 5e-09.
