618638 divided by 13 
Our goal is to divide 618638 by 13.

Let's proceed to step 1:
If we divide 6 by 13, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 13

Step 2:
If we divide 61 by 13, we get 4 and a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 52 from 61 to get 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 13

Advancing to step 3:
98 divided by 13 is 7 with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
If we subtract 91 from 98, we get 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 13

Let's proceed to step 4:
The number 13 fits into 76 5 times, leaving a remainder of 11.
The next digit of our result is 5. 
Result so far: 475.0
If we subtract 65 from 76, we get 11.
Bring next digit (3) of the dividend behind the 11 and repeat the process: 113 / 13

On to step 5:
When dividing 113 by 13, we get 8 with a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 4758.0
Subtract 104 from 113 to get 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 13

On to step 6:
The number 13 fits into 98 7 times, leaving a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 47587.0
If we take 91 away from 98, we end up 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.

Going ahead to step 7:
70 divided by 13 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 47587.5
The remainder is 5 after subtracting 65 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
13 goes into 50 3 times with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 47587.53
The remainder is 11 after subtracting 39 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 9:
If we divide 110 by 13, we get 8 and a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 47587.538
Deduct 104 from 110 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 10:
The number 13 fits into 60 4 times, leaving a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 47587.5384
Deduct 52 from 60 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.

Moving on to step 11:
13 can be fit into 80 6 times, resulting in a remainder of 2.
The next digit of our result is 6. 
Result so far: 47587.53846
Deduct 78 from 80 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.

On to step 12:
The number 13 fits into 20 1 times, leaving a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 47587.538461
If we subtract 13 from 20, we 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.

Moving on to step 13:
70 divided by 13 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 47587.5384615
Subtract 65 from 70 to 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.

Advancing to step 14:
13 can be fit into 50 3 times, resulting in a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 47587.53846153
Deduct 39 from 50 and we're left 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.

The quotient of the division is 47587.53846153, and the remainder is 1.1e-08.
