Let's divide 646385 by 13
We want to figure out the number of times 646385 can be divided by 13.

Let's proceed to step 1:
6 divided by 13 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 13

Advancing to step 2:
If we divide 64 by 13, we get 4 and a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 12 after subtracting 52 from 64.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 13

Step 3:
126 divided by 13 is 9 with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 49.0
Subtract 117 from 126 to get 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 13

Step 4:
When dividing 93 by 13, we get 7 with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 497.0
If we subtract 91 from 93, we get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 13

Let's proceed to step 5:
13 can be fit into 28 2 times, resulting in a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 4972.0
Subtract 26 from 28 to get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 13

Going ahead to step 6:
13 can be fit into 25 1 times, resulting in a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 49721.0
If we take 13 away from 25, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
When dividing 120 by 13, we get 9 with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 49721.9
If we take 117 away from 120, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 8:
30 divided by 13 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 49721.92
If we take 26 away from 30, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
40 divided by 13 is 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 49721.923
If we take 39 away from 40, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 10:
10 divided by 13 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 49721.923
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
13 can be fit into 100 7 times, resulting in a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 49721.92307
Deduct 91 from 100 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 12:
90 divided by 13 is 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 49721.923076
Deduct 78 from 90 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 13:
If we divide 120 by 13, we get 9 and a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 49721.9230769
The remainder is 3 after subtracting 117 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 14:
If we divide 30 by 13, we get 2 and a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 49721.92307692
Subtract 26 from 30 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 49721.92307692 with a remaining 4e-09.
