We divide 642689 by 13
Our goal is to divide 642689 by 13.

Advancing to step 1:
6 divided by 13 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 13

Let's proceed to step 2:
When dividing 64 by 13, we get 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 52 from 64 and we're left with 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 13

Let's proceed to step 3:
The number 13 fits into 122 9 times, leaving a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
Subtracting 117 from 122 leaves us with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 13

Let's proceed to step 4:
13 can be fit into 56 4 times, resulting in a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 494.0
If we take 52 away from 56, we end up with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 13

Let's proceed to step 5:
If we divide 48 by 13, we get 3 and a remainder of 9.
The next digit of our result is 3. 
Result so far: 4943.0
If we subtract 39 from 48, we get 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 13

Let's proceed to step 6:
If we divide 99 by 13, we get 7 and a remainder of 8.
The next digit of our result is 7. 
Result so far: 49437.0
Subtract 91 from 99 to get 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 7:
80 divided by 13 is 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 49437.6
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.

Let's proceed to step 8:
20 divided by 13 is 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 49437.61
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.

On to step 9:
When dividing 70 by 13, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 49437.615
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 10:
If we divide 50 by 13, we get 3 and a remainder of 11.
The next digit of our result is 3. 
Result so far: 49437.6153
If we subtract 39 from 50, we 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.

Advancing to step 11:
13 can be fit into 110 8 times, resulting in a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 49437.61538
If we subtract 104 from 110, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 12:
13 goes into 60 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 49437.615384
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.

Step 13:
80 divided by 13 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 49437.6153846
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.

Advancing to step 14:
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: 49437.61538461
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.

After the division, we end up with 49437.61538461 and a remainder of 7e-09.
