We divide 640023 by 49
We want to divide 640023 by 49.

On to step 1:
When dividing 6 by 49, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 49

Let's proceed to step 2:
49 goes into 64 1 times with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 49 from 64, we get 15.
Include the next digit (0) from the dividend after 15, then repeat: 150 / 49

On to step 3:
The number 49 fits into 150 3 times, leaving a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 13.0
The remainder is 3 after subtracting 147 from 150.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 49

Moving on to step 4:
When dividing 30 by 49, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 130.0
If we take 0 away from 30, we end up with 30.
Take the next digit (2) from the dividend and append it to 30, then repeat: 302 / 49

Step 5:
49 goes into 302 6 times with a remainder of 8.
The next digit of our result is 6. 
Result so far: 1306.0
Deduct 294 from 302 and we're left with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 49

Let's proceed to step 6:
83 divided by 49 is 1 with a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 13061.0
The remainder is 34 after subtracting 49 from 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 7:
49 goes into 340 6 times with a remainder of 46.
The next digit of our result is 6. 
Result so far: 13061.6
If we subtract 294 from 340, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 8:
49 goes into 460 9 times with a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 13061.69
Deduct 441 from 460 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 9:
49 can be fit into 190 3 times, resulting in a remainder of 43.
The next digit of our result is 3. 
Result so far: 13061.693
Deduct 147 from 190 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 10:
The number 49 fits into 430 8 times, leaving a remainder of 38.
The next digit of our result is 8. 
Result so far: 13061.6938
Subtracting 392 from 430 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 11:
49 can be fit into 380 7 times, resulting in a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 13061.69387
Subtracting 343 from 380 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 12:
When dividing 370 by 49, we get 7 with a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 13061.693877
If we take 343 away from 370, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The final result is 13061.693877 with a remainder of 2.7e-06.
