649440 ÷ 38 
Let's see how many times 38 fits into 649440.

Step 1:
38 goes into 6 0 times 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 / 38

Advancing to step 2:
64 divided by 38 is 1 with a remainder of 26.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 38 from 64 and we're left with 26.
Fetch the next digit (9) from the dividend, attach it to 26 and continue: 269 / 38

Advancing to step 3:
If we divide 269 by 38, we get 7 and a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Deduct 266 from 269 and we're left with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 38

Let's proceed to step 4:
The number 38 fits into 34 0 times, leaving a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 170.0
Subtract 0 from 34 to get 34.
Append the next digit (4) from the dividend to 34 and continue with: 344 / 38

Let's proceed to step 5:
344 divided by 38 is 9 with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 1709.0
The remainder is 2 after subtracting 342 from 344.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 38

On to step 6:
If we divide 20 by 38, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 17090.0
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 7:
38 goes into 200 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 17090.5
If we subtract 190 from 200, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
When dividing 100 by 38, we get 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 17090.52
If we take 76 away from 100, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 9:
240 divided by 38 is 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 17090.526
Subtracting 228 from 240 leaves us 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.

Advancing to step 10:
When dividing 120 by 38, we get 3 with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 17090.5263
Deduct 114 from 120 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 11:
The number 38 fits into 60 1 times, leaving a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 17090.52631
Subtracting 38 from 60 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 12:
220 divided by 38 is 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 17090.526315
Subtracting 190 from 220 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 13:
38 can be fit into 300 7 times, resulting in a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 17090.5263157
Subtracting 266 from 300 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 14:
The number 38 fits into 340 8 times, leaving a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 17090.52631578
Deduct 304 from 340 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final result is 17090.52631578 with a remainder of 3.6e-08.
