Let's divide 640681 by 38
We're looking to find how many times 38 goes into 640681.

Let's proceed to step 1:
38 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 38

Moving on to step 2:
64 divided by 38 is 1 with a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 38 from 64 leaves us with 26.
Append the next digit (0) from the dividend to 26 and continue with: 260 / 38

Going ahead to step 3:
38 can be fit into 260 6 times, resulting in a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Deduct 228 from 260 and we're left with 32.
Append the next digit (6) from the dividend to 32 and continue with: 326 / 38

Going ahead to step 4:
If we divide 326 by 38, we get 8 and a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 168.0
If we subtract 304 from 326, we get 22.
Append the next digit (8) from the dividend to 22 and continue with: 228 / 38

Let's proceed to step 5:
38 goes into 228 6 times with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 1686.0
Subtract 228 from 228 to get 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 38

Moving on to step 6:
If we divide 1 by 38, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 16860.0
The remainder is 1 after subtracting 0 from 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
38 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 16860.0
If we take 0 away from 10, we end up 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.

Going ahead to step 8:
If we divide 100 by 38, we get 2 and a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 16860.02
The remainder is 24 after subtracting 76 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 9:
38 goes into 240 6 times with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 16860.026
If we take 228 away from 240, 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.

Going ahead to step 10:
If we divide 120 by 38, we get 3 and a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 16860.0263
Subtract 114 from 120 to 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 11:
60 divided by 38 is 1 with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 16860.02631
The remainder is 22 after subtracting 38 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 12:
The number 38 fits into 220 5 times, leaving a remainder of 30.
The next digit of our result is 5. 
Result so far: 16860.026315
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:
If we divide 300 by 38, we get 7 and a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 16860.0263157
If we take 266 away from 300, we end up 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.

Advancing to step 14:
340 divided by 38 is 8 with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 16860.02631578
Subtract 304 from 340 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

In conclusion, the division gives 16860.02631578 with a balance of 3.6e-08.
