We look at the division of 643288 by 38 
Our goal is to divide 643288 by 38.

Moving on to step 1:
6 divided by 38 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 38

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
If we take 38 away from 64, we end up with 26.
Append the next digit (3) from the dividend to 26 and continue with: 263 / 38

On to step 3:
263 divided by 38 is 6 with a remainder of 35.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtract 228 from 263 to get 35.
Append the next digit (2) from the dividend to 35 and continue with: 352 / 38

Step 4:
352 divided by 38 is 9 with a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 169.0
If we take 342 away from 352, we end up with 10.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 38

Advancing to step 5:
The number 38 fits into 108 2 times, leaving a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 1692.0
If we subtract 76 from 108, we get 32.
Bring next digit (8) of the dividend behind the 32 and repeat the process: 328 / 38

On to step 6:
38 goes into 328 8 times with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 16928.0
If we subtract 304 from 328, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 7:
When dividing 240 by 38, we get 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 16928.6
The remainder is 12 after subtracting 228 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 8:
38 goes into 120 3 times with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 16928.63
If we subtract 114 from 120, 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.

Step 9:
If we divide 60 by 38, we get 1 and a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 16928.631
Subtract 38 from 60 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 10:
The number 38 fits into 220 5 times, leaving a remainder of 30.
The next digit of our result is 5. 
Result so far: 16928.6315
If we take 190 away from 220, we end up 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.

Going ahead to step 11:
If we divide 300 by 38, we get 7 and a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 16928.63157
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.

Going ahead to step 12:
If we divide 340 by 38, we get 8 and a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 16928.631578
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.

On to step 13:
38 goes into 360 9 times with a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 16928.6315789
Subtract 342 from 360 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 14:
The number 38 fits into 180 4 times, leaving a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 16928.63157894
Deduct 152 from 180 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Our division results in 16928.63157894 with a remaining 2.8e-08.
