646237 ÷ 38 
We're looking to find how many times 38 goes into 646237.

On to step 1:
6 divided by 38 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 38

Advancing to step 2:
When dividing 64 by 38, we get 1 with a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 38 from 64 to get 26.
Take the next digit (6) from the dividend and append it to 26, then repeat: 266 / 38

Going ahead to step 3:
When dividing 266 by 38, we get 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 17.0
The remainder is 0 after subtracting 266 from 266.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 38

Moving on to step 4:
When dividing 2 by 38, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 170.0
If we subtract 0 from 2, we get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 38

Going ahead to step 5:
If we divide 23 by 38, we get 0 and a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 1700.0
If we take 0 away from 23, we end up with 23.
Append the next digit (7) from the dividend to 23 and continue with: 237 / 38

Going ahead to step 6:
38 can be fit into 237 6 times, resulting in a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 17006.0
If we subtract 228 from 237, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
38 goes into 90 2 times with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 17006.2
If we subtract 76 from 90, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
When dividing 140 by 38, we get 3 with a remainder of 26.
Write down 3 as next digit of the result. 
Result so far: 17006.23
Subtracting 114 from 140 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 9:
38 can be fit into 260 6 times, resulting in a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 17006.236
Subtract 228 from 260 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 10:
If we divide 320 by 38, we get 8 and a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 17006.2368
Subtract 304 from 320 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
160 divided by 38 is 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 17006.23684
The remainder is 8 after subtracting 152 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
38 goes into 80 2 times with a remainder of 4.
The next digit of our result is 2. 
Result so far: 17006.236842
Deduct 76 from 80 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 13:
40 divided by 38 is 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 17006.2368421
The remainder is 2 after subtracting 38 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 14:
20 divided by 38 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 17006.2368421
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 17006.2368421 with a remainder of 2e-08.
