644847 ÷ 38 
We're looking to find how many times 38 goes into 644847.

Let's proceed to step 1:
The number 38 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 38

Step 2:
When dividing 64 by 38, we get 1 with a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 38 from 64, we get 26.
Append the next digit (4) from the dividend to 26 and continue with: 264 / 38

Advancing to step 3:
When dividing 264 by 38, we get 6 with a remainder of 36.
The next digit of our result is 6. 
Result so far: 16.0
Deduct 228 from 264 and we're left with 36.
Include the next digit (8) from the dividend after 36, then repeat: 368 / 38

On to step 4:
When dividing 368 by 38, we get 9 with a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 169.0
Subtracting 342 from 368 leaves us with 26.
Include the next digit (4) from the dividend after 26, then repeat: 264 / 38

Step 5:
When dividing 264 by 38, we get 6 with a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 1696.0
Subtract 228 from 264 to get 36.
Bring next digit (7) of the dividend behind the 36 and repeat the process: 367 / 38

Step 6:
38 goes into 367 9 times with a remainder of 25.
The next digit of our result is 9. 
Result so far: 16969.0
If we take 342 away from 367, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 7:
When dividing 250 by 38, we get 6 with a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 16969.6
If we take 228 away from 250, we end up 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.

Going ahead to step 8:
38 goes into 220 5 times with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 16969.65
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.

Let's proceed to step 9:
300 divided by 38 is 7 with a remainder of 34.
The next digit of our result is 7. 
Result so far: 16969.657
The remainder is 34 after subtracting 266 from 300.
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 10:
340 divided by 38 is 8 with a remainder of 36.
The next digit of our result is 8. 
Result so far: 16969.6578
The remainder is 36 after subtracting 304 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 11:
360 divided by 38 is 9 with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 16969.65789
Subtracting 342 from 360 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 12:
38 goes into 180 4 times with a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 16969.657894
The remainder is 28 after subtracting 152 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 13:
If we divide 280 by 38, we get 7 and a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 16969.6578947
If we take 266 away from 280, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 14:
If we divide 140 by 38, we get 3 and a remainder of 26.
Write down 3 as next digit of the result. 
Result so far: 16969.65789473
Deduct 114 from 140 and we're left 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.

Our division results in 16969.65789473 with a remaining 2.6e-08.
