670339 ÷ 38 
We want to divide 670339 by 38.

Going ahead to step 1:
When dividing 6 by 38, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 38

Step 2:
38 can be fit into 67 1 times, resulting in a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 38 from 67 leaves us with 29.
Fetch the next digit (0) from the dividend, attach it to 29 and continue: 290 / 38

Moving on to step 3:
When dividing 290 by 38, we get 7 with a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtract 266 from 290 to get 24.
Fetch the next digit (3) from the dividend, attach it to 24 and continue: 243 / 38

Going ahead to step 4:
When dividing 243 by 38, we get 6 with a remainder of 15.
The next digit of our result is 6. 
Result so far: 176.0
If we take 228 away from 243, we end up with 15.
Include the next digit (3) from the dividend after 15, then repeat: 153 / 38

Advancing to step 5:
When dividing 153 by 38, we get 4 with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 1764.0
Subtracting 152 from 153 leaves us with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 38

On to step 6:
The number 38 fits into 19 0 times, leaving a remainder of 19.
The next digit of our result is 0. 
Result so far: 17640.0
The remainder is 19 after subtracting 0 from 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
The number 38 fits into 190 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 17640.5
Subtract 190 from 190 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
0 divided by 38 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 17640.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
The number 38 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 17640.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 17640.5, with a leftover of 0.0.
