We divide 680400 by 38
We want to figure out the number of times 680400 can be divided by 38.

Going ahead 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
Subtract 0 from 6 to get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 38

Going ahead to step 2:
38 goes into 68 1 times with a remainder of 30.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 38 from 68, we get 30.
Fetch the next digit (0) from the dividend, attach it to 30 and continue: 300 / 38

Moving on to step 3:
The number 38 fits into 300 7 times, leaving a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 17.0
The remainder is 34 after subtracting 266 from 300.
Fetch the next digit (4) from the dividend, attach it to 34 and continue: 344 / 38

Moving on to step 4:
The number 38 fits into 344 9 times, leaving a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 179.0
Subtract 342 from 344 to get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 38

Going ahead to step 5:
20 divided by 38 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 1790.0
Deduct 0 from 20 and we're left with 20.
Fetch the next digit (0) from the dividend, attach it to 20 and continue: 200 / 38

Advancing to step 6:
When dividing 200 by 38, we get 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 17905.0
Subtracting 190 from 200 leaves us 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.

On to step 7:
If we divide 100 by 38, we get 2 and a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 17905.2
If we take 76 away from 100, we end up with 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 8:
When dividing 240 by 38, we get 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 17905.26
Subtracting 228 from 240 leaves us 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.

Moving on to step 9:
38 goes into 120 3 times with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 17905.263
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 10:
The number 38 fits into 60 1 times, leaving a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 17905.2631
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.

Let's proceed to step 11:
220 divided by 38 is 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 17905.26315
Deduct 190 from 220 and we're left 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.

Moving on to step 12:
If we divide 300 by 38, we get 7 and a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 17905.263157
If we subtract 266 from 300, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 13:
If we divide 340 by 38, we get 8 and a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 17905.2631578
Subtracting 304 from 340 leaves us with 36.
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 14:
38 goes into 360 9 times with a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 17905.26315789
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.

The final result is 17905.26315789 with a remainder of 1.8e-08.
