810840 divided by 38 
We want to figure out the number of times 810840 can be divided by 38.

Going ahead to step 1:
38 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 38

Moving on to step 2:
81 divided by 38 is 2 with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 76 from 81 leaves us with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 38

Step 3:
When dividing 50 by 38, we get 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 21.0
Deduct 38 from 50 and we're left with 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 38

Going ahead to step 4:
If we divide 128 by 38, we get 3 and a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 213.0
Subtracting 114 from 128 leaves us with 14.
Append the next digit (4) from the dividend to 14 and continue with: 144 / 38

Moving on to step 5:
144 divided by 38 is 3 with a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 2133.0
The remainder is 30 after subtracting 114 from 144.
Grab the next digit (0) from the dividend, add it to 30, then carry on: 300 / 38

Let's proceed to step 6:
38 can be fit into 300 7 times, resulting in a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 21337.0
Deduct 266 from 300 and we're left 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 7:
The number 38 fits into 340 8 times, leaving a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 21337.8
If we subtract 304 from 340, we 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.

Step 8:
38 can be fit into 360 9 times, resulting in a remainder of 18.
The next digit of our result is 9. 
Result so far: 21337.89
The remainder is 18 after subtracting 342 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 9:
38 can be fit into 180 4 times, resulting in a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 21337.894
If we subtract 152 from 180, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 10:
If we divide 280 by 38, we get 7 and a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 21337.8947
Subtracting 266 from 280 leaves us 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.

Going ahead to step 11:
38 goes into 140 3 times with a remainder of 26.
Write down 3 as next digit of the result. 
Result so far: 21337.89473
Subtract 114 from 140 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 12:
The number 38 fits into 260 6 times, leaving a remainder of 32.
The next digit of our result is 6. 
Result so far: 21337.894736
The remainder is 32 after subtracting 228 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 13:
38 goes into 320 8 times with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 21337.8947368
If we take 304 away from 320, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 14:
If we divide 160 by 38, we get 4 and a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 21337.89473684
If we subtract 152 from 160, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 21337.89473684 and a remainder of 8e-09.
