We're dividing 801890 by 34 
We want to figure out the number of times 801890 can be divided by 34.

On to step 1:
If we divide 8 by 34, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 34

Moving on to step 2:
34 goes into 80 2 times with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 68 from 80 and we're left with 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 34

Going ahead to step 3:
The number 34 fits into 121 3 times, leaving a remainder of 19.
The next digit of our result is 3. 
Result so far: 23.0
Subtract 102 from 121 to get 19.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 34

On to step 4:
34 goes into 198 5 times with a remainder of 28.
Put 5 as the next digit of the answer. 
Result so far: 235.0
Deduct 170 from 198 and we're left with 28.
Grab the next digit (9) from the dividend, add it to 28, then carry on: 289 / 34

Going ahead to step 5:
34 goes into 289 8 times with a remainder of 17.
Put 8 as the next digit of the answer. 
Result so far: 2358.0
If we subtract 272 from 289, we get 17.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 34

Step 6:
When dividing 170 by 34, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 23585.0
If we subtract 170 from 170, we 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 7:
34 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 23585.0
Deduct 0 from 0 and we're left 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.

Let's proceed to step 8:
When dividing 0 by 34, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 23585.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 23585.0 with a remaining 0.0.
