810042 ÷ 35 
We're looking to find how many times 35 goes into 810042.

Step 1:
35 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 35

Advancing to step 2:
81 divided by 35 is 2 with a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 70 from 81 leaves us with 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 35

On to step 3:
35 can be fit into 110 3 times, resulting in a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Subtract 105 from 110 to get 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 35

Going ahead to step 4:
35 goes into 50 1 times with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 231.0
The remainder is 15 after subtracting 35 from 50.
Fetch the next digit (4) from the dividend, attach it to 15 and continue: 154 / 35

Advancing to step 5:
The number 35 fits into 154 4 times, leaving a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 2314.0
Subtracting 140 from 154 leaves us with 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 35

Let's proceed to step 6:
35 goes into 142 4 times with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 23144.0
Subtracting 140 from 142 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
If we divide 20 by 35, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 23144.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
200 divided by 35 is 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 23144.05
If we take 175 away from 200, 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.

Let's proceed to step 9:
If we divide 250 by 35, we get 7 and a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 23144.057
If we take 245 away from 250, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 10:
50 divided by 35 is 1 with a remainder of 15.
The next digit of our result is 1. 
Result so far: 23144.0571
Deduct 35 from 50 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 11:
The number 35 fits into 150 4 times, leaving a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 23144.05714
If we subtract 140 from 150, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
100 divided by 35 is 2 with a remainder of 30.
Record the quotient 2 as the next digit in the result. 
Result so far: 23144.057142
The remainder is 30 after subtracting 70 from 100.
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 13:
300 divided by 35 is 8 with a remainder of 20.
The next digit of our result is 8. 
Result so far: 23144.0571428
The remainder is 20 after subtracting 280 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 14:
If we divide 200 by 35, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 23144.05714285
Subtracting 175 from 200 leaves us 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.

After the division, we end up with 23144.05714285 and a remainder of 2.5e-08.
