We look at the division of 34129808 by 810 
Our goal is to divide 34129808 by 810.

Advancing to step 1:
When dividing 3 by 810, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 810

On to step 2:
34 divided by 810 is 0 with a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Fetch the next digit (1) from the dividend, attach it to 34 and continue: 341 / 810

Moving on to step 3:
If we divide 341 by 810, we get 0 and a remainder of 341.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 341, we get 341.
Bring next digit (2) of the dividend behind the 341 and repeat the process: 3412 / 810

Step 4:
3412 divided by 810 is 4 with a remainder of 172.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 172 after subtracting 3240 from 3412.
Bring next digit (9) of the dividend behind the 172 and repeat the process: 1729 / 810

Advancing to step 5:
If we divide 1729 by 810, we get 2 and a remainder of 109.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
The remainder is 109 after subtracting 1620 from 1729.
Take the next digit (8) from the dividend and append it to 109, then repeat: 1098 / 810

Moving on to step 6:
1098 divided by 810 is 1 with a remainder of 288.
Put 1 as the next digit of the answer. 
Result so far: 421.0
Subtract 810 from 1098 to get 288.
Grab the next digit (0) from the dividend, add it to 288, then carry on: 2880 / 810

Going ahead to step 7:
2880 divided by 810 is 3 with a remainder of 450.
Record the quotient 3 as the next digit in the result. 
Result so far: 4213.0
If we subtract 2430 from 2880, we get 450.
Include the next digit (8) from the dividend after 450, then repeat: 4508 / 810

Step 8:
810 can be fit into 4508 5 times, resulting in a remainder of 458.
The next digit of our result is 5. 
Result so far: 42135.0
If we take 4050 away from 4508, we end up with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Advancing to step 9:
The number 810 fits into 4580 5 times, leaving a remainder of 530.
Use 5 as the next digit of our solution. 
Result so far: 42135.5
Subtracting 4050 from 4580 leaves us with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Moving on to step 10:
If we divide 5300 by 810, we get 6 and a remainder of 440.
Record the quotient 6 as the next digit in the result. 
Result so far: 42135.56
If we subtract 4860 from 5300, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 11:
4400 divided by 810 is 5 with a remainder of 350.
The next digit of our result is 5. 
Result so far: 42135.565
Subtracting 4050 from 4400 leaves us with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 12:
When dividing 3500 by 810, we get 4 with a remainder of 260.
The next digit of our result is 4. 
Result so far: 42135.5654
Deduct 3240 from 3500 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 13:
When dividing 2600 by 810, we get 3 with a remainder of 170.
The number 3 becomes the next digit in our result. 
Result so far: 42135.56543
Subtracting 2430 from 2600 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 14:
1700 divided by 810 is 2 with a remainder of 80.
The next digit of our result is 2. 
Result so far: 42135.565432
Subtracting 1620 from 1700 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 15:
When dividing 800 by 810, we get 0 with a remainder of 800.
The next digit of our result is 0. 
Result so far: 42135.565432
If we subtract 0 from 800, we get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Let's proceed to step 16:
810 goes into 8000 9 times with a remainder of 710.
Use 9 as the next digit of our solution. 
Result so far: 42135.56543209
If we take 7290 away from 8000, we end up with 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Our division results in 42135.56543209 with a remaining 7.1e-07.
