We're dividing 34128331 by 800 
Let's see how many times 800 fits into 34128331.

Step 1:
800 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 800

Advancing to step 2:
34 divided by 800 is 0 with a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Append the next digit (1) from the dividend to 34 and continue with: 341 / 800

Advancing to step 3:
The number 800 fits into 341 0 times, leaving a remainder of 341.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 341 to get 341.
Take the next digit (2) from the dividend and append it to 341, then repeat: 3412 / 800

Let's proceed to step 4:
3412 divided by 800 is 4 with a remainder of 212.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 3200 away from 3412, we end up with 212.
Bring next digit (8) of the dividend behind the 212 and repeat the process: 2128 / 800

Moving on to step 5:
The number 800 fits into 2128 2 times, leaving a remainder of 528.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
Subtracting 1600 from 2128 leaves us with 528.
Append the next digit (3) from the dividend to 528 and continue with: 5283 / 800

Moving on to step 6:
The number 800 fits into 5283 6 times, leaving a remainder of 483.
The number 6 becomes the next digit in our result. 
Result so far: 426.0
Subtract 4800 from 5283 to get 483.
Fetch the next digit (3) from the dividend, attach it to 483 and continue: 4833 / 800

Step 7:
800 goes into 4833 6 times with a remainder of 33.
The next digit of our result is 6. 
Result so far: 4266.0
If we take 4800 away from 4833, we end up with 33.
Grab the next digit (1) from the dividend, add it to 33, then carry on: 331 / 800

Going ahead to step 8:
The number 800 fits into 331 0 times, leaving a remainder of 331.
The number 0 becomes the next digit in our result. 
Result so far: 42660.0
If we take 0 away from 331, we end up with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Advancing to step 9:
The number 800 fits into 3310 4 times, leaving a remainder of 110.
Write down 4 as next digit of the result. 
Result so far: 42660.4
If we subtract 3200 from 3310, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 10:
800 goes into 1100 1 times with a remainder of 300.
Record the quotient 1 as the next digit in the result. 
Result so far: 42660.41
The remainder is 300 after subtracting 800 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 11:
When dividing 3000 by 800, we get 3 with a remainder of 600.
Record the quotient 3 as the next digit in the result. 
Result so far: 42660.413
The remainder is 600 after subtracting 2400 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Let's proceed to step 12:
800 can be fit into 6000 7 times, resulting in a remainder of 400.
Write down 7 as next digit of the result. 
Result so far: 42660.4137
If we take 5600 away from 6000, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 13:
800 goes into 4000 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 42660.41375
Subtracting 4000 from 4000 leaves us 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.

On to step 14:
When dividing 0 by 800, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 42660.41375
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.

Moving on to step 15:
800 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 42660.41375
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.

In conclusion, the division gives 42660.41375 with a balance of 0.0.
