Let's divide 84351202 by 800
Let's see how many times 800 fits into 84351202.

Going ahead to step 1:
8 divided by 800 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 800

Moving on to step 2:
800 can be fit into 84 0 times, resulting in a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 84 leaves us with 84.
Bring next digit (3) of the dividend behind the 84 and repeat the process: 843 / 800

Going ahead to step 3:
843 divided by 800 is 1 with a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 800 from 843, we get 43.
Bring next digit (5) of the dividend behind the 43 and repeat the process: 435 / 800

Let's proceed to step 4:
435 divided by 800 is 0 with a remainder of 435.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 435, we get 435.
Include the next digit (1) from the dividend after 435, then repeat: 4351 / 800

Advancing to step 5:
800 can be fit into 4351 5 times, resulting in a remainder of 351.
Put 5 as the next digit of the answer. 
Result so far: 105.0
Deduct 4000 from 4351 and we're left with 351.
Fetch the next digit (2) from the dividend, attach it to 351 and continue: 3512 / 800

Moving on to step 6:
800 goes into 3512 4 times with a remainder of 312.
Put 4 as the next digit of the answer. 
Result so far: 1054.0
If we subtract 3200 from 3512, we get 312.
Take the next digit (0) from the dividend and append it to 312, then repeat: 3120 / 800

Advancing to step 7:
When dividing 3120 by 800, we get 3 with a remainder of 720.
Put 3 as the next digit of the answer. 
Result so far: 10543.0
The remainder is 720 after subtracting 2400 from 3120.
Include the next digit (2) from the dividend after 720, then repeat: 7202 / 800

Advancing to step 8:
800 goes into 7202 9 times with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 105439.0
If we subtract 7200 from 7202, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 9:
When dividing 20 by 800, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 105439.0
The remainder is 20 after subtracting 0 from 20.
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 10:
The number 800 fits into 200 0 times, leaving a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 105439.0
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final outcome is 105439.0, with a leftover of 0.2.
