86852109 ÷ 200 
We want to divide 86852109 by 200.

On to step 1:
200 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 200

Let's proceed to step 2:
86 divided by 200 is 0 with a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Include the next digit (8) from the dividend after 86, then repeat: 868 / 200

On to step 3:
When dividing 868 by 200, we get 4 with a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 800 away from 868, we end up with 68.
Take the next digit (5) from the dividend and append it to 68, then repeat: 685 / 200

Step 4:
When dividing 685 by 200, we get 3 with a remainder of 85.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
If we subtract 600 from 685, we get 85.
Bring next digit (2) of the dividend behind the 85 and repeat the process: 852 / 200

Moving on to step 5:
200 can be fit into 852 4 times, resulting in a remainder of 52.
Record the quotient 4 as the next digit in the result. 
Result so far: 434.0
The remainder is 52 after subtracting 800 from 852.
Append the next digit (1) from the dividend to 52 and continue with: 521 / 200

Step 6:
If we divide 521 by 200, we get 2 and a remainder of 121.
The next digit of our result is 2. 
Result so far: 4342.0
If we subtract 400 from 521, we get 121.
Take the next digit (0) from the dividend and append it to 121, then repeat: 1210 / 200

Let's proceed to step 7:
200 goes into 1210 6 times with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 43426.0
Subtracting 1200 from 1210 leaves us with 10.
Fetch the next digit (9) from the dividend, attach it to 10 and continue: 109 / 200

Step 8:
200 can be fit into 109 0 times, resulting in a remainder of 109.
Record the quotient 0 as the next digit in the result. 
Result so far: 434260.0
Deduct 0 from 109 and we're left with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Let's proceed to step 9:
When dividing 1090 by 200, we get 5 with a remainder of 90.
Record the quotient 5 as the next digit in the result. 
Result so far: 434260.5
If we take 1000 away from 1090, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 10:
200 can be fit into 900 4 times, resulting in a remainder of 100.
Put 4 as the next digit of the answer. 
Result so far: 434260.54
If we take 800 away from 900, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 11:
1000 divided by 200 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 434260.545
Subtract 1000 from 1000 to 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.

Going ahead to step 12:
When dividing 0 by 200, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 434260.545
Subtracting 0 from 0 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.

Step 13:
200 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 434260.545
If we take 0 away from 0, we end up 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.

The final outcome is 434260.545, with a leftover of 0.0.
