86340546 ÷ 203 
Our goal is to divide 86340546 by 203.

Going ahead to step 1:
If we divide 8 by 203, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 203

Step 2:
If we divide 86 by 203, we get 0 and a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Append the next digit (3) from the dividend to 86 and continue with: 863 / 203

Moving on to step 3:
203 goes into 863 4 times with a remainder of 51.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 812 from 863, we get 51.
Append the next digit (4) from the dividend to 51 and continue with: 514 / 203

Step 4:
203 can be fit into 514 2 times, resulting in a remainder of 108.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Subtracting 406 from 514 leaves us with 108.
Fetch the next digit (0) from the dividend, attach it to 108 and continue: 1080 / 203

Moving on to step 5:
When dividing 1080 by 203, we get 5 with a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 425.0
If we take 1015 away from 1080, we end up with 65.
Grab the next digit (5) from the dividend, add it to 65, then carry on: 655 / 203

Advancing to step 6:
203 goes into 655 3 times with a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 4253.0
Subtract 609 from 655 to get 46.
Include the next digit (4) from the dividend after 46, then repeat: 464 / 203

Let's proceed to step 7:
203 goes into 464 2 times with a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 42532.0
Subtracting 406 from 464 leaves us with 58.
Append the next digit (6) from the dividend to 58 and continue with: 586 / 203

Step 8:
203 goes into 586 2 times with a remainder of 180.
The next digit of our result is 2. 
Result so far: 425322.0
The remainder is 180 after subtracting 406 from 586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 9:
The number 203 fits into 1800 8 times, leaving a remainder of 176.
Write down 8 as next digit of the result. 
Result so far: 425322.8
Subtract 1624 from 1800 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 10:
203 goes into 1760 8 times with a remainder of 136.
The number 8 becomes the next digit in our result. 
Result so far: 425322.88
Subtract 1624 from 1760 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

In conclusion, the division gives 425322.88 with a balance of 0.136.
