212829 ÷ 86 
Our goal is to divide 212829 by 86.

Let's proceed to step 1:
2 divided by 86 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 86

Step 2:
The number 86 fits into 21 0 times, leaving a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Take the next digit (2) from the dividend and append it to 21, then repeat: 212 / 86

Moving on to step 3:
86 can be fit into 212 2 times, resulting in a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 172 from 212 to get 40.
Fetch the next digit (8) from the dividend, attach it to 40 and continue: 408 / 86

Step 4:
86 goes into 408 4 times with a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 24.0
Subtracting 344 from 408 leaves us with 64.
Fetch the next digit (2) from the dividend, attach it to 64 and continue: 642 / 86

Going ahead to step 5:
642 divided by 86 is 7 with a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 247.0
The remainder is 40 after subtracting 602 from 642.
Append the next digit (9) from the dividend to 40 and continue with: 409 / 86

Moving on to step 6:
409 divided by 86 is 4 with a remainder of 65.
The number 4 becomes the next digit in our result. 
Result so far: 2474.0
Deduct 344 from 409 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 7:
If we divide 650 by 86, we get 7 and a remainder of 48.
Write down 7 as next digit of the result. 
Result so far: 2474.7
Deduct 602 from 650 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 8:
86 goes into 480 5 times with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 2474.75
If we take 430 away from 480, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 9:
500 divided by 86 is 5 with a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 2474.755
Subtract 430 from 500 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

In conclusion, the division gives 2474.755 with a balance of 0.007.
