We look at the division of 434463 by 86 
Let's see how many times 86 fits into 434463.

Step 1:
When dividing 4 by 86, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 86

Going ahead to step 2:
The number 86 fits into 43 0 times, leaving a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Append the next digit (4) from the dividend to 43 and continue with: 434 / 86

Step 3:
434 divided by 86 is 5 with a remainder of 4.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 430 from 434 to get 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 86

Going ahead to step 4:
When dividing 44 by 86, we get 0 with a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
If we subtract 0 from 44, we get 44.
Append the next digit (6) from the dividend to 44 and continue with: 446 / 86

On to step 5:
If we divide 446 by 86, we get 5 and a remainder of 16.
Put 5 as the next digit of the answer. 
Result so far: 505.0
Subtract 430 from 446 to get 16.
Fetch the next digit (3) from the dividend, attach it to 16 and continue: 163 / 86

Moving on to step 6:
86 goes into 163 1 times with a remainder of 77.
Put 1 as the next digit of the answer. 
Result so far: 5051.0
If we subtract 86 from 163, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Advancing to step 7:
86 can be fit into 770 8 times, resulting in a remainder of 82.
The next digit of our result is 8. 
Result so far: 5051.8
Subtracting 688 from 770 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 8:
86 goes into 820 9 times with a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 5051.89
If we subtract 774 from 820, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 9:
460 divided by 86 is 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 5051.895
Subtracting 430 from 460 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
86 goes into 300 3 times with a remainder of 42.
The next digit of our result is 3. 
Result so far: 5051.8953
If we take 258 away from 300, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 11:
If we divide 420 by 86, we get 4 and a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 5051.89534
Subtract 344 from 420 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 12:
The number 86 fits into 760 8 times, leaving a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 5051.895348
If we take 688 away from 760, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 13:
86 goes into 720 8 times with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 5051.8953488
The remainder is 32 after subtracting 688 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 5051.8953488 with a balance of 3.2e-07.
