Let's divide 430766 by 86
We want to divide 430766 by 86.

Moving on to step 1:
The number 86 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 86

Advancing to step 2:
86 goes into 43 0 times with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Bring next digit (0) of the dividend behind the 43 and repeat the process: 430 / 86

Going ahead to step 3:
When dividing 430 by 86, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 0 after subtracting 430 from 430.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 86

Moving on to step 4:
When dividing 7 by 86, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 86

Step 5:
The number 86 fits into 76 0 times, leaving a remainder of 76.
Write down 0 as next digit of the result. 
Result so far: 500.0
Subtracting 0 from 76 leaves us with 76.
Include the next digit (6) from the dividend after 76, then repeat: 766 / 86

On to step 6:
The number 86 fits into 766 8 times, leaving a remainder of 78.
Put 8 as the next digit of the answer. 
Result so far: 5008.0
Subtracting 688 from 766 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 7:
86 can be fit into 780 9 times, resulting in a remainder of 6.
The next digit of our result is 9. 
Result so far: 5008.9
If we subtract 774 from 780, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
86 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 5008.9
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
If we divide 600 by 86, we get 6 and a remainder of 84.
Put 6 as the next digit of the answer. 
Result so far: 5008.906
Deduct 516 from 600 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 10:
840 divided by 86 is 9 with a remainder of 66.
Put 9 as the next digit of the answer. 
Result so far: 5008.9069
If we subtract 774 from 840, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 11:
86 can be fit into 660 7 times, resulting in a remainder of 58.
The next digit of our result is 7. 
Result so far: 5008.90697
If we subtract 602 from 660, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 12:
The number 86 fits into 580 6 times, leaving a remainder of 64.
The next digit of our result is 6. 
Result so far: 5008.906976
The remainder is 64 after subtracting 516 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 13:
The number 86 fits into 640 7 times, leaving a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 5008.9069767
Subtract 602 from 640 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 14:
86 goes into 380 4 times with a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 5008.90697674
Subtract 344 from 380 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

In conclusion, the division gives 5008.90697674 with a balance of 3.6e-08.
