Let's divide 829400 by 86
We want to figure out the number of times 829400 can be divided by 86.

On to step 1:
8 divided by 86 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 86

Advancing to step 2:
When dividing 82 by 86, we get 0 with a remainder of 82.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 82 to get 82.
Take the next digit (9) from the dividend and append it to 82, then repeat: 829 / 86

Advancing to step 3:
The number 86 fits into 829 9 times, leaving a remainder of 55.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 774 from 829 to get 55.
Include the next digit (4) from the dividend after 55, then repeat: 554 / 86

On to step 4:
554 divided by 86 is 6 with a remainder of 38.
The number 6 becomes the next digit in our result. 
Result so far: 96.0
If we subtract 516 from 554, we get 38.
Include the next digit (0) from the dividend after 38, then repeat: 380 / 86

Let's proceed to step 5:
The number 86 fits into 380 4 times, leaving a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 964.0
Subtracting 344 from 380 leaves us with 36.
Bring next digit (0) of the dividend behind the 36 and repeat the process: 360 / 86

Moving on to step 6:
The number 86 fits into 360 4 times, leaving a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 9644.0
The remainder is 16 after subtracting 344 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
When dividing 160 by 86, we get 1 with a remainder of 74.
Record the quotient 1 as the next digit in the result. 
Result so far: 9644.1
Deduct 86 from 160 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 8:
740 divided by 86 is 8 with a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 9644.18
If we take 688 away from 740, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 9:
If we divide 520 by 86, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 9644.186
Subtract 516 from 520 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
If we divide 40 by 86, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 9644.186
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
When dividing 400 by 86, we get 4 with a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 9644.18604
The remainder is 56 after subtracting 344 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 12:
The number 86 fits into 560 6 times, leaving a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 9644.186046
If we subtract 516 from 560, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 13:
The number 86 fits into 440 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 9644.1860465
Subtracting 430 from 440 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 14:
86 goes into 100 1 times with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 9644.18604651
If we take 86 away from 100, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 9644.18604651 with a remainder of 1.4e-08.
