We look at the division of 834479 by 86 
We're looking to find how many times 86 goes into 834479.

Step 1:
86 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 86

Moving on to step 2:
The number 86 fits into 83 0 times, leaving a remainder of 83.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Bring next digit (4) of the dividend behind the 83 and repeat the process: 834 / 86

On to step 3:
86 can be fit into 834 9 times, resulting in a remainder of 60.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 774 from 834 to get 60.
Append the next digit (4) from the dividend to 60 and continue with: 604 / 86

Going ahead to step 4:
604 divided by 86 is 7 with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 97.0
Deduct 602 from 604 and we're left with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 86

Step 5:
The number 86 fits into 27 0 times, leaving a remainder of 27.
Put 0 as the next digit of the answer. 
Result so far: 970.0
Subtract 0 from 27 to get 27.
Fetch the next digit (9) from the dividend, attach it to 27 and continue: 279 / 86

Going ahead to step 6:
86 can be fit into 279 3 times, resulting in a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 9703.0
The remainder is 21 after subtracting 258 from 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
If we divide 210 by 86, we get 2 and a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 9703.2
Subtracting 172 from 210 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 8:
86 can be fit into 380 4 times, resulting in a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 9703.24
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.

Going ahead to step 9:
86 can be fit into 360 4 times, resulting in a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 9703.244
Deduct 344 from 360 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 9703.244, and the remainder is 0.0016.
