Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 83

Going ahead to step 2:
The number 83 fits into 64 0 times, leaving a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Take the next digit (3) from the dividend and append it to 64, then repeat: 643 / 83

Advancing to step 3:
If we divide 643 by 83, we get 7 and a remainder of 62.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 62 after subtracting 581 from 643.

Going ahead to step 5:
403 divided by 83 is 4 with a remainder of 71.
Record the quotient 4 as the next digit in the result. 
Result so far: 774.0
Subtracting 332 from 403 leaves us with 71.
Grab the next digit (5) from the dividend, add it to 71, then carry on: 715 / 83

Going ahead to step 6:
83 can be fit into 715 8 times, resulting in a remainder of 51.
The number 8 becomes the next digit in our result. 
Result so far: 7748.0
Subtract 664 from 715 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 7:
83 goes into 510 6 times with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 7748.6
If we take 498 away from 510, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
The number 83 fits into 120 1 times, leaving a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 7748.61
Subtracting 83 from 120 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 9:
The number 83 fits into 370 4 times, leaving a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 7748.614
Subtract 332 from 370 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.

On to step 10:
380 divided by 83 is 4 with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 7748.6144
If we take 332 away from 380, we end up 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.

Our division results in 7748.6144 with a remaining 0.00048.
