We're dividing 643683 by 79 
Let's see how many times 79 fits into 643683.

Moving on to step 1:
79 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 79

Let's proceed to step 2:
The number 79 fits into 64 0 times, leaving a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Include the next digit (3) from the dividend after 64, then repeat: 643 / 79

Step 3:
643 divided by 79 is 8 with a remainder of 11.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 632 from 643 and we're left with 11.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 79

On to step 4:
116 divided by 79 is 1 with a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
Subtracting 79 from 116 leaves us with 37.
Fetch the next digit (8) from the dividend, attach it to 37 and continue: 378 / 79

Step 5:
The number 79 fits into 378 4 times, leaving a remainder of 62.
Put 4 as the next digit of the answer. 
Result so far: 814.0
Deduct 316 from 378 and we're left with 62.
Grab the next digit (3) from the dividend, add it to 62, then carry on: 623 / 79

Let's proceed to step 6:
If we divide 623 by 79, we get 7 and a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 8147.0
Deduct 553 from 623 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 7:
79 can be fit into 700 8 times, resulting in a remainder of 68.
Write down 8 as next digit of the result. 
Result so far: 8147.8
If we take 632 away from 700, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 8:
79 goes into 680 8 times with a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 8147.88
Subtracting 632 from 680 leaves us 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.

In conclusion, the division gives 8147.88 with a balance of 0.048.
