We're dividing 51605 by 79 
We want to figure out the number of times 51605 can be divided by 79.

Step 1:
If we divide 5 by 79, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 79

Going ahead to step 2:
51 divided by 79 is 0 with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Include the next digit (6) from the dividend after 51, then repeat: 516 / 79

On to step 3:
516 divided by 79 is 6 with a remainder of 42.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 474 from 516 to get 42.
Take the next digit (0) from the dividend and append it to 42, then repeat: 420 / 79

On to step 4:
The number 79 fits into 420 5 times, leaving a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 65.0
Subtract 395 from 420 to get 25.
Grab the next digit (5) from the dividend, add it to 25, then carry on: 255 / 79

Advancing to step 5:
If we divide 255 by 79, we get 3 and a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 653.0
If we subtract 237 from 255, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 6:
When dividing 180 by 79, we get 2 with a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 653.2
The remainder is 22 after subtracting 158 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 7:
When dividing 220 by 79, we get 2 with a remainder of 62.
The next digit of our result is 2. 
Result so far: 653.22
If we subtract 158 from 220, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

After the division, we end up with 653.22 and a remainder of 0.062.
