We're dividing 51025766 by 79 
Let's see how many times 79 fits into 51025766.

Let's proceed to step 1:
When dividing 5 by 79, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 79

Advancing to step 2:
79 goes into 51 0 times with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Bring next digit (0) of the dividend behind the 51 and repeat the process: 510 / 79

On to step 3:
79 goes into 510 6 times with a remainder of 36.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 474 from 510 leaves us with 36.
Include the next digit (2) from the dividend after 36, then repeat: 362 / 79

Advancing to step 4:
79 can be fit into 362 4 times, resulting in a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
If we subtract 316 from 362, we get 46.
Take the next digit (5) from the dividend and append it to 46, then repeat: 465 / 79

Step 5:
465 divided by 79 is 5 with a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 645.0
Subtracting 395 from 465 leaves us with 70.
Fetch the next digit (7) from the dividend, attach it to 70 and continue: 707 / 79

Moving on to step 6:
The number 79 fits into 707 8 times, leaving a remainder of 75.
Use 8 as the next digit of our solution. 
Result so far: 6458.0
Subtracting 632 from 707 leaves us with 75.
Take the next digit (6) from the dividend and append it to 75, then repeat: 756 / 79

Let's proceed to step 7:
When dividing 756 by 79, we get 9 with a remainder of 45.
Record the quotient 9 as the next digit in the result. 
Result so far: 64589.0
If we subtract 711 from 756, we get 45.
Bring next digit (6) of the dividend behind the 45 and repeat the process: 456 / 79

Going ahead to step 8:
The number 79 fits into 456 5 times, leaving a remainder of 61.
Put 5 as the next digit of the answer. 
Result so far: 645895.0
If we take 395 away from 456, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 9:
610 divided by 79 is 7 with a remainder of 57.
Write down 7 as next digit of the result. 
Result so far: 645895.7
If we take 553 away from 610, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 10:
79 goes into 570 7 times with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 645895.77
Subtract 553 from 570 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

In conclusion, the division gives 645895.77 with a balance of 0.017.
