We divide 51511230 by 79
Let's see how many times 79 fits into 51511230.

Advancing to step 1:
79 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 79

Advancing to step 2:
79 can be fit into 51 0 times, resulting in a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Bring next digit (5) of the dividend behind the 51 and repeat the process: 515 / 79

Moving on to step 3:
When dividing 515 by 79, we get 6 with a remainder of 41.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 474 from 515, we get 41.
Take the next digit (1) from the dividend and append it to 41, then repeat: 411 / 79

Going ahead to step 4:
The number 79 fits into 411 5 times, leaving a remainder of 16.
Record the quotient 5 as the next digit in the result. 
Result so far: 65.0
If we take 395 away from 411, we end up with 16.
Include the next digit (1) from the dividend after 16, then repeat: 161 / 79

On to step 5:
79 goes into 161 2 times with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 652.0
Subtract 158 from 161 to get 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 79

Advancing to step 6:
The number 79 fits into 32 0 times, leaving a remainder of 32.
Write down 0 as next digit of the result. 
Result so far: 6520.0
Subtract 0 from 32 to get 32.
Bring next digit (3) of the dividend behind the 32 and repeat the process: 323 / 79

Let's proceed to step 7:
79 can be fit into 323 4 times, resulting in a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 65204.0
If we take 316 away from 323, we end up with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 79

Moving on to step 8:
79 goes into 70 0 times with a remainder of 70.
The next digit of our result is 0. 
Result so far: 652040.0
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 9:
700 divided by 79 is 8 with a remainder of 68.
Use 8 as the next digit of our solution. 
Result so far: 652040.8
If we subtract 632 from 700, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 10:
680 divided by 79 is 8 with a remainder of 48.
The next digit of our result is 8. 
Result so far: 652040.88
Subtract 632 from 680 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 652040.88, with a leftover of 0.048.
