We look at the division of 51396393 by 522 
We want to figure out the number of times 51396393 can be divided by 522.

Let's proceed to step 1:
If we divide 5 by 522, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 522

Let's proceed to step 2:
The number 522 fits into 51 0 times, leaving a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Include the next digit (3) from the dividend after 51, then repeat: 513 / 522

Moving on to step 3:
When dividing 513 by 522, we get 0 with a remainder of 513.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 513 leaves us with 513.
Grab the next digit (9) from the dividend, add it to 513, then carry on: 5139 / 522

Let's proceed to step 4:
The number 522 fits into 5139 9 times, leaving a remainder of 441.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 441 after subtracting 4698 from 5139.
Include the next digit (6) from the dividend after 441, then repeat: 4416 / 522

Advancing to step 5:
522 can be fit into 4416 8 times, resulting in a remainder of 240.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
Subtract 4176 from 4416 to get 240.
Append the next digit (3) from the dividend to 240 and continue with: 2403 / 522

Advancing to step 6:
The number 522 fits into 2403 4 times, leaving a remainder of 315.
Put 4 as the next digit of the answer. 
Result so far: 984.0
If we take 2088 away from 2403, we end up with 315.
Include the next digit (9) from the dividend after 315, then repeat: 3159 / 522

Let's proceed to step 7:
The number 522 fits into 3159 6 times, leaving a remainder of 27.
The number 6 becomes the next digit in our result. 
Result so far: 9846.0
If we subtract 3132 from 3159, we get 27.
Bring next digit (3) of the dividend behind the 27 and repeat the process: 273 / 522

Advancing to step 8:
522 goes into 273 0 times with a remainder of 273.
The next digit of our result is 0. 
Result so far: 98460.0
Subtracting 0 from 273 leaves us with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

On to step 9:
522 can be fit into 2730 5 times, resulting in a remainder of 120.
Record the quotient 5 as the next digit in the result. 
Result so far: 98460.5
If we subtract 2610 from 2730, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 10:
522 can be fit into 1200 2 times, resulting in a remainder of 156.
Put 2 as the next digit of the answer. 
Result so far: 98460.52
The remainder is 156 after subtracting 1044 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Advancing to step 11:
1560 divided by 522 is 2 with a remainder of 516.
Record the quotient 2 as the next digit in the result. 
Result so far: 98460.522
The remainder is 516 after subtracting 1044 from 1560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

In conclusion, the division gives 98460.522 with a balance of 0.0516.
