Let's divide 53126370 by 518
We want to figure out the number of times 53126370 can be divided by 518.

Let's proceed to step 1:
518 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 518

On to step 2:
518 goes into 53 0 times with a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Fetch the next digit (1) from the dividend, attach it to 53 and continue: 531 / 518

On to step 3:
When dividing 531 by 518, we get 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 518 from 531, we get 13.
Append the next digit (2) from the dividend to 13 and continue with: 132 / 518

Step 4:
132 divided by 518 is 0 with a remainder of 132.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 132 to get 132.
Grab the next digit (6) from the dividend, add it to 132, then carry on: 1326 / 518

On to step 5:
1326 divided by 518 is 2 with a remainder of 290.
The next digit of our result is 2. 
Result so far: 102.0
Deduct 1036 from 1326 and we're left with 290.
Bring next digit (3) of the dividend behind the 290 and repeat the process: 2903 / 518

Step 6:
518 can be fit into 2903 5 times, resulting in a remainder of 313.
Record the quotient 5 as the next digit in the result. 
Result so far: 1025.0
If we take 2590 away from 2903, we end up with 313.
Take the next digit (7) from the dividend and append it to 313, then repeat: 3137 / 518

On to step 7:
3137 divided by 518 is 6 with a remainder of 29.
The next digit of our result is 6. 
Result so far: 10256.0
Subtract 3108 from 3137 to get 29.
Append the next digit (0) from the dividend to 29 and continue with: 290 / 518

Moving on to step 8:
518 goes into 290 0 times with a remainder of 290.
The number 0 becomes the next digit in our result. 
Result so far: 102560.0
Subtract 0 from 290 to get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

On to step 9:
518 goes into 2900 5 times with a remainder of 310.
Record the quotient 5 as the next digit in the result. 
Result so far: 102560.5
If we subtract 2590 from 2900, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 10:
The number 518 fits into 3100 5 times, leaving a remainder of 510.
Put 5 as the next digit of the answer. 
Result so far: 102560.55
If we subtract 2590 from 3100, we get 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

After the division, we end up with 102560.55 and a remainder of 0.51.
