Let's divide 51185289 by 505
We're looking to find how many times 505 goes into 51185289.

On to step 1:
If we divide 5 by 505, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 505

Step 2:
505 goes into 51 0 times 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.
Fetch the next digit (1) from the dividend, attach it to 51 and continue: 511 / 505

Let's proceed to step 3:
If we divide 511 by 505, we get 1 and a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 6 after subtracting 505 from 511.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 505

Going ahead to step 4:
When dividing 68 by 505, we get 0 with a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 68 leaves us with 68.
Grab the next digit (5) from the dividend, add it to 68, then carry on: 685 / 505

Let's proceed to step 5:
If we divide 685 by 505, we get 1 and a remainder of 180.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
If we take 505 away from 685, we end up with 180.
Grab the next digit (2) from the dividend, add it to 180, then carry on: 1802 / 505

Advancing to step 6:
1802 divided by 505 is 3 with a remainder of 287.
Use 3 as the next digit of our solution. 
Result so far: 1013.0
Subtract 1515 from 1802 to get 287.
Append the next digit (8) from the dividend to 287 and continue with: 2878 / 505

Step 7:
When dividing 2878 by 505, we get 5 with a remainder of 353.
The number 5 becomes the next digit in our result. 
Result so far: 10135.0
Subtracting 2525 from 2878 leaves us with 353.
Grab the next digit (9) from the dividend, add it to 353, then carry on: 3539 / 505

Going ahead to step 8:
3539 divided by 505 is 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 101357.0
Subtracting 3535 from 3539 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
40 divided by 505 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 101357.0
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
If we divide 400 by 505, we get 0 and a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 101357.0
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The quotient of the division is 101357.0, and the remainder is 0.4.
