We look at the division of 51137126 by 900 
We're looking to find how many times 900 goes into 51137126.

Step 1:
When dividing 5 by 900, we get 0 with 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.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 900

On to step 2:
51 divided by 900 is 0 with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Fetch the next digit (1) from the dividend, attach it to 51 and continue: 511 / 900

On to step 3:
When dividing 511 by 900, we get 0 with a remainder of 511.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 511, we end up with 511.
Include the next digit (3) from the dividend after 511, then repeat: 5113 / 900

Let's proceed to step 4:
When dividing 5113 by 900, we get 5 with a remainder of 613.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 4500 from 5113 leaves us with 613.
Fetch the next digit (7) from the dividend, attach it to 613 and continue: 6137 / 900

Going ahead to step 5:
900 goes into 6137 6 times with a remainder of 737.
Use 6 as the next digit of our solution. 
Result so far: 56.0
The remainder is 737 after subtracting 5400 from 6137.
Take the next digit (1) from the dividend and append it to 737, then repeat: 7371 / 900

Let's proceed to step 6:
900 can be fit into 7371 8 times, resulting in a remainder of 171.
The next digit of our result is 8. 
Result so far: 568.0
If we take 7200 away from 7371, we end up with 171.
Grab the next digit (2) from the dividend, add it to 171, then carry on: 1712 / 900

Step 7:
1712 divided by 900 is 1 with a remainder of 812.
Use 1 as the next digit of our solution. 
Result so far: 5681.0
If we take 900 away from 1712, we end up with 812.
Fetch the next digit (6) from the dividend, attach it to 812 and continue: 8126 / 900

Moving on to step 8:
If we divide 8126 by 900, we get 9 and a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 56819.0
The remainder is 26 after subtracting 8100 from 8126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 9:
900 can be fit into 260 0 times, resulting in a remainder of 260.
Write down 0 as next digit of the result. 
Result so far: 56819.0
The remainder is 260 after subtracting 0 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 10:
If we divide 2600 by 900, we get 2 and a remainder of 800.
Put 2 as the next digit of the answer. 
Result so far: 56819.02
Subtract 1800 from 2600 to get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Moving on to step 11:
If we divide 8000 by 900, we get 8 and a remainder of 800.
Use 8 as the next digit of our solution. 
Result so far: 56819.028
Deduct 7200 from 8000 and we're left with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Step 12:
If we divide 8000 by 900, we get 8 and a remainder of 800.
Record the quotient 8 as the next digit in the result. 
Result so far: 56819.0288
Deduct 7200 from 8000 and we're left with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Our division results in 56819.0288 with a remaining 0.008.
