Let's divide 51693666 by 900
We're looking to find how many times 900 goes into 51693666.

On to step 1:
5 divided by 900 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 900

On to step 2:
The number 900 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
Deduct 0 from 51 and we're left with 51.
Take the next digit (6) from the dividend and append it to 51, then repeat: 516 / 900

Moving on to step 3:
516 divided by 900 is 0 with a remainder of 516.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 516 leaves us with 516.
Bring next digit (9) of the dividend behind the 516 and repeat the process: 5169 / 900

Moving on to step 4:
If we divide 5169 by 900, we get 5 and a remainder of 669.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 4500 from 5169, we get 669.
Take the next digit (3) from the dividend and append it to 669, then repeat: 6693 / 900

Step 5:
If we divide 6693 by 900, we get 7 and a remainder of 393.
Use 7 as the next digit of our solution. 
Result so far: 57.0
Deduct 6300 from 6693 and we're left with 393.
Include the next digit (6) from the dividend after 393, then repeat: 3936 / 900

Let's proceed to step 6:
When dividing 3936 by 900, we get 4 with a remainder of 336.
Write down 4 as next digit of the result. 
Result so far: 574.0
If we subtract 3600 from 3936, we get 336.
Bring next digit (6) of the dividend behind the 336 and repeat the process: 3366 / 900

Going ahead to step 7:
3366 divided by 900 is 3 with a remainder of 666.
The number 3 becomes the next digit in our result. 
Result so far: 5743.0
Deduct 2700 from 3366 and we're left with 666.
Take the next digit (6) from the dividend and append it to 666, then repeat: 6666 / 900

Let's proceed to step 8:
900 can be fit into 6666 7 times, resulting in a remainder of 366.
The next digit of our result is 7. 
Result so far: 57437.0
If we take 6300 away from 6666, we end up with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Step 9:
3660 divided by 900 is 4 with a remainder of 60.
Use 4 as the next digit of our solution. 
Result so far: 57437.4
Subtracting 3600 from 3660 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 10:
If we divide 600 by 900, we get 0 and a remainder of 600.
Write down 0 as next digit of the result. 
Result so far: 57437.4
If we take 0 away from 600, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 11:
The number 900 fits into 6000 6 times, leaving a remainder of 600.
Use 6 as the next digit of our solution. 
Result so far: 57437.406
Subtracting 5400 from 6000 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Let's proceed to step 12:
If we divide 6000 by 900, we get 6 and a remainder of 600.
Write down 6 as next digit of the result. 
Result so far: 57437.4066
If we subtract 5400 from 6000, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

In conclusion, the division gives 57437.4066 with a balance of 0.006.
