Let's divide 51193419 by 900
Let's see how many times 900 fits into 51193419.

Moving on to step 1:
The number 900 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 900

Step 2:
When dividing 51 by 900, we get 0 with a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Include the next digit (1) from the dividend after 51, then repeat: 511 / 900

Moving on to step 3:
900 can be fit into 511 0 times, resulting in a remainder of 511.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 511 leaves us with 511.
Append the next digit (9) from the dividend to 511 and continue with: 5119 / 900

Going ahead to step 4:
The number 900 fits into 5119 5 times, leaving a remainder of 619.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 619 after subtracting 4500 from 5119.
Bring next digit (3) of the dividend behind the 619 and repeat the process: 6193 / 900

Going ahead to step 5:
If we divide 6193 by 900, we get 6 and a remainder of 793.
The next digit of our result is 6. 
Result so far: 56.0
Subtract 5400 from 6193 to get 793.
Include the next digit (4) from the dividend after 793, then repeat: 7934 / 900

Step 6:
7934 divided by 900 is 8 with a remainder of 734.
Put 8 as the next digit of the answer. 
Result so far: 568.0
Subtract 7200 from 7934 to get 734.
Fetch the next digit (1) from the dividend, attach it to 734 and continue: 7341 / 900

Advancing to step 7:
If we divide 7341 by 900, we get 8 and a remainder of 141.
The number 8 becomes the next digit in our result. 
Result so far: 5688.0
If we subtract 7200 from 7341, we get 141.
Bring next digit (9) of the dividend behind the 141 and repeat the process: 1419 / 900

Let's proceed to step 8:
900 goes into 1419 1 times with a remainder of 519.
Use 1 as the next digit of our solution. 
Result so far: 56881.0
Deduct 900 from 1419 and we're left with 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

Going ahead to step 9:
The number 900 fits into 5190 5 times, leaving a remainder of 690.
The number 5 becomes the next digit in our result. 
Result so far: 56881.5
If we take 4500 away from 5190, we end up with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Advancing to step 10:
If we divide 6900 by 900, we get 7 and a remainder of 600.
The number 7 becomes the next digit in our result. 
Result so far: 56881.57
If we subtract 6300 from 6900, 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.

On to step 11:
The number 900 fits into 6000 6 times, leaving a remainder of 600.
The next digit of our result is 6. 
Result so far: 56881.576
If we take 5400 away from 6000, 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.

On to step 12:
If we divide 6000 by 900, we get 6 and a remainder of 600.
The number 6 becomes the next digit in our result. 
Result so far: 56881.5766
Deduct 5400 from 6000 and we're left 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.

The final outcome is 56881.5766, with a leftover of 0.006.
