51556450 ÷ 99 
We want to figure out the number of times 51556450 can be divided by 99.

Moving on to step 1:
If we divide 5 by 99, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 99

Step 2:
When dividing 51 by 99, we get 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Bring next digit (5) of the dividend behind the 51 and repeat the process: 515 / 99

Advancing to step 3:
When dividing 515 by 99, we get 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 495 away from 515, we end up with 20.
Take the next digit (5) from the dividend and append it to 20, then repeat: 205 / 99

Step 4:
When dividing 205 by 99, we get 2 with a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
If we subtract 198 from 205, we get 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 99

On to step 5:
76 divided by 99 is 0 with a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 520.0
Subtracting 0 from 76 leaves us with 76.
Fetch the next digit (4) from the dividend, attach it to 76 and continue: 764 / 99

Moving on to step 6:
If we divide 764 by 99, we get 7 and a remainder of 71.
Record the quotient 7 as the next digit in the result. 
Result so far: 5207.0
The remainder is 71 after subtracting 693 from 764.
Take the next digit (5) from the dividend and append it to 71, then repeat: 715 / 99

Let's proceed to step 7:
When dividing 715 by 99, we get 7 with a remainder of 22.
The next digit of our result is 7. 
Result so far: 52077.0
Subtracting 693 from 715 leaves us with 22.
Append the next digit (0) from the dividend to 22 and continue with: 220 / 99

Moving on to step 8:
When dividing 220 by 99, we get 2 with a remainder of 22.
The next digit of our result is 2. 
Result so far: 520772.0
If we subtract 198 from 220, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
99 can be fit into 220 2 times, resulting in a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 520772.2
If we subtract 198 from 220, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 10:
When dividing 220 by 99, we get 2 with a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 520772.22
Deduct 198 from 220 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 520772.22 with a remainder of 0.022.
