556450 ÷ 77 
We want to figure out the number of times 556450 can be divided by 77.

Step 1:
When dividing 5 by 77, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 77

Advancing to step 2:
77 can be fit into 55 0 times, resulting in a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Take the next digit (6) from the dividend and append it to 55, then repeat: 556 / 77

Step 3:
77 can be fit into 556 7 times, resulting in a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 539 from 556 and we're left with 17.
Include the next digit (4) from the dividend after 17, then repeat: 174 / 77

Let's proceed to step 4:
174 divided by 77 is 2 with a remainder of 20.
The next digit of our result is 2. 
Result so far: 72.0
The remainder is 20 after subtracting 154 from 174.
Bring next digit (5) of the dividend behind the 20 and repeat the process: 205 / 77

Moving on to step 5:
If we divide 205 by 77, we get 2 and a remainder of 51.
The next digit of our result is 2. 
Result so far: 722.0
If we take 154 away from 205, we end up with 51.
Fetch the next digit (0) from the dividend, attach it to 51 and continue: 510 / 77

Going ahead to step 6:
When dividing 510 by 77, we get 6 with a remainder of 48.
The next digit of our result is 6. 
Result so far: 7226.0
Subtracting 462 from 510 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 7:
480 divided by 77 is 6 with a remainder of 18.
The next digit of our result is 6. 
Result so far: 7226.6
Subtracting 462 from 480 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
77 can be fit into 180 2 times, resulting in a remainder of 26.
The next digit of our result is 2. 
Result so far: 7226.62
Deduct 154 from 180 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 9:
The number 77 fits into 260 3 times, leaving a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 7226.623
If we subtract 231 from 260, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 10:
The number 77 fits into 290 3 times, leaving a remainder of 59.
The number 3 becomes the next digit in our result. 
Result so far: 7226.6233
If we take 231 away from 290, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Our division results in 7226.6233 with a remaining 0.00059.
