Let's divide 56776784 by 621
Let's see how many times 621 fits into 56776784.

Step 1:
The number 621 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 621

Step 2:
When dividing 56 by 621, we get 0 with a remainder of 56.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 56, we get 56.
Take the next digit (7) from the dividend and append it to 56, then repeat: 567 / 621

Going ahead to step 3:
When dividing 567 by 621, we get 0 with a remainder of 567.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 567 to get 567.
Take the next digit (7) from the dividend and append it to 567, then repeat: 5677 / 621

On to step 4:
5677 divided by 621 is 9 with a remainder of 88.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 5589 from 5677 to get 88.
Take the next digit (6) from the dividend and append it to 88, then repeat: 886 / 621

On to step 5:
When dividing 886 by 621, we get 1 with a remainder of 265.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
Subtracting 621 from 886 leaves us with 265.
Grab the next digit (7) from the dividend, add it to 265, then carry on: 2657 / 621

On to step 6:
2657 divided by 621 is 4 with a remainder of 173.
Use 4 as the next digit of our solution. 
Result so far: 914.0
If we subtract 2484 from 2657, we get 173.
Bring next digit (8) of the dividend behind the 173 and repeat the process: 1738 / 621

Going ahead to step 7:
621 can be fit into 1738 2 times, resulting in a remainder of 496.
Use 2 as the next digit of our solution. 
Result so far: 9142.0
If we take 1242 away from 1738, we end up with 496.
Take the next digit (4) from the dividend and append it to 496, then repeat: 4964 / 621

Let's proceed to step 8:
When dividing 4964 by 621, we get 7 with a remainder of 617.
Record the quotient 7 as the next digit in the result. 
Result so far: 91427.0
If we subtract 4347 from 4964, we get 617.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6170, and continue the process.

On to step 9:
621 goes into 6170 9 times with a remainder of 581.
The number 9 becomes the next digit in our result. 
Result so far: 91427.9
The remainder is 581 after subtracting 5589 from 6170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5810, and continue the process.

Let's proceed to step 10:
621 can be fit into 5810 9 times, resulting in a remainder of 221.
Record the quotient 9 as the next digit in the result. 
Result so far: 91427.99
Subtract 5589 from 5810 to get 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

The quotient of the division is 91427.99, and the remainder is 0.221.
