774643 divided by 57 
Our goal is to divide 774643 by 57.

Step 1:
When dividing 7 by 57, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 57

Advancing to step 2:
57 can be fit into 77 1 times, resulting in a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 57 from 77, we get 20.
Fetch the next digit (4) from the dividend, attach it to 20 and continue: 204 / 57

Moving on to step 3:
If we divide 204 by 57, we get 3 and a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtract 171 from 204 to get 33.
Bring next digit (6) of the dividend behind the 33 and repeat the process: 336 / 57

Moving on to step 4:
If we divide 336 by 57, we get 5 and a remainder of 51.
Record the quotient 5 as the next digit in the result. 
Result so far: 135.0
If we subtract 285 from 336, we get 51.
Include the next digit (4) from the dividend after 51, then repeat: 514 / 57

Let's proceed to step 5:
514 divided by 57 is 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 1359.0
If we take 513 away from 514, we end up with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 57

Let's proceed to step 6:
The number 57 fits into 13 0 times, leaving a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 13590.0
If we subtract 0 from 13, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
The number 57 fits into 130 2 times, leaving a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 13590.2
If we subtract 114 from 130, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 8:
When dividing 160 by 57, we get 2 with a remainder of 46.
The next digit of our result is 2. 
Result so far: 13590.22
If we subtract 114 from 160, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final outcome is 13590.22, with a leftover of 0.046.
