We're dividing 2553351 by 791 
Let's see how many times 791 fits into 2553351.

On to step 1:
2 divided by 791 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 791

Let's proceed to step 2:
791 can be fit into 25 0 times, resulting in a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Include the next digit (5) from the dividend after 25, then repeat: 255 / 791

On to step 3:
The number 791 fits into 255 0 times, leaving a remainder of 255.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 255, we end up with 255.
Grab the next digit (3) from the dividend, add it to 255, then carry on: 2553 / 791

On to step 4:
791 can be fit into 2553 3 times, resulting in a remainder of 180.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 2373 away from 2553, we end up with 180.
Include the next digit (3) from the dividend after 180, then repeat: 1803 / 791

Let's proceed to step 5:
If we divide 1803 by 791, we get 2 and a remainder of 221.
Put 2 as the next digit of the answer. 
Result so far: 32.0
Subtract 1582 from 1803 to get 221.
Bring next digit (5) of the dividend behind the 221 and repeat the process: 2215 / 791

Let's proceed to step 6:
The number 791 fits into 2215 2 times, leaving a remainder of 633.
Use 2 as the next digit of our solution. 
Result so far: 322.0
Subtracting 1582 from 2215 leaves us with 633.
Bring next digit (1) of the dividend behind the 633 and repeat the process: 6331 / 791

Going ahead to step 7:
791 goes into 6331 8 times with a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 3228.0
Deduct 6328 from 6331 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 8:
30 divided by 791 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 3228.0
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
791 goes into 300 0 times with a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 3228.0
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

After the division, we end up with 3228.0 and a remainder of 0.3.
