We look at the division of 2556999 by 120 
Our goal is to divide 2556999 by 120.

Advancing to step 1:
120 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 120

On to step 2:
When dividing 25 by 120, we get 0 with a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Bring next digit (5) of the dividend behind the 25 and repeat the process: 255 / 120

Going ahead to step 3:
120 can be fit into 255 2 times, resulting in a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 240 from 255, we get 15.
Append the next digit (6) from the dividend to 15 and continue with: 156 / 120

Let's proceed to step 4:
156 divided by 120 is 1 with a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtracting 120 from 156 leaves us with 36.
Grab the next digit (9) from the dividend, add it to 36, then carry on: 369 / 120

Let's proceed to step 5:
If we divide 369 by 120, we get 3 and a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 213.0
If we subtract 360 from 369, we get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 120

Advancing to step 6:
120 can be fit into 99 0 times, resulting in a remainder of 99.
The next digit of our result is 0. 
Result so far: 2130.0
Deduct 0 from 99 and we're left with 99.
Append the next digit (9) from the dividend to 99 and continue with: 999 / 120

Moving on to step 7:
The number 120 fits into 999 8 times, leaving a remainder of 39.
Use 8 as the next digit of our solution. 
Result so far: 21308.0
If we take 960 away from 999, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 8:
390 divided by 120 is 3 with a remainder of 30.
The next digit of our result is 3. 
Result so far: 21308.3
The remainder is 30 after subtracting 360 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
When dividing 300 by 120, we get 2 with a remainder of 60.
The next digit of our result is 2. 
Result so far: 21308.32
Subtract 240 from 300 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 10:
When dividing 600 by 120, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 21308.325
Deduct 600 from 600 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
120 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 21308.325
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 12:
120 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 21308.325
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 21308.325 with a remaining 0.0.
