Let's divide 12077421 by 301
We want to figure out the number of times 12077421 can be divided by 301.

Moving on to step 1:
301 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 301

Moving on to step 2:
301 can be fit into 12 0 times, resulting in a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 301

Let's proceed to step 3:
The number 301 fits into 120 0 times, leaving a remainder of 120.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 120 leaves us with 120.
Append the next digit (7) from the dividend to 120 and continue with: 1207 / 301

Moving on to step 4:
If we divide 1207 by 301, we get 4 and a remainder of 3.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 1204 from 1207 to get 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 301

Step 5:
If we divide 37 by 301, we get 0 and a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 40.0
If we subtract 0 from 37, we get 37.
Grab the next digit (4) from the dividend, add it to 37, then carry on: 374 / 301

Going ahead to step 6:
The number 301 fits into 374 1 times, leaving a remainder of 73.
Use 1 as the next digit of our solution. 
Result so far: 401.0
If we take 301 away from 374, we end up with 73.
Append the next digit (2) from the dividend to 73 and continue with: 732 / 301

Advancing to step 7:
732 divided by 301 is 2 with a remainder of 130.
Use 2 as the next digit of our solution. 
Result so far: 4012.0
Subtracting 602 from 732 leaves us with 130.
Grab the next digit (1) from the dividend, add it to 130, then carry on: 1301 / 301

Let's proceed to step 8:
1301 divided by 301 is 4 with a remainder of 97.
Write down 4 as next digit of the result. 
Result so far: 40124.0
Subtracting 1204 from 1301 leaves us with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Moving on to step 9:
If we divide 970 by 301, we get 3 and a remainder of 67.
Put 3 as the next digit of the answer. 
Result so far: 40124.3
Subtracting 903 from 970 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 10:
The number 301 fits into 670 2 times, leaving a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 40124.32
If we subtract 602 from 670, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 11:
The number 301 fits into 680 2 times, leaving a remainder of 78.
Record the quotient 2 as the next digit in the result. 
Result so far: 40124.322
Deduct 602 from 680 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Our division results in 40124.322 with a remaining 0.0078.
