We're dividing 4278074 by 484 
We're looking to find how many times 484 goes into 4278074.

On to step 1:
484 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 484

Moving on to step 2:
If we divide 42 by 484, we get 0 and a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Grab the next digit (7) from the dividend, add it to 42, then carry on: 427 / 484

Step 3:
When dividing 427 by 484, we get 0 with a remainder of 427.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 427 after subtracting 0 from 427.
Include the next digit (8) from the dividend after 427, then repeat: 4278 / 484

Let's proceed to step 4:
When dividing 4278 by 484, we get 8 with a remainder of 406.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 3872 from 4278, we get 406.
Grab the next digit (0) from the dividend, add it to 406, then carry on: 4060 / 484

Step 5:
484 can be fit into 4060 8 times, resulting in a remainder of 188.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
Subtracting 3872 from 4060 leaves us with 188.
Bring next digit (7) of the dividend behind the 188 and repeat the process: 1887 / 484

Let's proceed to step 6:
484 goes into 1887 3 times with a remainder of 435.
The number 3 becomes the next digit in our result. 
Result so far: 883.0
Subtracting 1452 from 1887 leaves us with 435.
Fetch the next digit (4) from the dividend, attach it to 435 and continue: 4354 / 484

Advancing to step 7:
When dividing 4354 by 484, we get 8 with a remainder of 482.
The number 8 becomes the next digit in our result. 
Result so far: 8838.0
Subtract 3872 from 4354 to get 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Step 8:
If we divide 4820 by 484, we get 9 and a remainder of 464.
Use 9 as the next digit of our solution. 
Result so far: 8838.9
The remainder is 464 after subtracting 4356 from 4820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Moving on to step 9:
484 can be fit into 4640 9 times, resulting in a remainder of 284.
Put 9 as the next digit of the answer. 
Result so far: 8838.99
If we take 4356 away from 4640, we end up with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

The final outcome is 8838.99, with a leftover of 0.284.
