We're dividing 4272012 by 578 
Let's see how many times 578 fits into 4272012.

Step 1:
When dividing 4 by 578, we get 0 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.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 578

On to step 2:
The number 578 fits into 42 0 times, leaving a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Take the next digit (7) from the dividend and append it to 42, then repeat: 427 / 578

Step 3:
If we divide 427 by 578, we get 0 and a remainder of 427.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 427, we end up with 427.
Grab the next digit (2) from the dividend, add it to 427, then carry on: 4272 / 578

Step 4:
4272 divided by 578 is 7 with a remainder of 226.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 4046 from 4272 to get 226.
Fetch the next digit (0) from the dividend, attach it to 226 and continue: 2260 / 578

Step 5:
2260 divided by 578 is 3 with a remainder of 526.
The next digit of our result is 3. 
Result so far: 73.0
If we subtract 1734 from 2260, we get 526.
Include the next digit (1) from the dividend after 526, then repeat: 5261 / 578

Moving on to step 6:
5261 divided by 578 is 9 with a remainder of 59.
Put 9 as the next digit of the answer. 
Result so far: 739.0
Deduct 5202 from 5261 and we're left with 59.
Bring next digit (2) of the dividend behind the 59 and repeat the process: 592 / 578

Going ahead to step 7:
When dividing 592 by 578, we get 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 7391.0
Subtracting 578 from 592 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
If we divide 140 by 578, we get 0 and a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 7391.0
The remainder is 140 after subtracting 0 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 9:
578 can be fit into 1400 2 times, resulting in a remainder of 244.
Record the quotient 2 as the next digit in the result. 
Result so far: 7391.02
Deduct 1156 from 1400 and we're left with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Advancing to step 10:
When dividing 2440 by 578, we get 4 with a remainder of 128.
The number 4 becomes the next digit in our result. 
Result so far: 7391.024
Deduct 2312 from 2440 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 11:
The number 578 fits into 1280 2 times, leaving a remainder of 124.
Write down 2 as next digit of the result. 
Result so far: 7391.0242
Deduct 1156 from 1280 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Let's proceed to step 12:
1240 divided by 578 is 2 with a remainder of 84.
Record the quotient 2 as the next digit in the result. 
Result so far: 7391.02422
If we subtract 1156 from 1240, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The final result is 7391.02422 with a remainder of 8.4e-05.
