We look at the division of 514091 by 4 
Let's see how many times 4 fits into 514091.

On to step 1:
If we divide 5 by 4, we get 1 and a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 4 from 5 leaves us with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 4

Going ahead to step 2:
4 can be fit into 11 2 times, resulting in a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 8 from 11 leaves us with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 4

Advancing to step 3:
4 goes into 34 8 times with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 128.0
If we subtract 32 from 34, we get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 4

On to step 4:
4 goes into 20 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 1285.0
The remainder is 0 after subtracting 20 from 20.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 4

On to step 5:
If we divide 9 by 4, we get 2 and a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 12852.0
Deduct 8 from 9 and we're left with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 4

Step 6:
When dividing 11 by 4, we get 2 with a remainder of 3.
The next digit of our result is 2. 
Result so far: 128522.0
Subtracting 8 from 11 leaves us 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 7:
If we divide 30 by 4, we get 7 and a remainder of 2.
The next digit of our result is 7. 
Result so far: 128522.7
Subtract 28 from 30 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
If we divide 20 by 4, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 128522.75
The remainder is 0 after subtracting 20 from 20.
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 9:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 128522.75
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
When dividing 0 by 4, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 128522.75
Subtracting 0 from 0 leaves us 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.

The final result is 128522.75 with a remainder of 0.0.
