We're dividing 919191 by 4 
We're looking to find how many times 4 goes into 919191.

Moving on to step 1:
When dividing 9 by 4, we get 2 with a remainder of 1.
The next digit of our result is 2. 
Result so far: 2.0
If we take 8 away from 9, we end up with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 4

Advancing to step 2:
When dividing 11 by 4, we get 2 with a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Deduct 8 from 11 and we're left with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 4

On to step 3:
When dividing 39 by 4, we get 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 229.0
The remainder is 3 after subtracting 36 from 39.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 4

Step 4:
31 divided by 4 is 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 2297.0
The remainder is 3 after subtracting 28 from 31.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 4

Let's proceed to step 5:
4 goes into 39 9 times with a remainder of 3.
The next digit of our result is 9. 
Result so far: 22979.0
Subtracting 36 from 39 leaves us with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 4

Let's proceed to step 6:
4 can be fit into 31 7 times, resulting in a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 229797.0
If we subtract 28 from 31, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
30 divided by 4 is 7 with a remainder of 2.
The next digit of our result is 7. 
Result so far: 229797.7
The remainder is 2 after subtracting 28 from 30.
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:
4 goes into 20 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 229797.75
Subtracting 20 from 20 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.

Step 9:
4 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 229797.75
If we subtract 0 from 0, we 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.

Advancing to step 10:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 229797.75
If we subtract 0 from 0, we 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.

The final outcome is 229797.75, with a leftover of 0.0.
