Let's divide 491251 by 4
Our goal is to divide 491251 by 4.

Let's proceed to step 1:
If we divide 4 by 4, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 4 from 4 leaves us with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 4

On to step 2:
If we divide 9 by 4, we get 2 and a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 1 after subtracting 8 from 9.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 4

Going ahead to step 3:
4 can be fit into 11 2 times, resulting in a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 122.0
Subtract 8 from 11 to get 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 4

Moving on to step 4:
The number 4 fits into 32 8 times, leaving a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 1228.0
Subtracting 32 from 32 leaves us with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 4

Moving on to step 5:
4 goes into 5 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 12281.0
If we take 4 away from 5, 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 6:
11 divided by 4 is 2 with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 122812.0
The remainder is 3 after subtracting 8 from 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
The number 4 fits into 30 7 times, leaving a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 122812.7
If we subtract 28 from 30, we 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:
20 divided by 4 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 122812.75
Subtract 20 from 20 to 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.

On to step 9:
If we divide 0 by 4, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 122812.75
If we take 0 away from 0, we end up 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.

Let's proceed to step 10:
When dividing 0 by 4, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 122812.75
If we take 0 away from 0, we end up 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 outcome is 122812.75, with a leftover of 0.0.
