Let's divide 76586903 by 4
Our goal is to divide 76586903 by 4.

On to step 1:
When dividing 7 by 4, we get 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 4 away from 7, we end up with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 4

Advancing to step 2:
The number 4 fits into 36 9 times, leaving a remainder of 0.
The next digit of our result is 9. 
Result so far: 19.0
Deduct 36 from 36 and we're left with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 4

Advancing to step 3:
The number 4 fits into 5 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 191.0
Subtract 4 from 5 to get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 4

Let's proceed to step 4:
4 can be fit into 18 4 times, resulting in a remainder of 2.
The next digit of our result is 4. 
Result so far: 1914.0
Subtract 16 from 18 to get 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 4

Step 5:
If we divide 26 by 4, we get 6 and a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 19146.0
Subtracting 24 from 26 leaves us with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 4

Step 6:
29 divided by 4 is 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 191467.0
If we subtract 28 from 29, we get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 4

Advancing to step 7:
4 can be fit into 10 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 1914672.0
The remainder is 2 after subtracting 8 from 10.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 4

Step 8:
4 can be fit into 23 5 times, resulting in a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 19146725.0
Subtract 20 from 23 to 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.

Let's proceed to step 9:
30 divided by 4 is 7 with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 19146725.7
Deduct 28 from 30 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
The number 4 fits into 20 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 19146725.75
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.

On to step 11:
4 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 19146725.75
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.

Step 12:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 19146725.75
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.

After the division, we end up with 19146725.75 and a remainder of 0.0.
