Let's divide 80949977 by 4
Let's see how many times 4 fits into 80949977.

Advancing to step 1:
8 divided by 4 is 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 0 after subtracting 8 from 8.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 4

Going ahead to step 2:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we take 0 away from 0, we end up with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 4

Advancing to step 3:
When dividing 9 by 4, we get 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 202.0
The remainder is 1 after subtracting 8 from 9.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 4

On to step 4:
14 divided by 4 is 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 2023.0
The remainder is 2 after subtracting 12 from 14.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 4

Moving on to step 5:
The number 4 fits into 29 7 times, leaving a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 20237.0
If we take 28 away from 29, we end up with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 4

Step 6:
If we divide 19 by 4, we get 4 and a remainder of 3.
The next digit of our result is 4. 
Result so far: 202374.0
Subtract 16 from 19 to get 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 4

Going ahead to step 7:
If we divide 37 by 4, we get 9 and a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 2023749.0
The remainder is 1 after subtracting 36 from 37.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 4

Let's proceed to step 8:
When dividing 17 by 4, we get 4 with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 20237494.0
If we take 16 away from 17, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
The number 4 fits into 10 2 times, leaving a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 20237494.2
Subtract 8 from 10 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.

Advancing to step 10:
4 goes into 20 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 20237494.25
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.

Advancing to step 11:
4 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 20237494.25
Deduct 0 from 0 and we're left 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.

Going ahead to step 12:
When dividing 0 by 4, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 20237494.25
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 result is 20237494.25 with a remainder of 0.0.
