49517577 ÷ 4 
We want to figure out the number of times 49517577 can be divided by 4.

Moving on to step 1:
4 goes into 4 1 times with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 4 from 4 and we're left with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 4

On to step 2:
4 can be fit into 9 2 times, resulting in a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 1 after subtracting 8 from 9.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 4

Advancing to step 3:
4 goes into 15 3 times with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 123.0
Subtract 12 from 15 to get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 4

Moving on to step 4:
4 goes into 31 7 times with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 1237.0
If we take 28 away from 31, we end up with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 4

Advancing to step 5:
4 goes into 37 9 times with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 12379.0
If we subtract 36 from 37, we get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 4

Moving on to step 6:
When dividing 15 by 4, we get 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 123793.0
The remainder is 3 after subtracting 12 from 15.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 4

Advancing to step 7:
When dividing 37 by 4, we get 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 1237939.0
Deduct 36 from 37 and we're left with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 4

Let's proceed to step 8:
17 divided by 4 is 4 with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 12379394.0
If we subtract 16 from 17, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 9:
When dividing 10 by 4, we get 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 12379394.2
If we subtract 8 from 10, 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.

Going ahead to step 10:
4 can be fit into 20 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 12379394.25
If we subtract 20 from 20, 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 11:
When dividing 0 by 4, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12379394.25
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 12:
If we divide 0 by 4, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12379394.25
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.

After the division, we end up with 12379394.25 and a remainder of 0.0.
