49393471 divided by 4 
The aim is to understand the frequency of 4 in 49393471.

On to step 1:
When dividing 4 by 4, we get 1 with a remainder of 0.
The next digit of our result is 1. 
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

Moving on to step 2:
9 divided by 4 is 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 8 from 9 to get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 4

Step 3:
4 can be fit into 13 3 times, resulting in a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 123.0
The remainder is 1 after subtracting 12 from 13.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 4

Let's proceed to step 4:
When dividing 19 by 4, we get 4 with a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 1234.0
Subtract 16 from 19 to get 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 4

Advancing to step 5:
4 can be fit into 33 8 times, resulting in a remainder of 1.
The next digit of our result is 8. 
Result so far: 12348.0
If we subtract 32 from 33, we get 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 4

Moving on to step 6:
4 can be fit into 14 3 times, resulting in a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 123483.0
Subtract 12 from 14 to get 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 4

Going ahead to step 7:
When dividing 27 by 4, we get 6 with a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 1234836.0
If we take 24 away from 27, we end up with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 4

Step 8:
If we divide 31 by 4, we get 7 and a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 12348367.0
Deduct 28 from 31 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 9:
If we divide 30 by 4, we get 7 and a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 12348367.7
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.

Advancing 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: 12348367.75
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.

Let's proceed to step 11:
The number 4 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12348367.75
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:
4 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 12348367.75
Subtract 0 from 0 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.

After the division, we end up with 12348367.75 and a remainder of 0.0.
