We divide 63570153 by 4
The aim is to understand the frequency of 4 in 63570153.

Let's proceed to step 1:
The number 4 fits into 6 1 times, leaving a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 2 after subtracting 4 from 6.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 4

Moving on to step 2:
4 goes into 23 5 times with a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtract 20 from 23 to get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 4

Let's proceed to step 3:
If we divide 35 by 4, we get 8 and a remainder of 3.
The next digit of our result is 8. 
Result so far: 158.0
If we take 32 away from 35, we end up with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 4

Moving on to step 4:
4 can be fit into 37 9 times, resulting in a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 1589.0
If we take 36 away from 37, we end up with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 4

Advancing to step 5:
10 divided by 4 is 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 15892.0
If we take 8 away from 10, we end up with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 4

Let's proceed to step 6:
When dividing 21 by 4, we get 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 158925.0
If we take 20 away from 21, we end up with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 4

Moving on to step 7:
The number 4 fits into 15 3 times, leaving a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 1589253.0
Subtract 12 from 15 to get 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 4

Step 8:
When dividing 33 by 4, we get 8 with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 15892538.0
Subtract 32 from 33 to 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:
The number 4 fits into 10 2 times, leaving a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 15892538.2
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.

Advancing to step 10:
When dividing 20 by 4, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 15892538.25
Deduct 20 from 20 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.

Let's proceed to step 11:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 15892538.25
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.

Going ahead to step 12:
If we divide 0 by 4, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15892538.25
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.

The quotient of the division is 15892538.25, and the remainder is 0.0.
