We divide 654198 by 4
The aim is to understand the frequency of 4 in 654198.

Let's proceed to step 1:
The number 4 fits into 6 1 times, leaving a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 4 from 6 and we're left with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 4

On to step 2:
The number 4 fits into 25 6 times, leaving a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 16.0
The remainder is 1 after subtracting 24 from 25.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 4

Let's proceed to step 3:
4 goes into 14 3 times with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 163.0
Subtract 12 from 14 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 4

Step 4:
If we divide 21 by 4, we get 5 and a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 1635.0
The remainder is 1 after subtracting 20 from 21.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 4

Let's proceed to step 5:
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: 16354.0
Subtracting 16 from 19 leaves us with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 4

On to step 6:
38 divided by 4 is 9 with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 163549.0
Subtract 36 from 38 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 7:
If we divide 20 by 4, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 163549.5
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.

On to step 8:
If we divide 0 by 4, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 163549.5
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.

Advancing to step 9:
4 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 163549.5
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.

After the division, we end up with 163549.5 and a remainder of 0.0.
