Let's divide 963937 by 4
The aim is to understand the frequency of 4 in 963937.

Going ahead to step 1:
When dividing 9 by 4, we get 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 8 from 9 to get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 4

On to step 2:
4 goes into 16 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 24.0
If we take 16 away from 16, we end up with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 4

Going ahead to step 3:
The number 4 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 240.0
Subtract 0 from 3 to get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 4

On to step 4:
When dividing 39 by 4, we get 9 with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 2409.0
Subtract 36 from 39 to get 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 4

Going ahead to step 5:
33 divided by 4 is 8 with a remainder of 1.
The next digit of our result is 8. 
Result so far: 24098.0
Subtract 32 from 33 to get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 4

Let's proceed to step 6:
If we divide 17 by 4, we get 4 and a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 240984.0
Subtract 16 from 17 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.

Going ahead to step 7:
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: 240984.2
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.

Moving on to step 8:
4 can be fit into 20 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 240984.25
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.

Going ahead to step 9:
4 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 240984.25
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 10:
0 divided by 4 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 240984.25
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 outcome is 240984.25, with a leftover of 0.0.
