We look at the division of 696331 by 4 
The aim is to understand the frequency of 4 in 696331.

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.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 4

Advancing to step 2:
29 divided by 4 is 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we subtract 28 from 29, we get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 4

Going ahead to step 3:
When dividing 16 by 4, we get 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 174.0
Subtracting 16 from 16 leaves us with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 4

On to step 4:
If we divide 3 by 4, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 1740.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 4

Going ahead to step 5:
4 can be fit into 33 8 times, resulting in a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 17408.0
If we subtract 32 from 33, we get 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 4

Going ahead to step 6:
4 can be fit into 11 2 times, resulting in a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 174082.0
Subtract 8 from 11 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
4 can be fit into 30 7 times, resulting in a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 174082.7
Subtracting 28 from 30 leaves us with 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 8:
When dividing 20 by 4, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 174082.75
If we take 20 away from 20, 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.

Let's proceed to step 9:
0 divided by 4 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 174082.75
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.

On to step 10:
0 divided by 4 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 174082.75
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.

The quotient of the division is 174082.75, and the remainder is 0.0.
