We're dividing 401910 by 4 
The aim is to understand the frequency of 4 in 401910.

Let's proceed to step 1:
4 goes into 4 1 times with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 4 from 4 leaves us with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 4

Moving on to step 2:
When dividing 0 by 4, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 0 leaves us with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 4

Moving on to step 3:
When dividing 1 by 4, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 100.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 4

On to step 4:
4 can be fit into 19 4 times, resulting in a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 1004.0
Subtracting 16 from 19 leaves us with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 4

Let's proceed to step 5:
When dividing 31 by 4, we get 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 10047.0
If we subtract 28 from 31, we get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 4

Let's proceed to step 6:
When dividing 30 by 4, we get 7 with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 100477.0
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.

Step 7:
4 goes into 20 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 100477.5
Subtract 20 from 20 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.

Let's proceed to step 8:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 100477.5
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.

Let's proceed to step 9:
4 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 100477.5
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.

In conclusion, the division gives 100477.5 with a balance of 0.0.
