We're dividing 353758 by 3 
The aim is to understand the frequency of 3 in 353758.

Moving on to step 1:
If we divide 3 by 3, we get 1 and a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 3 from 3, we get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 3

On to step 2:
3 goes into 5 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 11.0
If we take 3 away from 5, we end up with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 3

Advancing to step 3:
If we divide 23 by 3, we get 7 and a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 117.0
If we subtract 21 from 23, we get 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 3

Advancing to step 4:
3 can be fit into 27 9 times, resulting in a remainder of 0.
The next digit of our result is 9. 
Result so far: 1179.0
Subtracting 27 from 27 leaves us with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 3

Let's proceed to step 5:
3 goes into 5 1 times with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 11791.0
If we take 3 away from 5, we end up with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 3

On to step 6:
28 divided by 3 is 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 117919.0
Subtract 27 from 28 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.

Moving on to step 7:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 117919.3
Subtracting 9 from 10 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 8:
3 goes into 10 3 times with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 117919.33
Subtract 9 from 10 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.

The quotient of the division is 117919.33, and the remainder is 0.001.
