169962 divided by 4 
The aim is to understand the frequency of 4 in 169962.

On to step 1:
1 divided by 4 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 4

Going ahead to step 2:
4 can be fit into 16 4 times, resulting in a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 16 away from 16, we end up with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 4

Advancing to step 3:
4 goes into 9 2 times with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 42.0
If we subtract 8 from 9, we get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 4

On to step 4:
19 divided by 4 is 4 with a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 424.0
If we subtract 16 from 19, we get 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 4

Going ahead to step 5:
If we divide 36 by 4, we get 9 and a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 4249.0
The remainder is 0 after subtracting 36 from 36.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 4

On to step 6:
4 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 42490.0
The remainder is 2 after subtracting 0 from 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
4 goes into 20 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 42490.5
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.

Step 8:
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: 42490.5
Subtract 0 from 0 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.

Going ahead to step 9:
0 divided by 4 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 42490.5
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.

After the division, we end up with 42490.5 and a remainder of 0.0.
