We're dividing 342005 by 90 
The aim is to understand the frequency of 90 in 342005.

Moving on to step 1:
90 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 90

Step 2:
The number 90 fits into 34 0 times, leaving a remainder of 34.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 34, we end up with 34.
Append the next digit (2) from the dividend to 34 and continue with: 342 / 90

Step 3:
When dividing 342 by 90, we get 3 with a remainder of 72.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 270 from 342, we get 72.
Append the next digit (0) from the dividend to 72 and continue with: 720 / 90

Step 4:
90 goes into 720 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 38.0
The remainder is 0 after subtracting 720 from 720.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 90

On to step 5:
If we divide 0 by 90, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 380.0
Deduct 0 from 0 and we're left with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 90

On to step 6:
90 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 3800.0
The remainder is 5 after subtracting 0 from 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
If we divide 50 by 90, we get 0 and a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 3800.0
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 8:
90 goes into 500 5 times with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 3800.05
If we take 450 away from 500, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
If we divide 500 by 90, we get 5 and a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 3800.055
If we take 450 away from 500, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The quotient of the division is 3800.055, and the remainder is 0.005.
