We look at the division of 337008 by 90 
The aim is to understand the frequency of 90 in 337008.

Moving on to step 1:
If we divide 3 by 90, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 90

Going ahead to step 2:
90 goes into 33 0 times with a remainder of 33.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 33 leaves us with 33.
Fetch the next digit (7) from the dividend, attach it to 33 and continue: 337 / 90

Moving on to step 3:
When dividing 337 by 90, we get 3 with a remainder of 67.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 270 away from 337, we end up with 67.
Grab the next digit (0) from the dividend, add it to 67, then carry on: 670 / 90

Let's proceed to step 4:
When dividing 670 by 90, we get 7 with a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 37.0
Subtracting 630 from 670 leaves us with 40.
Include the next digit (0) from the dividend after 40, then repeat: 400 / 90

Advancing to step 5:
If we divide 400 by 90, we get 4 and a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 374.0
Subtract 360 from 400 to get 40.
Include the next digit (8) from the dividend after 40, then repeat: 408 / 90

On to step 6:
408 divided by 90 is 4 with a remainder of 48.
The next digit of our result is 4. 
Result so far: 3744.0
If we subtract 360 from 408, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 7:
If we divide 480 by 90, we get 5 and a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 3744.5
Deduct 450 from 480 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
If we divide 300 by 90, we get 3 and a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 3744.53
If we take 270 away from 300, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
The number 90 fits into 300 3 times, leaving a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 3744.533
Subtract 270 from 300 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

In conclusion, the division gives 3744.533 with a balance of 0.003.
