174914 divided by 90 
The aim is to understand the frequency of 90 in 174914.

Advancing to step 1:
When dividing 1 by 90, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 90

Let's proceed to step 2:
17 divided by 90 is 0 with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 90

Going ahead to step 3:
The number 90 fits into 174 1 times, leaving a remainder of 84.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 90 from 174 to get 84.
Bring next digit (9) of the dividend behind the 84 and repeat the process: 849 / 90

Moving on to step 4:
90 goes into 849 9 times with a remainder of 39.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Deduct 810 from 849 and we're left with 39.
Fetch the next digit (1) from the dividend, attach it to 39 and continue: 391 / 90

Advancing to step 5:
90 goes into 391 4 times with a remainder of 31.
Put 4 as the next digit of the answer. 
Result so far: 194.0
The remainder is 31 after subtracting 360 from 391.
Take the next digit (4) from the dividend and append it to 31, then repeat: 314 / 90

On to step 6:
When dividing 314 by 90, we get 3 with a remainder of 44.
Record the quotient 3 as the next digit in the result. 
Result so far: 1943.0
The remainder is 44 after subtracting 270 from 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 7:
When dividing 440 by 90, we get 4 with a remainder of 80.
Put 4 as the next digit of the answer. 
Result so far: 1943.4
Subtracting 360 from 440 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 8:
90 can be fit into 800 8 times, resulting in a remainder of 80.
Put 8 as the next digit of the answer. 
Result so far: 1943.48
Deduct 720 from 800 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 9:
90 can be fit into 800 8 times, resulting in a remainder of 80.
Put 8 as the next digit of the answer. 
Result so far: 1943.488
The remainder is 80 after subtracting 720 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The quotient of the division is 1943.488, and the remainder is 0.008.
