We look at the division of 119874 by 90 
The aim is to understand the frequency of 90 in 119874.

Moving on to step 1:
1 divided by 90 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 90

Moving on to step 2:
90 can be fit into 11 0 times, resulting in a remainder of 11.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 11 to get 11.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 90

Advancing to step 3:
The number 90 fits into 119 1 times, leaving a remainder of 29.
The next digit of our result is 1. 
Result so far: 1.0
If we take 90 away from 119, we end up with 29.
Append the next digit (8) from the dividend to 29 and continue with: 298 / 90

Advancing to step 4:
The number 90 fits into 298 3 times, leaving a remainder of 28.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 28 after subtracting 270 from 298.
Append the next digit (7) from the dividend to 28 and continue with: 287 / 90

Advancing to step 5:
90 can be fit into 287 3 times, resulting in a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 133.0
The remainder is 17 after subtracting 270 from 287.
Append the next digit (4) from the dividend to 17 and continue with: 174 / 90

Advancing to step 6:
90 can be fit into 174 1 times, resulting in a remainder of 84.
The number 1 becomes the next digit in our result. 
Result so far: 1331.0
Deduct 90 from 174 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 7:
90 can be fit into 840 9 times, resulting in a remainder of 30.
Record the quotient 9 as the next digit in the result. 
Result so far: 1331.9
Subtract 810 from 840 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.

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: 1331.93
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.

Step 9:
90 can be fit into 300 3 times, resulting in a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 1331.933
Deduct 270 from 300 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.

Our division results in 1331.933 with a remaining 0.003.
