We're dividing 37192 by 90 
The aim is to understand the frequency of 90 in 37192.

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.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 90

Moving on to step 2:
90 goes into 37 0 times with a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 37 and we're left with 37.
Fetch the next digit (1) from the dividend, attach it to 37 and continue: 371 / 90

Step 3:
90 goes into 371 4 times with a remainder of 11.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 360 from 371 to get 11.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 90

On to step 4:
90 can be fit into 119 1 times, resulting in a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 41.0
Subtracting 90 from 119 leaves us with 29.
Bring next digit (2) of the dividend behind the 29 and repeat the process: 292 / 90

Moving on to step 5:
90 can be fit into 292 3 times, resulting in a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 413.0
The remainder is 22 after subtracting 270 from 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 6:
The number 90 fits into 220 2 times, leaving a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 413.2
Subtracting 180 from 220 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 7:
90 can be fit into 400 4 times, resulting in a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 413.24
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
If we divide 400 by 90, we get 4 and a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 413.244
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 413.244 and a remainder of 0.004.
