We divide 186472 by 90
The aim is to understand the frequency of 90 in 186472.

Going ahead to step 1:
1 divided by 90 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 90

Moving on to step 2:
When dividing 18 by 90, we get 0 with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Fetch the next digit (6) from the dividend, attach it to 18 and continue: 186 / 90

Moving on to step 3:
The number 90 fits into 186 2 times, leaving a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 180 away from 186, we end up with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 90

Step 4:
90 goes into 64 0 times with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 20.0
The remainder is 64 after subtracting 0 from 64.
Bring next digit (7) of the dividend behind the 64 and repeat the process: 647 / 90

Step 5:
90 goes into 647 7 times with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 207.0
The remainder is 17 after subtracting 630 from 647.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 90

Going ahead to step 6:
90 can be fit into 172 1 times, resulting in a remainder of 82.
Put 1 as the next digit of the answer. 
Result so far: 2071.0
Subtracting 90 from 172 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 7:
820 divided by 90 is 9 with a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 2071.9
If we subtract 810 from 820, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
90 goes into 100 1 times with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 2071.91
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
90 goes into 100 1 times with a remainder of 10.
The next digit of our result is 1. 
Result so far: 2071.911
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 2071.911, and the remainder is 0.001.
