16614 divided by 90 
The aim is to understand the frequency of 90 in 16614.

Moving on to step 1:
1 divided by 90 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 90

On to step 2:
90 can be fit into 16 0 times, resulting in a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Bring next digit (6) of the dividend behind the 16 and repeat the process: 166 / 90

Step 3:
The number 90 fits into 166 1 times, leaving a remainder of 76.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 90 from 166 and we're left with 76.
Grab the next digit (1) from the dividend, add it to 76, then carry on: 761 / 90

Moving on to step 4:
90 goes into 761 8 times with a remainder of 41.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Deduct 720 from 761 and we're left with 41.
Bring next digit (4) of the dividend behind the 41 and repeat the process: 414 / 90

Step 5:
414 divided by 90 is 4 with a remainder of 54.
Record the quotient 4 as the next digit in the result. 
Result so far: 184.0
The remainder is 54 after subtracting 360 from 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 6:
540 divided by 90 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 184.6
If we subtract 540 from 540, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
90 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 184.6
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
If we divide 0 by 90, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 184.6
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 184.6, and the remainder is 0.0.
