Let's divide 286701 by 90
The aim is to understand the frequency of 90 in 286701.

Going ahead to step 1:
90 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 90

Advancing to step 2:
90 goes into 28 0 times with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Bring next digit (6) of the dividend behind the 28 and repeat the process: 286 / 90

Let's proceed to step 3:
If we divide 286 by 90, we get 3 and a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 270 from 286 to get 16.
Append the next digit (7) from the dividend to 16 and continue with: 167 / 90

Step 4:
If we divide 167 by 90, we get 1 and a remainder of 77.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
If we take 90 away from 167, we end up with 77.
Grab the next digit (0) from the dividend, add it to 77, then carry on: 770 / 90

Going ahead to step 5:
90 goes into 770 8 times with a remainder of 50.
Write down 8 as next digit of the result. 
Result so far: 318.0
The remainder is 50 after subtracting 720 from 770.
Take the next digit (1) from the dividend and append it to 50, then repeat: 501 / 90

Step 6:
90 goes into 501 5 times with a remainder of 51.
The next digit of our result is 5. 
Result so far: 3185.0
Subtract 450 from 501 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 7:
If we divide 510 by 90, we get 5 and a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 3185.5
Deduct 450 from 510 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 8:
90 can be fit into 600 6 times, resulting in a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 3185.56
Deduct 540 from 600 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
If we divide 600 by 90, we get 6 and a remainder of 60.
The next digit of our result is 6. 
Result so far: 3185.566
Subtract 540 from 600 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The quotient of the division is 3185.566, and the remainder is 0.006.
