885719 divided by 90 
The aim is to understand the frequency of 90 in 885719.

Going ahead to step 1:
If we divide 8 by 90, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 90

Advancing to step 2:
90 can be fit into 88 0 times, resulting in a remainder of 88.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 88 leaves us with 88.
Bring next digit (5) of the dividend behind the 88 and repeat the process: 885 / 90

Step 3:
The number 90 fits into 885 9 times, leaving a remainder of 75.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 810 from 885 to get 75.
Fetch the next digit (7) from the dividend, attach it to 75 and continue: 757 / 90

Let's proceed to step 4:
When dividing 757 by 90, we get 8 with a remainder of 37.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
If we take 720 away from 757, we end up with 37.
Take the next digit (1) from the dividend and append it to 37, then repeat: 371 / 90

Advancing to step 5:
When dividing 371 by 90, we get 4 with a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 984.0
The remainder is 11 after subtracting 360 from 371.
Fetch the next digit (9) from the dividend, attach it to 11 and continue: 119 / 90

Let's proceed to step 6:
90 can be fit into 119 1 times, resulting in a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 9841.0
Deduct 90 from 119 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 7:
290 divided by 90 is 3 with a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 9841.3
The remainder is 20 after subtracting 270 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
The number 90 fits into 200 2 times, leaving a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 9841.32
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
When dividing 200 by 90, we get 2 with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 9841.322
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 9841.322, and the remainder is 0.002.
