722924 divided by 90 
The aim is to understand the frequency of 90 in 722924.

Advancing to step 1:
The number 90 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 90

Moving on to step 2:
If we divide 72 by 90, we get 0 and a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Include the next digit (2) from the dividend after 72, then repeat: 722 / 90

Step 3:
90 can be fit into 722 8 times, resulting in a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 2 after subtracting 720 from 722.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 90

Moving on to step 4:
90 goes into 29 0 times with a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
If we take 0 away from 29, we end up with 29.
Bring next digit (2) of the dividend behind the 29 and repeat the process: 292 / 90

On to step 5:
292 divided by 90 is 3 with a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 803.0
Subtracting 270 from 292 leaves us with 22.
Bring next digit (4) of the dividend behind the 22 and repeat the process: 224 / 90

Moving on to step 6:
When dividing 224 by 90, we get 2 with a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 8032.0
If we take 180 away from 224, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 7:
90 can be fit into 440 4 times, resulting in a remainder of 80.
Put 4 as the next digit of the answer. 
Result so far: 8032.4
Deduct 360 from 440 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 8:
When dividing 800 by 90, we get 8 with a remainder of 80.
Record the quotient 8 as the next digit in the result. 
Result so far: 8032.48
If we take 720 away from 800, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 9:
When dividing 800 by 90, we get 8 with a remainder of 80.
The next digit of our result is 8. 
Result so far: 8032.488
The remainder is 80 after subtracting 720 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

After the division, we end up with 8032.488 and a remainder of 0.008.
