Let's divide 207270 by 90
The aim is to understand the frequency of 90 in 207270.

Moving on to step 1:
2 divided by 90 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 90

On to step 2:
90 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Bring next digit (7) of the dividend behind the 20 and repeat the process: 207 / 90

Step 3:
When dividing 207 by 90, we get 2 with a remainder of 27.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 180 from 207 to get 27.
Grab the next digit (2) from the dividend, add it to 27, then carry on: 272 / 90

Step 4:
272 divided by 90 is 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 23.0
Subtract 270 from 272 to get 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 90

Step 5:
The number 90 fits into 27 0 times, leaving a remainder of 27.
The next digit of our result is 0. 
Result so far: 230.0
Deduct 0 from 27 and we're left with 27.
Take the next digit (0) from the dividend and append it to 27, then repeat: 270 / 90

Let's proceed to step 6:
270 divided by 90 is 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 2303.0
Subtract 270 from 270 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.

Advancing to step 7:
0 divided by 90 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 2303.0
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.

Moving on to step 8:
90 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2303.0
If we subtract 0 from 0, 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.

Our division results in 2303.0 with a remaining 0.0.
