307117 divided by 90 
The aim is to understand the frequency of 90 in 307117.

Advancing to step 1:
90 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 90

Let's proceed to step 2:
90 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Bring next digit (7) of the dividend behind the 30 and repeat the process: 307 / 90

Moving on to step 3:
If we divide 307 by 90, we get 3 and a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 270 from 307 to get 37.
Fetch the next digit (1) from the dividend, attach it to 37 and continue: 371 / 90

Going ahead to step 4:
If we divide 371 by 90, we get 4 and a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
Subtract 360 from 371 to get 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 90

On to step 5:
The number 90 fits into 111 1 times, leaving a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 341.0
Subtract 90 from 111 to get 21.
Fetch the next digit (7) from the dividend, attach it to 21 and continue: 217 / 90

Let's proceed to step 6:
The number 90 fits into 217 2 times, leaving a remainder of 37.
Record the quotient 2 as the next digit in the result. 
Result so far: 3412.0
If we subtract 180 from 217, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 7:
90 can be fit into 370 4 times, resulting in a remainder of 10.
The next digit of our result is 4. 
Result so far: 3412.4
Deduct 360 from 370 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
90 can be fit into 100 1 times, resulting in a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 3412.41
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
If we divide 100 by 90, we get 1 and a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 3412.411
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 3412.411 with a remaining 0.001.
