737411 ÷ 90 
The aim is to understand the frequency of 90 in 737411.

On to step 1:
7 divided by 90 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 90

Going ahead to step 2:
The number 90 fits into 73 0 times, leaving a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 73, we get 73.
Grab the next digit (7) from the dividend, add it to 73, then carry on: 737 / 90

Let's proceed to step 3:
90 goes into 737 8 times with a remainder of 17.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 720 from 737, we get 17.
Include the next digit (4) from the dividend after 17, then repeat: 174 / 90

Going ahead to step 4:
174 divided by 90 is 1 with a remainder of 84.
The next digit of our result is 1. 
Result so far: 81.0
Deduct 90 from 174 and we're left with 84.
Include the next digit (1) from the dividend after 84, then repeat: 841 / 90

Let's proceed to step 5:
90 can be fit into 841 9 times, resulting in a remainder of 31.
The next digit of our result is 9. 
Result so far: 819.0
The remainder is 31 after subtracting 810 from 841.
Bring next digit (1) of the dividend behind the 31 and repeat the process: 311 / 90

On to step 6:
When dividing 311 by 90, we get 3 with a remainder of 41.
The number 3 becomes the next digit in our result. 
Result so far: 8193.0
The remainder is 41 after subtracting 270 from 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 7:
When dividing 410 by 90, we get 4 with a remainder of 50.
The number 4 becomes the next digit in our result. 
Result so far: 8193.4
If we subtract 360 from 410, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
The number 90 fits into 500 5 times, leaving a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 8193.45
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 9:
500 divided by 90 is 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 8193.455
Subtracting 450 from 500 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final result is 8193.455 with a remainder of 0.005.
