We're dividing 975418 by 90 
The aim is to understand the frequency of 90 in 975418.

On to step 1:
The number 90 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 90

Let's proceed to step 2:
90 can be fit into 97 1 times, resulting in a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 7 after subtracting 90 from 97.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 90

Going ahead to step 3:
90 can be fit into 75 0 times, resulting in a remainder of 75.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 75 after subtracting 0 from 75.
Bring next digit (4) of the dividend behind the 75 and repeat the process: 754 / 90

On to step 4:
The number 90 fits into 754 8 times, leaving a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 108.0
Deduct 720 from 754 and we're left with 34.
Grab the next digit (1) from the dividend, add it to 34, then carry on: 341 / 90

On to step 5:
If we divide 341 by 90, we get 3 and a remainder of 71.
The number 3 becomes the next digit in our result. 
Result so far: 1083.0
The remainder is 71 after subtracting 270 from 341.
Take the next digit (8) from the dividend and append it to 71, then repeat: 718 / 90

Going ahead to step 6:
When dividing 718 by 90, we get 7 with a remainder of 88.
Write down 7 as next digit of the result. 
Result so far: 10837.0
The remainder is 88 after subtracting 630 from 718.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 7:
The number 90 fits into 880 9 times, leaving a remainder of 70.
The next digit of our result is 9. 
Result so far: 10837.9
The remainder is 70 after subtracting 810 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 8:
When dividing 700 by 90, we get 7 with a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 10837.97
Deduct 630 from 700 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 9:
90 can be fit into 700 7 times, resulting in a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 10837.977
Deduct 630 from 700 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

In conclusion, the division gives 10837.977 with a balance of 0.007.
