Let's divide 959416 by 90
The aim is to understand the frequency of 90 in 959416.

Let's proceed to step 1:
If we divide 9 by 90, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 90

Going ahead to step 2:
95 divided by 90 is 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 5 after subtracting 90 from 95.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 90

Moving on to step 3:
90 can be fit into 59 0 times, resulting in a remainder of 59.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 59 to get 59.
Fetch the next digit (4) from the dividend, attach it to 59 and continue: 594 / 90

Step 4:
90 goes into 594 6 times with a remainder of 54.
Put 6 as the next digit of the answer. 
Result so far: 106.0
The remainder is 54 after subtracting 540 from 594.
Take the next digit (1) from the dividend and append it to 54, then repeat: 541 / 90

Going ahead to step 5:
90 can be fit into 541 6 times, resulting in a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 1066.0
If we subtract 540 from 541, we get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 90

Let's proceed to step 6:
90 can be fit into 16 0 times, resulting in a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 10660.0
Subtract 0 from 16 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
If we divide 160 by 90, we get 1 and a remainder of 70.
Put 1 as the next digit of the answer. 
Result so far: 10660.1
Deduct 90 from 160 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.

Going ahead to step 8:
The number 90 fits into 700 7 times, leaving a remainder of 70.
The next digit of our result is 7. 
Result so far: 10660.17
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: 10660.177
The remainder is 70 after subtracting 630 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 10660.177, with a leftover of 0.007.
