Let's divide 610793 by 90
The aim is to understand the frequency of 90 in 610793.

Moving on to step 1:
The number 90 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 90

Going ahead to step 2:
90 goes into 61 0 times with a remainder of 61.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 61, we end up with 61.
Append the next digit (0) from the dividend to 61 and continue with: 610 / 90

Let's proceed to step 3:
90 goes into 610 6 times with a remainder of 70.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 540 from 610, we get 70.
Grab the next digit (7) from the dividend, add it to 70, then carry on: 707 / 90

Let's proceed to step 4:
The number 90 fits into 707 7 times, leaving a remainder of 77.
Use 7 as the next digit of our solution. 
Result so far: 67.0
Subtract 630 from 707 to get 77.
Bring next digit (9) of the dividend behind the 77 and repeat the process: 779 / 90

Going ahead to step 5:
When dividing 779 by 90, we get 8 with a remainder of 59.
Put 8 as the next digit of the answer. 
Result so far: 678.0
If we subtract 720 from 779, we get 59.
Grab the next digit (3) from the dividend, add it to 59, then carry on: 593 / 90

Going ahead to step 6:
90 goes into 593 6 times with a remainder of 53.
The number 6 becomes the next digit in our result. 
Result so far: 6786.0
If we take 540 away from 593, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 7:
530 divided by 90 is 5 with a remainder of 80.
Record the quotient 5 as the next digit in the result. 
Result so far: 6786.5
Subtracting 450 from 530 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 8:
The number 90 fits into 800 8 times, leaving a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 6786.58
Deduct 720 from 800 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 9:
When dividing 800 by 90, we get 8 with a remainder of 80.
The next digit of our result is 8. 
Result so far: 6786.588
Subtracting 720 from 800 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final outcome is 6786.588, with a leftover of 0.008.
