554588 ÷ 90 
The aim is to understand the frequency of 90 in 554588.

Moving on to step 1:
5 divided by 90 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 90

Advancing to step 2:
If we divide 55 by 90, we get 0 and a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Fetch the next digit (4) from the dividend, attach it to 55 and continue: 554 / 90

Moving on to step 3:
90 goes into 554 6 times with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 540 from 554 and we're left with 14.
Fetch the next digit (5) from the dividend, attach it to 14 and continue: 145 / 90

Advancing to step 4:
90 can be fit into 145 1 times, resulting in a remainder of 55.
Write down 1 as next digit of the result. 
Result so far: 61.0
Subtract 90 from 145 to get 55.
Fetch the next digit (8) from the dividend, attach it to 55 and continue: 558 / 90

Advancing to step 5:
When dividing 558 by 90, we get 6 with a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 616.0
If we subtract 540 from 558, we get 18.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 90

Going ahead to step 6:
90 goes into 188 2 times with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 6162.0
Deduct 180 from 188 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
If we divide 80 by 90, we get 0 and a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 6162.0
Deduct 0 from 80 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.

Advancing to step 8:
The number 90 fits into 800 8 times, leaving a remainder of 80.
Record the quotient 8 as the next digit in the result. 
Result so far: 6162.08
The remainder is 80 after subtracting 720 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 9:
If we divide 800 by 90, we get 8 and a remainder of 80.
Put 8 as the next digit of the answer. 
Result so far: 6162.088
The remainder is 80 after subtracting 720 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

In conclusion, the division gives 6162.088 with a balance of 0.008.
