90080228 ÷ 443 
The aim is to understand the frequency of 443 in 90080228.

Moving on to step 1:
If we divide 9 by 443, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 443

Step 2:
90 divided by 443 is 0 with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Take the next digit (0) from the dividend and append it to 90, then repeat: 900 / 443

Advancing to step 3:
When dividing 900 by 443, we get 2 with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 886 from 900 to get 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 443

Advancing to step 4:
When dividing 148 by 443, we get 0 with a remainder of 148.
Write down 0 as next digit of the result. 
Result so far: 20.0
The remainder is 148 after subtracting 0 from 148.
Take the next digit (0) from the dividend and append it to 148, then repeat: 1480 / 443

Step 5:
443 goes into 1480 3 times with a remainder of 151.
Write down 3 as next digit of the result. 
Result so far: 203.0
If we take 1329 away from 1480, we end up with 151.
Take the next digit (2) from the dividend and append it to 151, then repeat: 1512 / 443

Let's proceed to step 6:
443 can be fit into 1512 3 times, resulting in a remainder of 183.
Use 3 as the next digit of our solution. 
Result so far: 2033.0
The remainder is 183 after subtracting 1329 from 1512.
Include the next digit (2) from the dividend after 183, then repeat: 1832 / 443

Let's proceed to step 7:
If we divide 1832 by 443, we get 4 and a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 20334.0
If we subtract 1772 from 1832, we get 60.
Include the next digit (8) from the dividend after 60, then repeat: 608 / 443

Moving on to step 8:
When dividing 608 by 443, we get 1 with a remainder of 165.
Use 1 as the next digit of our solution. 
Result so far: 203341.0
The remainder is 165 after subtracting 443 from 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Moving on to step 9:
If we divide 1650 by 443, we get 3 and a remainder of 321.
Put 3 as the next digit of the answer. 
Result so far: 203341.3
Subtracting 1329 from 1650 leaves us with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Step 10:
3210 divided by 443 is 7 with a remainder of 109.
Use 7 as the next digit of our solution. 
Result so far: 203341.37
The remainder is 109 after subtracting 3101 from 3210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Going ahead to step 11:
443 can be fit into 1090 2 times, resulting in a remainder of 204.
Record the quotient 2 as the next digit in the result. 
Result so far: 203341.372
If we take 886 away from 1090, we end up with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Moving on to step 12:
443 can be fit into 2040 4 times, resulting in a remainder of 268.
Record the quotient 4 as the next digit in the result. 
Result so far: 203341.3724
Deduct 1772 from 2040 and we're left with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Advancing to step 13:
2680 divided by 443 is 6 with a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 203341.37246
If we take 2658 away from 2680, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 14:
443 can be fit into 220 0 times, resulting in a remainder of 220.
Use 0 as the next digit of our solution. 
Result so far: 203341.37246
If we take 0 away from 220, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 15:
When dividing 2200 by 443, we get 4 with a remainder of 428.
Record the quotient 4 as the next digit in the result. 
Result so far: 203341.3724604
Subtract 1772 from 2200 to get 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Advancing to step 16:
The number 443 fits into 4280 9 times, leaving a remainder of 293.
Put 9 as the next digit of the answer. 
Result so far: 203341.37246049
The remainder is 293 after subtracting 3987 from 4280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

The quotient of the division is 203341.37246049, and the remainder is 2.93e-07.
