90510083 ÷ 226 
The aim is to understand the frequency of 226 in 90510083.

Step 1:
When dividing 9 by 226, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 226

Going ahead to step 2:
The number 226 fits into 90 0 times, leaving a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Fetch the next digit (5) from the dividend, attach it to 90 and continue: 905 / 226

Step 3:
When dividing 905 by 226, we get 4 with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 904 away from 905, we end up with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 226

Moving on to step 4:
If we divide 11 by 226, we get 0 and a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
Subtract 0 from 11 to get 11.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 226

On to step 5:
The number 226 fits into 110 0 times, leaving a remainder of 110.
The next digit of our result is 0. 
Result so far: 400.0
Subtracting 0 from 110 leaves us with 110.
Take the next digit (0) from the dividend and append it to 110, then repeat: 1100 / 226

Moving on to step 6:
226 goes into 1100 4 times with a remainder of 196.
Write down 4 as next digit of the result. 
Result so far: 4004.0
If we take 904 away from 1100, we end up with 196.
Bring next digit (8) of the dividend behind the 196 and repeat the process: 1968 / 226

Step 7:
The number 226 fits into 1968 8 times, leaving a remainder of 160.
Use 8 as the next digit of our solution. 
Result so far: 40048.0
Subtracting 1808 from 1968 leaves us with 160.
Fetch the next digit (3) from the dividend, attach it to 160 and continue: 1603 / 226

Moving on to step 8:
When dividing 1603 by 226, we get 7 with a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 400487.0
If we take 1582 away from 1603, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 9:
The number 226 fits into 210 0 times, leaving a remainder of 210.
Write down 0 as next digit of the result. 
Result so far: 400487.0
If we take 0 away from 210, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 10:
226 can be fit into 2100 9 times, resulting in a remainder of 66.
Use 9 as the next digit of our solution. 
Result so far: 400487.09
Deduct 2034 from 2100 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 11:
When dividing 660 by 226, we get 2 with a remainder of 208.
The next digit of our result is 2. 
Result so far: 400487.092
If we subtract 452 from 660, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Let's proceed to step 12:
2080 divided by 226 is 9 with a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 400487.0929
Subtract 2034 from 2080 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 13:
226 can be fit into 460 2 times, resulting in a remainder of 8.
The next digit of our result is 2. 
Result so far: 400487.09292
The remainder is 8 after subtracting 452 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 14:
226 goes into 80 0 times with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 400487.09292
If we subtract 0 from 80, we get 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 15:
226 can be fit into 800 3 times, resulting in a remainder of 122.
The number 3 becomes the next digit in our result. 
Result so far: 400487.0929203
Subtract 678 from 800 to get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Advancing to step 16:
226 goes into 1220 5 times with a remainder of 90.
Use 5 as the next digit of our solution. 
Result so far: 400487.09292035
Subtracting 1130 from 1220 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

After the division, we end up with 400487.09292035 and a remainder of 9e-08.
