We're dividing 1821232 by 226 
The aim is to understand the frequency of 226 in 1821232.

On to step 1:
When dividing 1 by 226, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 226

Let's proceed to step 2:
The number 226 fits into 18 0 times, leaving a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Append the next digit (2) from the dividend to 18 and continue with: 182 / 226

Advancing to step 3:
182 divided by 226 is 0 with a remainder of 182.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 182, we get 182.
Take the next digit (1) from the dividend and append it to 182, then repeat: 1821 / 226

Going ahead to step 4:
The number 226 fits into 1821 8 times, leaving a remainder of 13.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 1808 from 1821 and we're left with 13.
Bring next digit (2) of the dividend behind the 13 and repeat the process: 132 / 226

Going ahead to step 5:
226 can be fit into 132 0 times, resulting in a remainder of 132.
Use 0 as the next digit of our solution. 
Result so far: 80.0
Deduct 0 from 132 and we're left with 132.
Take the next digit (3) from the dividend and append it to 132, then repeat: 1323 / 226

Let's proceed to step 6:
If we divide 1323 by 226, we get 5 and a remainder of 193.
Put 5 as the next digit of the answer. 
Result so far: 805.0
Subtracting 1130 from 1323 leaves us with 193.
Append the next digit (2) from the dividend to 193 and continue with: 1932 / 226

Going ahead to step 7:
The number 226 fits into 1932 8 times, leaving a remainder of 124.
Write down 8 as next digit of the result. 
Result so far: 8058.0
If we take 1808 away from 1932, we end up with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Going ahead to step 8:
When dividing 1240 by 226, we get 5 with a remainder of 110.
Record the quotient 5 as the next digit in the result. 
Result so far: 8058.5
If we take 1130 away from 1240, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 9:
The number 226 fits into 1100 4 times, leaving a remainder of 196.
The number 4 becomes the next digit in our result. 
Result so far: 8058.54
The remainder is 196 after subtracting 904 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Moving on to step 10:
When dividing 1960 by 226, we get 8 with a remainder of 152.
Write down 8 as next digit of the result. 
Result so far: 8058.548
Subtracting 1808 from 1960 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 11:
226 goes into 1520 6 times with a remainder of 164.
Record the quotient 6 as the next digit in the result. 
Result so far: 8058.5486
If we take 1356 away from 1520, we end up with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Moving on to step 12:
1640 divided by 226 is 7 with a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 8058.54867
Subtracting 1582 from 1640 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 13:
When dividing 580 by 226, we get 2 with a remainder of 128.
Put 2 as the next digit of the answer. 
Result so far: 8058.548672
Deduct 452 from 580 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 14:
When dividing 1280 by 226, we get 5 with a remainder of 150.
Put 5 as the next digit of the answer. 
Result so far: 8058.5486725
If we take 1130 away from 1280, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 15:
226 goes into 1500 6 times with a remainder of 144.
The number 6 becomes the next digit in our result. 
Result so far: 8058.54867256
If we take 1356 away from 1500, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Our division results in 8058.54867256 with a remaining 1.44e-07.
