74197223 ÷ 226 
The aim is to understand the frequency of 226 in 74197223.

On to step 1:
226 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 226

Going ahead to step 2:
The number 226 fits into 74 0 times, leaving a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 74 after subtracting 0 from 74.
Grab the next digit (1) from the dividend, add it to 74, then carry on: 741 / 226

Going ahead to step 3:
226 goes into 741 3 times with a remainder of 63.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 678 from 741 leaves us with 63.
Grab the next digit (9) from the dividend, add it to 63, then carry on: 639 / 226

Moving on to step 4:
If we divide 639 by 226, we get 2 and a remainder of 187.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
If we take 452 away from 639, we end up with 187.
Append the next digit (7) from the dividend to 187 and continue with: 1877 / 226

Moving on to step 5:
1877 divided by 226 is 8 with a remainder of 69.
Record the quotient 8 as the next digit in the result. 
Result so far: 328.0
Deduct 1808 from 1877 and we're left with 69.
Include the next digit (2) from the dividend after 69, then repeat: 692 / 226

On to step 6:
The number 226 fits into 692 3 times, leaving a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 3283.0
If we subtract 678 from 692, we get 14.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 226

Advancing to step 7:
If we divide 142 by 226, we get 0 and a remainder of 142.
Write down 0 as next digit of the result. 
Result so far: 32830.0
The remainder is 142 after subtracting 0 from 142.
Grab the next digit (3) from the dividend, add it to 142, then carry on: 1423 / 226

Going ahead to step 8:
1423 divided by 226 is 6 with a remainder of 67.
Put 6 as the next digit of the answer. 
Result so far: 328306.0
The remainder is 67 after subtracting 1356 from 1423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 9:
The number 226 fits into 670 2 times, leaving a remainder of 218.
The next digit of our result is 2. 
Result so far: 328306.2
If we subtract 452 from 670, we get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

On to step 10:
The number 226 fits into 2180 9 times, leaving a remainder of 146.
Write down 9 as next digit of the result. 
Result so far: 328306.29
If we take 2034 away from 2180, we end up with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Moving on to step 11:
If we divide 1460 by 226, we get 6 and a remainder of 104.
The next digit of our result is 6. 
Result so far: 328306.296
The remainder is 104 after subtracting 1356 from 1460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 12:
When dividing 1040 by 226, we get 4 with a remainder of 136.
Record the quotient 4 as the next digit in the result. 
Result so far: 328306.2964
Subtracting 904 from 1040 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 13:
1360 divided by 226 is 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 328306.29646
If we subtract 1356 from 1360, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 14:
When dividing 40 by 226, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 328306.29646
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 15:
226 can be fit into 400 1 times, resulting in a remainder of 174.
The next digit of our result is 1. 
Result so far: 328306.2964601
If we take 226 away from 400, we end up with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Moving on to step 16:
226 can be fit into 1740 7 times, resulting in a remainder of 158.
The next digit of our result is 7. 
Result so far: 328306.29646017
If we take 1582 away from 1740, we end up with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

After the division, we end up with 328306.29646017 and a remainder of 1.58e-07.
