2270397 ÷ 158 
The aim is to understand the frequency of 158 in 2270397.

Moving on to step 1:
2 divided by 158 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 158

Step 2:
When dividing 22 by 158, we get 0 with a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 22 leaves us with 22.
Bring next digit (7) of the dividend behind the 22 and repeat the process: 227 / 158

Let's proceed to step 3:
227 divided by 158 is 1 with a remainder of 69.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 158 from 227 and we're left with 69.
Fetch the next digit (0) from the dividend, attach it to 69 and continue: 690 / 158

Step 4:
158 goes into 690 4 times with a remainder of 58.
Use 4 as the next digit of our solution. 
Result so far: 14.0
The remainder is 58 after subtracting 632 from 690.
Take the next digit (3) from the dividend and append it to 58, then repeat: 583 / 158

Going ahead to step 5:
158 goes into 583 3 times with a remainder of 109.
Put 3 as the next digit of the answer. 
Result so far: 143.0
Deduct 474 from 583 and we're left with 109.
Take the next digit (9) from the dividend and append it to 109, then repeat: 1099 / 158

Step 6:
The number 158 fits into 1099 6 times, leaving a remainder of 151.
Use 6 as the next digit of our solution. 
Result so far: 1436.0
Subtracting 948 from 1099 leaves us with 151.
Take the next digit (7) from the dividend and append it to 151, then repeat: 1517 / 158

On to step 7:
1517 divided by 158 is 9 with a remainder of 95.
The next digit of our result is 9. 
Result so far: 14369.0
If we take 1422 away from 1517, we end up with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 8:
158 goes into 950 6 times with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 14369.6
Subtract 948 from 950 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
The number 158 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 14369.6
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
If we divide 200 by 158, we get 1 and a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 14369.601
If we take 158 away from 200, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 11:
420 divided by 158 is 2 with a remainder of 104.
Use 2 as the next digit of our solution. 
Result so far: 14369.6012
Subtract 316 from 420 to get 104.
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:
158 can be fit into 1040 6 times, resulting in a remainder of 92.
The number 6 becomes the next digit in our result. 
Result so far: 14369.60126
Subtracting 948 from 1040 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 13:
158 can be fit into 920 5 times, resulting in a remainder of 130.
The next digit of our result is 5. 
Result so far: 14369.601265
If we take 790 away from 920, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 14:
158 can be fit into 1300 8 times, resulting in a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 14369.6012658
Subtracting 1264 from 1300 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 15:
The number 158 fits into 360 2 times, leaving a remainder of 44.
The next digit of our result is 2. 
Result so far: 14369.60126582
The remainder is 44 after subtracting 316 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Our division results in 14369.60126582 with a remaining 4.4e-08.
