We look at the division of 29391019 by 151 
The aim is to understand the frequency of 151 in 29391019.

Step 1:
2 divided by 151 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 151

Step 2:
151 goes into 29 0 times with a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 29 and we're left with 29.
Include the next digit (3) from the dividend after 29, then repeat: 293 / 151

Step 3:
When dividing 293 by 151, we get 1 with a remainder of 142.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 151 from 293, we get 142.
Include the next digit (9) from the dividend after 142, then repeat: 1429 / 151

Let's proceed to step 4:
1429 divided by 151 is 9 with a remainder of 70.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtract 1359 from 1429 to get 70.
Include the next digit (1) from the dividend after 70, then repeat: 701 / 151

Moving on to step 5:
The number 151 fits into 701 4 times, leaving a remainder of 97.
Put 4 as the next digit of the answer. 
Result so far: 194.0
Deduct 604 from 701 and we're left with 97.
Fetch the next digit (0) from the dividend, attach it to 97 and continue: 970 / 151

Step 6:
970 divided by 151 is 6 with a remainder of 64.
The next digit of our result is 6. 
Result so far: 1946.0
Subtract 906 from 970 to get 64.
Take the next digit (1) from the dividend and append it to 64, then repeat: 641 / 151

Advancing to step 7:
When dividing 641 by 151, we get 4 with a remainder of 37.
Write down 4 as next digit of the result. 
Result so far: 19464.0
Subtract 604 from 641 to get 37.
Append the next digit (9) from the dividend to 37 and continue with: 379 / 151

Step 8:
151 goes into 379 2 times with a remainder of 77.
The number 2 becomes the next digit in our result. 
Result so far: 194642.0
Deduct 302 from 379 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 9:
151 can be fit into 770 5 times, resulting in a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 194642.5
If we subtract 755 from 770, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 10:
150 divided by 151 is 0 with a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 194642.5
Subtract 0 from 150 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 11:
151 goes into 1500 9 times with a remainder of 141.
Write down 9 as next digit of the result. 
Result so far: 194642.509
Subtracting 1359 from 1500 leaves us with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Advancing to step 12:
The number 151 fits into 1410 9 times, leaving a remainder of 51.
Use 9 as the next digit of our solution. 
Result so far: 194642.5099
The remainder is 51 after subtracting 1359 from 1410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

After the division, we end up with 194642.5099 and a remainder of 0.00051.
