We look at the division of 40578439 by 151 
The aim is to understand the frequency of 151 in 40578439.

Advancing to step 1:
4 divided by 151 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 151

Moving on to step 2:
151 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Take the next digit (5) from the dividend and append it to 40, then repeat: 405 / 151

Moving on to step 3:
405 divided by 151 is 2 with a remainder of 103.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 302 from 405 to get 103.
Include the next digit (7) from the dividend after 103, then repeat: 1037 / 151

On to step 4:
151 can be fit into 1037 6 times, resulting in a remainder of 131.
Write down 6 as next digit of the result. 
Result so far: 26.0
The remainder is 131 after subtracting 906 from 1037.
Grab the next digit (8) from the dividend, add it to 131, then carry on: 1318 / 151

Let's proceed to step 5:
151 goes into 1318 8 times with a remainder of 110.
The number 8 becomes the next digit in our result. 
Result so far: 268.0
Subtract 1208 from 1318 to get 110.
Fetch the next digit (4) from the dividend, attach it to 110 and continue: 1104 / 151

On to step 6:
When dividing 1104 by 151, we get 7 with a remainder of 47.
Record the quotient 7 as the next digit in the result. 
Result so far: 2687.0
If we take 1057 away from 1104, we end up with 47.
Bring next digit (3) of the dividend behind the 47 and repeat the process: 473 / 151

Advancing to step 7:
The number 151 fits into 473 3 times, leaving a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 26873.0
If we subtract 453 from 473, we get 20.
Fetch the next digit (9) from the dividend, attach it to 20 and continue: 209 / 151

On to step 8:
151 can be fit into 209 1 times, resulting in a remainder of 58.
Record the quotient 1 as the next digit in the result. 
Result so far: 268731.0
If we take 151 away from 209, we end up 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 9:
If we divide 580 by 151, we get 3 and a remainder of 127.
The number 3 becomes the next digit in our result. 
Result so far: 268731.3
Subtracting 453 from 580 leaves us with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

On to step 10:
151 goes into 1270 8 times with a remainder of 62.
Use 8 as the next digit of our solution. 
Result so far: 268731.38
Deduct 1208 from 1270 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 11:
151 can be fit into 620 4 times, resulting in a remainder of 16.
The next digit of our result is 4. 
Result so far: 268731.384
Deduct 604 from 620 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 12:
The number 151 fits into 160 1 times, leaving a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 268731.3841
If we subtract 151 from 160, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 13:
When dividing 90 by 151, we get 0 with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 268731.3841
If we subtract 0 from 90, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 14:
900 divided by 151 is 5 with a remainder of 145.
Put 5 as the next digit of the answer. 
Result so far: 268731.384105
If we take 755 away from 900, we end up with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Let's proceed to step 15:
If we divide 1450 by 151, we get 9 and a remainder of 91.
Record the quotient 9 as the next digit in the result. 
Result so far: 268731.3841059
The remainder is 91 after subtracting 1359 from 1450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Advancing to step 16:
If we divide 910 by 151, we get 6 and a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 268731.38410596
Subtracting 906 from 910 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 268731.38410596 with a balance of 4e-09.
