We look at the division of 40488856 by 145 
The aim is to understand the frequency of 145 in 40488856.

Let's proceed to step 1:
145 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 145

Step 2:
145 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Include the next digit (4) from the dividend after 40, then repeat: 404 / 145

Going ahead to step 3:
If we divide 404 by 145, we get 2 and a remainder of 114.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 290 from 404 leaves us with 114.
Take the next digit (8) from the dividend and append it to 114, then repeat: 1148 / 145

Let's proceed to step 4:
145 can be fit into 1148 7 times, resulting in a remainder of 133.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
The remainder is 133 after subtracting 1015 from 1148.
Fetch the next digit (8) from the dividend, attach it to 133 and continue: 1338 / 145

Advancing to step 5:
If we divide 1338 by 145, we get 9 and a remainder of 33.
Use 9 as the next digit of our solution. 
Result so far: 279.0
If we take 1305 away from 1338, we end up with 33.
Include the next digit (8) from the dividend after 33, then repeat: 338 / 145

On to step 6:
145 can be fit into 338 2 times, resulting in a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 2792.0
Subtract 290 from 338 to get 48.
Take the next digit (5) from the dividend and append it to 48, then repeat: 485 / 145

On to step 7:
485 divided by 145 is 3 with a remainder of 50.
Write down 3 as next digit of the result. 
Result so far: 27923.0
If we subtract 435 from 485, we get 50.
Take the next digit (6) from the dividend and append it to 50, then repeat: 506 / 145

Going ahead to step 8:
If we divide 506 by 145, we get 3 and a remainder of 71.
Write down 3 as next digit of the result. 
Result so far: 279233.0
Deduct 435 from 506 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 9:
145 can be fit into 710 4 times, resulting in a remainder of 130.
The number 4 becomes the next digit in our result. 
Result so far: 279233.4
The remainder is 130 after subtracting 580 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 10:
1300 divided by 145 is 8 with a remainder of 140.
Put 8 as the next digit of the answer. 
Result so far: 279233.48
Deduct 1160 from 1300 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 11:
145 can be fit into 1400 9 times, resulting in a remainder of 95.
Put 9 as the next digit of the answer. 
Result so far: 279233.489
If we subtract 1305 from 1400, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Step 12:
If we divide 950 by 145, we get 6 and a remainder of 80.
Use 6 as the next digit of our solution. 
Result so far: 279233.4896
Subtracting 870 from 950 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 13:
If we divide 800 by 145, we get 5 and a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 279233.48965
If we take 725 away from 800, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 14:
When dividing 750 by 145, we get 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 279233.489655
Deduct 725 from 750 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 279233.489655 with a remaining 2.5e-06.
