We look at the division of 42528912 by 145 
The aim is to understand the frequency of 145 in 42528912.

Let's proceed to step 1:
145 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 145

On to step 2:
The number 145 fits into 42 0 times, leaving a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Fetch the next digit (5) from the dividend, attach it to 42 and continue: 425 / 145

Going ahead to step 3:
When dividing 425 by 145, we get 2 with a remainder of 135.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 290 from 425 and we're left with 135.
Grab the next digit (2) from the dividend, add it to 135, then carry on: 1352 / 145

Step 4:
If we divide 1352 by 145, we get 9 and a remainder of 47.
Write down 9 as next digit of the result. 
Result so far: 29.0
If we subtract 1305 from 1352, we get 47.
Include the next digit (8) from the dividend after 47, then repeat: 478 / 145

Step 5:
145 can be fit into 478 3 times, resulting in a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 293.0
If we take 435 away from 478, we end up with 43.
Include the next digit (9) from the dividend after 43, then repeat: 439 / 145

Advancing to step 6:
145 can be fit into 439 3 times, resulting in a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 2933.0
Subtract 435 from 439 to get 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 145

Step 7:
The number 145 fits into 41 0 times, leaving a remainder of 41.
Use 0 as the next digit of our solution. 
Result so far: 29330.0
The remainder is 41 after subtracting 0 from 41.
Bring next digit (2) of the dividend behind the 41 and repeat the process: 412 / 145

Advancing to step 8:
If we divide 412 by 145, we get 2 and a remainder of 122.
Write down 2 as next digit of the result. 
Result so far: 293302.0
If we take 290 away from 412, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Step 9:
145 goes into 1220 8 times with a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 293302.8
If we subtract 1160 from 1220, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
The number 145 fits into 600 4 times, leaving a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 293302.84
Subtracting 580 from 600 leaves us 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.

Step 11:
When dividing 200 by 145, we get 1 with a remainder of 55.
Put 1 as the next digit of the answer. 
Result so far: 293302.841
The remainder is 55 after subtracting 145 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 12:
145 can be fit into 550 3 times, resulting in a remainder of 115.
Put 3 as the next digit of the answer. 
Result so far: 293302.8413
Subtracting 435 from 550 leaves us with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Step 13:
If we divide 1150 by 145, we get 7 and a remainder of 135.
The number 7 becomes the next digit in our result. 
Result so far: 293302.84137
The remainder is 135 after subtracting 1015 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 14:
When dividing 1350 by 145, we get 9 with a remainder of 45.
Write down 9 as next digit of the result. 
Result so far: 293302.841379
Subtracting 1305 from 1350 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 15:
If we divide 450 by 145, we get 3 and a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 293302.8413793
Subtract 435 from 450 to 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.

Going ahead to step 16:
If we divide 150 by 145, we get 1 and a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 293302.84137931
Subtract 145 from 150 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 293302.84137931, with a leftover of 5e-09.
