29669012 divided by 145 
The aim is to understand the frequency of 145 in 29669012.

On to step 1:
145 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 145

Let's proceed to step 2:
The number 145 fits into 29 0 times, leaving a remainder of 29.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 29 after subtracting 0 from 29.
Bring next digit (6) of the dividend behind the 29 and repeat the process: 296 / 145

On to step 3:
145 goes into 296 2 times with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 290 from 296 leaves us with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 145

Moving on to step 4:
The number 145 fits into 66 0 times, leaving a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtracting 0 from 66 leaves us with 66.
Fetch the next digit (9) from the dividend, attach it to 66 and continue: 669 / 145

Moving on to step 5:
When dividing 669 by 145, we get 4 with a remainder of 89.
Write down 4 as next digit of the result. 
Result so far: 204.0
Subtracting 580 from 669 leaves us with 89.
Take the next digit (0) from the dividend and append it to 89, then repeat: 890 / 145

On to step 6:
If we divide 890 by 145, we get 6 and a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 2046.0
If we take 870 away from 890, we end up with 20.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 145

Going ahead to step 7:
201 divided by 145 is 1 with a remainder of 56.
Write down 1 as next digit of the result. 
Result so far: 20461.0
Subtract 145 from 201 to get 56.
Take the next digit (2) from the dividend and append it to 56, then repeat: 562 / 145

On to step 8:
562 divided by 145 is 3 with a remainder of 127.
Put 3 as the next digit of the answer. 
Result so far: 204613.0
Subtract 435 from 562 to get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Step 9:
The number 145 fits into 1270 8 times, leaving a remainder of 110.
The next digit of our result is 8. 
Result so far: 204613.8
Deduct 1160 from 1270 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 10:
The number 145 fits into 1100 7 times, leaving a remainder of 85.
Use 7 as the next digit of our solution. 
Result so far: 204613.87
Subtracting 1015 from 1100 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 11:
If we divide 850 by 145, we get 5 and a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 204613.875
If we subtract 725 from 850, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 12:
145 goes into 1250 8 times with a remainder of 90.
Use 8 as the next digit of our solution. 
Result so far: 204613.8758
Subtract 1160 from 1250 to 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.

Advancing to step 13:
If we divide 900 by 145, we get 6 and a remainder of 30.
The next digit of our result is 6. 
Result so far: 204613.87586
The remainder is 30 after subtracting 870 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 14:
300 divided by 145 is 2 with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 204613.875862
Subtracting 290 from 300 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 15:
When dividing 100 by 145, we get 0 with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 204613.875862
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 16:
If we divide 1000 by 145, we get 6 and a remainder of 130.
The next digit of our result is 6. 
Result so far: 204613.87586206
If we take 870 away from 1000, 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.

The final outcome is 204613.87586206, with a leftover of 1.3e-07.
