30292688 ÷ 145 
The aim is to understand the frequency of 145 in 30292688.

Going ahead to step 1:
145 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 145

Step 2:
If we divide 30 by 145, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Bring next digit (2) of the dividend behind the 30 and repeat the process: 302 / 145

Step 3:
If we divide 302 by 145, we get 2 and a remainder of 12.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 290 from 302 leaves us with 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 145

Moving on to step 4:
145 goes into 129 0 times with a remainder of 129.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtracting 0 from 129 leaves us with 129.
Bring next digit (2) of the dividend behind the 129 and repeat the process: 1292 / 145

Moving on to step 5:
When dividing 1292 by 145, we get 8 with a remainder of 132.
Use 8 as the next digit of our solution. 
Result so far: 208.0
If we subtract 1160 from 1292, we get 132.
Fetch the next digit (6) from the dividend, attach it to 132 and continue: 1326 / 145

On to step 6:
145 can be fit into 1326 9 times, resulting in a remainder of 21.
The next digit of our result is 9. 
Result so far: 2089.0
The remainder is 21 after subtracting 1305 from 1326.
Bring next digit (8) of the dividend behind the 21 and repeat the process: 218 / 145

Step 7:
145 goes into 218 1 times with a remainder of 73.
The number 1 becomes the next digit in our result. 
Result so far: 20891.0
Subtract 145 from 218 to get 73.
Bring next digit (8) of the dividend behind the 73 and repeat the process: 738 / 145

On to step 8:
The number 145 fits into 738 5 times, leaving a remainder of 13.
Write down 5 as next digit of the result. 
Result so far: 208915.0
If we take 725 away from 738, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 9:
130 divided by 145 is 0 with a remainder of 130.
The next digit of our result is 0. 
Result so far: 208915.0
If we take 0 away from 130, 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.

Let's proceed to step 10:
The number 145 fits into 1300 8 times, leaving a remainder of 140.
Use 8 as the next digit of our solution. 
Result so far: 208915.08
If we take 1160 away from 1300, we end up 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.

Advancing to step 11:
When dividing 1400 by 145, we get 9 with a remainder of 95.
Put 9 as the next digit of the answer. 
Result so far: 208915.089
Subtract 1305 from 1400 to 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.

Going ahead to step 12:
When dividing 950 by 145, we get 6 with a remainder of 80.
Record the quotient 6 as the next digit in the result. 
Result so far: 208915.0896
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:
800 divided by 145 is 5 with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 208915.08965
If we subtract 725 from 800, we get 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:
The number 145 fits into 750 5 times, leaving a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 208915.089655
If we subtract 725 from 750, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The quotient of the division is 208915.089655, and the remainder is 2.5e-06.
