35488394 ÷ 145 
The aim is to understand the frequency of 145 in 35488394.

Advancing to step 1:
145 can be fit into 3 0 times, resulting in 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.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 145

On to step 2:
35 divided by 145 is 0 with a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Include the next digit (4) from the dividend after 35, then repeat: 354 / 145

Moving on to step 3:
354 divided by 145 is 2 with a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 290 from 354 leaves us with 64.
Bring next digit (8) of the dividend behind the 64 and repeat the process: 648 / 145

Let's proceed to step 4:
648 divided by 145 is 4 with a remainder of 68.
The next digit of our result is 4. 
Result so far: 24.0
Subtract 580 from 648 to get 68.
Take the next digit (8) from the dividend and append it to 68, then repeat: 688 / 145

Advancing to step 5:
145 goes into 688 4 times with a remainder of 108.
Put 4 as the next digit of the answer. 
Result so far: 244.0
Deduct 580 from 688 and we're left with 108.
Fetch the next digit (3) from the dividend, attach it to 108 and continue: 1083 / 145

Advancing to step 6:
1083 divided by 145 is 7 with a remainder of 68.
Put 7 as the next digit of the answer. 
Result so far: 2447.0
If we subtract 1015 from 1083, we get 68.
Append the next digit (9) from the dividend to 68 and continue with: 689 / 145

Moving on to step 7:
145 can be fit into 689 4 times, resulting in a remainder of 109.
The next digit of our result is 4. 
Result so far: 24474.0
If we take 580 away from 689, we end up with 109.
Take the next digit (4) from the dividend and append it to 109, then repeat: 1094 / 145

Step 8:
If we divide 1094 by 145, we get 7 and a remainder of 79.
Record the quotient 7 as the next digit in the result. 
Result so far: 244747.0
Deduct 1015 from 1094 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 9:
When dividing 790 by 145, we get 5 with a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 244747.5
If we subtract 725 from 790, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 10:
The number 145 fits into 650 4 times, leaving a remainder of 70.
Use 4 as the next digit of our solution. 
Result so far: 244747.54
Deduct 580 from 650 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 11:
When dividing 700 by 145, we get 4 with a remainder of 120.
Record the quotient 4 as the next digit in the result. 
Result so far: 244747.544
If we take 580 away from 700, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Our division results in 244747.544 with a remaining 0.012.
