35474572 ÷ 181 
The aim is to understand the frequency of 181 in 35474572.

Let's proceed to step 1:
If we divide 3 by 181, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 181

Let's proceed to step 2:
181 can be fit into 35 0 times, resulting in a remainder of 35.
The number 0 becomes the next digit in our result. 
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 / 181

Let's proceed to step 3:
181 goes into 354 1 times with a remainder of 173.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 181 from 354, we get 173.
Grab the next digit (7) from the dividend, add it to 173, then carry on: 1737 / 181

Advancing to step 4:
If we divide 1737 by 181, we get 9 and a remainder of 108.
Write down 9 as next digit of the result. 
Result so far: 19.0
Deduct 1629 from 1737 and we're left with 108.
Take the next digit (4) from the dividend and append it to 108, then repeat: 1084 / 181

Step 5:
181 goes into 1084 5 times with a remainder of 179.
Put 5 as the next digit of the answer. 
Result so far: 195.0
The remainder is 179 after subtracting 905 from 1084.
Grab the next digit (5) from the dividend, add it to 179, then carry on: 1795 / 181

Going ahead to step 6:
181 goes into 1795 9 times with a remainder of 166.
Use 9 as the next digit of our solution. 
Result so far: 1959.0
Deduct 1629 from 1795 and we're left with 166.
Grab the next digit (7) from the dividend, add it to 166, then carry on: 1667 / 181

Moving on to step 7:
181 goes into 1667 9 times with a remainder of 38.
The next digit of our result is 9. 
Result so far: 19599.0
If we subtract 1629 from 1667, we get 38.
Include the next digit (2) from the dividend after 38, then repeat: 382 / 181

Going ahead to step 8:
If we divide 382 by 181, we get 2 and a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 195992.0
Deduct 362 from 382 and we're left 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.

Moving on to step 9:
181 can be fit into 200 1 times, resulting in a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 195992.1
Deduct 181 from 200 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 10:
181 can be fit into 190 1 times, resulting in a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 195992.11
Deduct 181 from 190 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

After the division, we end up with 195992.11 and a remainder of 0.009.
