40351475 ÷ 181 
The aim is to understand the frequency of 181 in 40351475.

Advancing to step 1:
If we divide 4 by 181, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 181

Let's proceed to step 2:
If we divide 40 by 181, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Include the next digit (3) from the dividend after 40, then repeat: 403 / 181

Going ahead to step 3:
If we divide 403 by 181, we get 2 and a remainder of 41.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 362 away from 403, we end up with 41.
Bring next digit (5) of the dividend behind the 41 and repeat the process: 415 / 181

Step 4:
415 divided by 181 is 2 with a remainder of 53.
The next digit of our result is 2. 
Result so far: 22.0
The remainder is 53 after subtracting 362 from 415.
Grab the next digit (1) from the dividend, add it to 53, then carry on: 531 / 181

Moving on to step 5:
If we divide 531 by 181, we get 2 and a remainder of 169.
Use 2 as the next digit of our solution. 
Result so far: 222.0
Subtracting 362 from 531 leaves us with 169.
Grab the next digit (4) from the dividend, add it to 169, then carry on: 1694 / 181

Advancing to step 6:
When dividing 1694 by 181, we get 9 with a remainder of 65.
Put 9 as the next digit of the answer. 
Result so far: 2229.0
If we subtract 1629 from 1694, we get 65.
Bring next digit (7) of the dividend behind the 65 and repeat the process: 657 / 181

On to step 7:
181 goes into 657 3 times with a remainder of 114.
The next digit of our result is 3. 
Result so far: 22293.0
Subtract 543 from 657 to get 114.
Grab the next digit (5) from the dividend, add it to 114, then carry on: 1145 / 181

Moving on to step 8:
181 goes into 1145 6 times with a remainder of 59.
Write down 6 as next digit of the result. 
Result so far: 222936.0
Subtract 1086 from 1145 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 9:
181 goes into 590 3 times with a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 222936.3
If we subtract 543 from 590, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 10:
If we divide 470 by 181, we get 2 and a remainder of 108.
The number 2 becomes the next digit in our result. 
Result so far: 222936.32
Deduct 362 from 470 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 11:
1080 divided by 181 is 5 with a remainder of 175.
Record the quotient 5 as the next digit in the result. 
Result so far: 222936.325
Deduct 905 from 1080 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Going ahead to step 12:
181 can be fit into 1750 9 times, resulting in a remainder of 121.
The next digit of our result is 9. 
Result so far: 222936.3259
The remainder is 121 after subtracting 1629 from 1750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Step 13:
181 can be fit into 1210 6 times, resulting in a remainder of 124.
Put 6 as the next digit of the answer. 
Result so far: 222936.32596
The remainder is 124 after subtracting 1086 from 1210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Going ahead to step 14:
181 goes into 1240 6 times with a remainder of 154.
Record the quotient 6 as the next digit in the result. 
Result so far: 222936.325966
If we take 1086 away from 1240, we end up with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

The final outcome is 222936.325966, with a leftover of 1.54e-05.
