Let's divide 40766210 by 181
The aim is to understand the frequency of 181 in 40766210.

On to step 1:
When dividing 4 by 181, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 181

Moving on to step 2:
If we divide 40 by 181, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Bring next digit (7) of the dividend behind the 40 and repeat the process: 407 / 181

Advancing to step 3:
If we divide 407 by 181, we get 2 and a remainder of 45.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 362 from 407 leaves us with 45.
Append the next digit (6) from the dividend to 45 and continue with: 456 / 181

On to step 4:
181 goes into 456 2 times with a remainder of 94.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Subtracting 362 from 456 leaves us with 94.
Fetch the next digit (6) from the dividend, attach it to 94 and continue: 946 / 181

Advancing to step 5:
When dividing 946 by 181, we get 5 with a remainder of 41.
The next digit of our result is 5. 
Result so far: 225.0
The remainder is 41 after subtracting 905 from 946.
Take the next digit (2) from the dividend and append it to 41, then repeat: 412 / 181

On to step 6:
181 can be fit into 412 2 times, resulting in a remainder of 50.
Record the quotient 2 as the next digit in the result. 
Result so far: 2252.0
Subtract 362 from 412 to get 50.
Grab the next digit (1) from the dividend, add it to 50, then carry on: 501 / 181

Advancing to step 7:
When dividing 501 by 181, we get 2 with a remainder of 139.
Put 2 as the next digit of the answer. 
Result so far: 22522.0
Subtracting 362 from 501 leaves us with 139.
Include the next digit (0) from the dividend after 139, then repeat: 1390 / 181

Going ahead to step 8:
If we divide 1390 by 181, we get 7 and a remainder of 123.
Put 7 as the next digit of the answer. 
Result so far: 225227.0
Subtracting 1267 from 1390 leaves us with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Moving on to step 9:
If we divide 1230 by 181, we get 6 and a remainder of 144.
The next digit of our result is 6. 
Result so far: 225227.6
If we take 1086 away from 1230, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 10:
1440 divided by 181 is 7 with a remainder of 173.
The next digit of our result is 7. 
Result so far: 225227.67
Deduct 1267 from 1440 and we're left with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Step 11:
1730 divided by 181 is 9 with a remainder of 101.
The number 9 becomes the next digit in our result. 
Result so far: 225227.679
Subtracting 1629 from 1730 leaves us with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

On to step 12:
The number 181 fits into 1010 5 times, leaving a remainder of 105.
Use 5 as the next digit of our solution. 
Result so far: 225227.6795
If we subtract 905 from 1010, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Moving on to step 13:
181 goes into 1050 5 times with a remainder of 145.
Put 5 as the next digit of the answer. 
Result so far: 225227.67955
Subtract 905 from 1050 to get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

The final result is 225227.67955 with a remainder of 0.000145.
