Let's divide 40527830 by 291
The aim is to understand the frequency of 291 in 40527830.

On to step 1:
When dividing 4 by 291, 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.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 291

Moving on to step 2:
If we divide 40 by 291, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Append the next digit (5) from the dividend to 40 and continue with: 405 / 291

Going ahead to step 3:
If we divide 405 by 291, we get 1 and a remainder of 114.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 291 from 405 and we're left with 114.
Fetch the next digit (2) from the dividend, attach it to 114 and continue: 1142 / 291

On to step 4:
291 can be fit into 1142 3 times, resulting in a remainder of 269.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we subtract 873 from 1142, we get 269.
Append the next digit (7) from the dividend to 269 and continue with: 2697 / 291

On to step 5:
The number 291 fits into 2697 9 times, leaving a remainder of 78.
Use 9 as the next digit of our solution. 
Result so far: 139.0
Subtract 2619 from 2697 to get 78.
Take the next digit (8) from the dividend and append it to 78, then repeat: 788 / 291

Going ahead to step 6:
291 goes into 788 2 times with a remainder of 206.
Put 2 as the next digit of the answer. 
Result so far: 1392.0
Deduct 582 from 788 and we're left with 206.
Bring next digit (3) of the dividend behind the 206 and repeat the process: 2063 / 291

Going ahead to step 7:
2063 divided by 291 is 7 with a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 13927.0
Subtracting 2037 from 2063 leaves us with 26.
Bring next digit (0) of the dividend behind the 26 and repeat the process: 260 / 291

Moving on to step 8:
The number 291 fits into 260 0 times, leaving a remainder of 260.
Put 0 as the next digit of the answer. 
Result so far: 139270.0
If we subtract 0 from 260, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 9:
When dividing 2600 by 291, we get 8 with a remainder of 272.
Write down 8 as next digit of the result. 
Result so far: 139270.8
If we take 2328 away from 2600, we end up with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Going ahead to step 10:
The number 291 fits into 2720 9 times, leaving a remainder of 101.
Write down 9 as next digit of the result. 
Result so far: 139270.89
If we take 2619 away from 2720, we end up 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.

Advancing to step 11:
When dividing 1010 by 291, we get 3 with a remainder of 137.
Write down 3 as next digit of the result. 
Result so far: 139270.893
The remainder is 137 after subtracting 873 from 1010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Step 12:
When dividing 1370 by 291, we get 4 with a remainder of 206.
Use 4 as the next digit of our solution. 
Result so far: 139270.8934
If we take 1164 away from 1370, we end up with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Let's proceed to step 13:
291 goes into 2060 7 times with a remainder of 23.
The next digit of our result is 7. 
Result so far: 139270.89347
If we subtract 2037 from 2060, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 14:
291 goes into 230 0 times with a remainder of 230.
Write down 0 as next digit of the result. 
Result so far: 139270.89347
Deduct 0 from 230 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 15:
The number 291 fits into 2300 7 times, leaving a remainder of 263.
The number 7 becomes the next digit in our result. 
Result so far: 139270.8934707
If we subtract 2037 from 2300, we get 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Advancing to step 16:
When dividing 2630 by 291, we get 9 with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 139270.89347079
Subtracting 2619 from 2630 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Our division results in 139270.89347079 with a remaining 1.1e-08.
