We divide 20526475 by 291
The aim is to understand the frequency of 291 in 20526475.

Advancing to step 1:
291 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 291

Let's proceed to step 2:
When dividing 20 by 291, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Include the next digit (5) from the dividend after 20, then repeat: 205 / 291

Moving on to step 3:
291 can be fit into 205 0 times, resulting in a remainder of 205.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 205 to get 205.
Include the next digit (2) from the dividend after 205, then repeat: 2052 / 291

Going ahead to step 4:
The number 291 fits into 2052 7 times, leaving a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 2037 from 2052, we get 15.
Include the next digit (6) from the dividend after 15, then repeat: 156 / 291

Step 5:
291 can be fit into 156 0 times, resulting in a remainder of 156.
The next digit of our result is 0. 
Result so far: 70.0
Subtract 0 from 156 to get 156.
Include the next digit (4) from the dividend after 156, then repeat: 1564 / 291

Moving on to step 6:
If we divide 1564 by 291, we get 5 and a remainder of 109.
Record the quotient 5 as the next digit in the result. 
Result so far: 705.0
Deduct 1455 from 1564 and we're left with 109.
Grab the next digit (7) from the dividend, add it to 109, then carry on: 1097 / 291

Step 7:
When dividing 1097 by 291, we get 3 with a remainder of 224.
The next digit of our result is 3. 
Result so far: 7053.0
If we take 873 away from 1097, we end up with 224.
Append the next digit (5) from the dividend to 224 and continue with: 2245 / 291

Advancing to step 8:
If we divide 2245 by 291, we get 7 and a remainder of 208.
The number 7 becomes the next digit in our result. 
Result so far: 70537.0
Deduct 2037 from 2245 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

On to step 9:
2080 divided by 291 is 7 with a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 70537.7
Subtracting 2037 from 2080 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 10:
When dividing 430 by 291, we get 1 with a remainder of 139.
Record the quotient 1 as the next digit in the result. 
Result so far: 70537.71
Subtract 291 from 430 to get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Let's proceed to step 11:
291 goes into 1390 4 times with a remainder of 226.
The next digit of our result is 4. 
Result so far: 70537.714
Subtract 1164 from 1390 to get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Advancing to step 12:
2260 divided by 291 is 7 with a remainder of 223.
The next digit of our result is 7. 
Result so far: 70537.7147
Subtracting 2037 from 2260 leaves us with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Going ahead to step 13:
If we divide 2230 by 291, we get 7 and a remainder of 193.
The number 7 becomes the next digit in our result. 
Result so far: 70537.71477
Subtracting 2037 from 2230 leaves us with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

After the division, we end up with 70537.71477 and a remainder of 0.000193.
