90159578 divided by 271 
The aim is to understand the frequency of 271 in 90159578.

Advancing to step 1:
When dividing 9 by 271, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 271

Advancing to step 2:
271 goes into 90 0 times with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Grab the next digit (1) from the dividend, add it to 90, then carry on: 901 / 271

Step 3:
When dividing 901 by 271, we get 3 with a remainder of 88.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 88 after subtracting 813 from 901.
Fetch the next digit (5) from the dividend, attach it to 88 and continue: 885 / 271

Step 4:
If we divide 885 by 271, we get 3 and a remainder of 72.
The next digit of our result is 3. 
Result so far: 33.0
Subtract 813 from 885 to get 72.
Fetch the next digit (9) from the dividend, attach it to 72 and continue: 729 / 271

Let's proceed to step 5:
The number 271 fits into 729 2 times, leaving a remainder of 187.
The number 2 becomes the next digit in our result. 
Result so far: 332.0
Subtract 542 from 729 to get 187.
Include the next digit (5) from the dividend after 187, then repeat: 1875 / 271

Going ahead to step 6:
The number 271 fits into 1875 6 times, leaving a remainder of 249.
Put 6 as the next digit of the answer. 
Result so far: 3326.0
If we subtract 1626 from 1875, we get 249.
Take the next digit (7) from the dividend and append it to 249, then repeat: 2497 / 271

Advancing to step 7:
271 goes into 2497 9 times with a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 33269.0
If we subtract 2439 from 2497, we get 58.
Take the next digit (8) from the dividend and append it to 58, then repeat: 588 / 271

Moving on to step 8:
The number 271 fits into 588 2 times, leaving a remainder of 46.
Put 2 as the next digit of the answer. 
Result so far: 332692.0
Deduct 542 from 588 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 9:
271 goes into 460 1 times with a remainder of 189.
The number 1 becomes the next digit in our result. 
Result so far: 332692.1
Subtract 271 from 460 to get 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Let's proceed to step 10:
The number 271 fits into 1890 6 times, leaving a remainder of 264.
The number 6 becomes the next digit in our result. 
Result so far: 332692.16
Subtracting 1626 from 1890 leaves us with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Step 11:
271 can be fit into 2640 9 times, resulting in a remainder of 201.
Use 9 as the next digit of our solution. 
Result so far: 332692.169
If we take 2439 away from 2640, we end up with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Going ahead to step 12:
If we divide 2010 by 271, we get 7 and a remainder of 113.
Write down 7 as next digit of the result. 
Result so far: 332692.1697
Subtracting 1897 from 2010 leaves us with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

On to step 13:
271 can be fit into 1130 4 times, resulting in a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 332692.16974
Subtracting 1084 from 1130 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 14:
The number 271 fits into 460 1 times, leaving a remainder of 189.
Use 1 as the next digit of our solution. 
Result so far: 332692.169741
If we take 271 away from 460, we end up with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

On to step 15:
271 goes into 1890 6 times with a remainder of 264.
The number 6 becomes the next digit in our result. 
Result so far: 332692.1697416
Subtracting 1626 from 1890 leaves us with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Step 16:
When dividing 2640 by 271, we get 9 with a remainder of 201.
Use 9 as the next digit of our solution. 
Result so far: 332692.16974169
Subtracting 2439 from 2640 leaves us with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

The quotient of the division is 332692.16974169, and the remainder is 2.01e-07.
