We divide 21153871 by 271
The aim is to understand the frequency of 271 in 21153871.

Step 1:
When dividing 2 by 271, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 271

Let's proceed to step 2:
21 divided by 271 is 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Take the next digit (1) from the dividend and append it to 21, then repeat: 211 / 271

Let's proceed to step 3:
271 can be fit into 211 0 times, resulting in a remainder of 211.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 211 and we're left with 211.
Grab the next digit (5) from the dividend, add it to 211, then carry on: 2115 / 271

Let's proceed to step 4:
The number 271 fits into 2115 7 times, leaving a remainder of 218.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 1897 from 2115 leaves us with 218.
Take the next digit (3) from the dividend and append it to 218, then repeat: 2183 / 271

On to step 5:
When dividing 2183 by 271, we get 8 with a remainder of 15.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
If we take 2168 away from 2183, we end up with 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 271

On to step 6:
271 goes into 158 0 times with a remainder of 158.
The number 0 becomes the next digit in our result. 
Result so far: 780.0
If we subtract 0 from 158, we get 158.
Bring next digit (7) of the dividend behind the 158 and repeat the process: 1587 / 271

Let's proceed to step 7:
271 can be fit into 1587 5 times, resulting in a remainder of 232.
Put 5 as the next digit of the answer. 
Result so far: 7805.0
Subtract 1355 from 1587 to get 232.
Take the next digit (1) from the dividend and append it to 232, then repeat: 2321 / 271

Going ahead to step 8:
If we divide 2321 by 271, we get 8 and a remainder of 153.
Record the quotient 8 as the next digit in the result. 
Result so far: 78058.0
If we subtract 2168 from 2321, we get 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

On to step 9:
271 goes into 1530 5 times with a remainder of 175.
The number 5 becomes the next digit in our result. 
Result so far: 78058.5
If we subtract 1355 from 1530, we get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

On to step 10:
271 can be fit into 1750 6 times, resulting in a remainder of 124.
Write down 6 as next digit of the result. 
Result so far: 78058.56
If we take 1626 away from 1750, we end up with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 11:
When dividing 1240 by 271, we get 4 with a remainder of 156.
The next digit of our result is 4. 
Result so far: 78058.564
If we take 1084 away from 1240, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Advancing to step 12:
271 goes into 1560 5 times with a remainder of 205.
Record the quotient 5 as the next digit in the result. 
Result so far: 78058.5645
Subtract 1355 from 1560 to get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Let's proceed to step 13:
271 can be fit into 2050 7 times, resulting in a remainder of 153.
Write down 7 as next digit of the result. 
Result so far: 78058.56457
The remainder is 153 after subtracting 1897 from 2050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Moving on to step 14:
1530 divided by 271 is 5 with a remainder of 175.
The next digit of our result is 5. 
Result so far: 78058.564575
Deduct 1355 from 1530 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.

On to step 15:
When dividing 1750 by 271, we get 6 with a remainder of 124.
Use 6 as the next digit of our solution. 
Result so far: 78058.5645756
Subtract 1626 from 1750 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Step 16:
1240 divided by 271 is 4 with a remainder of 156.
The number 4 becomes the next digit in our result. 
Result so far: 78058.56457564
If we subtract 1084 from 1240, we get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

In conclusion, the division gives 78058.56457564 with a balance of 1.56e-07.
