We're dividing 21180132 by 71 
The aim is to understand the frequency of 71 in 21180132.

Going ahead to step 1:
If we divide 2 by 71, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 71

On to step 2:
71 can be fit into 21 0 times, resulting in a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 71

Advancing to step 3:
71 can be fit into 211 2 times, resulting in a remainder of 69.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 142 from 211 leaves us with 69.
Include the next digit (8) from the dividend after 69, then repeat: 698 / 71

Advancing to step 4:
If we divide 698 by 71, we get 9 and a remainder of 59.
Put 9 as the next digit of the answer. 
Result so far: 29.0
The remainder is 59 after subtracting 639 from 698.
Take the next digit (0) from the dividend and append it to 59, then repeat: 590 / 71

Advancing to step 5:
71 goes into 590 8 times with a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 298.0
Subtract 568 from 590 to get 22.
Bring next digit (1) of the dividend behind the 22 and repeat the process: 221 / 71

Step 6:
221 divided by 71 is 3 with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 2983.0
Subtracting 213 from 221 leaves us with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 71

Going ahead to step 7:
If we divide 83 by 71, we get 1 and a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 29831.0
The remainder is 12 after subtracting 71 from 83.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 71

Moving on to step 8:
If we divide 122 by 71, we get 1 and a remainder of 51.
Use 1 as the next digit of our solution. 
Result so far: 298311.0
If we take 71 away from 122, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 9:
When dividing 510 by 71, we get 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 298311.7
If we take 497 away from 510, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 10:
71 goes into 130 1 times with a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 298311.71
Subtract 71 from 130 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 11:
71 goes into 590 8 times with a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 298311.718
If we subtract 568 from 590, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 12:
220 divided by 71 is 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 298311.7183
Subtract 213 from 220 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 13:
71 goes into 70 0 times with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 298311.7183
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 14:
71 can be fit into 700 9 times, resulting in a remainder of 61.
Record the quotient 9 as the next digit in the result. 
Result so far: 298311.718309
Deduct 639 from 700 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 15:
If we divide 610 by 71, we get 8 and a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 298311.7183098
If we take 568 away from 610, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 16:
71 can be fit into 420 5 times, resulting in a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 298311.71830985
Subtract 355 from 420 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Our division results in 298311.71830985 with a remaining 6.5e-08.
