Let's divide 66039453 by 71
The aim is to understand the frequency of 71 in 66039453.

Going ahead to step 1:
The number 71 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 71

Moving on to step 2:
66 divided by 71 is 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Include the next digit (0) from the dividend after 66, then repeat: 660 / 71

Step 3:
The number 71 fits into 660 9 times, leaving a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 639 from 660, we get 21.
Bring next digit (3) of the dividend behind the 21 and repeat the process: 213 / 71

Advancing to step 4:
When dividing 213 by 71, we get 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 93.0
Subtracting 213 from 213 leaves us with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 71

Advancing to step 5:
The number 71 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 930.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 71

Step 6:
71 goes into 94 1 times with a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 9301.0
Subtract 71 from 94 to get 23.
Bring next digit (5) of the dividend behind the 23 and repeat the process: 235 / 71

Step 7:
The number 71 fits into 235 3 times, leaving a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 93013.0
Subtracting 213 from 235 leaves us with 22.
Append the next digit (3) from the dividend to 22 and continue with: 223 / 71

On to step 8:
71 can be fit into 223 3 times, resulting in a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 930133.0
Subtract 213 from 223 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
71 can be fit into 100 1 times, resulting in a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 930133.1
Subtract 71 from 100 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 10:
71 can be fit into 290 4 times, resulting in a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 930133.14
Subtracting 284 from 290 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 11:
When dividing 60 by 71, we get 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 930133.14
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 12:
If we divide 600 by 71, we get 8 and a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 930133.1408
Subtract 568 from 600 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 13:
71 goes into 320 4 times with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 930133.14084
Deduct 284 from 320 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 14:
When dividing 360 by 71, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 930133.140845
Subtract 355 from 360 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 15:
The number 71 fits into 50 0 times, leaving a remainder of 50.
The next digit of our result is 0. 
Result so far: 930133.140845
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 16:
If we divide 500 by 71, we get 7 and a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 930133.14084507
Deduct 497 from 500 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Our division results in 930133.14084507 with a remaining 3e-09.
