Let's divide 51355782 by 71
The aim is to understand the frequency of 71 in 51355782.

Moving on to step 1:
If we divide 5 by 71, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 71

On to step 2:
If we divide 51 by 71, we get 0 and a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Include the next digit (3) from the dividend after 51, then repeat: 513 / 71

Going ahead to step 3:
The number 71 fits into 513 7 times, leaving a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 497 from 513, we get 16.
Include the next digit (5) from the dividend after 16, then repeat: 165 / 71

Advancing to step 4:
If we divide 165 by 71, we get 2 and a remainder of 23.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
Deduct 142 from 165 and we're left with 23.
Bring next digit (5) of the dividend behind the 23 and repeat the process: 235 / 71

On to step 5:
If we divide 235 by 71, we get 3 and a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 723.0
If we subtract 213 from 235, we get 22.
Take the next digit (7) from the dividend and append it to 22, then repeat: 227 / 71

Step 6:
When dividing 227 by 71, we get 3 with a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 7233.0
Subtracting 213 from 227 leaves us with 14.
Grab the next digit (8) from the dividend, add it to 14, then carry on: 148 / 71

On to step 7:
71 goes into 148 2 times with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 72332.0
If we take 142 away from 148, we end up with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 71

Moving on to step 8:
71 goes into 62 0 times with a remainder of 62.
Record the quotient 0 as the next digit in the result. 
Result so far: 723320.0
Subtract 0 from 62 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 9:
71 goes into 620 8 times with a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 723320.8
If we take 568 away from 620, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 10:
520 divided by 71 is 7 with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 723320.87
Deduct 497 from 520 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 11:
If we divide 230 by 71, we get 3 and a remainder of 17.
The next digit of our result is 3. 
Result so far: 723320.873
Subtract 213 from 230 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 12:
The number 71 fits into 170 2 times, leaving a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 723320.8732
Subtract 142 from 170 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 13:
The number 71 fits into 280 3 times, leaving a remainder of 67.
Write down 3 as next digit of the result. 
Result so far: 723320.87323
If we subtract 213 from 280, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 14:
670 divided by 71 is 9 with a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 723320.873239
Subtracting 639 from 670 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 15:
If we divide 310 by 71, we get 4 and a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 723320.8732394
Subtracting 284 from 310 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 16:
260 divided by 71 is 3 with a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 723320.87323943
If we take 213 away from 260, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The final outcome is 723320.87323943, with a leftover of 4.7e-08.
