Let's divide 838524 by 71
The aim is to understand the frequency of 71 in 838524.

Moving on to step 1:
When dividing 8 by 71, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 71

Step 2:
The number 71 fits into 83 1 times, leaving a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 71 from 83 to get 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 71

Going ahead to step 3:
When dividing 128 by 71, we get 1 with a remainder of 57.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 71 from 128 leaves us with 57.
Append the next digit (5) from the dividend to 57 and continue with: 575 / 71

Moving on to step 4:
When dividing 575 by 71, we get 8 with a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 118.0
Deduct 568 from 575 and we're left with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 71

Going ahead to step 5:
71 goes into 72 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1181.0
If we subtract 71 from 72, we get 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 71

Going ahead to step 6:
71 can be fit into 14 0 times, resulting in a remainder of 14.
The next digit of our result is 0. 
Result so far: 11810.0
Deduct 0 from 14 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
If we divide 140 by 71, we get 1 and a remainder of 69.
Use 1 as the next digit of our solution. 
Result so far: 11810.1
If we subtract 71 from 140, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 8:
If we divide 690 by 71, we get 9 and a remainder of 51.
Record the quotient 9 as the next digit in the result. 
Result so far: 11810.19
If we subtract 639 from 690, we get 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:
If we divide 510 by 71, we get 7 and a remainder of 13.
The next digit of our result is 7. 
Result so far: 11810.197
Deduct 497 from 510 and we're left 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.

On to step 10:
71 goes into 130 1 times with a remainder of 59.
Put 1 as the next digit of the answer. 
Result so far: 11810.1971
Deduct 71 from 130 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 11:
When dividing 590 by 71, we get 8 with a remainder of 22.
The next digit of our result is 8. 
Result so far: 11810.19718
Deduct 568 from 590 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 12:
When dividing 220 by 71, we get 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 11810.197183
Deduct 213 from 220 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 13:
If we divide 70 by 71, we get 0 and a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 11810.197183
Subtract 0 from 70 to get 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:
If we divide 700 by 71, we get 9 and a remainder of 61.
Put 9 as the next digit of the answer. 
Result so far: 11810.19718309
Subtracting 639 from 700 leaves us 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.

The final outcome is 11810.19718309, with a leftover of 6.1e-08.
