Let's divide 81857 by 71
The aim is to understand the frequency of 71 in 81857.

Advancing to step 1:
71 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 71

Going ahead to step 2:
The number 71 fits into 81 1 times, leaving a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 71 from 81 and we're left with 10.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 71

Step 3:
71 goes into 108 1 times with a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we subtract 71 from 108, we get 37.
Fetch the next digit (5) from the dividend, attach it to 37 and continue: 375 / 71

Going ahead to step 4:
375 divided by 71 is 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 115.0
Subtracting 355 from 375 leaves us with 20.
Bring next digit (7) of the dividend behind the 20 and repeat the process: 207 / 71

Going ahead to step 5:
207 divided by 71 is 2 with a remainder of 65.
Write down 2 as next digit of the result. 
Result so far: 1152.0
Subtract 142 from 207 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.

Moving on to step 6:
650 divided by 71 is 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 1152.9
Subtracting 639 from 650 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
If we divide 110 by 71, we get 1 and a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 1152.91
Deduct 71 from 110 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 8:
71 can be fit into 390 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 1152.915
Subtracting 355 from 390 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 9:
If we divide 350 by 71, we get 4 and a remainder of 66.
Write down 4 as next digit of the result. 
Result so far: 1152.9154
Deduct 284 from 350 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 10:
The number 71 fits into 660 9 times, leaving a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 1152.91549
Deduct 639 from 660 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 11:
71 goes into 210 2 times with a remainder of 68.
The next digit of our result is 2. 
Result so far: 1152.915492
Subtracting 142 from 210 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 12:
680 divided by 71 is 9 with a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 1152.9154929
Subtract 639 from 680 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 13:
71 can be fit into 410 5 times, resulting in a remainder of 55.
The next digit of our result is 5. 
Result so far: 1152.91549295
If we take 355 away from 410, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Our division results in 1152.91549295 with a remaining 5.5e-08.
