858188 divided by 71 
The aim is to understand the frequency of 71 in 858188.

Advancing to step 1:
The number 71 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 71

Advancing to step 2:
85 divided by 71 is 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 71 from 85 to get 14.
Append the next digit (8) from the dividend to 14 and continue with: 148 / 71

Step 3:
71 goes into 148 2 times with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtracting 142 from 148 leaves us with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 71

On to step 4:
The number 71 fits into 61 0 times, leaving a remainder of 61.
Put 0 as the next digit of the answer. 
Result so far: 120.0
Subtracting 0 from 61 leaves us with 61.
Grab the next digit (8) from the dividend, add it to 61, then carry on: 618 / 71

Advancing to step 5:
If we divide 618 by 71, we get 8 and a remainder of 50.
Record the quotient 8 as the next digit in the result. 
Result so far: 1208.0
Subtract 568 from 618 to get 50.
Take the next digit (8) from the dividend and append it to 50, then repeat: 508 / 71

Let's proceed to step 6:
When dividing 508 by 71, we get 7 with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 12087.0
Subtract 497 from 508 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
71 can be fit into 110 1 times, resulting in a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 12087.1
If we subtract 71 from 110, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 8:
If we divide 390 by 71, we get 5 and a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 12087.15
The remainder is 35 after subtracting 355 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 9:
If we divide 350 by 71, we get 4 and a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 12087.154
Subtracting 284 from 350 leaves us 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 next digit of our result is 9. 
Result so far: 12087.1549
Subtracting 639 from 660 leaves us 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.

Moving on to step 11:
71 goes into 210 2 times with a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 12087.15492
Deduct 142 from 210 and we're left 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:
If we divide 680 by 71, we get 9 and a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 12087.154929
Deduct 639 from 680 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 13:
71 can be fit into 410 5 times, resulting in a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 12087.1549295
If we subtract 355 from 410, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 14:
The number 71 fits into 550 7 times, leaving a remainder of 53.
The number 7 becomes the next digit in our result. 
Result so far: 12087.15492957
If we take 497 away from 550, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

After the division, we end up with 12087.15492957 and a remainder of 5.3e-08.
