We look at the division of 87349 by 71 
The aim is to understand the frequency of 71 in 87349.

Going ahead to step 1:
71 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 71

Moving on to step 2:
The number 71 fits into 87 1 times, leaving a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 71 away from 87, we end up with 16.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 71

Going ahead to step 3:
71 can be fit into 163 2 times, resulting in a remainder of 21.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Deduct 142 from 163 and we're left with 21.
Fetch the next digit (4) from the dividend, attach it to 21 and continue: 214 / 71

Step 4:
The number 71 fits into 214 3 times, leaving a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 123.0
The remainder is 1 after subtracting 213 from 214.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 71

Advancing to step 5:
If we divide 19 by 71, we get 0 and a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 1230.0
Deduct 0 from 19 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 6:
If we divide 190 by 71, we get 2 and a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 1230.2
The remainder is 48 after subtracting 142 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 7:
If we divide 480 by 71, we get 6 and a remainder of 54.
Record the quotient 6 as the next digit in the result. 
Result so far: 1230.26
The remainder is 54 after subtracting 426 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 8:
The number 71 fits into 540 7 times, leaving a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 1230.267
Subtract 497 from 540 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 9:
430 divided by 71 is 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 1230.2676
Deduct 426 from 430 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
When dividing 40 by 71, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 1230.2676
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
The number 71 fits into 400 5 times, leaving a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 1230.267605
If we take 355 away from 400, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 12:
450 divided by 71 is 6 with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 1230.2676056
If we take 426 away from 450, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 13:
If we divide 240 by 71, we get 3 and a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 1230.26760563
Deduct 213 from 240 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The final outcome is 1230.26760563, with a leftover of 2.7e-08.
