We're dividing 85283 by 71 
The aim is to understand the frequency of 71 in 85283.

Step 1:
8 divided by 71 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 71

On to step 2:
71 goes into 85 1 times with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 71 from 85 leaves us with 14.
Append the next digit (2) from the dividend to 14 and continue with: 142 / 71

On to step 3:
142 divided by 71 is 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 142 from 142 and we're left with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 71

Step 4:
When dividing 8 by 71, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 120.0
If we subtract 0 from 8, we get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 71

Advancing to step 5:
If we divide 83 by 71, we get 1 and a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1201.0
If we subtract 71 from 83, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 6:
When dividing 120 by 71, we get 1 with a remainder of 49.
The next digit of our result is 1. 
Result so far: 1201.1
Subtract 71 from 120 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 7:
490 divided by 71 is 6 with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 1201.16
If we subtract 426 from 490, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 8:
The number 71 fits into 640 9 times, leaving a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 1201.169
Deduct 639 from 640 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
The number 71 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 1201.169
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
71 goes into 100 1 times with a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 1201.16901
Subtracting 71 from 100 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 11:
If we divide 290 by 71, we get 4 and a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 1201.169014
Subtract 284 from 290 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 12:
If we divide 60 by 71, we get 0 and a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 1201.169014
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 13:
If we divide 600 by 71, we get 8 and a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 1201.16901408
If we subtract 568 from 600, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 1201.16901408 and a remainder of 3.2e-08.
