583728 divided by 71 
The aim is to understand the frequency of 71 in 583728.

On to step 1:
5 divided by 71 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 71

Step 2:
58 divided by 71 is 0 with a remainder of 58.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 58 leaves us with 58.
Include the next digit (3) from the dividend after 58, then repeat: 583 / 71

Going ahead to step 3:
71 goes into 583 8 times with a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 568 from 583 to get 15.
Grab the next digit (7) from the dividend, add it to 15, then carry on: 157 / 71

Step 4:
71 goes into 157 2 times with a remainder of 15.
The next digit of our result is 2. 
Result so far: 82.0
Deduct 142 from 157 and we're left with 15.
Include the next digit (2) from the dividend after 15, then repeat: 152 / 71

On to step 5:
71 goes into 152 2 times with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 822.0
Deduct 142 from 152 and we're left with 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 71

Advancing to step 6:
The number 71 fits into 108 1 times, leaving a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 8221.0
If we take 71 away from 108, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 7:
If we divide 370 by 71, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 8221.5
Subtracting 355 from 370 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
150 divided by 71 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 8221.52
The remainder is 8 after subtracting 142 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
If we divide 80 by 71, we get 1 and a remainder of 9.
The next digit of our result is 1. 
Result so far: 8221.521
Subtracting 71 from 80 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 10:
90 divided by 71 is 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 8221.5211
If we take 71 away from 90, we end up 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.

The quotient of the division is 8221.5211, and the remainder is 0.00019.
