We look at the division of 360612 by 71 
The aim is to understand the frequency of 71 in 360612.

Let's proceed to step 1:
If we divide 3 by 71, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 71

Let's proceed to step 2:
71 can be fit into 36 0 times, resulting in a remainder of 36.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 36 and we're left with 36.
Grab the next digit (0) from the dividend, add it to 36, then carry on: 360 / 71

On to step 3:
If we divide 360 by 71, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 355 from 360 leaves us with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 71

Let's proceed to step 4:
The number 71 fits into 56 0 times, leaving a remainder of 56.
Write down 0 as next digit of the result. 
Result so far: 50.0
The remainder is 56 after subtracting 0 from 56.
Append the next digit (1) from the dividend to 56 and continue with: 561 / 71

Going ahead to step 5:
The number 71 fits into 561 7 times, leaving a remainder of 64.
Record the quotient 7 as the next digit in the result. 
Result so far: 507.0
If we subtract 497 from 561, we get 64.
Bring next digit (2) of the dividend behind the 64 and repeat the process: 642 / 71

Step 6:
71 can be fit into 642 9 times, resulting in a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 5079.0
If we take 639 away from 642, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
71 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 5079.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
If we divide 300 by 71, we get 4 and a remainder of 16.
The next digit of our result is 4. 
Result so far: 5079.04
Subtracting 284 from 300 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
The number 71 fits into 160 2 times, leaving a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 5079.042
Subtract 142 from 160 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 10:
71 goes into 180 2 times with a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 5079.0422
The remainder is 38 after subtracting 142 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The quotient of the division is 5079.0422, and the remainder is 0.00038.
