We're dividing 145784 by 71 
The aim is to understand the frequency of 71 in 145784.

Let's proceed to step 1:
71 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 71

Moving on to step 2:
71 goes into 14 0 times with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Grab the next digit (5) from the dividend, add it to 14, then carry on: 145 / 71

Advancing to step 3:
The number 71 fits into 145 2 times, leaving a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 142 from 145, we get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 71

Step 4:
When dividing 37 by 71, we get 0 with a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we subtract 0 from 37, we get 37.
Take the next digit (8) from the dividend and append it to 37, then repeat: 378 / 71

Advancing to step 5:
378 divided by 71 is 5 with a remainder of 23.
Write down 5 as next digit of the result. 
Result so far: 205.0
Subtract 355 from 378 to get 23.
Grab the next digit (4) from the dividend, add it to 23, then carry on: 234 / 71

Step 6:
234 divided by 71 is 3 with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 2053.0
If we subtract 213 from 234, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 7:
If we divide 210 by 71, we get 2 and a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 2053.2
The remainder is 68 after subtracting 142 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 8:
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: 2053.29
If we take 639 away from 680, we end up 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.

Step 9:
410 divided by 71 is 5 with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 2053.295
The remainder is 55 after subtracting 355 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 10:
71 goes into 550 7 times with a remainder of 53.
Write down 7 as next digit of the result. 
Result so far: 2053.2957
The remainder is 53 after subtracting 497 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 11:
71 goes into 530 7 times with a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 2053.29577
Subtract 497 from 530 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

After the division, we end up with 2053.29577 and a remainder of 3.3e-05.
