521677 ÷ 71 
The aim is to understand the frequency of 71 in 521677.

On to step 1:
71 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 71

Moving on to step 2:
71 can be fit into 52 0 times, resulting in a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 52 after subtracting 0 from 52.
Take the next digit (1) from the dividend and append it to 52, then repeat: 521 / 71

On to step 3:
71 goes into 521 7 times with a remainder of 24.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 497 from 521, we get 24.
Take the next digit (6) from the dividend and append it to 24, then repeat: 246 / 71

On to step 4:
71 can be fit into 246 3 times, resulting in a remainder of 33.
The next digit of our result is 3. 
Result so far: 73.0
If we subtract 213 from 246, we get 33.
Grab the next digit (7) from the dividend, add it to 33, then carry on: 337 / 71

Step 5:
If we divide 337 by 71, we get 4 and a remainder of 53.
Use 4 as the next digit of our solution. 
Result so far: 734.0
If we take 284 away from 337, we end up with 53.
Fetch the next digit (7) from the dividend, attach it to 53 and continue: 537 / 71

On to step 6:
When dividing 537 by 71, we get 7 with a remainder of 40.
The next digit of our result is 7. 
Result so far: 7347.0
The remainder is 40 after subtracting 497 from 537.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 7:
71 can be fit into 400 5 times, resulting in a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 7347.5
Subtract 355 from 400 to get 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 8:
450 divided by 71 is 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 7347.56
If we subtract 426 from 450, we get 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 9:
71 goes into 240 3 times with a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 7347.563
If we subtract 213 from 240, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 10:
The number 71 fits into 270 3 times, leaving a remainder of 57.
Record the quotient 3 as the next digit in the result. 
Result so far: 7347.5633
Subtract 213 from 270 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

The final result is 7347.5633 with a remainder of 0.00057.
