251078 ÷ 71 
The aim is to understand the frequency of 71 in 251078.

Going ahead to step 1:
The number 71 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 71

On to step 2:
If we divide 25 by 71, we get 0 and a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Append the next digit (1) from the dividend to 25 and continue with: 251 / 71

Let's proceed to step 3:
When dividing 251 by 71, we get 3 with a remainder of 38.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 213 from 251 to get 38.
Append the next digit (0) from the dividend to 38 and continue with: 380 / 71

Moving on to step 4:
The number 71 fits into 380 5 times, leaving a remainder of 25.
The next digit of our result is 5. 
Result so far: 35.0
Subtracting 355 from 380 leaves us with 25.
Take the next digit (7) from the dividend and append it to 25, then repeat: 257 / 71

Let's proceed to step 5:
When dividing 257 by 71, we get 3 with a remainder of 44.
The number 3 becomes the next digit in our result. 
Result so far: 353.0
Subtracting 213 from 257 leaves us with 44.
Take the next digit (8) from the dividend and append it to 44, then repeat: 448 / 71

On to step 6:
When dividing 448 by 71, we get 6 with a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 3536.0
Deduct 426 from 448 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 7:
71 can be fit into 220 3 times, resulting in a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 3536.3
The remainder is 7 after subtracting 213 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 8:
70 divided by 71 is 0 with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 3536.3
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 9:
If we divide 700 by 71, we get 9 and a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 3536.309
Subtracting 639 from 700 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 10:
71 can be fit into 610 8 times, resulting in a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 3536.3098
Subtract 568 from 610 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 11:
When dividing 420 by 71, we get 5 with a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 3536.30985
Deduct 355 from 420 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 12:
When dividing 650 by 71, we get 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 3536.309859
If we subtract 639 from 650, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 13:
The number 71 fits into 110 1 times, leaving a remainder of 39.
The next digit of our result is 1. 
Result so far: 3536.3098591
Deduct 71 from 110 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 14:
If we divide 390 by 71, we get 5 and a remainder of 35.
The next digit of our result is 5. 
Result so far: 3536.30985915
If we subtract 355 from 390, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The quotient of the division is 3536.30985915, and the remainder is 3.5e-08.
