989538 divided by 71 
The aim is to understand the frequency of 71 in 989538.

Let's proceed to step 1:
71 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 71

Let's proceed to step 2:
71 can be fit into 98 1 times, resulting in a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 71 from 98 and we're left with 27.
Fetch the next digit (9) from the dividend, attach it to 27 and continue: 279 / 71

Going ahead to step 3:
When dividing 279 by 71, we get 3 with a remainder of 66.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 213 from 279 and we're left with 66.
Append the next digit (5) from the dividend to 66 and continue with: 665 / 71

Advancing to step 4:
71 can be fit into 665 9 times, resulting in a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 139.0
Subtract 639 from 665 to get 26.
Append the next digit (3) from the dividend to 26 and continue with: 263 / 71

Going ahead to step 5:
263 divided by 71 is 3 with a remainder of 50.
Record the quotient 3 as the next digit in the result. 
Result so far: 1393.0
Subtract 213 from 263 to get 50.
Bring next digit (8) of the dividend behind the 50 and repeat the process: 508 / 71

Moving on to step 6:
If we divide 508 by 71, we get 7 and a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 13937.0
Deduct 497 from 508 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
If we divide 110 by 71, we get 1 and a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 13937.1
Subtracting 71 from 110 leaves us 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.

Step 8:
If we divide 390 by 71, we get 5 and a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 13937.15
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.

Let's proceed to step 9:
71 goes into 350 4 times with a remainder of 66.
Put 4 as the next digit of the answer. 
Result so far: 13937.154
Deduct 284 from 350 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 10:
When dividing 660 by 71, we get 9 with a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 13937.1549
If we subtract 639 from 660, 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.

Going ahead to step 11:
When dividing 210 by 71, we get 2 with a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 13937.15492
Deduct 142 from 210 and we're left with 68.
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 12:
680 divided by 71 is 9 with a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 13937.154929
Deduct 639 from 680 and we're left 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 13:
If we divide 410 by 71, we get 5 and a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 13937.1549295
If we subtract 355 from 410, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 14:
The number 71 fits into 550 7 times, leaving a remainder of 53.
Write down 7 as next digit of the result. 
Result so far: 13937.15492957
Subtracting 497 from 550 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

The final result is 13937.15492957 with a remainder of 5.3e-08.
