981988 ÷ 71 
The aim is to understand the frequency of 71 in 981988.

Advancing to step 1:
71 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 71

Step 2:
When dividing 98 by 71, we get 1 with a remainder of 27.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 27 after subtracting 71 from 98.
Grab the next digit (1) from the dividend, add it to 27, then carry on: 271 / 71

On to step 3:
71 can be fit into 271 3 times, resulting in a remainder of 58.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 213 from 271 leaves us with 58.
Fetch the next digit (9) from the dividend, attach it to 58 and continue: 589 / 71

Let's proceed to step 4:
71 can be fit into 589 8 times, resulting in a remainder of 21.
Record the quotient 8 as the next digit in the result. 
Result so far: 138.0
The remainder is 21 after subtracting 568 from 589.
Bring next digit (8) of the dividend behind the 21 and repeat the process: 218 / 71

Step 5:
71 can be fit into 218 3 times, resulting in a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 1383.0
Subtract 213 from 218 to get 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 71

Let's proceed to step 6:
71 can be fit into 58 0 times, resulting in a remainder of 58.
The number 0 becomes the next digit in our result. 
Result so far: 13830.0
If we take 0 away from 58, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 7:
71 can be fit into 580 8 times, resulting in a remainder of 12.
The next digit of our result is 8. 
Result so far: 13830.8
Deduct 568 from 580 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 8:
When dividing 120 by 71, we get 1 with a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 13830.81
The remainder is 49 after subtracting 71 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 9:
When dividing 490 by 71, we get 6 with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 13830.816
The remainder is 64 after subtracting 426 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 10:
The number 71 fits into 640 9 times, leaving a remainder of 1.
The next digit of our result is 9. 
Result so far: 13830.8169
The remainder is 1 after subtracting 639 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 11:
10 divided by 71 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 13830.8169
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
71 goes into 100 1 times with a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 13830.816901
Subtracting 71 from 100 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 13:
290 divided by 71 is 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 13830.8169014
Subtract 284 from 290 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 14:
When dividing 60 by 71, we get 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 13830.8169014
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 13830.8169014 with a remainder of 6e-08.
