We're dividing 83491481 by 71 
The aim is to understand the frequency of 71 in 83491481.

Advancing to step 1:
71 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 71

Advancing to step 2:
When dividing 83 by 71, we get 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 71 from 83 to get 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 71

Step 3:
71 goes into 124 1 times with a remainder of 53.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 71 from 124, we get 53.
Grab the next digit (9) from the dividend, add it to 53, then carry on: 539 / 71

Moving on to step 4:
The number 71 fits into 539 7 times, leaving a remainder of 42.
Write down 7 as next digit of the result. 
Result so far: 117.0
Subtract 497 from 539 to get 42.
Take the next digit (1) from the dividend and append it to 42, then repeat: 421 / 71

On to step 5:
The number 71 fits into 421 5 times, leaving a remainder of 66.
Record the quotient 5 as the next digit in the result. 
Result so far: 1175.0
Subtract 355 from 421 to get 66.
Fetch the next digit (4) from the dividend, attach it to 66 and continue: 664 / 71

On to step 6:
664 divided by 71 is 9 with a remainder of 25.
Record the quotient 9 as the next digit in the result. 
Result so far: 11759.0
If we subtract 639 from 664, we get 25.
Include the next digit (8) from the dividend after 25, then repeat: 258 / 71

Step 7:
When dividing 258 by 71, we get 3 with a remainder of 45.
Use 3 as the next digit of our solution. 
Result so far: 117593.0
If we take 213 away from 258, we end up with 45.
Take the next digit (1) from the dividend and append it to 45, then repeat: 451 / 71

Advancing to step 8:
71 can be fit into 451 6 times, resulting in a remainder of 25.
Put 6 as the next digit of the answer. 
Result so far: 1175936.0
Deduct 426 from 451 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 9:
71 goes into 250 3 times with a remainder of 37.
The next digit of our result is 3. 
Result so far: 1175936.3
Deduct 213 from 250 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 10:
71 can be fit into 370 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 1175936.35
The remainder is 15 after subtracting 355 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 11:
71 can be fit into 150 2 times, resulting in a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 1175936.352
If we take 142 away from 150, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 12:
When dividing 80 by 71, we get 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1175936.3521
If we take 71 away from 80, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 13:
The number 71 fits into 90 1 times, leaving a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 1175936.35211
Subtract 71 from 90 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final outcome is 1175936.35211, with a leftover of 1.9e-05.
