We look at the division of 673154 by 71 
The aim is to understand the frequency of 71 in 673154.

Moving on to step 1:
71 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 71

Let's proceed to step 2:
67 divided by 71 is 0 with a remainder of 67.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 67 to get 67.
Grab the next digit (3) from the dividend, add it to 67, then carry on: 673 / 71

Going ahead to step 3:
71 goes into 673 9 times with a remainder of 34.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 639 from 673 and we're left with 34.
Bring next digit (1) of the dividend behind the 34 and repeat the process: 341 / 71

Advancing to step 4:
When dividing 341 by 71, we get 4 with a remainder of 57.
The number 4 becomes the next digit in our result. 
Result so far: 94.0
Subtracting 284 from 341 leaves us with 57.
Grab the next digit (5) from the dividend, add it to 57, then carry on: 575 / 71

Moving on to step 5:
575 divided by 71 is 8 with a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 948.0
The remainder is 7 after subtracting 568 from 575.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 71

Let's proceed to step 6:
If we divide 74 by 71, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 9481.0
Subtracting 71 from 74 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
The number 71 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 9481.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
300 divided by 71 is 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 9481.04
Subtract 284 from 300 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
160 divided by 71 is 2 with a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 9481.042
If we take 142 away from 160, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 10:
71 can be fit into 180 2 times, resulting in a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 9481.0422
If we take 142 away from 180, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final result is 9481.0422 with a remainder of 0.00038.
