973802 divided by 71 
The aim is to understand the frequency of 71 in 973802.

Step 1:
If we divide 9 by 71, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 71

Step 2:
When dividing 97 by 71, we get 1 with a remainder of 26.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 71 from 97 and we're left with 26.
Take the next digit (3) from the dividend and append it to 26, then repeat: 263 / 71

Step 3:
When dividing 263 by 71, we get 3 with a remainder of 50.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 213 from 263 leaves us with 50.
Bring next digit (8) of the dividend behind the 50 and repeat the process: 508 / 71

Advancing to step 4:
If we divide 508 by 71, we get 7 and a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 137.0
Subtracting 497 from 508 leaves us with 11.
Grab the next digit (0) from the dividend, add it to 11, then carry on: 110 / 71

Moving on to step 5:
110 divided by 71 is 1 with a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 1371.0
Deduct 71 from 110 and we're left with 39.
Grab the next digit (2) from the dividend, add it to 39, then carry on: 392 / 71

Moving on to step 6:
If we divide 392 by 71, we get 5 and a remainder of 37.
Write down 5 as next digit of the result. 
Result so far: 13715.0
The remainder is 37 after subtracting 355 from 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 7:
370 divided by 71 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 13715.5
Subtracting 355 from 370 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
71 can be fit into 150 2 times, resulting in a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 13715.52
The remainder is 8 after subtracting 142 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
71 goes into 80 1 times with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 13715.521
Deduct 71 from 80 and we're left 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.

Step 10:
When dividing 90 by 71, we get 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 13715.5211
Deduct 71 from 90 and we're left with 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 result is 13715.5211 with a remainder of 0.00019.
