We're dividing 847900 by 71 
The aim is to understand the frequency of 71 in 847900.

On to step 1:
8 divided by 71 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 71

On to step 2:
71 can be fit into 84 1 times, resulting in a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 71 from 84 leaves us with 13.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 71

Advancing to step 3:
If we divide 137 by 71, we get 1 and a remainder of 66.
The next digit of our result is 1. 
Result so far: 11.0
Deduct 71 from 137 and we're left with 66.
Take the next digit (9) from the dividend and append it to 66, then repeat: 669 / 71

Step 4:
When dividing 669 by 71, we get 9 with a remainder of 30.
Put 9 as the next digit of the answer. 
Result so far: 119.0
The remainder is 30 after subtracting 639 from 669.
Fetch the next digit (0) from the dividend, attach it to 30 and continue: 300 / 71

On to step 5:
300 divided by 71 is 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 1194.0
If we subtract 284 from 300, we get 16.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 71

On to step 6:
71 can be fit into 160 2 times, resulting in a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 11942.0
Deduct 142 from 160 and we're left 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.

On to step 7:
180 divided by 71 is 2 with a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 11942.2
If we subtract 142 from 180, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 8:
When dividing 380 by 71, we get 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 11942.25
Subtract 355 from 380 to get 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 can be fit into 250 3 times, resulting in a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 11942.253
Subtracting 213 from 250 leaves us 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.

Step 10:
The number 71 fits into 370 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 11942.2535
If we subtract 355 from 370, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 11:
150 divided by 71 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 11942.25352
Subtract 142 from 150 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
71 goes into 80 1 times with a remainder of 9.
The next digit of our result is 1. 
Result so far: 11942.253521
If we subtract 71 from 80, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 13:
71 goes into 90 1 times with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 11942.2535211
Subtracting 71 from 90 leaves us 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 quotient of the division is 11942.2535211, and the remainder is 1.9e-07.
