We divide 869070 by 71
The aim is to understand the frequency of 71 in 869070.

Step 1:
If we divide 8 by 71, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 71

Step 2:
71 goes into 86 1 times with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 71 away from 86, we end up with 15.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 71

Going ahead to step 3:
When dividing 159 by 71, we get 2 with a remainder of 17.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 142 from 159 and we're left with 17.
Append the next digit (0) from the dividend to 17 and continue with: 170 / 71

Moving on to step 4:
71 goes into 170 2 times with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 122.0
Subtracting 142 from 170 leaves us with 28.
Grab the next digit (7) from the dividend, add it to 28, then carry on: 287 / 71

Step 5:
The number 71 fits into 287 4 times, leaving a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 1224.0
Deduct 284 from 287 and we're left with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 71

Moving on to step 6:
71 goes into 30 0 times with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 12240.0
If we take 0 away from 30, we end up 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.

Moving on to step 7:
If we divide 300 by 71, we get 4 and a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 12240.4
If we subtract 284 from 300, we 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.

On to step 8:
The number 71 fits into 160 2 times, leaving a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 12240.42
If we subtract 142 from 160, we get 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 9:
If we divide 180 by 71, we get 2 and a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 12240.422
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.

The quotient of the division is 12240.422, and the remainder is 0.0038.
