Let's divide 866103 by 71
The aim is to understand the frequency of 71 in 866103.

Going ahead to step 1:
71 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 71

Step 2:
The number 71 fits into 86 1 times, leaving a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 71 from 86 leaves us with 15.
Take the next digit (6) from the dividend and append it to 15, then repeat: 156 / 71

Step 3:
71 goes into 156 2 times with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 142 from 156 and we're left with 14.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 71

Advancing to step 4:
If we divide 141 by 71, we get 1 and a remainder of 70.
Put 1 as the next digit of the answer. 
Result so far: 121.0
Subtract 71 from 141 to get 70.
Append the next digit (0) from the dividend to 70 and continue with: 700 / 71

On to step 5:
71 goes into 700 9 times with a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 1219.0
Subtract 639 from 700 to get 61.
Grab the next digit (3) from the dividend, add it to 61, then carry on: 613 / 71

Moving on to step 6:
71 can be fit into 613 8 times, resulting in a remainder of 45.
The number 8 becomes the next digit in our result. 
Result so far: 12198.0
Deduct 568 from 613 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 7:
71 goes into 450 6 times with a remainder of 24.
The next digit of our result is 6. 
Result so far: 12198.6
Deduct 426 from 450 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 8:
71 can be fit into 240 3 times, resulting in a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 12198.63
Deduct 213 from 240 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 9:
When dividing 270 by 71, we get 3 with a remainder of 57.
Use 3 as the next digit of our solution. 
Result so far: 12198.633
If we take 213 away from 270, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

The final outcome is 12198.633, with a leftover of 0.0057.
