We're dividing 863615 by 83 
The aim is to understand the frequency of 83 in 863615.

Going ahead to step 1:
The number 83 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 83

Let's proceed to step 2:
If we divide 86 by 83, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 3 after subtracting 83 from 86.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 83

Step 3:
33 divided by 83 is 0 with a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 33, we end up with 33.
Grab the next digit (6) from the dividend, add it to 33, then carry on: 336 / 83

Let's proceed to step 4:
336 divided by 83 is 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 104.0
Subtract 332 from 336 to get 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 83

Advancing to step 5:
41 divided by 83 is 0 with a remainder of 41.
Record the quotient 0 as the next digit in the result. 
Result so far: 1040.0
Subtract 0 from 41 to get 41.
Include the next digit (5) from the dividend after 41, then repeat: 415 / 83

Let's proceed to step 6:
415 divided by 83 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 10405.0
Subtracting 415 from 415 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
0 divided by 83 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 10405.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
The number 83 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10405.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 10405.0 with a remaining 0.0.
