259869 ÷ 83 
The aim is to understand the frequency of 83 in 259869.

On to step 1:
83 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 83

Advancing to step 2:
25 divided by 83 is 0 with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Take the next digit (9) from the dividend and append it to 25, then repeat: 259 / 83

Moving on to step 3:
259 divided by 83 is 3 with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 249 from 259 and we're left with 10.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 83

Let's proceed to step 4:
83 can be fit into 108 1 times, resulting in a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Subtract 83 from 108 to get 25.
Bring next digit (6) of the dividend behind the 25 and repeat the process: 256 / 83

Moving on to step 5:
If we divide 256 by 83, we get 3 and a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 313.0
The remainder is 7 after subtracting 249 from 256.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 83

On to step 6:
If we divide 79 by 83, we get 0 and a remainder of 79.
Record the quotient 0 as the next digit in the result. 
Result so far: 3130.0
Subtracting 0 from 79 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 7:
If we divide 790 by 83, we get 9 and a remainder of 43.
Write down 9 as next digit of the result. 
Result so far: 3130.9
Deduct 747 from 790 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 8:
83 can be fit into 430 5 times, resulting in a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 3130.95
If we take 415 away from 430, we end up 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 9:
When dividing 150 by 83, we get 1 with a remainder of 67.
Record the quotient 1 as the next digit in the result. 
Result so far: 3130.951
Deduct 83 from 150 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 10:
83 goes into 670 8 times with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 3130.9518
The remainder is 6 after subtracting 664 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 11:
60 divided by 83 is 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 3130.9518
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 12:
The number 83 fits into 600 7 times, leaving a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 3130.951807
If we subtract 581 from 600, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 13:
When dividing 190 by 83, we get 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 3130.9518072
Subtract 166 from 190 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 14:
The number 83 fits into 240 2 times, leaving a remainder of 74.
Write down 2 as next digit of the result. 
Result so far: 3130.95180722
If we subtract 166 from 240, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

The quotient of the division is 3130.95180722, and the remainder is 7.4e-08.
