We're dividing 154660 by 83 
The aim is to understand the frequency of 83 in 154660.

Moving on to step 1:
The number 83 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 83

Let's proceed to step 2:
83 can be fit into 15 0 times, resulting in a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Fetch the next digit (4) from the dividend, attach it to 15 and continue: 154 / 83

Going ahead to step 3:
83 goes into 154 1 times with a remainder of 71.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 83 from 154, we get 71.
Take the next digit (6) from the dividend and append it to 71, then repeat: 716 / 83

Advancing to step 4:
716 divided by 83 is 8 with a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we subtract 664 from 716, we get 52.
Fetch the next digit (6) from the dividend, attach it to 52 and continue: 526 / 83

Let's proceed to step 5:
526 divided by 83 is 6 with a remainder of 28.
The next digit of our result is 6. 
Result so far: 186.0
Deduct 498 from 526 and we're left with 28.
Bring next digit (0) of the dividend behind the 28 and repeat the process: 280 / 83

Moving on to step 6:
The number 83 fits into 280 3 times, leaving a remainder of 31.
Record the quotient 3 as the next digit in the result. 
Result so far: 1863.0
If we take 249 away from 280, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 7:
83 goes into 310 3 times with a remainder of 61.
Use 3 as the next digit of our solution. 
Result so far: 1863.3
If we take 249 away from 310, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 8:
If we divide 610 by 83, we get 7 and a remainder of 29.
The next digit of our result is 7. 
Result so far: 1863.37
Subtracting 581 from 610 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 9:
If we divide 290 by 83, we get 3 and a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 1863.373
Subtract 249 from 290 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 10:
The number 83 fits into 410 4 times, leaving a remainder of 78.
Write down 4 as next digit of the result. 
Result so far: 1863.3734
If we take 332 away from 410, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 11:
If we divide 780 by 83, we get 9 and a remainder of 33.
Write down 9 as next digit of the result. 
Result so far: 1863.37349
Subtracting 747 from 780 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 12:
83 goes into 330 3 times with a remainder of 81.
The next digit of our result is 3. 
Result so far: 1863.373493
Deduct 249 from 330 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 13:
When dividing 810 by 83, we get 9 with a remainder of 63.
The next digit of our result is 9. 
Result so far: 1863.3734939
The remainder is 63 after subtracting 747 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 14:
83 can be fit into 630 7 times, resulting in a remainder of 49.
The next digit of our result is 7. 
Result so far: 1863.37349397
If we subtract 581 from 630, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

After the division, we end up with 1863.37349397 and a remainder of 4.9e-08.
