487959 ÷ 83 
The aim is to understand the frequency of 83 in 487959.

Step 1:
If we divide 4 by 83, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 83

Advancing to step 2:
48 divided by 83 is 0 with a remainder of 48.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 48, we end up with 48.
Take the next digit (7) from the dividend and append it to 48, then repeat: 487 / 83

Step 3:
83 goes into 487 5 times with a remainder of 72.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 72 after subtracting 415 from 487.
Fetch the next digit (9) from the dividend, attach it to 72 and continue: 729 / 83

Going ahead to step 4:
If we divide 729 by 83, we get 8 and a remainder of 65.
The next digit of our result is 8. 
Result so far: 58.0
Deduct 664 from 729 and we're left with 65.
Grab the next digit (5) from the dividend, add it to 65, then carry on: 655 / 83

On to step 5:
When dividing 655 by 83, we get 7 with a remainder of 74.
Write down 7 as next digit of the result. 
Result so far: 587.0
Subtract 581 from 655 to get 74.
Grab the next digit (9) from the dividend, add it to 74, then carry on: 749 / 83

Advancing to step 6:
When dividing 749 by 83, we get 9 with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 5879.0
If we take 747 away from 749, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
83 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 5879.0
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
200 divided by 83 is 2 with a remainder of 34.
Write down 2 as next digit of the result. 
Result so far: 5879.02
Subtract 166 from 200 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 9:
83 goes into 340 4 times with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 5879.024
The remainder is 8 after subtracting 332 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
83 can be fit into 80 0 times, resulting in a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 5879.024
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 11:
When dividing 800 by 83, we get 9 with a remainder of 53.
Use 9 as the next digit of our solution. 
Result so far: 5879.02409
If we subtract 747 from 800, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 12:
83 can be fit into 530 6 times, resulting in a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 5879.024096
Subtracting 498 from 530 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 13:
83 goes into 320 3 times with a remainder of 71.
The number 3 becomes the next digit in our result. 
Result so far: 5879.0240963
If we subtract 249 from 320, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 14:
83 goes into 710 8 times with a remainder of 46.
Put 8 as the next digit of the answer. 
Result so far: 5879.02409638
If we subtract 664 from 710, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The quotient of the division is 5879.02409638, and the remainder is 4.6e-08.
