604140 ÷ 83 
The aim is to understand the frequency of 83 in 604140.

Step 1:
83 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 83

On to step 2:
60 divided by 83 is 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 60 after subtracting 0 from 60.
Append the next digit (4) from the dividend to 60 and continue with: 604 / 83

On to step 3:
If we divide 604 by 83, we get 7 and a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 23 after subtracting 581 from 604.
Bring next digit (1) of the dividend behind the 23 and repeat the process: 231 / 83

Let's proceed to step 4:
231 divided by 83 is 2 with a remainder of 65.
Put 2 as the next digit of the answer. 
Result so far: 72.0
If we subtract 166 from 231, we get 65.
Fetch the next digit (4) from the dividend, attach it to 65 and continue: 654 / 83

On to step 5:
The number 83 fits into 654 7 times, leaving a remainder of 73.
Put 7 as the next digit of the answer. 
Result so far: 727.0
If we take 581 away from 654, we end up with 73.
Include the next digit (0) from the dividend after 73, then repeat: 730 / 83

Going ahead to step 6:
The number 83 fits into 730 8 times, leaving a remainder of 66.
Record the quotient 8 as the next digit in the result. 
Result so far: 7278.0
Deduct 664 from 730 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 7:
83 can be fit into 660 7 times, resulting in a remainder of 79.
Put 7 as the next digit of the answer. 
Result so far: 7278.7
Deduct 581 from 660 and we're left 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.

Advancing to step 8:
If we divide 790 by 83, we get 9 and a remainder of 43.
The number 9 becomes the next digit in our result. 
Result so far: 7278.79
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.

Going ahead to step 9:
430 divided by 83 is 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 7278.795
Subtracting 415 from 430 leaves us 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 10:
The number 83 fits into 150 1 times, leaving a remainder of 67.
The next digit of our result is 1. 
Result so far: 7278.7951
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.

Step 11:
If we divide 670 by 83, we get 8 and a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 7278.79518
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.

Advancing to step 12:
When dividing 60 by 83, we get 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 7278.79518
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 13:
600 divided by 83 is 7 with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 7278.7951807
Deduct 581 from 600 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 14:
If we divide 190 by 83, we get 2 and a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 7278.79518072
Subtracting 166 from 190 leaves us 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.

The quotient of the division is 7278.79518072, and the remainder is 2.4e-08.
