We divide 378515 by 83
The aim is to understand the frequency of 83 in 378515.

On to step 1:
83 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 83

Advancing to step 2:
When dividing 37 by 83, we get 0 with a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Include the next digit (8) from the dividend after 37, then repeat: 378 / 83

Moving on to step 3:
When dividing 378 by 83, we get 4 with a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 46 after subtracting 332 from 378.
Bring next digit (5) of the dividend behind the 46 and repeat the process: 465 / 83

On to step 4:
83 can be fit into 465 5 times, resulting in a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 45.0
If we take 415 away from 465, we end up with 50.
Bring next digit (1) of the dividend behind the 50 and repeat the process: 501 / 83

Going ahead to step 5:
83 goes into 501 6 times with a remainder of 3.
The next digit of our result is 6. 
Result so far: 456.0
The remainder is 3 after subtracting 498 from 501.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 83

Step 6:
35 divided by 83 is 0 with a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 4560.0
If we subtract 0 from 35, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 7:
The number 83 fits into 350 4 times, leaving a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 4560.4
Deduct 332 from 350 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 8:
When dividing 180 by 83, we get 2 with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 4560.42
Subtract 166 from 180 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
The number 83 fits into 140 1 times, leaving a remainder of 57.
Write down 1 as next digit of the result. 
Result so far: 4560.421
If we subtract 83 from 140, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 10:
If we divide 570 by 83, we get 6 and a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 4560.4216
Deduct 498 from 570 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 11:
The number 83 fits into 720 8 times, leaving a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 4560.42168
Subtracting 664 from 720 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 12:
If we divide 560 by 83, we get 6 and a remainder of 62.
The number 6 becomes the next digit in our result. 
Result so far: 4560.421686
Deduct 498 from 560 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 13:
If we divide 620 by 83, we get 7 and a remainder of 39.
The next digit of our result is 7. 
Result so far: 4560.4216867
Deduct 581 from 620 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 14:
The number 83 fits into 390 4 times, leaving a remainder of 58.
The next digit of our result is 4. 
Result so far: 4560.42168674
Subtract 332 from 390 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The quotient of the division is 4560.42168674, and the remainder is 5.8e-08.
