378249 divided by 83 
The aim is to understand the frequency of 83 in 378249.

On to step 1:
If we divide 3 by 83, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 83

Moving on to step 2:
If we divide 37 by 83, we get 0 and a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 37 to get 37.
Append the next digit (8) from the dividend to 37 and continue with: 378 / 83

Moving on to step 3:
If we divide 378 by 83, we get 4 and a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 332 from 378 leaves us with 46.
Grab the next digit (2) from the dividend, add it to 46, then carry on: 462 / 83

On to step 4:
83 can be fit into 462 5 times, resulting in a remainder of 47.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
If we subtract 415 from 462, we get 47.
Grab the next digit (4) from the dividend, add it to 47, then carry on: 474 / 83

On to step 5:
If we divide 474 by 83, we get 5 and a remainder of 59.
Put 5 as the next digit of the answer. 
Result so far: 455.0
If we take 415 away from 474, we end up with 59.
Fetch the next digit (9) from the dividend, attach it to 59 and continue: 599 / 83

Step 6:
83 can be fit into 599 7 times, resulting in a remainder of 18.
The next digit of our result is 7. 
Result so far: 4557.0
Deduct 581 from 599 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 7:
When dividing 180 by 83, we get 2 with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 4557.2
If we take 166 away from 180, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
When dividing 140 by 83, we get 1 with a remainder of 57.
The number 1 becomes the next digit in our result. 
Result so far: 4557.21
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.

Let's proceed to step 9:
When dividing 570 by 83, we get 6 with a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 4557.216
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.

Going ahead to step 10:
720 divided by 83 is 8 with a remainder of 56.
The next digit of our result is 8. 
Result so far: 4557.2168
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.

Step 11:
The number 83 fits into 560 6 times, leaving a remainder of 62.
Record the quotient 6 as the next digit in the result. 
Result so far: 4557.21686
If we subtract 498 from 560, we get 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 12:
83 goes into 620 7 times with a remainder of 39.
Use 7 as the next digit of our solution. 
Result so far: 4557.216867
If we take 581 away from 620, we end up 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 13:
83 can be fit into 390 4 times, resulting in a remainder of 58.
The next digit of our result is 4. 
Result so far: 4557.2168674
If we subtract 332 from 390, we 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.

On to step 14:
When dividing 580 by 83, we get 6 with a remainder of 82.
Use 6 as the next digit of our solution. 
Result so far: 4557.21686746
The remainder is 82 after subtracting 498 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Our division results in 4557.21686746 with a remaining 8.2e-08.
