Let's divide 380407 by 83
The aim is to understand the frequency of 83 in 380407.

Advancing to step 1:
83 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 83

On to step 2:
83 can be fit into 38 0 times, resulting in a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Bring next digit (0) of the dividend behind the 38 and repeat the process: 380 / 83

Advancing to step 3:
If we divide 380 by 83, we get 4 and a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 332 from 380, we get 48.
Append the next digit (4) from the dividend to 48 and continue with: 484 / 83

Step 4:
The number 83 fits into 484 5 times, leaving a remainder of 69.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
If we take 415 away from 484, we end up with 69.
Grab the next digit (0) from the dividend, add it to 69, then carry on: 690 / 83

Going ahead to step 5:
When dividing 690 by 83, we get 8 with a remainder of 26.
Use 8 as the next digit of our solution. 
Result so far: 458.0
If we subtract 664 from 690, we get 26.
Append the next digit (7) from the dividend to 26 and continue with: 267 / 83

Advancing to step 6:
83 goes into 267 3 times with a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 4583.0
If we take 249 away from 267, we end up 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.

Going ahead to step 7:
83 goes into 180 2 times with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 4583.2
Subtracting 166 from 180 leaves us 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:
83 can be fit into 140 1 times, resulting in a remainder of 57.
The number 1 becomes the next digit in our result. 
Result so far: 4583.21
If we take 83 away from 140, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 9:
83 can be fit into 570 6 times, resulting in a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 4583.216
Subtracting 498 from 570 leaves us 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.

Step 10:
The number 83 fits into 720 8 times, leaving a remainder of 56.
The next digit of our result is 8. 
Result so far: 4583.2168
Subtract 664 from 720 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 11:
83 goes into 560 6 times with a remainder of 62.
Record the quotient 6 as the next digit in the result. 
Result so far: 4583.21686
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.

Moving on to step 12:
83 can be fit into 620 7 times, resulting in a remainder of 39.
Use 7 as the next digit of our solution. 
Result so far: 4583.216867
Subtract 581 from 620 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 13:
If we divide 390 by 83, we get 4 and a remainder of 58.
The number 4 becomes the next digit in our result. 
Result so far: 4583.2168674
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.

Step 14:
580 divided by 83 is 6 with a remainder of 82.
Write down 6 as next digit of the result. 
Result so far: 4583.21686746
If we subtract 498 from 580, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

The final outcome is 4583.21686746, with a leftover of 8.2e-08.
