We're dividing 378776 by 83 
The aim is to understand the frequency of 83 in 378776.

Advancing to step 1:
83 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 83

Let's proceed to step 2:
83 goes into 37 0 times with a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Append the next digit (8) from the dividend to 37 and continue with: 378 / 83

Going ahead to step 3:
83 can be fit into 378 4 times, resulting in a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 332 from 378 leaves us with 46.
Bring next digit (7) of the dividend behind the 46 and repeat the process: 467 / 83

On to step 4:
When dividing 467 by 83, we get 5 with a remainder of 52.
Use 5 as the next digit of our solution. 
Result so far: 45.0
Subtract 415 from 467 to get 52.
Bring next digit (7) of the dividend behind the 52 and repeat the process: 527 / 83

Step 5:
527 divided by 83 is 6 with a remainder of 29.
The number 6 becomes the next digit in our result. 
Result so far: 456.0
Subtracting 498 from 527 leaves us with 29.
Fetch the next digit (6) from the dividend, attach it to 29 and continue: 296 / 83

Moving on to step 6:
When dividing 296 by 83, we get 3 with a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 4563.0
Subtract 249 from 296 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 7:
The number 83 fits into 470 5 times, leaving a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 4563.5
Deduct 415 from 470 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 8:
If we divide 550 by 83, we get 6 and a remainder of 52.
The next digit of our result is 6. 
Result so far: 4563.56
Subtracting 498 from 550 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 9:
The number 83 fits into 520 6 times, leaving a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 4563.566
Subtracting 498 from 520 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 4563.566 with a remainder of 0.0022.
