783864 divided by 83 
The aim is to understand the frequency of 83 in 783864.

Let's proceed to step 1:
If we divide 7 by 83, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 83

On to step 2:
When dividing 78 by 83, we get 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Bring next digit (3) of the dividend behind the 78 and repeat the process: 783 / 83

Let's proceed to step 3:
83 goes into 783 9 times with a remainder of 36.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 747 from 783 leaves us with 36.
Grab the next digit (8) from the dividend, add it to 36, then carry on: 368 / 83

Let's proceed to step 4:
83 goes into 368 4 times with a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 94.0
The remainder is 36 after subtracting 332 from 368.
Grab the next digit (6) from the dividend, add it to 36, then carry on: 366 / 83

Step 5:
When dividing 366 by 83, we get 4 with a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 944.0
If we subtract 332 from 366, we get 34.
Grab the next digit (4) from the dividend, add it to 34, then carry on: 344 / 83

Going ahead to step 6:
If we divide 344 by 83, we get 4 and a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 9444.0
Subtract 332 from 344 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
When dividing 120 by 83, we get 1 with a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 9444.1
Subtract 83 from 120 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 8:
The number 83 fits into 370 4 times, leaving a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 9444.14
If we take 332 away from 370, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 9:
83 goes into 380 4 times with a remainder of 48.
The next digit of our result is 4. 
Result so far: 9444.144
Subtract 332 from 380 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 9444.144, with a leftover of 0.0048.
