Let's divide 777866 by 83
The aim is to understand the frequency of 83 in 777866.

On to step 1:
The number 83 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 83

Let's proceed to step 2:
77 divided by 83 is 0 with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Append the next digit (7) from the dividend to 77 and continue with: 777 / 83

On to step 3:
83 can be fit into 777 9 times, resulting in a remainder of 30.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 747 from 777 and we're left with 30.
Bring next digit (8) of the dividend behind the 30 and repeat the process: 308 / 83

Going ahead to step 4:
When dividing 308 by 83, we get 3 with a remainder of 59.
Write down 3 as next digit of the result. 
Result so far: 93.0
If we take 249 away from 308, we end up with 59.
Bring next digit (6) of the dividend behind the 59 and repeat the process: 596 / 83

Advancing to step 5:
The number 83 fits into 596 7 times, leaving a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 937.0
The remainder is 15 after subtracting 581 from 596.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 83

Going ahead to step 6:
If we divide 156 by 83, we get 1 and a remainder of 73.
Put 1 as the next digit of the answer. 
Result so far: 9371.0
Subtract 83 from 156 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 7:
730 divided by 83 is 8 with a remainder of 66.
The next digit of our result is 8. 
Result so far: 9371.8
The remainder is 66 after subtracting 664 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 8:
The number 83 fits into 660 7 times, leaving a remainder of 79.
The number 7 becomes the next digit in our result. 
Result so far: 9371.87
If we subtract 581 from 660, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 9:
If we divide 790 by 83, we get 9 and a remainder of 43.
Put 9 as the next digit of the answer. 
Result so far: 9371.879
If we subtract 747 from 790, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 10:
The number 83 fits into 430 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 9371.8795
Subtracting 415 from 430 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 11:
83 can be fit into 150 1 times, resulting in a remainder of 67.
Record the quotient 1 as the next digit in the result. 
Result so far: 9371.87951
The remainder is 67 after subtracting 83 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 12:
83 goes into 670 8 times with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 9371.879518
Deduct 664 from 670 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 13:
The number 83 fits into 60 0 times, leaving a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 9371.879518
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 14:
600 divided by 83 is 7 with a remainder of 19.
The next digit of our result is 7. 
Result so far: 9371.87951807
Subtracting 581 from 600 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final outcome is 9371.87951807, with a leftover of 1.9e-08.
