We look at the division of 64837779 by 790 
The aim is to understand the frequency of 790 in 64837779.

Going ahead to step 1:
When dividing 6 by 790, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 790

Step 2:
64 divided by 790 is 0 with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Append the next digit (8) from the dividend to 64 and continue with: 648 / 790

Step 3:
When dividing 648 by 790, we get 0 with a remainder of 648.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 648 leaves us with 648.
Take the next digit (3) from the dividend and append it to 648, then repeat: 6483 / 790

Advancing to step 4:
The number 790 fits into 6483 8 times, leaving a remainder of 163.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 6320 from 6483 to get 163.
Include the next digit (7) from the dividend after 163, then repeat: 1637 / 790

Let's proceed to step 5:
790 goes into 1637 2 times with a remainder of 57.
Use 2 as the next digit of our solution. 
Result so far: 82.0
Subtracting 1580 from 1637 leaves us with 57.
Take the next digit (7) from the dividend and append it to 57, then repeat: 577 / 790

Let's proceed to step 6:
577 divided by 790 is 0 with a remainder of 577.
Write down 0 as next digit of the result. 
Result so far: 820.0
Subtract 0 from 577 to get 577.
Bring next digit (7) of the dividend behind the 577 and repeat the process: 5777 / 790

Advancing to step 7:
When dividing 5777 by 790, we get 7 with a remainder of 247.
Record the quotient 7 as the next digit in the result. 
Result so far: 8207.0
If we take 5530 away from 5777, we end up with 247.
Append the next digit (9) from the dividend to 247 and continue with: 2479 / 790

On to step 8:
790 can be fit into 2479 3 times, resulting in a remainder of 109.
Use 3 as the next digit of our solution. 
Result so far: 82073.0
Deduct 2370 from 2479 and we're left with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Advancing to step 9:
790 can be fit into 1090 1 times, resulting in a remainder of 300.
Use 1 as the next digit of our solution. 
Result so far: 82073.1
If we subtract 790 from 1090, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 10:
790 goes into 3000 3 times with a remainder of 630.
Put 3 as the next digit of the answer. 
Result so far: 82073.13
The remainder is 630 after subtracting 2370 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Going ahead to step 11:
790 can be fit into 6300 7 times, resulting in a remainder of 770.
The number 7 becomes the next digit in our result. 
Result so far: 82073.137
Deduct 5530 from 6300 and we're left with 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Step 12:
790 goes into 7700 9 times with a remainder of 590.
The next digit of our result is 9. 
Result so far: 82073.1379
Deduct 7110 from 7700 and we're left with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Let's proceed to step 13:
5900 divided by 790 is 7 with a remainder of 370.
The next digit of our result is 7. 
Result so far: 82073.13797
Subtracting 5530 from 5900 leaves us with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Let's proceed to step 14:
790 can be fit into 3700 4 times, resulting in a remainder of 540.
The next digit of our result is 4. 
Result so far: 82073.137974
The remainder is 540 after subtracting 3160 from 3700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Advancing to step 15:
When dividing 5400 by 790, we get 6 with a remainder of 660.
Put 6 as the next digit of the answer. 
Result so far: 82073.1379746
If we take 4740 away from 5400, we end up with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Let's proceed to step 16:
790 can be fit into 6600 8 times, resulting in a remainder of 280.
The next digit of our result is 8. 
Result so far: 82073.13797468
Subtracting 6320 from 6600 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

The final result is 82073.13797468 with a remainder of 2.8e-07.
