12773521 ÷ 790 
The aim is to understand the frequency of 790 in 12773521.

Step 1:
When dividing 1 by 790, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 790

Going ahead to step 2:
790 can be fit into 12 0 times, resulting in a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Bring next digit (7) of the dividend behind the 12 and repeat the process: 127 / 790

Step 3:
When dividing 127 by 790, we get 0 with a remainder of 127.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 127 to get 127.
Take the next digit (7) from the dividend and append it to 127, then repeat: 1277 / 790

Advancing to step 4:
790 goes into 1277 1 times with a remainder of 487.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 790 from 1277 to get 487.
Bring next digit (3) of the dividend behind the 487 and repeat the process: 4873 / 790

Let's proceed to step 5:
When dividing 4873 by 790, we get 6 with a remainder of 133.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtracting 4740 from 4873 leaves us with 133.
Bring next digit (5) of the dividend behind the 133 and repeat the process: 1335 / 790

Going ahead to step 6:
If we divide 1335 by 790, we get 1 and a remainder of 545.
The number 1 becomes the next digit in our result. 
Result so far: 161.0
Subtracting 790 from 1335 leaves us with 545.
Fetch the next digit (2) from the dividend, attach it to 545 and continue: 5452 / 790

Advancing to step 7:
If we divide 5452 by 790, we get 6 and a remainder of 712.
Record the quotient 6 as the next digit in the result. 
Result so far: 1616.0
Deduct 4740 from 5452 and we're left with 712.
Append the next digit (1) from the dividend to 712 and continue with: 7121 / 790

Let's proceed to step 8:
7121 divided by 790 is 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 16169.0
If we subtract 7110 from 7121, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 9:
110 divided by 790 is 0 with a remainder of 110.
The number 0 becomes the next digit in our result. 
Result so far: 16169.0
If we subtract 0 from 110, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 10:
The number 790 fits into 1100 1 times, leaving a remainder of 310.
The number 1 becomes the next digit in our result. 
Result so far: 16169.01
Subtract 790 from 1100 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Advancing to step 11:
790 can be fit into 3100 3 times, resulting in a remainder of 730.
The next digit of our result is 3. 
Result so far: 16169.013
Subtracting 2370 from 3100 leaves us with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

On to step 12:
7300 divided by 790 is 9 with a remainder of 190.
The next digit of our result is 9. 
Result so far: 16169.0139
The remainder is 190 after subtracting 7110 from 7300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 13:
If we divide 1900 by 790, we get 2 and a remainder of 320.
Put 2 as the next digit of the answer. 
Result so far: 16169.01392
The remainder is 320 after subtracting 1580 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 14:
3200 divided by 790 is 4 with a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 16169.013924
Subtract 3160 from 3200 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 15:
790 can be fit into 400 0 times, resulting in a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 16169.013924
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 16:
790 can be fit into 4000 5 times, resulting in a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 16169.01392405
Subtract 3950 from 4000 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 16169.01392405 and a remainder of 5e-08.
