We're dividing 51121909 by 792 
The aim is to understand the frequency of 792 in 51121909.

Advancing to step 1:
792 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 792

Going ahead to step 2:
51 divided by 792 is 0 with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Grab the next digit (1) from the dividend, add it to 51, then carry on: 511 / 792

Let's proceed to step 3:
511 divided by 792 is 0 with a remainder of 511.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 511, we end up with 511.
Bring next digit (2) of the dividend behind the 511 and repeat the process: 5112 / 792

Moving on to step 4:
5112 divided by 792 is 6 with a remainder of 360.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 4752 from 5112 to get 360.
Append the next digit (1) from the dividend to 360 and continue with: 3601 / 792

Going ahead to step 5:
If we divide 3601 by 792, we get 4 and a remainder of 433.
The next digit of our result is 4. 
Result so far: 64.0
Subtract 3168 from 3601 to get 433.
Grab the next digit (9) from the dividend, add it to 433, then carry on: 4339 / 792

Let's proceed to step 6:
The number 792 fits into 4339 5 times, leaving a remainder of 379.
Record the quotient 5 as the next digit in the result. 
Result so far: 645.0
If we subtract 3960 from 4339, we get 379.
Grab the next digit (0) from the dividend, add it to 379, then carry on: 3790 / 792

Step 7:
The number 792 fits into 3790 4 times, leaving a remainder of 622.
Record the quotient 4 as the next digit in the result. 
Result so far: 6454.0
Subtracting 3168 from 3790 leaves us with 622.
Fetch the next digit (9) from the dividend, attach it to 622 and continue: 6229 / 792

Let's proceed to step 8:
If we divide 6229 by 792, we get 7 and a remainder of 685.
Write down 7 as next digit of the result. 
Result so far: 64547.0
Deduct 5544 from 6229 and we're left with 685.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

Advancing to step 9:
792 goes into 6850 8 times with a remainder of 514.
The next digit of our result is 8. 
Result so far: 64547.8
If we subtract 6336 from 6850, we get 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Moving on to step 10:
5140 divided by 792 is 6 with a remainder of 388.
The number 6 becomes the next digit in our result. 
Result so far: 64547.86
If we take 4752 away from 5140, we end up with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Step 11:
792 can be fit into 3880 4 times, resulting in a remainder of 712.
Record the quotient 4 as the next digit in the result. 
Result so far: 64547.864
Subtracting 3168 from 3880 leaves us with 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

Step 12:
When dividing 7120 by 792, we get 8 with a remainder of 784.
Record the quotient 8 as the next digit in the result. 
Result so far: 64547.8648
Deduct 6336 from 7120 and we're left with 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

Let's proceed to step 13:
If we divide 7840 by 792, we get 9 and a remainder of 712.
Write down 9 as next digit of the result. 
Result so far: 64547.86489
Deduct 7128 from 7840 and we're left with 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

On to step 14:
The number 792 fits into 7120 8 times, leaving a remainder of 784.
Write down 8 as next digit of the result. 
Result so far: 64547.864898
If we subtract 6336 from 7120, we get 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

Going ahead to step 15:
When dividing 7840 by 792, we get 9 with a remainder of 712.
The number 9 becomes the next digit in our result. 
Result so far: 64547.8648989
If we subtract 7128 from 7840, we get 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

On to step 16:
The number 792 fits into 7120 8 times, leaving a remainder of 784.
Write down 8 as next digit of the result. 
Result so far: 64547.86489898
If we take 6336 away from 7120, we end up with 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

The final outcome is 64547.86489898, with a leftover of 7.84e-07.
