We're dividing 339749 by 51 
The aim is to understand the frequency of 51 in 339749.

Let's proceed to step 1:
If we divide 3 by 51, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 51

Let's proceed to step 2:
51 can be fit into 33 0 times, resulting in a remainder of 33.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 33 to get 33.
Grab the next digit (9) from the dividend, add it to 33, then carry on: 339 / 51

On to step 3:
When dividing 339 by 51, we get 6 with a remainder of 33.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 306 from 339, we get 33.
Fetch the next digit (7) from the dividend, attach it to 33 and continue: 337 / 51

Advancing to step 4:
337 divided by 51 is 6 with a remainder of 31.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
If we take 306 away from 337, we end up with 31.
Bring next digit (4) of the dividend behind the 31 and repeat the process: 314 / 51

Step 5:
The number 51 fits into 314 6 times, leaving a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 666.0
If we take 306 away from 314, we end up with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 51

Advancing to step 6:
If we divide 89 by 51, we get 1 and a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 6661.0
If we subtract 51 from 89, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 7:
51 can be fit into 380 7 times, resulting in a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 6661.7
If we take 357 away from 380, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 8:
If we divide 230 by 51, we get 4 and a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 6661.74
The remainder is 26 after subtracting 204 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 9:
260 divided by 51 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 6661.745
If we subtract 255 from 260, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 10:
If we divide 50 by 51, we get 0 and a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 6661.745
If we subtract 0 from 50, we 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.

Step 11:
If we divide 500 by 51, we get 9 and a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 6661.74509
Subtracting 459 from 500 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 12:
The number 51 fits into 410 8 times, leaving a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 6661.745098
The remainder is 2 after subtracting 408 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 13:
If we divide 20 by 51, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 6661.745098
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 14:
If we divide 200 by 51, we get 3 and a remainder of 47.
The next digit of our result is 3. 
Result so far: 6661.74509803
Subtract 153 from 200 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The quotient of the division is 6661.74509803, and the remainder is 4.7e-08.
