We're dividing 868838 by 51 
The aim is to understand the frequency of 51 in 868838.

Moving on to step 1:
51 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 51

Going ahead to step 2:
When dividing 86 by 51, we get 1 with a remainder of 35.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 35 after subtracting 51 from 86.
Take the next digit (8) from the dividend and append it to 35, then repeat: 358 / 51

Moving on to step 3:
The number 51 fits into 358 7 times, leaving a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
The remainder is 1 after subtracting 357 from 358.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 51

Going ahead to step 4:
The number 51 fits into 18 0 times, leaving a remainder of 18.
The next digit of our result is 0. 
Result so far: 170.0
The remainder is 18 after subtracting 0 from 18.
Fetch the next digit (3) from the dividend, attach it to 18 and continue: 183 / 51

Advancing to step 5:
The number 51 fits into 183 3 times, leaving a remainder of 30.
The next digit of our result is 3. 
Result so far: 1703.0
Subtracting 153 from 183 leaves us with 30.
Append the next digit (8) from the dividend to 30 and continue with: 308 / 51

On to step 6:
51 can be fit into 308 6 times, resulting in a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 17036.0
The remainder is 2 after subtracting 306 from 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
When dividing 20 by 51, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 17036.0
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.

Step 8:
51 can be fit into 200 3 times, resulting in a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 17036.03
Subtracting 153 from 200 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 9:
The number 51 fits into 470 9 times, leaving a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 17036.039
The remainder is 11 after subtracting 459 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 10:
The number 51 fits into 110 2 times, leaving a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 17036.0392
Subtract 102 from 110 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
The number 51 fits into 80 1 times, leaving a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 17036.03921
Subtract 51 from 80 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 12:
The number 51 fits into 290 5 times, leaving a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 17036.039215
The remainder is 35 after subtracting 255 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 13:
The number 51 fits into 350 6 times, leaving a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 17036.0392156
The remainder is 44 after subtracting 306 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 14:
If we divide 440 by 51, we get 8 and a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 17036.03921568
If we subtract 408 from 440, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 17036.03921568, and the remainder is 3.2e-08.
