Let's divide 681653 by 51
The aim is to understand the frequency of 51 in 681653.

Moving on to step 1:
6 divided by 51 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 51

Going ahead to step 2:
68 divided by 51 is 1 with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 51 from 68 to get 17.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 51

Step 3:
If we divide 171 by 51, we get 3 and a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 18 after subtracting 153 from 171.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 51

Let's proceed to step 4:
When dividing 186 by 51, we get 3 with a remainder of 33.
The next digit of our result is 3. 
Result so far: 133.0
Subtract 153 from 186 to get 33.
Fetch the next digit (5) from the dividend, attach it to 33 and continue: 335 / 51

Let's proceed to step 5:
335 divided by 51 is 6 with a remainder of 29.
The next digit of our result is 6. 
Result so far: 1336.0
If we take 306 away from 335, we end up with 29.
Take the next digit (3) from the dividend and append it to 29, then repeat: 293 / 51

On to step 6:
When dividing 293 by 51, we get 5 with a remainder of 38.
Use 5 as the next digit of our solution. 
Result so far: 13365.0
If we subtract 255 from 293, 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.

Going ahead to 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: 13365.7
Subtracting 357 from 380 leaves us 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.

Moving on to step 8:
51 goes into 230 4 times with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 13365.74
Deduct 204 from 230 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 9:
51 can be fit into 260 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 13365.745
Deduct 255 from 260 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 10:
The number 51 fits into 50 0 times, leaving a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 13365.745
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
51 can be fit into 500 9 times, resulting in a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 13365.74509
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.

Moving on to step 12:
When dividing 410 by 51, we get 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 13365.745098
Deduct 408 from 410 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 13:
When dividing 20 by 51, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 13365.745098
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 14:
The number 51 fits into 200 3 times, leaving a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 13365.74509803
If we take 153 away from 200, we end up 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.

The final outcome is 13365.74509803, with a leftover of 4.7e-08.
