Let's divide 685578 by 51
The aim is to understand the frequency of 51 in 685578.

Let's proceed to step 1:
51 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 51

Moving on to step 2:
The number 51 fits into 68 1 times, leaving a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 51 from 68 and we're left with 17.
Bring next digit (5) of the dividend behind the 17 and repeat the process: 175 / 51

On to step 3:
51 can be fit into 175 3 times, resulting in a remainder of 22.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 153 from 175 to get 22.
Append the next digit (5) from the dividend to 22 and continue with: 225 / 51

Advancing to step 4:
When dividing 225 by 51, we get 4 with a remainder of 21.
The next digit of our result is 4. 
Result so far: 134.0
Subtract 204 from 225 to get 21.
Bring next digit (7) of the dividend behind the 21 and repeat the process: 217 / 51

Advancing to step 5:
217 divided by 51 is 4 with a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 1344.0
If we subtract 204 from 217, we get 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 51

Let's proceed to step 6:
51 can be fit into 138 2 times, resulting in a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 13442.0
The remainder is 36 after subtracting 102 from 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 7:
51 goes into 360 7 times with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 13442.7
If we subtract 357 from 360, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 8:
51 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 13442.7
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 9:
If we divide 300 by 51, we get 5 and a remainder of 45.
The next digit of our result is 5. 
Result so far: 13442.705
If we subtract 255 from 300, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 10:
51 can be fit into 450 8 times, resulting in a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 13442.7058
If we subtract 408 from 450, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 11:
51 can be fit into 420 8 times, resulting in a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 13442.70588
If we subtract 408 from 420, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 13442.70588 with a balance of 1.2e-05.
