Let's divide 705399 by 51
The aim is to understand the frequency of 51 in 705399.

Let's proceed to step 1:
51 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 51

Moving on to step 2:
The number 51 fits into 70 1 times, leaving a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 51 away from 70, we end up with 19.
Take the next digit (5) from the dividend and append it to 19, then repeat: 195 / 51

Step 3:
When dividing 195 by 51, we get 3 with a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 42 after subtracting 153 from 195.
Fetch the next digit (3) from the dividend, attach it to 42 and continue: 423 / 51

Step 4:
If we divide 423 by 51, we get 8 and a remainder of 15.
The next digit of our result is 8. 
Result so far: 138.0
Subtracting 408 from 423 leaves us with 15.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 51

Moving on to step 5:
51 goes into 159 3 times with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 1383.0
Subtract 153 from 159 to get 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 51

Moving on to step 6:
51 can be fit into 69 1 times, resulting in a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 13831.0
If we take 51 away from 69, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 7:
The number 51 fits into 180 3 times, leaving a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 13831.3
If we subtract 153 from 180, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 8:
When dividing 270 by 51, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 13831.35
The remainder is 15 after subtracting 255 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 9:
51 can be fit into 150 2 times, resulting in a remainder of 48.
The next digit of our result is 2. 
Result so far: 13831.352
Subtract 102 from 150 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 10:
51 can be fit into 480 9 times, resulting in a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 13831.3529
If we subtract 459 from 480, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 11:
210 divided by 51 is 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 13831.35294
The remainder is 6 after subtracting 204 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 12:
51 goes into 60 1 times with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 13831.352941
The remainder is 9 after subtracting 51 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 13:
90 divided by 51 is 1 with a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 13831.3529411
Subtract 51 from 90 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The final outcome is 13831.3529411, with a leftover of 3.9e-07.
