We're dividing 343029 by 51 
The aim is to understand the frequency of 51 in 343029.

Going ahead to step 1:
51 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 51

On to step 2:
51 goes into 34 0 times with a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 34 and we're left with 34.
Include the next digit (3) from the dividend after 34, then repeat: 343 / 51

Moving on to step 3:
If we divide 343 by 51, we get 6 and a remainder of 37.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 37 after subtracting 306 from 343.
Take the next digit (0) from the dividend and append it to 37, then repeat: 370 / 51

Let's proceed to step 4:
51 can be fit into 370 7 times, resulting in a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 67.0
Subtracting 357 from 370 leaves us with 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 51

Let's proceed to step 5:
The number 51 fits into 132 2 times, leaving a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 672.0
Subtract 102 from 132 to get 30.
Include the next digit (9) from the dividend after 30, then repeat: 309 / 51

Moving on to step 6:
309 divided by 51 is 6 with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 6726.0
Subtracting 306 from 309 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
When dividing 30 by 51, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 6726.0
Subtracting 0 from 30 leaves us 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.

Let's proceed to step 8:
51 can be fit into 300 5 times, resulting in a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 6726.05
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.

On to step 9:
When dividing 450 by 51, we get 8 with a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 6726.058
If we take 408 away from 450, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 10:
If we divide 420 by 51, we get 8 and a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 6726.0588
The remainder is 12 after subtracting 408 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 6726.0588, and the remainder is 0.00012.
