We look at the division of 348353 by 51 
The aim is to understand the frequency of 51 in 348353.

Advancing to step 1:
51 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 51

Let's proceed to step 2:
The number 51 fits into 34 0 times, leaving a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Grab the next digit (8) from the dividend, add it to 34, then carry on: 348 / 51

Let's proceed to step 3:
51 can be fit into 348 6 times, resulting in a remainder of 42.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 42 after subtracting 306 from 348.
Include the next digit (3) from the dividend after 42, then repeat: 423 / 51

On to step 4:
When dividing 423 by 51, we get 8 with a remainder of 15.
The next digit of our result is 8. 
Result so far: 68.0
If we take 408 away from 423, we end up with 15.
Append the next digit (5) from the dividend to 15 and continue with: 155 / 51

Going ahead to step 5:
When dividing 155 by 51, we get 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 683.0
Subtracting 153 from 155 leaves us with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 51

Step 6:
The number 51 fits into 23 0 times, leaving a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 6830.0
Deduct 0 from 23 and we're left 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.

On to step 7:
51 can be fit into 230 4 times, resulting in a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 6830.4
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.

On to step 8:
260 divided by 51 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 6830.45
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.

Moving on to step 9:
51 goes into 50 0 times with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 6830.45
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
When dividing 500 by 51, we get 9 with a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 6830.4509
If we subtract 459 from 500, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 11:
If we divide 410 by 51, we get 8 and a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 6830.45098
If we take 408 away from 410, we end up 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.

On to step 12:
51 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 6830.45098
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.

Moving on to step 13:
200 divided by 51 is 3 with a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 6830.4509803
Deduct 153 from 200 and we're left 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.

On to step 14:
51 goes into 470 9 times with a remainder of 11.
The next digit of our result is 9. 
Result so far: 6830.45098039
If we take 459 away from 470, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The quotient of the division is 6830.45098039, and the remainder is 1.1e-08.
