We divide 321928 by 51
The aim is to understand the frequency of 51 in 321928.

Advancing to step 1:
If we divide 3 by 51, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 51

Advancing to step 2:
51 can be fit into 32 0 times, resulting in a remainder of 32.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 32, we get 32.
Grab the next digit (1) from the dividend, add it to 32, then carry on: 321 / 51

Step 3:
321 divided by 51 is 6 with a remainder of 15.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 306 away from 321, we end up with 15.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 51

Step 4:
51 can be fit into 159 3 times, resulting in a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 63.0
The remainder is 6 after subtracting 153 from 159.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 51

Step 5:
51 can be fit into 62 1 times, resulting in a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 631.0
If we subtract 51 from 62, we get 11.
Fetch the next digit (8) from the dividend, attach it to 11 and continue: 118 / 51

Let's proceed to step 6:
When dividing 118 by 51, we get 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 6312.0
Deduct 102 from 118 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 7:
The number 51 fits into 160 3 times, leaving a remainder of 7.
The next digit of our result is 3. 
Result so far: 6312.3
If we subtract 153 from 160, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 8:
51 can be fit into 70 1 times, resulting in a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 6312.31
Subtracting 51 from 70 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 9:
When dividing 190 by 51, we get 3 with a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 6312.313
Deduct 153 from 190 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 10:
If we divide 370 by 51, we get 7 and a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 6312.3137
If we subtract 357 from 370, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 11:
51 can be fit into 130 2 times, resulting in a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 6312.31372
If we subtract 102 from 130, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 12:
51 goes into 280 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 6312.313725
If we take 255 away from 280, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 13:
51 goes into 250 4 times with a remainder of 46.
The next digit of our result is 4. 
Result so far: 6312.3137254
Deduct 204 from 250 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 14:
51 goes into 460 9 times with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 6312.31372549
Subtract 459 from 460 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Our division results in 6312.31372549 with a remaining 1e-09.
