We divide 436904 by 51
The aim is to understand the frequency of 51 in 436904.

Advancing to step 1:
The number 51 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 51

Step 2:
51 can be fit into 43 0 times, resulting in a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Fetch the next digit (6) from the dividend, attach it to 43 and continue: 436 / 51

On to step 3:
51 can be fit into 436 8 times, resulting in a remainder of 28.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 408 from 436 leaves us with 28.
Include the next digit (9) from the dividend after 28, then repeat: 289 / 51

Step 4:
51 can be fit into 289 5 times, resulting in a remainder of 34.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
Deduct 255 from 289 and we're left with 34.
Include the next digit (0) from the dividend after 34, then repeat: 340 / 51

On to step 5:
When dividing 340 by 51, we get 6 with a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 856.0
Deduct 306 from 340 and we're left with 34.
Grab the next digit (4) from the dividend, add it to 34, then carry on: 344 / 51

Let's proceed to step 6:
The number 51 fits into 344 6 times, leaving a remainder of 38.
Use 6 as the next digit of our solution. 
Result so far: 8566.0
The remainder is 38 after subtracting 306 from 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 7:
380 divided by 51 is 7 with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 8566.7
If we take 357 away from 380, we end up 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.

Let's proceed to step 8:
51 goes into 230 4 times with a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 8566.74
The remainder is 26 after subtracting 204 from 230.
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 9:
260 divided by 51 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 8566.745
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.

Going ahead to step 10:
The number 51 fits into 50 0 times, leaving a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 8566.745
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 11:
51 goes into 500 9 times with a remainder of 41.
The next digit of our result is 9. 
Result so far: 8566.74509
Subtract 459 from 500 to 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.

Advancing to step 12:
When dividing 410 by 51, we get 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 8566.745098
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 13:
51 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 8566.745098
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
If we divide 200 by 51, we get 3 and a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 8566.74509803
Subtract 153 from 200 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The final result is 8566.74509803 with a remainder of 4.7e-08.
