15494664 divided by 51 
The aim is to understand the frequency of 51 in 15494664.

On to step 1:
51 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 51

Let's proceed to step 2:
51 can be fit into 15 0 times, resulting in a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Fetch the next digit (4) from the dividend, attach it to 15 and continue: 154 / 51

Step 3:
154 divided by 51 is 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 153 from 154 to get 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 51

Advancing to step 4:
19 divided by 51 is 0 with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 30.0
If we take 0 away from 19, we end up with 19.
Bring next digit (4) of the dividend behind the 19 and repeat the process: 194 / 51

On to step 5:
194 divided by 51 is 3 with a remainder of 41.
The next digit of our result is 3. 
Result so far: 303.0
If we subtract 153 from 194, we get 41.
Take the next digit (6) from the dividend and append it to 41, then repeat: 416 / 51

On to step 6:
When dividing 416 by 51, we get 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 3038.0
The remainder is 8 after subtracting 408 from 416.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 51

Step 7:
51 can be fit into 86 1 times, resulting in a remainder of 35.
Put 1 as the next digit of the answer. 
Result so far: 30381.0
If we subtract 51 from 86, we get 35.
Grab the next digit (4) from the dividend, add it to 35, then carry on: 354 / 51

Going ahead to step 8:
51 goes into 354 6 times with a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 303816.0
If we subtract 306 from 354, we 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 9:
The number 51 fits into 480 9 times, leaving a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 303816.9
The remainder is 21 after subtracting 459 from 480.
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 10:
When dividing 210 by 51, we get 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 303816.94
Subtract 204 from 210 to get 6.
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 11:
51 goes into 60 1 times with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 303816.941
Subtract 51 from 60 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 12:
When dividing 90 by 51, we get 1 with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 303816.9411
The remainder is 39 after subtracting 51 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

In conclusion, the division gives 303816.9411 with a balance of 0.00039.
