Let's divide 11521157 by 51
The aim is to understand the frequency of 51 in 11521157.

Step 1:
1 divided by 51 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 51

Advancing to step 2:
51 can be fit into 11 0 times, resulting in a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 11 and we're left with 11.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 51

Advancing to step 3:
If we divide 115 by 51, we get 2 and a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 102 from 115, we get 13.
Append the next digit (2) from the dividend to 13 and continue with: 132 / 51

Going ahead to step 4:
132 divided by 51 is 2 with a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 22.0
If we take 102 away from 132, we end up with 30.
Fetch the next digit (1) from the dividend, attach it to 30 and continue: 301 / 51

Moving on to step 5:
51 can be fit into 301 5 times, resulting in a remainder of 46.
The next digit of our result is 5. 
Result so far: 225.0
If we take 255 away from 301, we end up with 46.
Grab the next digit (1) from the dividend, add it to 46, then carry on: 461 / 51

Going ahead to step 6:
461 divided by 51 is 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 2259.0
Subtract 459 from 461 to get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 51

Step 7:
51 can be fit into 25 0 times, resulting in a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 22590.0
If we take 0 away from 25, we end up with 25.
Grab the next digit (7) from the dividend, add it to 25, then carry on: 257 / 51

Let's proceed to step 8:
If we divide 257 by 51, we get 5 and a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 225905.0
Subtracting 255 from 257 leaves us 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.

Going ahead to step 9:
If we divide 20 by 51, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 225905.0
If we subtract 0 from 20, we 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 10:
When dividing 200 by 51, we get 3 with a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 225905.03
Subtracting 153 from 200 leaves us 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.

Let's proceed to step 11:
470 divided by 51 is 9 with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 225905.039
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.

On to step 12:
When dividing 110 by 51, we get 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 225905.0392
Subtract 102 from 110 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 13:
51 can be fit into 80 1 times, resulting in a remainder of 29.
The next digit of our result is 1. 
Result so far: 225905.03921
Subtract 51 from 80 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 14:
51 can be fit into 290 5 times, resulting in a remainder of 35.
The next digit of our result is 5. 
Result so far: 225905.039215
The remainder is 35 after subtracting 255 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 15:
51 goes into 350 6 times with a remainder of 44.
The next digit of our result is 6. 
Result so far: 225905.0392156
The remainder is 44 after subtracting 306 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 16:
51 goes into 440 8 times with a remainder of 32.
The next digit of our result is 8. 
Result so far: 225905.03921568
Deduct 408 from 440 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 225905.03921568 with a balance of 3.2e-08.
