63159566 ÷ 51 
The aim is to understand the frequency of 51 in 63159566.

Going ahead to step 1:
51 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 51

Step 2:
51 goes into 63 1 times with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 51 from 63 leaves us with 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 51

Let's proceed to step 3:
If we divide 121 by 51, we get 2 and a remainder of 19.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 19 after subtracting 102 from 121.
Bring next digit (5) of the dividend behind the 19 and repeat the process: 195 / 51

Moving on to step 4:
51 can be fit into 195 3 times, resulting in a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 123.0
Subtract 153 from 195 to get 42.
Include the next digit (9) from the dividend after 42, then repeat: 429 / 51

On to step 5:
429 divided by 51 is 8 with a remainder of 21.
The number 8 becomes the next digit in our result. 
Result so far: 1238.0
Subtract 408 from 429 to get 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 51

Moving on to step 6:
If we divide 215 by 51, we get 4 and a remainder of 11.
The number 4 becomes the next digit in our result. 
Result so far: 12384.0
The remainder is 11 after subtracting 204 from 215.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 51

Advancing to step 7:
The number 51 fits into 116 2 times, leaving a remainder of 14.
The next digit of our result is 2. 
Result so far: 123842.0
The remainder is 14 after subtracting 102 from 116.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 51

Let's proceed to step 8:
51 goes into 146 2 times with a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 1238422.0
If we take 102 away from 146, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
51 can be fit into 440 8 times, resulting in a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 1238422.8
Subtracting 408 from 440 leaves us 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.

Going ahead to step 10:
When dividing 320 by 51, we get 6 with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 1238422.86
Deduct 306 from 320 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 11:
The number 51 fits into 140 2 times, leaving a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 1238422.862
If we subtract 102 from 140, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 12:
380 divided by 51 is 7 with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 1238422.8627
Deduct 357 from 380 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.

Going ahead to step 13:
51 goes into 230 4 times with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 1238422.86274
If we take 204 away from 230, we end up 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.

Moving on to step 14:
When dividing 260 by 51, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 1238422.862745
The remainder is 5 after subtracting 255 from 260.
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 15:
50 divided by 51 is 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 1238422.862745
Deduct 0 from 50 and we're left 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.

Going ahead to step 16:
500 divided by 51 is 9 with a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 1238422.86274509
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.

After the division, we end up with 1238422.86274509 and a remainder of 4.1e-08.
