181364 ÷ 51 
The aim is to understand the frequency of 51 in 181364.

Let's proceed to step 1:
1 divided by 51 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 51

Let's proceed to step 2:
51 goes into 18 0 times with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 51

Going ahead to step 3:
The number 51 fits into 181 3 times, leaving a remainder of 28.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 153 away from 181, we end up with 28.
Fetch the next digit (3) from the dividend, attach it to 28 and continue: 283 / 51

Let's proceed to step 4:
When dividing 283 by 51, we get 5 with a remainder of 28.
Put 5 as the next digit of the answer. 
Result so far: 35.0
Subtract 255 from 283 to get 28.
Bring next digit (6) of the dividend behind the 28 and repeat the process: 286 / 51

Advancing to step 5:
When dividing 286 by 51, we get 5 with a remainder of 31.
Record the quotient 5 as the next digit in the result. 
Result so far: 355.0
Subtract 255 from 286 to get 31.
Fetch the next digit (4) from the dividend, attach it to 31 and continue: 314 / 51

Let's proceed to step 6:
51 can be fit into 314 6 times, resulting in a remainder of 8.
The next digit of our result is 6. 
Result so far: 3556.0
The remainder is 8 after subtracting 306 from 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
51 can be fit into 80 1 times, resulting in a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 3556.1
If we subtract 51 from 80, we 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.

Going ahead to step 8:
The number 51 fits into 290 5 times, leaving a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 3556.15
Subtracting 255 from 290 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 9:
51 can be fit into 350 6 times, resulting in a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 3556.156
Subtract 306 from 350 to get 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 10:
440 divided by 51 is 8 with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 3556.1568
If we take 408 away from 440, we end up 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.

On to step 11:
320 divided by 51 is 6 with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 3556.15686
Subtract 306 from 320 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 12:
If we divide 140 by 51, we get 2 and a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 3556.156862
Subtract 102 from 140 to 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.

On to step 13:
51 can be fit into 380 7 times, resulting in a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 3556.1568627
Subtract 357 from 380 to get 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 14:
51 goes into 230 4 times with a remainder of 26.
The next digit of our result is 4. 
Result so far: 3556.15686274
Deduct 204 from 230 and we're left 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.

After the division, we end up with 3556.15686274 and a remainder of 2.6e-08.
