Let's divide 886139 by 51
The aim is to understand the frequency of 51 in 886139.

Moving on to step 1:
51 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 51

Going ahead to step 2:
If we divide 88 by 51, we get 1 and a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 37 after subtracting 51 from 88.
Grab the next digit (6) from the dividend, add it to 37, then carry on: 376 / 51

Step 3:
When dividing 376 by 51, we get 7 with a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtract 357 from 376 to get 19.
Include the next digit (1) from the dividend after 19, then repeat: 191 / 51

Advancing to step 4:
51 goes into 191 3 times with a remainder of 38.
The number 3 becomes the next digit in our result. 
Result so far: 173.0
Subtracting 153 from 191 leaves us with 38.
Grab the next digit (3) from the dividend, add it to 38, then carry on: 383 / 51

Advancing to step 5:
The number 51 fits into 383 7 times, leaving a remainder of 26.
The next digit of our result is 7. 
Result so far: 1737.0
If we subtract 357 from 383, we get 26.
Grab the next digit (9) from the dividend, add it to 26, then carry on: 269 / 51

Let's proceed to step 6:
When dividing 269 by 51, we get 5 with a remainder of 14.
The number 5 becomes the next digit in our result. 
Result so far: 17375.0
If we subtract 255 from 269, we 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.

On to step 7:
The number 51 fits into 140 2 times, leaving a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 17375.2
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.

On to step 8:
The number 51 fits into 380 7 times, leaving a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 17375.27
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.

Advancing to step 9:
51 goes into 230 4 times with a remainder of 26.
The next digit of our result is 4. 
Result so far: 17375.274
Subtracting 204 from 230 leaves us 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 10:
If we divide 260 by 51, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 17375.2745
If we subtract 255 from 260, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 11:
51 can be fit into 50 0 times, resulting in a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 17375.2745
If we take 0 away from 50, we end up 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 12:
51 can be fit into 500 9 times, resulting in a remainder of 41.
The next digit of our result is 9. 
Result so far: 17375.274509
The remainder is 41 after subtracting 459 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 13:
51 goes into 410 8 times with a remainder of 2.
The next digit of our result is 8. 
Result so far: 17375.2745098
The remainder is 2 after subtracting 408 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 14:
When dividing 20 by 51, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 17375.2745098
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 17375.2745098 and a remainder of 2e-08.
