We divide 945389 by 51
The aim is to understand the frequency of 51 in 945389.

Moving on to step 1:
51 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 51

Advancing to step 2:
51 goes into 94 1 times with a remainder of 43.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 51 away from 94, we end up with 43.
Append the next digit (5) from the dividend to 43 and continue with: 435 / 51

Step 3:
If we divide 435 by 51, we get 8 and a remainder of 27.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtract 408 from 435 to get 27.
Fetch the next digit (3) from the dividend, attach it to 27 and continue: 273 / 51

Step 4:
51 can be fit into 273 5 times, resulting in a remainder of 18.
The next digit of our result is 5. 
Result so far: 185.0
Deduct 255 from 273 and we're left with 18.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 51

Let's proceed to step 5:
The number 51 fits into 188 3 times, leaving a remainder of 35.
The next digit of our result is 3. 
Result so far: 1853.0
The remainder is 35 after subtracting 153 from 188.
Take the next digit (9) from the dividend and append it to 35, then repeat: 359 / 51

On to step 6:
51 goes into 359 7 times with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 18537.0
Deduct 357 from 359 and we're left 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 7:
The number 51 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 18537.0
If we take 0 away from 20, we end up 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.

Moving on to step 8:
51 can be fit into 200 3 times, resulting in a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 18537.03
If we take 153 away from 200, we end up 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 9:
The number 51 fits into 470 9 times, leaving a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 18537.039
Subtract 459 from 470 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 10:
The number 51 fits into 110 2 times, leaving a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 18537.0392
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.

Going ahead to step 11:
51 goes into 80 1 times with a remainder of 29.
The next digit of our result is 1. 
Result so far: 18537.03921
If we take 51 away from 80, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 12:
When dividing 290 by 51, we get 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 18537.039215
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 13:
If we divide 350 by 51, we get 6 and a remainder of 44.
The next digit of our result is 6. 
Result so far: 18537.0392156
Subtracting 306 from 350 leaves us 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.

Step 14:
440 divided by 51 is 8 with a remainder of 32.
The next digit of our result is 8. 
Result so far: 18537.03921568
The remainder is 32 after subtracting 408 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 18537.03921568 with a remaining 3.2e-08.
