948558 ÷ 51 
The aim is to understand the frequency of 51 in 948558.

On to step 1:
The number 51 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 51

Advancing to step 2:
If we divide 94 by 51, we get 1 and a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 51 from 94, we get 43.
Include the next digit (8) from the dividend after 43, then repeat: 438 / 51

Step 3:
438 divided by 51 is 8 with a remainder of 30.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtracting 408 from 438 leaves us with 30.
Grab the next digit (5) from the dividend, add it to 30, then carry on: 305 / 51

Moving on to step 4:
305 divided by 51 is 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 185.0
The remainder is 50 after subtracting 255 from 305.
Take the next digit (5) from the dividend and append it to 50, then repeat: 505 / 51

Going ahead to step 5:
If we divide 505 by 51, we get 9 and a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 1859.0
The remainder is 46 after subtracting 459 from 505.
Take the next digit (8) from the dividend and append it to 46, then repeat: 468 / 51

Let's proceed to step 6:
51 goes into 468 9 times with a remainder of 9.
The next digit of our result is 9. 
Result so far: 18599.0
If we subtract 459 from 468, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
90 divided by 51 is 1 with a remainder of 39.
The next digit of our result is 1. 
Result so far: 18599.1
Deduct 51 from 90 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 8:
390 divided by 51 is 7 with a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 18599.17
Subtracting 357 from 390 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 9:
330 divided by 51 is 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 18599.176
The remainder is 24 after subtracting 306 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 10:
51 can be fit into 240 4 times, resulting in a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 18599.1764
If we take 204 away from 240, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 11:
When dividing 360 by 51, we get 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 18599.17647
The remainder is 3 after subtracting 357 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 12:
If we divide 30 by 51, we get 0 and a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 18599.17647
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 13:
300 divided by 51 is 5 with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 18599.1764705
If we subtract 255 from 300, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 14:
51 goes into 450 8 times with a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 18599.17647058
If we subtract 408 from 450, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

In conclusion, the division gives 18599.17647058 with a balance of 4.2e-08.
