898670 ÷ 51 
The aim is to understand the frequency of 51 in 898670.

Let's proceed to step 1:
51 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 51

Step 2:
51 goes into 89 1 times with a remainder of 38.
The next digit of our result is 1. 
Result so far: 1.0
If we take 51 away from 89, we end up with 38.
Bring next digit (8) of the dividend behind the 38 and repeat the process: 388 / 51

Let's proceed to step 3:
If we divide 388 by 51, we get 7 and a remainder of 31.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we subtract 357 from 388, we get 31.
Take the next digit (6) from the dividend and append it to 31, then repeat: 316 / 51

Let's proceed to step 4:
The number 51 fits into 316 6 times, leaving a remainder of 10.
The next digit of our result is 6. 
Result so far: 176.0
Subtracting 306 from 316 leaves us with 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 51

Moving on to step 5:
51 can be fit into 107 2 times, resulting in a remainder of 5.
The next digit of our result is 2. 
Result so far: 1762.0
If we subtract 102 from 107, we get 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 51

Step 6:
51 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 17620.0
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 7:
If we divide 500 by 51, we get 9 and a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 17620.9
Deduct 459 from 500 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 8:
51 goes into 410 8 times with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 17620.98
If we subtract 408 from 410, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 9:
51 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 17620.98
If we subtract 0 from 20, we get 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 10:
200 divided by 51 is 3 with a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 17620.9803
Deduct 153 from 200 and we're left 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.

Moving on to step 11:
51 can be fit into 470 9 times, resulting in a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 17620.98039
The remainder is 11 after subtracting 459 from 470.
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 12:
The number 51 fits into 110 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 17620.980392
The remainder is 8 after subtracting 102 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
51 goes into 80 1 times with a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 17620.9803921
Deduct 51 from 80 and we're left 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.

Going ahead to step 14:
51 goes into 290 5 times with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 17620.98039215
The remainder is 35 after subtracting 255 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 17620.98039215 with a remainder of 3.5e-08.
