898613 divided by 51 
The aim is to understand the frequency of 51 in 898613.

Let's proceed to step 1:
The number 51 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 51

On to step 2:
If we divide 89 by 51, we get 1 and a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 38 after subtracting 51 from 89.
Fetch the next digit (8) from the dividend, attach it to 38 and continue: 388 / 51

Step 3:
The number 51 fits into 388 7 times, leaving a remainder of 31.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Deduct 357 from 388 and we're left with 31.
Fetch the next digit (6) from the dividend, attach it to 31 and continue: 316 / 51

Going ahead to step 4:
The number 51 fits into 316 6 times, leaving a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 176.0
Subtract 306 from 316 to get 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 51

Moving on to step 5:
When dividing 101 by 51, we get 1 with a remainder of 50.
Use 1 as the next digit of our solution. 
Result so far: 1761.0
Subtract 51 from 101 to get 50.
Grab the next digit (3) from the dividend, add it to 50, then carry on: 503 / 51

Let's proceed to step 6:
If we divide 503 by 51, we get 9 and a remainder of 44.
Use 9 as the next digit of our solution. 
Result so far: 17619.0
The remainder is 44 after subtracting 459 from 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 7:
440 divided by 51 is 8 with a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 17619.8
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 8:
If we divide 320 by 51, we get 6 and a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 17619.86
Deduct 306 from 320 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 9:
51 goes into 140 2 times with a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 17619.862
Subtracting 102 from 140 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 10:
The number 51 fits into 380 7 times, leaving a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 17619.8627
Deduct 357 from 380 and we're left 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.

Moving on to step 11:
If we divide 230 by 51, we get 4 and a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 17619.86274
If we subtract 204 from 230, we get 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 12:
When dividing 260 by 51, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 17619.862745
The remainder is 5 after subtracting 255 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 13:
51 can be fit into 50 0 times, resulting in a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 17619.862745
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 14:
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: 17619.86274509
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.

The final result is 17619.86274509 with a remainder of 4.1e-08.
