816898 ÷ 51 
The aim is to understand the frequency of 51 in 816898.

Advancing to step 1:
51 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 51

Moving on to step 2:
If we divide 81 by 51, we get 1 and a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 51 from 81 to get 30.
Bring next digit (6) of the dividend behind the 30 and repeat the process: 306 / 51

Let's proceed to step 3:
When dividing 306 by 51, we get 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we subtract 306 from 306, we get 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 51

Step 4:
When dividing 8 by 51, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 160.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 51

Advancing to step 5:
The number 51 fits into 89 1 times, leaving a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 1601.0
Subtract 51 from 89 to get 38.
Include the next digit (8) from the dividend after 38, then repeat: 388 / 51

Advancing to step 6:
If we divide 388 by 51, we get 7 and a remainder of 31.
Put 7 as the next digit of the answer. 
Result so far: 16017.0
Subtract 357 from 388 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 7:
310 divided by 51 is 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 16017.6
The remainder is 4 after subtracting 306 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
The number 51 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 16017.6
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
51 goes into 400 7 times with a remainder of 43.
Write down 7 as next digit of the result. 
Result so far: 16017.607
If we subtract 357 from 400, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 10:
The number 51 fits into 430 8 times, leaving a remainder of 22.
The next digit of our result is 8. 
Result so far: 16017.6078
If we take 408 away from 430, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 11:
51 goes into 220 4 times with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 16017.60784
If we subtract 204 from 220, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 12:
If we divide 160 by 51, we get 3 and a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 16017.607843
If we take 153 away from 160, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 13:
70 divided by 51 is 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 16017.6078431
The remainder is 19 after subtracting 51 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 14:
51 can be fit into 190 3 times, resulting in a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 16017.60784313
Deduct 153 from 190 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

The quotient of the division is 16017.60784313, and the remainder is 3.7e-08.
