51689993 divided by 854 
The aim is to understand the frequency of 854 in 51689993.

Advancing to step 1:
The number 854 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 854

Moving on to step 2:
854 goes into 51 0 times with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Fetch the next digit (6) from the dividend, attach it to 51 and continue: 516 / 854

Step 3:
854 goes into 516 0 times with a remainder of 516.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 516 leaves us with 516.
Fetch the next digit (8) from the dividend, attach it to 516 and continue: 5168 / 854

Going ahead to step 4:
854 can be fit into 5168 6 times, resulting in a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 5124 from 5168 and we're left with 44.
Take the next digit (9) from the dividend and append it to 44, then repeat: 449 / 854

On to step 5:
The number 854 fits into 449 0 times, leaving a remainder of 449.
Record the quotient 0 as the next digit in the result. 
Result so far: 60.0
If we subtract 0 from 449, we get 449.
Fetch the next digit (9) from the dividend, attach it to 449 and continue: 4499 / 854

Moving on to step 6:
When dividing 4499 by 854, we get 5 with a remainder of 229.
Record the quotient 5 as the next digit in the result. 
Result so far: 605.0
Deduct 4270 from 4499 and we're left with 229.
Include the next digit (9) from the dividend after 229, then repeat: 2299 / 854

Step 7:
When dividing 2299 by 854, we get 2 with a remainder of 591.
Write down 2 as next digit of the result. 
Result so far: 6052.0
The remainder is 591 after subtracting 1708 from 2299.
Bring next digit (3) of the dividend behind the 591 and repeat the process: 5913 / 854

Let's proceed to step 8:
The number 854 fits into 5913 6 times, leaving a remainder of 789.
The number 6 becomes the next digit in our result. 
Result so far: 60526.0
Subtracting 5124 from 5913 leaves us with 789.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7890, and continue the process.

On to step 9:
The number 854 fits into 7890 9 times, leaving a remainder of 204.
Write down 9 as next digit of the result. 
Result so far: 60526.9
Subtract 7686 from 7890 to get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Let's proceed to step 10:
854 goes into 2040 2 times with a remainder of 332.
Use 2 as the next digit of our solution. 
Result so far: 60526.92
Deduct 1708 from 2040 and we're left with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

On to step 11:
The number 854 fits into 3320 3 times, leaving a remainder of 758.
Put 3 as the next digit of the answer. 
Result so far: 60526.923
The remainder is 758 after subtracting 2562 from 3320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7580, and continue the process.

Going ahead to step 12:
If we divide 7580 by 854, we get 8 and a remainder of 748.
Put 8 as the next digit of the answer. 
Result so far: 60526.9238
Subtract 6832 from 7580 to get 748.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7480, and continue the process.

On to step 13:
When dividing 7480 by 854, we get 8 with a remainder of 648.
Write down 8 as next digit of the result. 
Result so far: 60526.92388
Subtract 6832 from 7480 to get 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

The quotient of the division is 60526.92388, and the remainder is 0.000648.
