51738539 divided by 684 
The aim is to understand the frequency of 684 in 51738539.

Step 1:
684 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 684

Step 2:
684 can be fit into 51 0 times, resulting in a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Fetch the next digit (7) from the dividend, attach it to 51 and continue: 517 / 684

On to step 3:
If we divide 517 by 684, we get 0 and a remainder of 517.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 517 after subtracting 0 from 517.
Bring next digit (3) of the dividend behind the 517 and repeat the process: 5173 / 684

On to step 4:
684 can be fit into 5173 7 times, resulting in a remainder of 385.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 4788 from 5173, we get 385.
Fetch the next digit (8) from the dividend, attach it to 385 and continue: 3858 / 684

Let's proceed to step 5:
684 goes into 3858 5 times with a remainder of 438.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
Subtracting 3420 from 3858 leaves us with 438.
Grab the next digit (5) from the dividend, add it to 438, then carry on: 4385 / 684

Let's proceed to step 6:
If we divide 4385 by 684, we get 6 and a remainder of 281.
Record the quotient 6 as the next digit in the result. 
Result so far: 756.0
Subtracting 4104 from 4385 leaves us with 281.
Bring next digit (3) of the dividend behind the 281 and repeat the process: 2813 / 684

Advancing to step 7:
When dividing 2813 by 684, we get 4 with a remainder of 77.
Record the quotient 4 as the next digit in the result. 
Result so far: 7564.0
If we subtract 2736 from 2813, we get 77.
Take the next digit (9) from the dividend and append it to 77, then repeat: 779 / 684

Let's proceed to step 8:
684 can be fit into 779 1 times, resulting in a remainder of 95.
Record the quotient 1 as the next digit in the result. 
Result so far: 75641.0
If we subtract 684 from 779, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Let's proceed to step 9:
684 goes into 950 1 times with a remainder of 266.
Use 1 as the next digit of our solution. 
Result so far: 75641.1
Subtract 684 from 950 to get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

On to step 10:
If we divide 2660 by 684, we get 3 and a remainder of 608.
Write down 3 as next digit of the result. 
Result so far: 75641.13
Subtract 2052 from 2660 to get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Going ahead to step 11:
When dividing 6080 by 684, we get 8 with a remainder of 608.
Use 8 as the next digit of our solution. 
Result so far: 75641.138
Subtracting 5472 from 6080 leaves us with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Let's proceed to step 12:
684 goes into 6080 8 times with a remainder of 608.
Use 8 as the next digit of our solution. 
Result so far: 75641.1388
If we subtract 5472 from 6080, we get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

After the division, we end up with 75641.1388 and a remainder of 0.00608.
