We look at the division of 43833540 by 684 
The aim is to understand the frequency of 684 in 43833540.

Going ahead to step 1:
684 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 684

Step 2:
If we divide 43 by 684, we get 0 and a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Take the next digit (8) from the dividend and append it to 43, then repeat: 438 / 684

Advancing to step 3:
When dividing 438 by 684, we get 0 with a remainder of 438.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 438 after subtracting 0 from 438.
Append the next digit (3) from the dividend to 438 and continue with: 4383 / 684

Let's proceed to step 4:
When dividing 4383 by 684, we get 6 with a remainder of 279.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 4104 from 4383 to get 279.
Fetch the next digit (3) from the dividend, attach it to 279 and continue: 2793 / 684

Step 5:
684 goes into 2793 4 times with a remainder of 57.
The next digit of our result is 4. 
Result so far: 64.0
If we take 2736 away from 2793, we end up with 57.
Include the next digit (5) from the dividend after 57, then repeat: 575 / 684

Moving on to step 6:
The number 684 fits into 575 0 times, leaving a remainder of 575.
Write down 0 as next digit of the result. 
Result so far: 640.0
If we take 0 away from 575, we end up with 575.
Include the next digit (4) from the dividend after 575, then repeat: 5754 / 684

Advancing to step 7:
When dividing 5754 by 684, we get 8 with a remainder of 282.
Write down 8 as next digit of the result. 
Result so far: 6408.0
Deduct 5472 from 5754 and we're left with 282.
Fetch the next digit (0) from the dividend, attach it to 282 and continue: 2820 / 684

On to step 8:
684 goes into 2820 4 times with a remainder of 84.
Record the quotient 4 as the next digit in the result. 
Result so far: 64084.0
The remainder is 84 after subtracting 2736 from 2820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 9:
684 can be fit into 840 1 times, resulting in a remainder of 156.
The number 1 becomes the next digit in our result. 
Result so far: 64084.1
If we take 684 away from 840, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Step 10:
1560 divided by 684 is 2 with a remainder of 192.
Put 2 as the next digit of the answer. 
Result so far: 64084.12
Deduct 1368 from 1560 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 11:
1920 divided by 684 is 2 with a remainder of 552.
The next digit of our result is 2. 
Result so far: 64084.122
Deduct 1368 from 1920 and we're left with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

The final result is 64084.122 with a remainder of 0.0552.
