We divide 3992388 by 540
The aim is to understand the frequency of 540 in 3992388.

Advancing to step 1:
The number 540 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 540

Moving on to step 2:
540 can be fit into 39 0 times, resulting in a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Bring next digit (9) of the dividend behind the 39 and repeat the process: 399 / 540

Step 3:
540 goes into 399 0 times with a remainder of 399.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 399, we end up with 399.
Take the next digit (2) from the dividend and append it to 399, then repeat: 3992 / 540

On to step 4:
540 can be fit into 3992 7 times, resulting in a remainder of 212.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 3780 from 3992 leaves us with 212.
Bring next digit (3) of the dividend behind the 212 and repeat the process: 2123 / 540

On to step 5:
540 goes into 2123 3 times with a remainder of 503.
Use 3 as the next digit of our solution. 
Result so far: 73.0
If we take 1620 away from 2123, we end up with 503.
Fetch the next digit (8) from the dividend, attach it to 503 and continue: 5038 / 540

On to step 6:
5038 divided by 540 is 9 with a remainder of 178.
Write down 9 as next digit of the result. 
Result so far: 739.0
Subtracting 4860 from 5038 leaves us with 178.
Append the next digit (8) from the dividend to 178 and continue with: 1788 / 540

Moving on to step 7:
If we divide 1788 by 540, we get 3 and a remainder of 168.
The next digit of our result is 3. 
Result so far: 7393.0
If we take 1620 away from 1788, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Moving on to step 8:
When dividing 1680 by 540, we get 3 with a remainder of 60.
Record the quotient 3 as the next digit in the result. 
Result so far: 7393.3
If we take 1620 away from 1680, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
When dividing 600 by 540, we get 1 with a remainder of 60.
Put 1 as the next digit of the answer. 
Result so far: 7393.31
If we subtract 540 from 600, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
If we divide 600 by 540, we get 1 and a remainder of 60.
Record the quotient 1 as the next digit in the result. 
Result so far: 7393.311
Deduct 540 from 600 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Our division results in 7393.311 with a remaining 0.006.
