Let's divide 643087 by 54
The aim is to understand the frequency of 54 in 643087.

Moving on to step 1:
54 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 54

On to step 2:
The number 54 fits into 64 1 times, leaving a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 54 away from 64, we end up with 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 54

Advancing to step 3:
103 divided by 54 is 1 with a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 54 from 103 to get 49.
Append the next digit (0) from the dividend to 49 and continue with: 490 / 54

Advancing to step 4:
The number 54 fits into 490 9 times, leaving a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 119.0
Subtracting 486 from 490 leaves us with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 54

Moving on to step 5:
54 goes into 48 0 times with a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 1190.0
If we take 0 away from 48, we end up with 48.
Take the next digit (7) from the dividend and append it to 48, then repeat: 487 / 54

Going ahead to step 6:
When dividing 487 by 54, we get 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 11909.0
The remainder is 1 after subtracting 486 from 487.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
54 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 11909.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
100 divided by 54 is 1 with a remainder of 46.
Put 1 as the next digit of the answer. 
Result so far: 11909.01
Subtracting 54 from 100 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 9:
460 divided by 54 is 8 with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 11909.018
Deduct 432 from 460 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
54 can be fit into 280 5 times, resulting in a remainder of 10.
The next digit of our result is 5. 
Result so far: 11909.0185
If we take 270 away from 280, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
When dividing 100 by 54, we get 1 with a remainder of 46.
Write down 1 as next digit of the result. 
Result so far: 11909.01851
Subtracting 54 from 100 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 12:
If we divide 460 by 54, we get 8 and a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 11909.018518
Deduct 432 from 460 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 13:
54 goes into 280 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 11909.0185185
If we take 270 away from 280, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
54 goes into 100 1 times with a remainder of 46.
Write down 1 as next digit of the result. 
Result so far: 11909.01851851
If we take 54 away from 100, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The quotient of the division is 11909.01851851, and the remainder is 4.6e-08.
