Let's divide 640144 by 93
The aim is to understand the frequency of 93 in 640144.

Moving on to step 1:
The number 93 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 93

Advancing to step 2:
The number 93 fits into 64 0 times, leaving a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Fetch the next digit (0) from the dividend, attach it to 64 and continue: 640 / 93

Going ahead to step 3:
If we divide 640 by 93, we get 6 and a remainder of 82.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 558 from 640 to get 82.
Take the next digit (1) from the dividend and append it to 82, then repeat: 821 / 93

On to step 4:
93 can be fit into 821 8 times, resulting in a remainder of 77.
The number 8 becomes the next digit in our result. 
Result so far: 68.0
Subtracting 744 from 821 leaves us with 77.
Fetch the next digit (4) from the dividend, attach it to 77 and continue: 774 / 93

Going ahead to step 5:
The number 93 fits into 774 8 times, leaving a remainder of 30.
Put 8 as the next digit of the answer. 
Result so far: 688.0
Subtracting 744 from 774 leaves us with 30.
Fetch the next digit (4) from the dividend, attach it to 30 and continue: 304 / 93

Going ahead to step 6:
The number 93 fits into 304 3 times, leaving a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 6883.0
Deduct 279 from 304 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 7:
When dividing 250 by 93, we get 2 with a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 6883.2
If we subtract 186 from 250, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 8:
When dividing 640 by 93, we get 6 with a remainder of 82.
The next digit of our result is 6. 
Result so far: 6883.26
The remainder is 82 after subtracting 558 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 9:
93 can be fit into 820 8 times, resulting in a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 6883.268
Deduct 744 from 820 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 10:
When dividing 760 by 93, we get 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 6883.2688
The remainder is 16 after subtracting 744 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 6883.2688, and the remainder is 0.00016.
