We divide 639981 by 93
The aim is to understand the frequency of 93 in 639981.

Advancing to step 1:
The number 93 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 93

Advancing to step 2:
93 goes into 63 0 times with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Bring next digit (9) of the dividend behind the 63 and repeat the process: 639 / 93

Let's proceed to step 3:
When dividing 639 by 93, we get 6 with a remainder of 81.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 558 away from 639, we end up with 81.
Include the next digit (9) from the dividend after 81, then repeat: 819 / 93

Let's proceed to step 4:
93 goes into 819 8 times with a remainder of 75.
Record the quotient 8 as the next digit in the result. 
Result so far: 68.0
If we subtract 744 from 819, we get 75.
Bring next digit (8) of the dividend behind the 75 and repeat the process: 758 / 93

Let's proceed to step 5:
If we divide 758 by 93, we get 8 and a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 688.0
If we subtract 744 from 758, we get 14.
Bring next digit (1) of the dividend behind the 14 and repeat the process: 141 / 93

Let's proceed to step 6:
93 goes into 141 1 times with a remainder of 48.
The next digit of our result is 1. 
Result so far: 6881.0
The remainder is 48 after subtracting 93 from 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 7:
The number 93 fits into 480 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 6881.5
Subtracting 465 from 480 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 8:
When dividing 150 by 93, we get 1 with a remainder of 57.
The next digit of our result is 1. 
Result so far: 6881.51
If we subtract 93 from 150, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 9:
93 can be fit into 570 6 times, resulting in a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 6881.516
Subtracting 558 from 570 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 10:
93 goes into 120 1 times with a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 6881.5161
If we take 93 away from 120, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 11:
If we divide 270 by 93, we get 2 and a remainder of 84.
The next digit of our result is 2. 
Result so far: 6881.51612
Deduct 186 from 270 and we're left with 84.
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 12:
93 goes into 840 9 times with a remainder of 3.
The next digit of our result is 9. 
Result so far: 6881.516129
If we take 837 away from 840, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 13:
If we divide 30 by 93, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 6881.516129
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 14:
93 can be fit into 300 3 times, resulting in a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 6881.51612903
Subtracting 279 from 300 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

In conclusion, the division gives 6881.51612903 with a balance of 2.1e-08.
