We divide 688021 by 93
The aim is to understand the frequency of 93 in 688021.

Going ahead to step 1:
The number 93 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 93

On to step 2:
If we divide 68 by 93, we get 0 and a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Take the next digit (8) from the dividend and append it to 68, then repeat: 688 / 93

Moving on to step 3:
688 divided by 93 is 7 with a remainder of 37.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 651 from 688 and we're left with 37.
Take the next digit (0) from the dividend and append it to 37, then repeat: 370 / 93

Advancing to step 4:
370 divided by 93 is 3 with a remainder of 91.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
Subtract 279 from 370 to get 91.
Bring next digit (2) of the dividend behind the 91 and repeat the process: 912 / 93

On to step 5:
912 divided by 93 is 9 with a remainder of 75.
Use 9 as the next digit of our solution. 
Result so far: 739.0
The remainder is 75 after subtracting 837 from 912.
Take the next digit (1) from the dividend and append it to 75, then repeat: 751 / 93

Going ahead to step 6:
If we divide 751 by 93, we get 8 and a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 7398.0
Subtracting 744 from 751 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
When dividing 70 by 93, we get 0 with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 7398.0
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 8:
When dividing 700 by 93, we get 7 with a remainder of 49.
The number 7 becomes the next digit in our result. 
Result so far: 7398.07
Subtracting 651 from 700 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 9:
If we divide 490 by 93, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 7398.075
Subtract 465 from 490 to get 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 10:
The number 93 fits into 250 2 times, leaving a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 7398.0752
Subtracting 186 from 250 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 11:
93 can be fit into 640 6 times, resulting in a remainder of 82.
Record the quotient 6 as the next digit in the result. 
Result so far: 7398.07526
Subtract 558 from 640 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 12:
When dividing 820 by 93, we get 8 with a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 7398.075268
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.

Moving on to step 13:
93 can be fit into 760 8 times, resulting in a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 7398.0752688
Deduct 744 from 760 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 7398.0752688 with a remainder of 1.6e-07.
