We're dividing 216978 by 93 
The aim is to understand the frequency of 93 in 216978.

Going ahead to step 1:
When dividing 2 by 93, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 93

Moving on to step 2:
If we divide 21 by 93, we get 0 and a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Grab the next digit (6) from the dividend, add it to 21, then carry on: 216 / 93

Going ahead to step 3:
93 can be fit into 216 2 times, resulting in a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 186 from 216, we get 30.
Bring next digit (9) of the dividend behind the 30 and repeat the process: 309 / 93

Moving on to step 4:
93 goes into 309 3 times with a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 23.0
The remainder is 30 after subtracting 279 from 309.
Grab the next digit (7) from the dividend, add it to 30, then carry on: 307 / 93

Step 5:
The number 93 fits into 307 3 times, leaving a remainder of 28.
The number 3 becomes the next digit in our result. 
Result so far: 233.0
Subtracting 279 from 307 leaves us with 28.
Bring next digit (8) of the dividend behind the 28 and repeat the process: 288 / 93

Advancing to step 6:
93 goes into 288 3 times with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 2333.0
Subtracting 279 from 288 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
When dividing 90 by 93, we get 0 with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 2333.0
If we subtract 0 from 90, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 8:
900 divided by 93 is 9 with a remainder of 63.
The next digit of our result is 9. 
Result so far: 2333.09
Deduct 837 from 900 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 9:
93 goes into 630 6 times with a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 2333.096
The remainder is 72 after subtracting 558 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 10:
The number 93 fits into 720 7 times, leaving a remainder of 69.
The number 7 becomes the next digit in our result. 
Result so far: 2333.0967
If we subtract 651 from 720, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 11:
690 divided by 93 is 7 with a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 2333.09677
Deduct 651 from 690 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The final result is 2333.09677 with a remainder of 3.9e-05.
