We divide 78937 by 66
The aim is to understand the frequency of 66 in 78937.

Step 1:
When dividing 7 by 66, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 66

Let's proceed to step 2:
66 can be fit into 78 1 times, resulting in a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 66 away from 78, we end up with 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 66

Advancing to step 3:
66 goes into 129 1 times with a remainder of 63.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 66 from 129, we get 63.
Fetch the next digit (3) from the dividend, attach it to 63 and continue: 633 / 66

Step 4:
If we divide 633 by 66, we get 9 and a remainder of 39.
Write down 9 as next digit of the result. 
Result so far: 119.0
Subtracting 594 from 633 leaves us with 39.
Bring next digit (7) of the dividend behind the 39 and repeat the process: 397 / 66

Let's proceed to step 5:
66 can be fit into 397 6 times, resulting in a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 1196.0
Subtracting 396 from 397 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 6:
The number 66 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 1196.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
66 goes into 100 1 times with a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 1196.01
Subtract 66 from 100 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 8:
66 goes into 340 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 1196.015
If we subtract 330 from 340, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
The number 66 fits into 100 1 times, leaving a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 1196.0151
The remainder is 34 after subtracting 66 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 10:
If we divide 340 by 66, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 1196.01515
Deduct 330 from 340 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.

Going ahead to step 11:
When dividing 100 by 66, we get 1 with a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 1196.015151
If we subtract 66 from 100, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 12:
The number 66 fits into 340 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 1196.0151515
Subtract 330 from 340 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
66 goes into 100 1 times with a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 1196.01515151
Subtract 66 from 100 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

In conclusion, the division gives 1196.01515151 with a balance of 3.4e-08.
