678138 divided by 97 
The aim is to understand the frequency of 97 in 678138.

Let's proceed to step 1:
97 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 97

Advancing to step 2:
If we divide 67 by 97, we get 0 and a remainder of 67.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 67 leaves us with 67.
Append the next digit (8) from the dividend to 67 and continue with: 678 / 97

On to step 3:
If we divide 678 by 97, we get 6 and a remainder of 96.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 96 after subtracting 582 from 678.
Append the next digit (1) from the dividend to 96 and continue with: 961 / 97

On to step 4:
97 can be fit into 961 9 times, resulting in a remainder of 88.
The next digit of our result is 9. 
Result so far: 69.0
Deduct 873 from 961 and we're left with 88.
Fetch the next digit (3) from the dividend, attach it to 88 and continue: 883 / 97

Going ahead to step 5:
97 can be fit into 883 9 times, resulting in a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 699.0
Subtracting 873 from 883 leaves us with 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 97

On to step 6:
The number 97 fits into 108 1 times, leaving a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 6991.0
If we subtract 97 from 108, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
When dividing 110 by 97, we get 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 6991.1
The remainder is 13 after subtracting 97 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 8:
97 can be fit into 130 1 times, resulting in a remainder of 33.
Use 1 as the next digit of our solution. 
Result so far: 6991.11
If we subtract 97 from 130, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

The final outcome is 6991.11, with a leftover of 0.033.
