We look at the division of 86660821 by 197 
The aim is to understand the frequency of 197 in 86660821.

Advancing to step 1:
197 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 197

On to step 2:
86 divided by 197 is 0 with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Take the next digit (6) from the dividend and append it to 86, then repeat: 866 / 197

Step 3:
197 can be fit into 866 4 times, resulting in a remainder of 78.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 788 from 866 leaves us with 78.
Include the next digit (6) from the dividend after 78, then repeat: 786 / 197

Step 4:
786 divided by 197 is 3 with a remainder of 195.
Write down 3 as next digit of the result. 
Result so far: 43.0
Subtract 591 from 786 to get 195.
Fetch the next digit (0) from the dividend, attach it to 195 and continue: 1950 / 197

Step 5:
When dividing 1950 by 197, we get 9 with a remainder of 177.
Record the quotient 9 as the next digit in the result. 
Result so far: 439.0
The remainder is 177 after subtracting 1773 from 1950.
Grab the next digit (8) from the dividend, add it to 177, then carry on: 1778 / 197

Going ahead to step 6:
The number 197 fits into 1778 9 times, leaving a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 4399.0
Subtracting 1773 from 1778 leaves us with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 197

Going ahead to step 7:
If we divide 52 by 197, we get 0 and a remainder of 52.
Record the quotient 0 as the next digit in the result. 
Result so far: 43990.0
If we take 0 away from 52, we end up with 52.
Append the next digit (1) from the dividend to 52 and continue with: 521 / 197

Let's proceed to step 8:
The number 197 fits into 521 2 times, leaving a remainder of 127.
Put 2 as the next digit of the answer. 
Result so far: 439902.0
If we subtract 394 from 521, we get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Moving on to step 9:
197 goes into 1270 6 times with a remainder of 88.
Use 6 as the next digit of our solution. 
Result so far: 439902.6
The remainder is 88 after subtracting 1182 from 1270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 10:
880 divided by 197 is 4 with a remainder of 92.
Use 4 as the next digit of our solution. 
Result so far: 439902.64
The remainder is 92 after subtracting 788 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 11:
The number 197 fits into 920 4 times, leaving a remainder of 132.
Write down 4 as next digit of the result. 
Result so far: 439902.644
Subtracting 788 from 920 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

The final outcome is 439902.644, with a leftover of 0.0132.
