Let's divide 86609860 by 197
The aim is to understand the frequency of 197 in 86609860.

Step 1:
8 divided by 197 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 197

Advancing to step 2:
197 can be fit into 86 0 times, resulting in a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Take the next digit (6) from the dividend and append it to 86, then repeat: 866 / 197

Step 3:
197 goes into 866 4 times with a remainder of 78.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 788 from 866, we get 78.
Append the next digit (0) from the dividend to 78 and continue with: 780 / 197

On to step 4:
The number 197 fits into 780 3 times, leaving a remainder of 189.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Subtract 591 from 780 to get 189.
Include the next digit (9) from the dividend after 189, then repeat: 1899 / 197

Step 5:
1899 divided by 197 is 9 with a remainder of 126.
Write down 9 as next digit of the result. 
Result so far: 439.0
The remainder is 126 after subtracting 1773 from 1899.
Grab the next digit (8) from the dividend, add it to 126, then carry on: 1268 / 197

Advancing to step 6:
The number 197 fits into 1268 6 times, leaving a remainder of 86.
Put 6 as the next digit of the answer. 
Result so far: 4396.0
Deduct 1182 from 1268 and we're left with 86.
Append the next digit (6) from the dividend to 86 and continue with: 866 / 197

On to step 7:
If we divide 866 by 197, we get 4 and a remainder of 78.
Record the quotient 4 as the next digit in the result. 
Result so far: 43964.0
Subtracting 788 from 866 leaves us with 78.
Fetch the next digit (0) from the dividend, attach it to 78 and continue: 780 / 197

Advancing to step 8:
The number 197 fits into 780 3 times, leaving a remainder of 189.
The number 3 becomes the next digit in our result. 
Result so far: 439643.0
Deduct 591 from 780 and we're left with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Let's proceed to step 9:
1890 divided by 197 is 9 with a remainder of 117.
Use 9 as the next digit of our solution. 
Result so far: 439643.9
The remainder is 117 after subtracting 1773 from 1890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

On to step 10:
When dividing 1170 by 197, we get 5 with a remainder of 185.
Write down 5 as next digit of the result. 
Result so far: 439643.95
If we take 985 away from 1170, we end up with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Step 11:
When dividing 1850 by 197, we get 9 with a remainder of 77.
Record the quotient 9 as the next digit in the result. 
Result so far: 439643.959
If we take 1773 away from 1850, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Advancing to step 12:
197 can be fit into 770 3 times, resulting in a remainder of 179.
The next digit of our result is 3. 
Result so far: 439643.9593
The remainder is 179 after subtracting 591 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Let's proceed to step 13:
If we divide 1790 by 197, we get 9 and a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 439643.95939
Subtracting 1773 from 1790 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 14:
The number 197 fits into 170 0 times, leaving a remainder of 170.
Put 0 as the next digit of the answer. 
Result so far: 439643.95939
Subtracting 0 from 170 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 15:
197 can be fit into 1700 8 times, resulting in a remainder of 124.
The number 8 becomes the next digit in our result. 
Result so far: 439643.9593908
Deduct 1576 from 1700 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Going ahead to step 16:
197 goes into 1240 6 times with a remainder of 58.
Write down 6 as next digit of the result. 
Result so far: 439643.95939086
Subtract 1182 from 1240 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

In conclusion, the division gives 439643.95939086 with a balance of 5.8e-08.
