Let's divide 15695485 by 209
The aim is to understand the frequency of 209 in 15695485.

Step 1:
209 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 209

Moving on to step 2:
If we divide 15 by 209, we get 0 and a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 209

Advancing to step 3:
The number 209 fits into 156 0 times, leaving a remainder of 156.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 156, we end up with 156.
Bring next digit (9) of the dividend behind the 156 and repeat the process: 1569 / 209

On to step 4:
1569 divided by 209 is 7 with a remainder of 106.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 1463 from 1569 and we're left with 106.
Include the next digit (5) from the dividend after 106, then repeat: 1065 / 209

Going ahead to step 5:
209 goes into 1065 5 times with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
If we subtract 1045 from 1065, we get 20.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 209

Advancing to step 6:
209 can be fit into 204 0 times, resulting in a remainder of 204.
The number 0 becomes the next digit in our result. 
Result so far: 750.0
Subtracting 0 from 204 leaves us with 204.
Bring next digit (8) of the dividend behind the 204 and repeat the process: 2048 / 209

On to step 7:
If we divide 2048 by 209, we get 9 and a remainder of 167.
The next digit of our result is 9. 
Result so far: 7509.0
Subtract 1881 from 2048 to get 167.
Fetch the next digit (5) from the dividend, attach it to 167 and continue: 1675 / 209

Moving on to step 8:
The number 209 fits into 1675 8 times, leaving a remainder of 3.
The next digit of our result is 8. 
Result so far: 75098.0
Subtract 1672 from 1675 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
209 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 75098.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
When dividing 300 by 209, we get 1 with a remainder of 91.
Record the quotient 1 as the next digit in the result. 
Result so far: 75098.01
The remainder is 91 after subtracting 209 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Let's proceed to step 11:
If we divide 910 by 209, we get 4 and a remainder of 74.
Put 4 as the next digit of the answer. 
Result so far: 75098.014
Subtracting 836 from 910 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 12:
The number 209 fits into 740 3 times, leaving a remainder of 113.
Write down 3 as next digit of the result. 
Result so far: 75098.0143
If we take 627 away from 740, we end up with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

On to step 13:
When dividing 1130 by 209, we get 5 with a remainder of 85.
Record the quotient 5 as the next digit in the result. 
Result so far: 75098.01435
Subtracting 1045 from 1130 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 14:
209 can be fit into 850 4 times, resulting in a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 75098.014354
If we subtract 836 from 850, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 15:
When dividing 140 by 209, we get 0 with a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 75098.014354
Subtracting 0 from 140 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 16:
209 can be fit into 1400 6 times, resulting in a remainder of 146.
Write down 6 as next digit of the result. 
Result so far: 75098.01435406
The remainder is 146 after subtracting 1254 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

The final result is 75098.01435406 with a remainder of 1.46e-07.
