We're dividing 35706506 by 209 
The aim is to understand the frequency of 209 in 35706506.

Advancing to step 1:
When dividing 3 by 209, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 209

Advancing to step 2:
35 divided by 209 is 0 with a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Take the next digit (7) from the dividend and append it to 35, then repeat: 357 / 209

Step 3:
When dividing 357 by 209, we get 1 with a remainder of 148.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 209 from 357, we get 148.
Fetch the next digit (0) from the dividend, attach it to 148 and continue: 1480 / 209

Going ahead to step 4:
209 goes into 1480 7 times with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we take 1463 away from 1480, we end up with 17.
Bring next digit (6) of the dividend behind the 17 and repeat the process: 176 / 209

On to step 5:
176 divided by 209 is 0 with a remainder of 176.
The number 0 becomes the next digit in our result. 
Result so far: 170.0
The remainder is 176 after subtracting 0 from 176.
Bring next digit (5) of the dividend behind the 176 and repeat the process: 1765 / 209

Step 6:
If we divide 1765 by 209, we get 8 and a remainder of 93.
Write down 8 as next digit of the result. 
Result so far: 1708.0
If we take 1672 away from 1765, we end up with 93.
Fetch the next digit (0) from the dividend, attach it to 93 and continue: 930 / 209

Moving on to step 7:
209 can be fit into 930 4 times, resulting in a remainder of 94.
Record the quotient 4 as the next digit in the result. 
Result so far: 17084.0
If we subtract 836 from 930, we get 94.
Fetch the next digit (6) from the dividend, attach it to 94 and continue: 946 / 209

Moving on to step 8:
209 can be fit into 946 4 times, resulting in a remainder of 110.
Write down 4 as next digit of the result. 
Result so far: 170844.0
Deduct 836 from 946 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 9:
1100 divided by 209 is 5 with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 170844.5
Subtract 1045 from 1100 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 10:
The number 209 fits into 550 2 times, leaving a remainder of 132.
Record the quotient 2 as the next digit in the result. 
Result so far: 170844.52
Deduct 418 from 550 and we're left 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.

On to step 11:
When dividing 1320 by 209, we get 6 with a remainder of 66.
Put 6 as the next digit of the answer. 
Result so far: 170844.526
If we take 1254 away from 1320, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 12:
When dividing 660 by 209, we get 3 with a remainder of 33.
The next digit of our result is 3. 
Result so far: 170844.5263
If we take 627 away from 660, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 13:
209 goes into 330 1 times with a remainder of 121.
Record the quotient 1 as the next digit in the result. 
Result so far: 170844.52631
Subtracting 209 from 330 leaves us with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Going ahead to step 14:
When dividing 1210 by 209, we get 5 with a remainder of 165.
Put 5 as the next digit of the answer. 
Result so far: 170844.526315
Subtract 1045 from 1210 to get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

On to step 15:
When dividing 1650 by 209, we get 7 with a remainder of 187.
Put 7 as the next digit of the answer. 
Result so far: 170844.5263157
Subtract 1463 from 1650 to get 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

On to step 16:
The number 209 fits into 1870 8 times, leaving a remainder of 198.
Record the quotient 8 as the next digit in the result. 
Result so far: 170844.52631578
If we subtract 1672 from 1870, we get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

The final result is 170844.52631578 with a remainder of 1.98e-07.
