66101687 divided by 229 
The aim is to understand the frequency of 229 in 66101687.

Advancing to step 1:
If we divide 6 by 229, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 229

Going ahead to step 2:
If we divide 66 by 229, we get 0 and a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Include the next digit (1) from the dividend after 66, then repeat: 661 / 229

Step 3:
When dividing 661 by 229, we get 2 with a remainder of 203.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 203 after subtracting 458 from 661.
Grab the next digit (0) from the dividend, add it to 203, then carry on: 2030 / 229

Going ahead to step 4:
2030 divided by 229 is 8 with a remainder of 198.
Write down 8 as next digit of the result. 
Result so far: 28.0
Deduct 1832 from 2030 and we're left with 198.
Append the next digit (1) from the dividend to 198 and continue with: 1981 / 229

Step 5:
229 can be fit into 1981 8 times, resulting in a remainder of 149.
Put 8 as the next digit of the answer. 
Result so far: 288.0
The remainder is 149 after subtracting 1832 from 1981.
Grab the next digit (6) from the dividend, add it to 149, then carry on: 1496 / 229

Advancing to step 6:
If we divide 1496 by 229, we get 6 and a remainder of 122.
Put 6 as the next digit of the answer. 
Result so far: 2886.0
If we take 1374 away from 1496, we end up with 122.
Bring next digit (8) of the dividend behind the 122 and repeat the process: 1228 / 229

Moving on to step 7:
The number 229 fits into 1228 5 times, leaving a remainder of 83.
The next digit of our result is 5. 
Result so far: 28865.0
If we subtract 1145 from 1228, we get 83.
Fetch the next digit (7) from the dividend, attach it to 83 and continue: 837 / 229

Advancing to step 8:
229 can be fit into 837 3 times, resulting in a remainder of 150.
Write down 3 as next digit of the result. 
Result so far: 288653.0
The remainder is 150 after subtracting 687 from 837.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 9:
When dividing 1500 by 229, we get 6 with a remainder of 126.
Write down 6 as next digit of the result. 
Result so far: 288653.6
The remainder is 126 after subtracting 1374 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Let's proceed to step 10:
When dividing 1260 by 229, we get 5 with a remainder of 115.
Write down 5 as next digit of the result. 
Result so far: 288653.65
The remainder is 115 after subtracting 1145 from 1260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 11:
If we divide 1150 by 229, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 288653.655
The remainder is 5 after subtracting 1145 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 288653.655 with a remainder of 0.0005.
