We're dividing 66918905 by 463 
The aim is to understand the frequency of 463 in 66918905.

Step 1:
463 goes into 6 0 times with 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 / 463

Advancing to step 2:
If we divide 66 by 463, we get 0 and a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Include the next digit (9) from the dividend after 66, then repeat: 669 / 463

Moving on to step 3:
When dividing 669 by 463, we get 1 with a remainder of 206.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 463 from 669 leaves us with 206.
Take the next digit (1) from the dividend and append it to 206, then repeat: 2061 / 463

Advancing to step 4:
2061 divided by 463 is 4 with a remainder of 209.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Deduct 1852 from 2061 and we're left with 209.
Bring next digit (8) of the dividend behind the 209 and repeat the process: 2098 / 463

Let's proceed to step 5:
2098 divided by 463 is 4 with a remainder of 246.
The number 4 becomes the next digit in our result. 
Result so far: 144.0
If we take 1852 away from 2098, we end up with 246.
Take the next digit (9) from the dividend and append it to 246, then repeat: 2469 / 463

Moving on to step 6:
The number 463 fits into 2469 5 times, leaving a remainder of 154.
The number 5 becomes the next digit in our result. 
Result so far: 1445.0
Subtracting 2315 from 2469 leaves us with 154.
Grab the next digit (0) from the dividend, add it to 154, then carry on: 1540 / 463

Advancing to step 7:
463 goes into 1540 3 times with a remainder of 151.
Record the quotient 3 as the next digit in the result. 
Result so far: 14453.0
The remainder is 151 after subtracting 1389 from 1540.
Take the next digit (5) from the dividend and append it to 151, then repeat: 1515 / 463

Step 8:
463 can be fit into 1515 3 times, resulting in a remainder of 126.
Record the quotient 3 as the next digit in the result. 
Result so far: 144533.0
Deduct 1389 from 1515 and we're left with 126.
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 9:
If we divide 1260 by 463, we get 2 and a remainder of 334.
The next digit of our result is 2. 
Result so far: 144533.2
Deduct 926 from 1260 and we're left with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Going ahead to step 10:
The number 463 fits into 3340 7 times, leaving a remainder of 99.
The next digit of our result is 7. 
Result so far: 144533.27
Subtracting 3241 from 3340 leaves us with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

On to step 11:
990 divided by 463 is 2 with a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 144533.272
The remainder is 64 after subtracting 926 from 990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 12:
If we divide 640 by 463, we get 1 and a remainder of 177.
Write down 1 as next digit of the result. 
Result so far: 144533.2721
If we subtract 463 from 640, we get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Let's proceed to step 13:
If we divide 1770 by 463, we get 3 and a remainder of 381.
Put 3 as the next digit of the answer. 
Result so far: 144533.27213
If we subtract 1389 from 1770, we get 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Going ahead to step 14:
3810 divided by 463 is 8 with a remainder of 106.
Write down 8 as next digit of the result. 
Result so far: 144533.272138
If we take 3704 away from 3810, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 15:
If we divide 1060 by 463, we get 2 and a remainder of 134.
Record the quotient 2 as the next digit in the result. 
Result so far: 144533.2721382
Subtracting 926 from 1060 leaves us with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Advancing to step 16:
If we divide 1340 by 463, we get 2 and a remainder of 414.
Use 2 as the next digit of our solution. 
Result so far: 144533.27213822
Subtracting 926 from 1340 leaves us with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

The final result is 144533.27213822 with a remainder of 4.14e-07.
