We're dividing 66461852 by 287 
The aim is to understand the frequency of 287 in 66461852.

Advancing to step 1:
287 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 287

Let's proceed to step 2:
The number 287 fits into 66 0 times, leaving a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Bring next digit (4) of the dividend behind the 66 and repeat the process: 664 / 287

Let's proceed to step 3:
287 goes into 664 2 times with a remainder of 90.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 574 from 664, we get 90.
Bring next digit (6) of the dividend behind the 90 and repeat the process: 906 / 287

Step 4:
If we divide 906 by 287, we get 3 and a remainder of 45.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Deduct 861 from 906 and we're left with 45.
Bring next digit (1) of the dividend behind the 45 and repeat the process: 451 / 287

Advancing to step 5:
287 can be fit into 451 1 times, resulting in a remainder of 164.
The number 1 becomes the next digit in our result. 
Result so far: 231.0
Deduct 287 from 451 and we're left with 164.
Bring next digit (8) of the dividend behind the 164 and repeat the process: 1648 / 287

Going ahead to step 6:
287 goes into 1648 5 times with a remainder of 213.
Record the quotient 5 as the next digit in the result. 
Result so far: 2315.0
If we take 1435 away from 1648, we end up with 213.
Fetch the next digit (5) from the dividend, attach it to 213 and continue: 2135 / 287

Let's proceed to step 7:
The number 287 fits into 2135 7 times, leaving a remainder of 126.
Use 7 as the next digit of our solution. 
Result so far: 23157.0
The remainder is 126 after subtracting 2009 from 2135.
Take the next digit (2) from the dividend and append it to 126, then repeat: 1262 / 287

Going ahead to step 8:
287 can be fit into 1262 4 times, resulting in a remainder of 114.
Write down 4 as next digit of the result. 
Result so far: 231574.0
If we take 1148 away from 1262, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Let's proceed to step 9:
287 can be fit into 1140 3 times, resulting in a remainder of 279.
Put 3 as the next digit of the answer. 
Result so far: 231574.3
Deduct 861 from 1140 and we're left with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

On to step 10:
2790 divided by 287 is 9 with a remainder of 207.
The next digit of our result is 9. 
Result so far: 231574.39
If we subtract 2583 from 2790, we get 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Let's proceed to step 11:
When dividing 2070 by 287, we get 7 with a remainder of 61.
Record the quotient 7 as the next digit in the result. 
Result so far: 231574.397
If we subtract 2009 from 2070, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 12:
When dividing 610 by 287, we get 2 with a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 231574.3972
If we take 574 away from 610, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 13:
The number 287 fits into 360 1 times, leaving a remainder of 73.
Write down 1 as next digit of the result. 
Result so far: 231574.39721
If we take 287 away from 360, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 14:
If we divide 730 by 287, we get 2 and a remainder of 156.
The next digit of our result is 2. 
Result so far: 231574.397212
Subtracting 574 from 730 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Step 15:
287 can be fit into 1560 5 times, resulting in a remainder of 125.
The number 5 becomes the next digit in our result. 
Result so far: 231574.3972125
If we subtract 1435 from 1560, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 16:
If we divide 1250 by 287, we get 4 and a remainder of 102.
Record the quotient 4 as the next digit in the result. 
Result so far: 231574.39721254
If we take 1148 away from 1250, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

The final outcome is 231574.39721254, with a leftover of 1.02e-07.
