We're dividing 35078283 by 287 
The aim is to understand the frequency of 287 in 35078283.

Going ahead to step 1:
3 divided by 287 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 287

Step 2:
When dividing 35 by 287, we get 0 with a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Fetch the next digit (0) from the dividend, attach it to 35 and continue: 350 / 287

Moving on to step 3:
When dividing 350 by 287, we get 1 with a remainder of 63.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 287 from 350, we get 63.
Append the next digit (7) from the dividend to 63 and continue with: 637 / 287

On to step 4:
If we divide 637 by 287, we get 2 and a remainder of 63.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 574 from 637 and we're left with 63.
Include the next digit (8) from the dividend after 63, then repeat: 638 / 287

Advancing to step 5:
287 can be fit into 638 2 times, resulting in a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 122.0
Deduct 574 from 638 and we're left with 64.
Fetch the next digit (2) from the dividend, attach it to 64 and continue: 642 / 287

Let's proceed to step 6:
642 divided by 287 is 2 with a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 1222.0
The remainder is 68 after subtracting 574 from 642.
Fetch the next digit (8) from the dividend, attach it to 68 and continue: 688 / 287

Step 7:
If we divide 688 by 287, we get 2 and a remainder of 114.
Use 2 as the next digit of our solution. 
Result so far: 12222.0
If we take 574 away from 688, we end up with 114.
Include the next digit (3) from the dividend after 114, then repeat: 1143 / 287

On to step 8:
When dividing 1143 by 287, we get 3 with a remainder of 282.
Write down 3 as next digit of the result. 
Result so far: 122223.0
If we subtract 861 from 1143, we get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Let's proceed to step 9:
287 can be fit into 2820 9 times, resulting in a remainder of 237.
Write down 9 as next digit of the result. 
Result so far: 122223.9
If we take 2583 away from 2820, we end up with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

On to step 10:
The number 287 fits into 2370 8 times, leaving a remainder of 74.
Write down 8 as next digit of the result. 
Result so far: 122223.98
If we take 2296 away from 2370, we end up 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.

Advancing to step 11:
When dividing 740 by 287, we get 2 with a remainder of 166.
The number 2 becomes the next digit in our result. 
Result so far: 122223.982
If we subtract 574 from 740, we get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Let's proceed to step 12:
287 goes into 1660 5 times with a remainder of 225.
Record the quotient 5 as the next digit in the result. 
Result so far: 122223.9825
Subtract 1435 from 1660 to get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Let's proceed to step 13:
The number 287 fits into 2250 7 times, leaving a remainder of 241.
Write down 7 as next digit of the result. 
Result so far: 122223.98257
The remainder is 241 after subtracting 2009 from 2250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Step 14:
2410 divided by 287 is 8 with a remainder of 114.
Use 8 as the next digit of our solution. 
Result so far: 122223.982578
Subtracting 2296 from 2410 leaves us 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.

Going ahead to step 15:
The number 287 fits into 1140 3 times, leaving a remainder of 279.
The number 3 becomes the next digit in our result. 
Result so far: 122223.9825783
If we subtract 861 from 1140, we get 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Let's proceed to step 16:
287 can be fit into 2790 9 times, resulting in a remainder of 207.
Record the quotient 9 as the next digit in the result. 
Result so far: 122223.98257839
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.

In conclusion, the division gives 122223.98257839 with a balance of 2.07e-07.
