87587278 ÷ 490 
The aim is to understand the frequency of 490 in 87587278.

Let's proceed to step 1:
490 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 490

Advancing to step 2:
The number 490 fits into 87 0 times, leaving a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Bring next digit (5) of the dividend behind the 87 and repeat the process: 875 / 490

On to step 3:
The number 490 fits into 875 1 times, leaving a remainder of 385.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 490 from 875 to get 385.
Include the next digit (8) from the dividend after 385, then repeat: 3858 / 490

Let's proceed to step 4:
The number 490 fits into 3858 7 times, leaving a remainder of 428.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Deduct 3430 from 3858 and we're left with 428.
Include the next digit (7) from the dividend after 428, then repeat: 4287 / 490

Going ahead to step 5:
When dividing 4287 by 490, we get 8 with a remainder of 367.
The next digit of our result is 8. 
Result so far: 178.0
If we subtract 3920 from 4287, we get 367.
Bring next digit (2) of the dividend behind the 367 and repeat the process: 3672 / 490

Let's proceed to step 6:
490 can be fit into 3672 7 times, resulting in a remainder of 242.
The number 7 becomes the next digit in our result. 
Result so far: 1787.0
Subtracting 3430 from 3672 leaves us with 242.
Take the next digit (7) from the dividend and append it to 242, then repeat: 2427 / 490

Let's proceed to step 7:
If we divide 2427 by 490, we get 4 and a remainder of 467.
The number 4 becomes the next digit in our result. 
Result so far: 17874.0
If we take 1960 away from 2427, we end up with 467.
Append the next digit (8) from the dividend to 467 and continue with: 4678 / 490

Moving on to step 8:
490 can be fit into 4678 9 times, resulting in a remainder of 268.
The next digit of our result is 9. 
Result so far: 178749.0
Subtract 4410 from 4678 to get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

On to step 9:
490 can be fit into 2680 5 times, resulting in a remainder of 230.
The number 5 becomes the next digit in our result. 
Result so far: 178749.5
Deduct 2450 from 2680 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 10:
The number 490 fits into 2300 4 times, leaving a remainder of 340.
The next digit of our result is 4. 
Result so far: 178749.54
Subtract 1960 from 2300 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 11:
If we divide 3400 by 490, we get 6 and a remainder of 460.
Put 6 as the next digit of the answer. 
Result so far: 178749.546
Subtracting 2940 from 3400 leaves us with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

On to step 12:
If we divide 4600 by 490, we get 9 and a remainder of 190.
Put 9 as the next digit of the answer. 
Result so far: 178749.5469
Deduct 4410 from 4600 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 13:
490 goes into 1900 3 times with a remainder of 430.
Write down 3 as next digit of the result. 
Result so far: 178749.54693
The remainder is 430 after subtracting 1470 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Step 14:
The number 490 fits into 4300 8 times, leaving a remainder of 380.
Record the quotient 8 as the next digit in the result. 
Result so far: 178749.546938
If we take 3920 away from 4300, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 15:
490 goes into 3800 7 times with a remainder of 370.
Use 7 as the next digit of our solution. 
Result so far: 178749.5469387
If we take 3430 away from 3800, we end up with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 16:
The number 490 fits into 3700 7 times, leaving a remainder of 270.
Use 7 as the next digit of our solution. 
Result so far: 178749.54693877
Subtract 3430 from 3700 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

The final outcome is 178749.54693877, with a leftover of 2.7e-07.
