We look at the division of 87000561 by 497 
The aim is to understand the frequency of 497 in 87000561.

Moving on to step 1:
If we divide 8 by 497, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 497

Let's proceed to step 2:
When dividing 87 by 497, we get 0 with a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Include the next digit (0) from the dividend after 87, then repeat: 870 / 497

Let's proceed to step 3:
When dividing 870 by 497, we get 1 with a remainder of 373.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 497 from 870, we get 373.
Append the next digit (0) from the dividend to 373 and continue with: 3730 / 497

Step 4:
3730 divided by 497 is 7 with a remainder of 251.
The next digit of our result is 7. 
Result so far: 17.0
If we take 3479 away from 3730, we end up with 251.
Bring next digit (0) of the dividend behind the 251 and repeat the process: 2510 / 497

Moving on to step 5:
When dividing 2510 by 497, we get 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 175.0
The remainder is 25 after subtracting 2485 from 2510.
Take the next digit (5) from the dividend and append it to 25, then repeat: 255 / 497

Moving on to step 6:
497 can be fit into 255 0 times, resulting in a remainder of 255.
Write down 0 as next digit of the result. 
Result so far: 1750.0
Deduct 0 from 255 and we're left with 255.
Fetch the next digit (6) from the dividend, attach it to 255 and continue: 2556 / 497

On to step 7:
When dividing 2556 by 497, we get 5 with a remainder of 71.
The next digit of our result is 5. 
Result so far: 17505.0
The remainder is 71 after subtracting 2485 from 2556.
Bring next digit (1) of the dividend behind the 71 and repeat the process: 711 / 497

Let's proceed to step 8:
497 goes into 711 1 times with a remainder of 214.
Put 1 as the next digit of the answer. 
Result so far: 175051.0
Subtracting 497 from 711 leaves us with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

On to step 9:
If we divide 2140 by 497, we get 4 and a remainder of 152.
The number 4 becomes the next digit in our result. 
Result so far: 175051.4
The remainder is 152 after subtracting 1988 from 2140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Let's proceed to step 10:
The number 497 fits into 1520 3 times, leaving a remainder of 29.
The number 3 becomes the next digit in our result. 
Result so far: 175051.43
Subtract 1491 from 1520 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 11:
If we divide 290 by 497, we get 0 and a remainder of 290.
The number 0 becomes the next digit in our result. 
Result so far: 175051.43
If we take 0 away from 290, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 12:
The number 497 fits into 2900 5 times, leaving a remainder of 415.
Use 5 as the next digit of our solution. 
Result so far: 175051.4305
If we subtract 2485 from 2900, we get 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Advancing to step 13:
497 goes into 4150 8 times with a remainder of 174.
Put 8 as the next digit of the answer. 
Result so far: 175051.43058
Deduct 3976 from 4150 and we're left with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Going ahead to step 14:
If we divide 1740 by 497, we get 3 and a remainder of 249.
Put 3 as the next digit of the answer. 
Result so far: 175051.430583
Deduct 1491 from 1740 and we're left with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Moving on to step 15:
When dividing 2490 by 497, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 175051.4305835
If we subtract 2485 from 2490, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 16:
The number 497 fits into 50 0 times, leaving a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 175051.4305835
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 175051.4305835 with a remaining 5e-08.
