We look at the division of 25341784 by 290 
The aim is to understand the frequency of 290 in 25341784.

Let's proceed to step 1:
The number 290 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 290

On to step 2:
When dividing 25 by 290, we get 0 with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Bring next digit (3) of the dividend behind the 25 and repeat the process: 253 / 290

Moving on to step 3:
The number 290 fits into 253 0 times, leaving a remainder of 253.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 253, we get 253.
Fetch the next digit (4) from the dividend, attach it to 253 and continue: 2534 / 290

On to step 4:
If we divide 2534 by 290, we get 8 and a remainder of 214.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 2320 from 2534 and we're left with 214.
Fetch the next digit (1) from the dividend, attach it to 214 and continue: 2141 / 290

Let's proceed to step 5:
2141 divided by 290 is 7 with a remainder of 111.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
Subtract 2030 from 2141 to get 111.
Fetch the next digit (7) from the dividend, attach it to 111 and continue: 1117 / 290

On to step 6:
1117 divided by 290 is 3 with a remainder of 247.
Record the quotient 3 as the next digit in the result. 
Result so far: 873.0
Subtracting 870 from 1117 leaves us with 247.
Take the next digit (8) from the dividend and append it to 247, then repeat: 2478 / 290

Let's proceed to step 7:
The number 290 fits into 2478 8 times, leaving a remainder of 158.
Use 8 as the next digit of our solution. 
Result so far: 8738.0
If we subtract 2320 from 2478, we get 158.
Include the next digit (4) from the dividend after 158, then repeat: 1584 / 290

Going ahead to step 8:
290 goes into 1584 5 times with a remainder of 134.
The next digit of our result is 5. 
Result so far: 87385.0
The remainder is 134 after subtracting 1450 from 1584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Moving on to step 9:
290 can be fit into 1340 4 times, resulting in a remainder of 180.
Write down 4 as next digit of the result. 
Result so far: 87385.4
Subtract 1160 from 1340 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 10:
When dividing 1800 by 290, we get 6 with a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 87385.46
Deduct 1740 from 1800 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 11:
290 goes into 600 2 times with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 87385.462
If we subtract 580 from 600, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
290 can be fit into 200 0 times, resulting in a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 87385.462
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 13:
When dividing 2000 by 290, we get 6 with a remainder of 260.
Record the quotient 6 as the next digit in the result. 
Result so far: 87385.46206
Subtract 1740 from 2000 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 14:
290 goes into 2600 8 times with a remainder of 280.
Put 8 as the next digit of the answer. 
Result so far: 87385.462068
Deduct 2320 from 2600 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 15:
290 can be fit into 2800 9 times, resulting in a remainder of 190.
The number 9 becomes the next digit in our result. 
Result so far: 87385.4620689
Subtract 2610 from 2800 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 16:
290 can be fit into 1900 6 times, resulting in a remainder of 160.
The number 6 becomes the next digit in our result. 
Result so far: 87385.46206896
If we subtract 1740 from 1900, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Our division results in 87385.46206896 with a remaining 1.6e-07.
