Let's divide 7894821 by 290
The aim is to understand the frequency of 290 in 7894821.

Going ahead to step 1:
290 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 290

Advancing to step 2:
290 goes into 78 0 times with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Include the next digit (9) from the dividend after 78, then repeat: 789 / 290

Let's proceed to step 3:
When dividing 789 by 290, we get 2 with a remainder of 209.
The next digit of our result is 2. 
Result so far: 2.0
If we take 580 away from 789, we end up with 209.
Take the next digit (4) from the dividend and append it to 209, then repeat: 2094 / 290

Advancing to step 4:
290 goes into 2094 7 times with a remainder of 64.
The next digit of our result is 7. 
Result so far: 27.0
The remainder is 64 after subtracting 2030 from 2094.
Append the next digit (8) from the dividend to 64 and continue with: 648 / 290

Going ahead to step 5:
290 goes into 648 2 times with a remainder of 68.
Put 2 as the next digit of the answer. 
Result so far: 272.0
The remainder is 68 after subtracting 580 from 648.
Take the next digit (2) from the dividend and append it to 68, then repeat: 682 / 290

Going ahead to step 6:
When dividing 682 by 290, we get 2 with a remainder of 102.
Use 2 as the next digit of our solution. 
Result so far: 2722.0
If we take 580 away from 682, we end up with 102.
Append the next digit (1) from the dividend to 102 and continue with: 1021 / 290

Advancing to step 7:
1021 divided by 290 is 3 with a remainder of 151.
Record the quotient 3 as the next digit in the result. 
Result so far: 27223.0
If we subtract 870 from 1021, we get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Let's proceed to step 8:
The number 290 fits into 1510 5 times, leaving a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 27223.5
Subtract 1450 from 1510 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
When dividing 600 by 290, we get 2 with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 27223.52
Subtracting 580 from 600 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
The number 290 fits into 200 0 times, leaving a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 27223.52
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 11:
When dividing 2000 by 290, we get 6 with a remainder of 260.
Use 6 as the next digit of our solution. 
Result so far: 27223.5206
If we subtract 1740 from 2000, we 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.

Moving on to step 12:
290 can be fit into 2600 8 times, resulting in a remainder of 280.
The number 8 becomes the next digit in our result. 
Result so far: 27223.52068
Subtracting 2320 from 2600 leaves us 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.

Going ahead to step 13:
When dividing 2800 by 290, we get 9 with a remainder of 190.
The next digit of our result is 9. 
Result so far: 27223.520689
If we take 2610 away from 2800, we end up 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.

On to step 14:
When dividing 1900 by 290, we get 6 with a remainder of 160.
The number 6 becomes the next digit in our result. 
Result so far: 27223.5206896
If we take 1740 away from 1900, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 15:
If we divide 1600 by 290, we get 5 and a remainder of 150.
The number 5 becomes the next digit in our result. 
Result so far: 27223.52068965
Subtracting 1450 from 1600 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

The final result is 27223.52068965 with a remainder of 1.5e-07.
