We look at the division of 7628427 by 290 
The aim is to understand the frequency of 290 in 7628427.

Step 1:
When dividing 7 by 290, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 290

On to step 2:
When dividing 76 by 290, we get 0 with a remainder of 76.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 76, we get 76.
Append the next digit (2) from the dividend to 76 and continue with: 762 / 290

Step 3:
290 goes into 762 2 times with a remainder of 182.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 580 away from 762, we end up with 182.
Take the next digit (8) from the dividend and append it to 182, then repeat: 1828 / 290

Moving on to step 4:
290 can be fit into 1828 6 times, resulting in a remainder of 88.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Subtract 1740 from 1828 to get 88.
Fetch the next digit (4) from the dividend, attach it to 88 and continue: 884 / 290

Advancing to step 5:
290 goes into 884 3 times with a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 263.0
Deduct 870 from 884 and we're left with 14.
Bring next digit (2) of the dividend behind the 14 and repeat the process: 142 / 290

Advancing to step 6:
290 can be fit into 142 0 times, resulting in a remainder of 142.
Write down 0 as next digit of the result. 
Result so far: 2630.0
Deduct 0 from 142 and we're left with 142.
Append the next digit (7) from the dividend to 142 and continue with: 1427 / 290

Advancing to step 7:
When dividing 1427 by 290, we get 4 with a remainder of 267.
Write down 4 as next digit of the result. 
Result so far: 26304.0
If we take 1160 away from 1427, we end up with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

On to step 8:
If we divide 2670 by 290, we get 9 and a remainder of 60.
The next digit of our result is 9. 
Result so far: 26304.9
Subtracting 2610 from 2670 leaves us 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.

Moving on to step 9:
290 can be fit into 600 2 times, resulting in a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 26304.92
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.

Step 10:
200 divided by 290 is 0 with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 26304.92
Subtract 0 from 200 to get 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 11:
The number 290 fits into 2000 6 times, leaving a remainder of 260.
The next digit of our result is 6. 
Result so far: 26304.9206
Subtracting 1740 from 2000 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 12:
The number 290 fits into 2600 8 times, leaving a remainder of 280.
Put 8 as the next digit of the answer. 
Result so far: 26304.92068
If we take 2320 away from 2600, we end up 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.

Let's proceed to step 13:
The number 290 fits into 2800 9 times, leaving a remainder of 190.
Record the quotient 9 as the next digit in the result. 
Result so far: 26304.920689
Deduct 2610 from 2800 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.

On to step 14:
When dividing 1900 by 290, we get 6 with a remainder of 160.
Use 6 as the next digit of our solution. 
Result so far: 26304.9206896
Deduct 1740 from 1900 and we're left 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.

Moving on to step 15:
The number 290 fits into 1600 5 times, leaving a remainder of 150.
Put 5 as the next digit of the answer. 
Result so far: 26304.92068965
The remainder is 150 after subtracting 1450 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

After the division, we end up with 26304.92068965 and a remainder of 1.5e-07.
