We look at the division of 75574221 by 290 
The aim is to understand the frequency of 290 in 75574221.

Going ahead to step 1:
When dividing 7 by 290, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 290

Step 2:
290 goes into 75 0 times with a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 75, we end up with 75.
Grab the next digit (5) from the dividend, add it to 75, then carry on: 755 / 290

Going ahead to step 3:
290 can be fit into 755 2 times, resulting in a remainder of 175.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 175 after subtracting 580 from 755.
Take the next digit (7) from the dividend and append it to 175, then repeat: 1757 / 290

On to step 4:
The number 290 fits into 1757 6 times, leaving a remainder of 17.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Deduct 1740 from 1757 and we're left with 17.
Append the next digit (4) from the dividend to 17 and continue with: 174 / 290

Going ahead to step 5:
174 divided by 290 is 0 with a remainder of 174.
Write down 0 as next digit of the result. 
Result so far: 260.0
Subtract 0 from 174 to get 174.
Bring next digit (2) of the dividend behind the 174 and repeat the process: 1742 / 290

Step 6:
290 goes into 1742 6 times with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 2606.0
Subtract 1740 from 1742 to get 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 290

Going ahead to step 7:
If we divide 22 by 290, we get 0 and a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 26060.0
The remainder is 22 after subtracting 0 from 22.
Fetch the next digit (1) from the dividend, attach it to 22 and continue: 221 / 290

Advancing to step 8:
290 can be fit into 221 0 times, resulting in a remainder of 221.
The next digit of our result is 0. 
Result so far: 260600.0
If we take 0 away from 221, we end up with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Let's proceed to step 9:
When dividing 2210 by 290, we get 7 with a remainder of 180.
Use 7 as the next digit of our solution. 
Result so far: 260600.7
Subtract 2030 from 2210 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.

Advancing to step 10:
The number 290 fits into 1800 6 times, leaving a remainder of 60.
The next digit of our result is 6. 
Result so far: 260600.76
The remainder is 60 after subtracting 1740 from 1800.
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 11:
600 divided by 290 is 2 with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 260600.762
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.

Moving on to step 12:
The number 290 fits into 200 0 times, leaving a remainder of 200.
The next digit of our result is 0. 
Result so far: 260600.762
Subtracting 0 from 200 leaves us 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.

Let's proceed to step 13:
290 goes into 2000 6 times with a remainder of 260.
Use 6 as the next digit of our solution. 
Result so far: 260600.76206
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.

Let's proceed to step 14:
290 goes into 2600 8 times with a remainder of 280.
Write down 8 as next digit of the result. 
Result so far: 260600.762068
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.

Going ahead to step 15:
When dividing 2800 by 290, we get 9 with a remainder of 190.
The next digit of our result is 9. 
Result so far: 260600.7620689
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 16:
290 can be fit into 1900 6 times, resulting in a remainder of 160.
Record the quotient 6 as the next digit in the result. 
Result so far: 260600.76206896
Subtract 1740 from 1900 to 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.

The quotient of the division is 260600.76206896, and the remainder is 1.6e-07.
