Let's divide 66919961 by 290
The aim is to understand the frequency of 290 in 66919961.

Moving on to step 1:
The number 290 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 290

Let's proceed to step 2:
66 divided by 290 is 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Fetch the next digit (9) from the dividend, attach it to 66 and continue: 669 / 290

On to step 3:
If we divide 669 by 290, we get 2 and a remainder of 89.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 580 from 669 to get 89.
Take the next digit (1) from the dividend and append it to 89, then repeat: 891 / 290

Moving on to step 4:
891 divided by 290 is 3 with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Subtract 870 from 891 to get 21.
Grab the next digit (9) from the dividend, add it to 21, then carry on: 219 / 290

Step 5:
The number 290 fits into 219 0 times, leaving a remainder of 219.
Record the quotient 0 as the next digit in the result. 
Result so far: 230.0
If we subtract 0 from 219, we get 219.
Fetch the next digit (9) from the dividend, attach it to 219 and continue: 2199 / 290

Moving on to step 6:
If we divide 2199 by 290, we get 7 and a remainder of 169.
Write down 7 as next digit of the result. 
Result so far: 2307.0
Deduct 2030 from 2199 and we're left with 169.
Include the next digit (6) from the dividend after 169, then repeat: 1696 / 290

Advancing to step 7:
The number 290 fits into 1696 5 times, leaving a remainder of 246.
The next digit of our result is 5. 
Result so far: 23075.0
Subtracting 1450 from 1696 leaves us with 246.
Take the next digit (1) from the dividend and append it to 246, then repeat: 2461 / 290

Let's proceed to step 8:
2461 divided by 290 is 8 with a remainder of 141.
The next digit of our result is 8. 
Result so far: 230758.0
Subtracting 2320 from 2461 leaves us with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Moving on to step 9:
290 goes into 1410 4 times with a remainder of 250.
The next digit of our result is 4. 
Result so far: 230758.4
The remainder is 250 after subtracting 1160 from 1410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 10:
2500 divided by 290 is 8 with a remainder of 180.
Write down 8 as next digit of the result. 
Result so far: 230758.48
Subtract 2320 from 2500 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.

Going ahead to step 11:
The number 290 fits into 1800 6 times, leaving a remainder of 60.
The next digit of our result is 6. 
Result so far: 230758.486
Subtract 1740 from 1800 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 12:
290 goes into 600 2 times with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 230758.4862
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.

Let's proceed to step 13:
200 divided by 290 is 0 with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 230758.4862
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.

Step 14:
When dividing 2000 by 290, we get 6 with a remainder of 260.
Put 6 as the next digit of the answer. 
Result so far: 230758.486206
Deduct 1740 from 2000 and we're left 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.

Advancing to step 15:
290 can be fit into 2600 8 times, resulting in a remainder of 280.
The next digit of our result is 8. 
Result so far: 230758.4862068
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 16:
The number 290 fits into 2800 9 times, leaving a remainder of 190.
Write down 9 as next digit of the result. 
Result so far: 230758.48620689
The remainder is 190 after subtracting 2610 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

In conclusion, the division gives 230758.48620689 with a balance of 1.9e-07.
