We divide 66690702 by 289
The aim is to understand the frequency of 289 in 66690702.

Let's proceed to step 1:
289 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 289

Advancing to step 2:
289 can be fit into 66 0 times, resulting in a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Take the next digit (6) from the dividend and append it to 66, then repeat: 666 / 289

Moving on to step 3:
666 divided by 289 is 2 with a remainder of 88.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 578 from 666 leaves us with 88.
Fetch the next digit (9) from the dividend, attach it to 88 and continue: 889 / 289

Going ahead to step 4:
889 divided by 289 is 3 with a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Deduct 867 from 889 and we're left with 22.
Grab the next digit (0) from the dividend, add it to 22, then carry on: 220 / 289

Step 5:
The number 289 fits into 220 0 times, leaving a remainder of 220.
The next digit of our result is 0. 
Result so far: 230.0
The remainder is 220 after subtracting 0 from 220.
Append the next digit (7) from the dividend to 220 and continue with: 2207 / 289

Let's proceed to step 6:
The number 289 fits into 2207 7 times, leaving a remainder of 184.
Record the quotient 7 as the next digit in the result. 
Result so far: 2307.0
Subtract 2023 from 2207 to get 184.
Fetch the next digit (0) from the dividend, attach it to 184 and continue: 1840 / 289

Let's proceed to step 7:
289 goes into 1840 6 times with a remainder of 106.
Record the quotient 6 as the next digit in the result. 
Result so far: 23076.0
If we subtract 1734 from 1840, we get 106.
Grab the next digit (2) from the dividend, add it to 106, then carry on: 1062 / 289

Step 8:
When dividing 1062 by 289, we get 3 with a remainder of 195.
Write down 3 as next digit of the result. 
Result so far: 230763.0
If we subtract 867 from 1062, we get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Moving on to step 9:
289 can be fit into 1950 6 times, resulting in a remainder of 216.
Put 6 as the next digit of the answer. 
Result so far: 230763.6
If we subtract 1734 from 1950, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Let's proceed to step 10:
If we divide 2160 by 289, we get 7 and a remainder of 137.
The number 7 becomes the next digit in our result. 
Result so far: 230763.67
If we subtract 2023 from 2160, we get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Advancing to step 11:
If we divide 1370 by 289, we get 4 and a remainder of 214.
The next digit of our result is 4. 
Result so far: 230763.674
Subtract 1156 from 1370 to get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Moving on to step 12:
When dividing 2140 by 289, we get 7 with a remainder of 117.
Use 7 as the next digit of our solution. 
Result so far: 230763.6747
Subtract 2023 from 2140 to get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Step 13:
289 goes into 1170 4 times with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 230763.67474
If we take 1156 away from 1170, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 14:
When dividing 140 by 289, we get 0 with a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 230763.67474
Subtracting 0 from 140 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 15:
289 goes into 1400 4 times with a remainder of 244.
Write down 4 as next digit of the result. 
Result so far: 230763.6747404
Deduct 1156 from 1400 and we're left with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Let's proceed to step 16:
289 can be fit into 2440 8 times, resulting in a remainder of 128.
The number 8 becomes the next digit in our result. 
Result so far: 230763.67474048
Deduct 2312 from 2440 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The quotient of the division is 230763.67474048, and the remainder is 1.28e-07.
