572434 ÷ 89 
The aim is to understand the frequency of 89 in 572434.

Let's proceed to step 1:
5 divided by 89 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 89

Moving on to step 2:
57 divided by 89 is 0 with a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 57 to get 57.
Take the next digit (2) from the dividend and append it to 57, then repeat: 572 / 89

Advancing to step 3:
572 divided by 89 is 6 with a remainder of 38.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 38 after subtracting 534 from 572.
Bring next digit (4) of the dividend behind the 38 and repeat the process: 384 / 89

Going ahead to step 4:
If we divide 384 by 89, we get 4 and a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
Subtracting 356 from 384 leaves us with 28.
Bring next digit (3) of the dividend behind the 28 and repeat the process: 283 / 89

On to step 5:
The number 89 fits into 283 3 times, leaving a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 643.0
Subtracting 267 from 283 leaves us with 16.
Append the next digit (4) from the dividend to 16 and continue with: 164 / 89

Let's proceed to step 6:
89 can be fit into 164 1 times, resulting in a remainder of 75.
Put 1 as the next digit of the answer. 
Result so far: 6431.0
Subtract 89 from 164 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 7:
89 goes into 750 8 times with a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 6431.8
Deduct 712 from 750 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 8:
89 goes into 380 4 times with a remainder of 24.
The next digit of our result is 4. 
Result so far: 6431.84
Subtract 356 from 380 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 9:
89 goes into 240 2 times with a remainder of 62.
Record the quotient 2 as the next digit in the result. 
Result so far: 6431.842
Subtract 178 from 240 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 10:
When dividing 620 by 89, we get 6 with a remainder of 86.
The next digit of our result is 6. 
Result so far: 6431.8426
The remainder is 86 after subtracting 534 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 11:
If we divide 860 by 89, we get 9 and a remainder of 59.
Write down 9 as next digit of the result. 
Result so far: 6431.84269
Subtracting 801 from 860 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 12:
590 divided by 89 is 6 with a remainder of 56.
Put 6 as the next digit of the answer. 
Result so far: 6431.842696
Subtract 534 from 590 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 13:
89 goes into 560 6 times with a remainder of 26.
Use 6 as the next digit of our solution. 
Result so far: 6431.8426966
If we take 534 away from 560, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The quotient of the division is 6431.8426966, and the remainder is 2.6e-07.
