We're dividing 620383 by 89 
The aim is to understand the frequency of 89 in 620383.

On to step 1:
89 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 89

Let's proceed to step 2:
89 goes into 62 0 times with a remainder of 62.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 62, we end up with 62.
Append the next digit (0) from the dividend to 62 and continue with: 620 / 89

Moving on to step 3:
The number 89 fits into 620 6 times, leaving a remainder of 86.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 534 from 620 and we're left with 86.
Bring next digit (3) of the dividend behind the 86 and repeat the process: 863 / 89

On to step 4:
If we divide 863 by 89, we get 9 and a remainder of 62.
Use 9 as the next digit of our solution. 
Result so far: 69.0
Subtract 801 from 863 to get 62.
Fetch the next digit (8) from the dividend, attach it to 62 and continue: 628 / 89

Moving on to step 5:
The number 89 fits into 628 7 times, leaving a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 697.0
If we subtract 623 from 628, we get 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 89

On to step 6:
53 divided by 89 is 0 with a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 6970.0
If we subtract 0 from 53, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 7:
530 divided by 89 is 5 with a remainder of 85.
Record the quotient 5 as the next digit in the result. 
Result so far: 6970.5
Deduct 445 from 530 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 8:
89 can be fit into 850 9 times, resulting in a remainder of 49.
The number 9 becomes the next digit in our result. 
Result so far: 6970.59
Deduct 801 from 850 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 9:
490 divided by 89 is 5 with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 6970.595
Deduct 445 from 490 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 10:
450 divided by 89 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 6970.5955
If we subtract 445 from 450, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 6970.5955 with a remaining 5e-05.
