We divide 637243 by 89
The aim is to understand the frequency of 89 in 637243.

Let's proceed to step 1:
6 divided by 89 is 0 with 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.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 89

On to step 2:
63 divided by 89 is 0 with a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Grab the next digit (7) from the dividend, add it to 63, then carry on: 637 / 89

Advancing to step 3:
89 can be fit into 637 7 times, resulting in a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 623 from 637, we get 14.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 89

On to step 4:
If we divide 142 by 89, we get 1 and a remainder of 53.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
Subtracting 89 from 142 leaves us with 53.
Include the next digit (4) from the dividend after 53, then repeat: 534 / 89

Going ahead to step 5:
When dividing 534 by 89, we get 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 716.0
Subtract 534 from 534 to get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 89

Let's proceed to step 6:
The number 89 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 7160.0
If we take 0 away from 3, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
89 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 7160.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
The number 89 fits into 300 3 times, leaving a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 7160.03
Subtracting 267 from 300 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 9:
The number 89 fits into 330 3 times, leaving a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 7160.033
The remainder is 63 after subtracting 267 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

The final outcome is 7160.033, with a leftover of 0.0063.
