Let's divide 125909 by 89
The aim is to understand the frequency of 89 in 125909.

Going ahead to step 1:
1 divided by 89 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 89

Advancing to step 2:
12 divided by 89 is 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 89

On to step 3:
125 divided by 89 is 1 with a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 89 from 125 and we're left with 36.
Include the next digit (9) from the dividend after 36, then repeat: 369 / 89

Going ahead to step 4:
89 goes into 369 4 times with a remainder of 13.
The next digit of our result is 4. 
Result so far: 14.0
Subtracting 356 from 369 leaves us with 13.
Grab the next digit (0) from the dividend, add it to 13, then carry on: 130 / 89

Advancing to step 5:
89 goes into 130 1 times with a remainder of 41.
Record the quotient 1 as the next digit in the result. 
Result so far: 141.0
The remainder is 41 after subtracting 89 from 130.
Include the next digit (9) from the dividend after 41, then repeat: 419 / 89

Advancing to step 6:
When dividing 419 by 89, we get 4 with a remainder of 63.
Put 4 as the next digit of the answer. 
Result so far: 1414.0
Deduct 356 from 419 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 7:
The number 89 fits into 630 7 times, leaving a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 1414.7
Subtract 623 from 630 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 8:
89 can be fit into 70 0 times, resulting in a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 1414.7
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 9:
The number 89 fits into 700 7 times, leaving a remainder of 77.
The next digit of our result is 7. 
Result so far: 1414.707
If we take 623 away from 700, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 10:
If we divide 770 by 89, we get 8 and a remainder of 58.
Write down 8 as next digit of the result. 
Result so far: 1414.7078
Subtracting 712 from 770 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 11:
The number 89 fits into 580 6 times, leaving a remainder of 46.
Put 6 as the next digit of the answer. 
Result so far: 1414.70786
Subtracting 534 from 580 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 12:
89 can be fit into 460 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 1414.707865
Subtracting 445 from 460 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 13:
150 divided by 89 is 1 with a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 1414.7078651
Deduct 89 from 150 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 14:
The number 89 fits into 610 6 times, leaving a remainder of 76.
Use 6 as the next digit of our solution. 
Result so far: 1414.70786516
The remainder is 76 after subtracting 534 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

After the division, we end up with 1414.70786516 and a remainder of 7.6e-08.
