725540 ÷ 89 
The aim is to understand the frequency of 89 in 725540.

Moving on to step 1:
7 divided by 89 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 89

Going ahead to step 2:
72 divided by 89 is 0 with a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Grab the next digit (5) from the dividend, add it to 72, then carry on: 725 / 89

Moving on to step 3:
The number 89 fits into 725 8 times, leaving a remainder of 13.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 712 from 725, we get 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 89

Let's proceed to step 4:
89 can be fit into 135 1 times, resulting in a remainder of 46.
Put 1 as the next digit of the answer. 
Result so far: 81.0
Deduct 89 from 135 and we're left with 46.
Fetch the next digit (4) from the dividend, attach it to 46 and continue: 464 / 89

Step 5:
464 divided by 89 is 5 with a remainder of 19.
Use 5 as the next digit of our solution. 
Result so far: 815.0
If we subtract 445 from 464, we get 19.
Take the next digit (0) from the dividend and append it to 19, then repeat: 190 / 89

Going ahead to step 6:
89 can be fit into 190 2 times, resulting in a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 8152.0
Subtract 178 from 190 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
The number 89 fits into 120 1 times, leaving a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 8152.1
If we take 89 away from 120, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 8:
89 can be fit into 310 3 times, resulting in a remainder of 43.
Write down 3 as next digit of the result. 
Result so far: 8152.13
If we take 267 away from 310, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 9:
89 can be fit into 430 4 times, resulting in a remainder of 74.
Record the quotient 4 as the next digit in the result. 
Result so far: 8152.134
If we take 356 away from 430, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 10:
The number 89 fits into 740 8 times, leaving a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 8152.1348
If we take 712 away from 740, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 11:
When dividing 280 by 89, we get 3 with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 8152.13483
Subtract 267 from 280 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 12:
89 can be fit into 130 1 times, resulting in a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 8152.134831
Subtracting 89 from 130 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 13:
89 can be fit into 410 4 times, resulting in a remainder of 54.
The next digit of our result is 4. 
Result so far: 8152.1348314
Deduct 356 from 410 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 14:
The number 89 fits into 540 6 times, leaving a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 8152.13483146
The remainder is 6 after subtracting 534 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 8152.13483146, with a leftover of 6e-09.
