45900 ÷ 89 
The aim is to understand the frequency of 89 in 45900.

On to step 1:
89 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 89

Advancing to step 2:
45 divided by 89 is 0 with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Grab the next digit (9) from the dividend, add it to 45, then carry on: 459 / 89

Step 3:
89 can be fit into 459 5 times, resulting in a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 445 away from 459, we end up with 14.
Bring next digit (0) of the dividend behind the 14 and repeat the process: 140 / 89

Moving on to step 4:
If we divide 140 by 89, we get 1 and a remainder of 51.
Write down 1 as next digit of the result. 
Result so far: 51.0
Deduct 89 from 140 and we're left with 51.
Append the next digit (0) from the dividend to 51 and continue with: 510 / 89

Advancing to step 5:
89 goes into 510 5 times with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 515.0
If we take 445 away from 510, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 6:
When dividing 650 by 89, we get 7 with a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 515.7
Subtract 623 from 650 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 7:
When dividing 270 by 89, we get 3 with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 515.73
If we take 267 away from 270, 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.

On to step 8:
When dividing 30 by 89, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 515.73
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.

Advancing to step 9:
300 divided by 89 is 3 with a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 515.7303
If we take 267 away from 300, we end up 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.

Step 10:
When dividing 330 by 89, we get 3 with a remainder of 63.
The next digit of our result is 3. 
Result so far: 515.73033
If we subtract 267 from 330, we get 63.
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 result is 515.73033 with a remainder of 6.3e-05.
