393616 ÷ 89 
The aim is to understand the frequency of 89 in 393616.

Going ahead to step 1:
89 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 89

On to step 2:
If we divide 39 by 89, we get 0 and a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Append the next digit (3) from the dividend to 39 and continue with: 393 / 89

Step 3:
When dividing 393 by 89, we get 4 with a remainder of 37.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 356 away from 393, we end up with 37.
Append the next digit (6) from the dividend to 37 and continue with: 376 / 89

Step 4:
When dividing 376 by 89, we get 4 with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
If we subtract 356 from 376, we get 20.
Grab the next digit (1) from the dividend, add it to 20, then carry on: 201 / 89

Step 5:
When dividing 201 by 89, we get 2 with a remainder of 23.
Use 2 as the next digit of our solution. 
Result so far: 442.0
If we subtract 178 from 201, we get 23.
Append the next digit (6) from the dividend to 23 and continue with: 236 / 89

Going ahead to step 6:
The number 89 fits into 236 2 times, leaving a remainder of 58.
The number 2 becomes the next digit in our result. 
Result so far: 4422.0
The remainder is 58 after subtracting 178 from 236.
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 7:
89 can be fit into 580 6 times, resulting in a remainder of 46.
The number 6 becomes the next digit in our result. 
Result so far: 4422.6
If we take 534 away from 580, we end up 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 8:
89 goes into 460 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 4422.65
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.

Going ahead to step 9:
150 divided by 89 is 1 with a remainder of 61.
Record the quotient 1 as the next digit in the result. 
Result so far: 4422.651
The remainder is 61 after subtracting 89 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 10:
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: 4422.6516
If we subtract 534 from 610, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 11:
89 goes into 760 8 times with a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 4422.65168
Subtract 712 from 760 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 12:
When dividing 480 by 89, we get 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 4422.651685
The remainder is 35 after subtracting 445 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 13:
89 can be fit into 350 3 times, resulting in a remainder of 83.
The number 3 becomes the next digit in our result. 
Result so far: 4422.6516853
If we take 267 away from 350, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Moving on to step 14:
If we divide 830 by 89, we get 9 and a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 4422.65168539
Deduct 801 from 830 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final outcome is 4422.65168539, with a leftover of 2.9e-08.
