88306343 divided by 439 
The aim is to understand the frequency of 439 in 88306343.

Advancing to step 1:
The number 439 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 439

Step 2:
If we divide 88 by 439, we get 0 and a remainder of 88.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 88, we get 88.
Fetch the next digit (3) from the dividend, attach it to 88 and continue: 883 / 439

Moving on to step 3:
When dividing 883 by 439, we get 2 with a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 878 from 883 leaves us with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 439

Moving on to step 4:
439 goes into 50 0 times with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 20.0
Deduct 0 from 50 and we're left with 50.
Grab the next digit (6) from the dividend, add it to 50, then carry on: 506 / 439

Let's proceed to step 5:
If we divide 506 by 439, we get 1 and a remainder of 67.
The next digit of our result is 1. 
Result so far: 201.0
The remainder is 67 after subtracting 439 from 506.
Bring next digit (3) of the dividend behind the 67 and repeat the process: 673 / 439

On to step 6:
If we divide 673 by 439, we get 1 and a remainder of 234.
Use 1 as the next digit of our solution. 
Result so far: 2011.0
The remainder is 234 after subtracting 439 from 673.
Take the next digit (4) from the dividend and append it to 234, then repeat: 2344 / 439

Let's proceed to step 7:
The number 439 fits into 2344 5 times, leaving a remainder of 149.
Put 5 as the next digit of the answer. 
Result so far: 20115.0
Deduct 2195 from 2344 and we're left with 149.
Grab the next digit (3) from the dividend, add it to 149, then carry on: 1493 / 439

Step 8:
If we divide 1493 by 439, we get 3 and a remainder of 176.
Put 3 as the next digit of the answer. 
Result so far: 201153.0
Subtract 1317 from 1493 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Moving on to step 9:
When dividing 1760 by 439, we get 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 201153.4
Subtracting 1756 from 1760 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
439 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 201153.4
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
439 goes into 400 0 times with a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 201153.4
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final result is 201153.4 with a remainder of 0.04.
