88908514 ÷ 423 
The aim is to understand the frequency of 423 in 88908514.

On to step 1:
The number 423 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 423

On to step 2:
88 divided by 423 is 0 with a remainder of 88.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 88 after subtracting 0 from 88.
Take the next digit (9) from the dividend and append it to 88, then repeat: 889 / 423

On to step 3:
889 divided by 423 is 2 with a remainder of 43.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 846 from 889 to get 43.
Include the next digit (0) from the dividend after 43, then repeat: 430 / 423

Step 4:
If we divide 430 by 423, we get 1 and a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 21.0
The remainder is 7 after subtracting 423 from 430.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 423

Let's proceed to step 5:
78 divided by 423 is 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 210.0
Subtract 0 from 78 to get 78.
Grab the next digit (5) from the dividend, add it to 78, then carry on: 785 / 423

Let's proceed to step 6:
423 goes into 785 1 times with a remainder of 362.
Put 1 as the next digit of the answer. 
Result so far: 2101.0
If we take 423 away from 785, we end up with 362.
Fetch the next digit (1) from the dividend, attach it to 362 and continue: 3621 / 423

Moving on to step 7:
3621 divided by 423 is 8 with a remainder of 237.
The next digit of our result is 8. 
Result so far: 21018.0
Subtract 3384 from 3621 to get 237.
Take the next digit (4) from the dividend and append it to 237, then repeat: 2374 / 423

On to step 8:
2374 divided by 423 is 5 with a remainder of 259.
Record the quotient 5 as the next digit in the result. 
Result so far: 210185.0
Deduct 2115 from 2374 and we're left with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Advancing to step 9:
When dividing 2590 by 423, we get 6 with a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 210185.6
Subtract 2538 from 2590 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 10:
The number 423 fits into 520 1 times, leaving a remainder of 97.
Record the quotient 1 as the next digit in the result. 
Result so far: 210185.61
Subtract 423 from 520 to get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Let's proceed to step 11:
The number 423 fits into 970 2 times, leaving a remainder of 124.
The number 2 becomes the next digit in our result. 
Result so far: 210185.612
Subtract 846 from 970 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Moving on to step 12:
When dividing 1240 by 423, we get 2 with a remainder of 394.
The next digit of our result is 2. 
Result so far: 210185.6122
If we take 846 away from 1240, we end up with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

After the division, we end up with 210185.6122 and a remainder of 0.00394.
