We're dividing 31508093 by 424 
The aim is to understand the frequency of 424 in 31508093.

Let's proceed to step 1:
When dividing 3 by 424, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 424

Going ahead to step 2:
424 goes into 31 0 times with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Take the next digit (5) from the dividend and append it to 31, then repeat: 315 / 424

On to step 3:
424 can be fit into 315 0 times, resulting in a remainder of 315.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 315 after subtracting 0 from 315.
Take the next digit (0) from the dividend and append it to 315, then repeat: 3150 / 424

Let's proceed to step 4:
When dividing 3150 by 424, we get 7 with a remainder of 182.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 2968 from 3150 to get 182.
Take the next digit (8) from the dividend and append it to 182, then repeat: 1828 / 424

On to step 5:
If we divide 1828 by 424, we get 4 and a remainder of 132.
Put 4 as the next digit of the answer. 
Result so far: 74.0
Deduct 1696 from 1828 and we're left with 132.
Fetch the next digit (0) from the dividend, attach it to 132 and continue: 1320 / 424

Step 6:
424 can be fit into 1320 3 times, resulting in a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 743.0
Deduct 1272 from 1320 and we're left with 48.
Include the next digit (9) from the dividend after 48, then repeat: 489 / 424

Moving on to step 7:
If we divide 489 by 424, we get 1 and a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 7431.0
If we subtract 424 from 489, we get 65.
Take the next digit (3) from the dividend and append it to 65, then repeat: 653 / 424

Let's proceed to step 8:
If we divide 653 by 424, we get 1 and a remainder of 229.
Put 1 as the next digit of the answer. 
Result so far: 74311.0
Subtract 424 from 653 to get 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Let's proceed to step 9:
424 can be fit into 2290 5 times, resulting in a remainder of 170.
The number 5 becomes the next digit in our result. 
Result so far: 74311.5
Subtract 2120 from 2290 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 10:
If we divide 1700 by 424, we get 4 and a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 74311.54
If we subtract 1696 from 1700, we get 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 11:
424 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 74311.54
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
424 can be fit into 400 0 times, resulting in a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 74311.54
The remainder is 400 after subtracting 0 from 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 outcome is 74311.54, with a leftover of 0.004.
