40251617 divided by 431 
The aim is to understand the frequency of 431 in 40251617.

Step 1:
431 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 431

Going ahead to step 2:
431 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Fetch the next digit (2) from the dividend, attach it to 40 and continue: 402 / 431

Let's proceed to step 3:
When dividing 402 by 431, we get 0 with a remainder of 402.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 402, we end up with 402.
Fetch the next digit (5) from the dividend, attach it to 402 and continue: 4025 / 431

Going ahead to step 4:
4025 divided by 431 is 9 with a remainder of 146.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 3879 from 4025 to get 146.
Take the next digit (1) from the dividend and append it to 146, then repeat: 1461 / 431

Let's proceed to step 5:
1461 divided by 431 is 3 with a remainder of 168.
The number 3 becomes the next digit in our result. 
Result so far: 93.0
Subtract 1293 from 1461 to get 168.
Fetch the next digit (6) from the dividend, attach it to 168 and continue: 1686 / 431

Step 6:
431 goes into 1686 3 times with a remainder of 393.
Put 3 as the next digit of the answer. 
Result so far: 933.0
Subtract 1293 from 1686 to get 393.
Append the next digit (1) from the dividend to 393 and continue with: 3931 / 431

On to step 7:
431 goes into 3931 9 times with a remainder of 52.
The number 9 becomes the next digit in our result. 
Result so far: 9339.0
Subtracting 3879 from 3931 leaves us with 52.
Take the next digit (7) from the dividend and append it to 52, then repeat: 527 / 431

Advancing to step 8:
If we divide 527 by 431, we get 1 and a remainder of 96.
The number 1 becomes the next digit in our result. 
Result so far: 93391.0
Deduct 431 from 527 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 9:
If we divide 960 by 431, we get 2 and a remainder of 98.
The number 2 becomes the next digit in our result. 
Result so far: 93391.2
Deduct 862 from 960 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Let's proceed to step 10:
When dividing 980 by 431, we get 2 with a remainder of 118.
The number 2 becomes the next digit in our result. 
Result so far: 93391.22
Subtracting 862 from 980 leaves us with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

After the division, we end up with 93391.22 and a remainder of 0.118.
