38924439 divided by 431 
The aim is to understand the frequency of 431 in 38924439.

Step 1:
The number 431 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 431

Step 2:
431 goes into 38 0 times with a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Fetch the next digit (9) from the dividend, attach it to 38 and continue: 389 / 431

Going ahead to step 3:
If we divide 389 by 431, we get 0 and a remainder of 389.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 389 and we're left with 389.
Take the next digit (2) from the dividend and append it to 389, then repeat: 3892 / 431

Advancing to step 4:
The number 431 fits into 3892 9 times, leaving a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 3879 from 3892 leaves us with 13.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 431

Going ahead to step 5:
When dividing 134 by 431, we get 0 with a remainder of 134.
Put 0 as the next digit of the answer. 
Result so far: 90.0
If we subtract 0 from 134, we get 134.
Append the next digit (4) from the dividend to 134 and continue with: 1344 / 431

Let's proceed to step 6:
431 can be fit into 1344 3 times, resulting in a remainder of 51.
Write down 3 as next digit of the result. 
Result so far: 903.0
If we take 1293 away from 1344, we end up with 51.
Grab the next digit (3) from the dividend, add it to 51, then carry on: 513 / 431

Step 7:
431 can be fit into 513 1 times, resulting in a remainder of 82.
The number 1 becomes the next digit in our result. 
Result so far: 9031.0
If we take 431 away from 513, we end up with 82.
Grab the next digit (9) from the dividend, add it to 82, then carry on: 829 / 431

Moving on to step 8:
829 divided by 431 is 1 with a remainder of 398.
The next digit of our result is 1. 
Result so far: 90311.0
Subtracting 431 from 829 leaves us with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Let's proceed to step 9:
431 goes into 3980 9 times with a remainder of 101.
Record the quotient 9 as the next digit in the result. 
Result so far: 90311.9
If we take 3879 away from 3980, we end up with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Advancing to step 10:
1010 divided by 431 is 2 with a remainder of 148.
Put 2 as the next digit of the answer. 
Result so far: 90311.92
Subtracting 862 from 1010 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Advancing to step 11:
When dividing 1480 by 431, we get 3 with a remainder of 187.
The next digit of our result is 3. 
Result so far: 90311.923
If we subtract 1293 from 1480, we get 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

On to step 12:
431 goes into 1870 4 times with a remainder of 146.
Put 4 as the next digit of the answer. 
Result so far: 90311.9234
Subtracting 1724 from 1870 leaves us with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Let's proceed to step 13:
431 goes into 1460 3 times with a remainder of 167.
Put 3 as the next digit of the answer. 
Result so far: 90311.92343
The remainder is 167 after subtracting 1293 from 1460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Going ahead to step 14:
If we divide 1670 by 431, we get 3 and a remainder of 377.
The number 3 becomes the next digit in our result. 
Result so far: 90311.923433
The remainder is 377 after subtracting 1293 from 1670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

The quotient of the division is 90311.923433, and the remainder is 3.77e-05.
