Let's divide 40029331 by 831
The aim is to understand the frequency of 831 in 40029331.

Moving on to step 1:
When dividing 4 by 831, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 831

Going ahead to step 2:
When dividing 40 by 831, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Grab the next digit (0) from the dividend, add it to 40, then carry on: 400 / 831

Advancing to step 3:
When dividing 400 by 831, we get 0 with a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 400 leaves us with 400.
Include the next digit (2) from the dividend after 400, then repeat: 4002 / 831

Step 4:
The number 831 fits into 4002 4 times, leaving a remainder of 678.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 3324 from 4002, we get 678.
Grab the next digit (9) from the dividend, add it to 678, then carry on: 6789 / 831

Step 5:
The number 831 fits into 6789 8 times, leaving a remainder of 141.
Use 8 as the next digit of our solution. 
Result so far: 48.0
Subtracting 6648 from 6789 leaves us with 141.
Fetch the next digit (3) from the dividend, attach it to 141 and continue: 1413 / 831

Going ahead to step 6:
1413 divided by 831 is 1 with a remainder of 582.
Write down 1 as next digit of the result. 
Result so far: 481.0
The remainder is 582 after subtracting 831 from 1413.
Fetch the next digit (3) from the dividend, attach it to 582 and continue: 5823 / 831

Advancing to step 7:
831 can be fit into 5823 7 times, resulting in a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 4817.0
Subtracting 5817 from 5823 leaves us with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 831

On to step 8:
61 divided by 831 is 0 with a remainder of 61.
Use 0 as the next digit of our solution. 
Result so far: 48170.0
Subtract 0 from 61 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 9:
The number 831 fits into 610 0 times, leaving a remainder of 610.
The next digit of our result is 0. 
Result so far: 48170.0
If we subtract 0 from 610, we get 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Let's proceed to step 10:
If we divide 6100 by 831, we get 7 and a remainder of 283.
Use 7 as the next digit of our solution. 
Result so far: 48170.07
The remainder is 283 after subtracting 5817 from 6100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Let's proceed to step 11:
If we divide 2830 by 831, we get 3 and a remainder of 337.
The number 3 becomes the next digit in our result. 
Result so far: 48170.073
The remainder is 337 after subtracting 2493 from 2830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Advancing to step 12:
The number 831 fits into 3370 4 times, leaving a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 48170.0734
If we take 3324 away from 3370, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 13:
460 divided by 831 is 0 with a remainder of 460.
Put 0 as the next digit of the answer. 
Result so far: 48170.0734
The remainder is 460 after subtracting 0 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

On to step 14:
The number 831 fits into 4600 5 times, leaving a remainder of 445.
Write down 5 as next digit of the result. 
Result so far: 48170.073405
Subtract 4155 from 4600 to get 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Going ahead to step 15:
4450 divided by 831 is 5 with a remainder of 295.
Use 5 as the next digit of our solution. 
Result so far: 48170.0734055
Subtract 4155 from 4450 to get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Our division results in 48170.0734055 with a remaining 2.95e-06.
