Let's divide 34986208 by 831
The aim is to understand the frequency of 831 in 34986208.

Let's proceed to step 1:
If we divide 3 by 831, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 831

On to step 2:
If we divide 34 by 831, we get 0 and a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 34 to get 34.
Bring next digit (9) of the dividend behind the 34 and repeat the process: 349 / 831

On to step 3:
When dividing 349 by 831, we get 0 with a remainder of 349.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 349, we end up with 349.
Fetch the next digit (8) from the dividend, attach it to 349 and continue: 3498 / 831

Advancing to step 4:
3498 divided by 831 is 4 with a remainder of 174.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 3324 away from 3498, we end up with 174.
Append the next digit (6) from the dividend to 174 and continue with: 1746 / 831

Going ahead to step 5:
831 goes into 1746 2 times with a remainder of 84.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
Deduct 1662 from 1746 and we're left with 84.
Include the next digit (2) from the dividend after 84, then repeat: 842 / 831

Moving on to step 6:
831 can be fit into 842 1 times, resulting in a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 421.0
If we subtract 831 from 842, we get 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 831

Going ahead to step 7:
The number 831 fits into 110 0 times, leaving a remainder of 110.
Use 0 as the next digit of our solution. 
Result so far: 4210.0
The remainder is 110 after subtracting 0 from 110.
Include the next digit (8) from the dividend after 110, then repeat: 1108 / 831

Going ahead to step 8:
831 goes into 1108 1 times with a remainder of 277.
Record the quotient 1 as the next digit in the result. 
Result so far: 42101.0
If we subtract 831 from 1108, we get 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

On to step 9:
The number 831 fits into 2770 3 times, leaving a remainder of 277.
Write down 3 as next digit of the result. 
Result so far: 42101.3
Deduct 2493 from 2770 and we're left with 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Moving on to step 10:
831 goes into 2770 3 times with a remainder of 277.
Use 3 as the next digit of our solution. 
Result so far: 42101.33
If we subtract 2493 from 2770, we get 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

The final outcome is 42101.33, with a leftover of 0.277.
