We're dividing 65381597 by 831 
The aim is to understand the frequency of 831 in 65381597.

Advancing to step 1:
831 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 831

Step 2:
If we divide 65 by 831, we get 0 and a remainder of 65.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 65, we end up with 65.
Take the next digit (3) from the dividend and append it to 65, then repeat: 653 / 831

Let's proceed to step 3:
831 can be fit into 653 0 times, resulting in a remainder of 653.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 653 after subtracting 0 from 653.
Grab the next digit (8) from the dividend, add it to 653, then carry on: 6538 / 831

Moving on to step 4:
831 goes into 6538 7 times with a remainder of 721.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 5817 from 6538, we get 721.
Append the next digit (1) from the dividend to 721 and continue with: 7211 / 831

On to step 5:
7211 divided by 831 is 8 with a remainder of 563.
Write down 8 as next digit of the result. 
Result so far: 78.0
The remainder is 563 after subtracting 6648 from 7211.
Bring next digit (5) of the dividend behind the 563 and repeat the process: 5635 / 831

Step 6:
831 goes into 5635 6 times with a remainder of 649.
Use 6 as the next digit of our solution. 
Result so far: 786.0
Deduct 4986 from 5635 and we're left with 649.
Include the next digit (9) from the dividend after 649, then repeat: 6499 / 831

Advancing to step 7:
The number 831 fits into 6499 7 times, leaving a remainder of 682.
Put 7 as the next digit of the answer. 
Result so far: 7867.0
Subtract 5817 from 6499 to get 682.
Append the next digit (7) from the dividend to 682 and continue with: 6827 / 831

Advancing to step 8:
If we divide 6827 by 831, we get 8 and a remainder of 179.
Put 8 as the next digit of the answer. 
Result so far: 78678.0
Deduct 6648 from 6827 and we're left with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Going ahead to step 9:
When dividing 1790 by 831, we get 2 with a remainder of 128.
The number 2 becomes the next digit in our result. 
Result so far: 78678.2
The remainder is 128 after subtracting 1662 from 1790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 10:
831 goes into 1280 1 times with a remainder of 449.
Put 1 as the next digit of the answer. 
Result so far: 78678.21
If we take 831 away from 1280, we end up with 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Advancing to step 11:
831 goes into 4490 5 times with a remainder of 335.
The next digit of our result is 5. 
Result so far: 78678.215
Deduct 4155 from 4490 and we're left with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Let's proceed to step 12:
When dividing 3350 by 831, we get 4 with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 78678.2154
The remainder is 26 after subtracting 3324 from 3350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 13:
831 goes into 260 0 times with a remainder of 260.
Write down 0 as next digit of the result. 
Result so far: 78678.2154
If we take 0 away from 260, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 14:
831 goes into 2600 3 times with a remainder of 107.
Put 3 as the next digit of the answer. 
Result so far: 78678.215403
If we subtract 2493 from 2600, we get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

On to step 15:
1070 divided by 831 is 1 with a remainder of 239.
The next digit of our result is 1. 
Result so far: 78678.2154031
Deduct 831 from 1070 and we're left with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Step 16:
831 goes into 2390 2 times with a remainder of 728.
Write down 2 as next digit of the result. 
Result so far: 78678.21540312
Subtracting 1662 from 2390 leaves us with 728.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

Our division results in 78678.21540312 with a remaining 7.28e-07.
