We divide 13451542 by 831
The aim is to understand the frequency of 831 in 13451542.

Let's proceed to step 1:
1 divided by 831 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 831

Moving on to step 2:
831 can be fit into 13 0 times, resulting in a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 831

Let's proceed to step 3:
If we divide 134 by 831, we get 0 and a remainder of 134.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 134, we end up with 134.
Take the next digit (5) from the dividend and append it to 134, then repeat: 1345 / 831

On to step 4:
831 goes into 1345 1 times with a remainder of 514.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 831 from 1345 leaves us with 514.
Include the next digit (1) from the dividend after 514, then repeat: 5141 / 831

Going ahead to step 5:
The number 831 fits into 5141 6 times, leaving a remainder of 155.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtracting 4986 from 5141 leaves us with 155.
Include the next digit (5) from the dividend after 155, then repeat: 1555 / 831

On to step 6:
When dividing 1555 by 831, we get 1 with a remainder of 724.
Write down 1 as next digit of the result. 
Result so far: 161.0
If we take 831 away from 1555, we end up with 724.
Grab the next digit (4) from the dividend, add it to 724, then carry on: 7244 / 831

Going ahead to step 7:
7244 divided by 831 is 8 with a remainder of 596.
Use 8 as the next digit of our solution. 
Result so far: 1618.0
The remainder is 596 after subtracting 6648 from 7244.
Append the next digit (2) from the dividend to 596 and continue with: 5962 / 831

Step 8:
831 goes into 5962 7 times with a remainder of 145.
The next digit of our result is 7. 
Result so far: 16187.0
Subtract 5817 from 5962 to get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Moving on to step 9:
831 goes into 1450 1 times with a remainder of 619.
Use 1 as the next digit of our solution. 
Result so far: 16187.1
Subtract 831 from 1450 to get 619.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6190, and continue the process.

Going ahead to step 10:
831 goes into 6190 7 times with a remainder of 373.
The next digit of our result is 7. 
Result so far: 16187.17
The remainder is 373 after subtracting 5817 from 6190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Going ahead to step 11:
When dividing 3730 by 831, we get 4 with a remainder of 406.
Record the quotient 4 as the next digit in the result. 
Result so far: 16187.174
If we take 3324 away from 3730, we end up with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Step 12:
If we divide 4060 by 831, we get 4 and a remainder of 736.
The next digit of our result is 4. 
Result so far: 16187.1744
Subtracting 3324 from 4060 leaves us with 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

The final outcome is 16187.1744, with a leftover of 0.00736.
