31085253 ÷ 824 
The aim is to understand the frequency of 824 in 31085253.

On to step 1:
When dividing 3 by 824, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 824

On to step 2:
824 can be fit into 31 0 times, resulting in a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Append the next digit (0) from the dividend to 31 and continue with: 310 / 824

Step 3:
310 divided by 824 is 0 with a remainder of 310.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 310, we get 310.
Fetch the next digit (8) from the dividend, attach it to 310 and continue: 3108 / 824

Advancing to step 4:
When dividing 3108 by 824, we get 3 with a remainder of 636.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 2472 from 3108 to get 636.
Bring next digit (5) of the dividend behind the 636 and repeat the process: 6365 / 824

Step 5:
824 goes into 6365 7 times with a remainder of 597.
The next digit of our result is 7. 
Result so far: 37.0
Subtract 5768 from 6365 to get 597.
Fetch the next digit (2) from the dividend, attach it to 597 and continue: 5972 / 824

Moving on to step 6:
If we divide 5972 by 824, we get 7 and a remainder of 204.
Put 7 as the next digit of the answer. 
Result so far: 377.0
The remainder is 204 after subtracting 5768 from 5972.
Append the next digit (5) from the dividend to 204 and continue with: 2045 / 824

Advancing to step 7:
824 can be fit into 2045 2 times, resulting in a remainder of 397.
Write down 2 as next digit of the result. 
Result so far: 3772.0
Subtracting 1648 from 2045 leaves us with 397.
Fetch the next digit (3) from the dividend, attach it to 397 and continue: 3973 / 824

Advancing to step 8:
The number 824 fits into 3973 4 times, leaving a remainder of 677.
The number 4 becomes the next digit in our result. 
Result so far: 37724.0
If we subtract 3296 from 3973, we get 677.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6770, and continue the process.

Advancing to step 9:
The number 824 fits into 6770 8 times, leaving a remainder of 178.
Use 8 as the next digit of our solution. 
Result so far: 37724.8
The remainder is 178 after subtracting 6592 from 6770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Advancing to step 10:
1780 divided by 824 is 2 with a remainder of 132.
The next digit of our result is 2. 
Result so far: 37724.82
Subtract 1648 from 1780 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 11:
The number 824 fits into 1320 1 times, leaving a remainder of 496.
The number 1 becomes the next digit in our result. 
Result so far: 37724.821
Subtract 824 from 1320 to get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Let's proceed to step 12:
824 goes into 4960 6 times with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 37724.8216
Subtracting 4944 from 4960 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
160 divided by 824 is 0 with a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 37724.8216
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 14:
1600 divided by 824 is 1 with a remainder of 776.
Use 1 as the next digit of our solution. 
Result so far: 37724.821601
Deduct 824 from 1600 and we're left with 776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7760, and continue the process.

On to step 15:
7760 divided by 824 is 9 with a remainder of 344.
Write down 9 as next digit of the result. 
Result so far: 37724.8216019
The remainder is 344 after subtracting 7416 from 7760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Going ahead to step 16:
The number 824 fits into 3440 4 times, leaving a remainder of 144.
Record the quotient 4 as the next digit in the result. 
Result so far: 37724.82160194
The remainder is 144 after subtracting 3296 from 3440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

After the division, we end up with 37724.82160194 and a remainder of 1.44e-07.
