We look at the division of 31753523 by 812 
The aim is to understand the frequency of 812 in 31753523.

On to step 1:
When dividing 3 by 812, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 812

Advancing to step 2:
When dividing 31 by 812, we get 0 with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Append the next digit (7) from the dividend to 31 and continue with: 317 / 812

Advancing to step 3:
The number 812 fits into 317 0 times, leaving a remainder of 317.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 317 and we're left with 317.
Bring next digit (5) of the dividend behind the 317 and repeat the process: 3175 / 812

Moving on to step 4:
812 goes into 3175 3 times with a remainder of 739.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 739 after subtracting 2436 from 3175.
Append the next digit (3) from the dividend to 739 and continue with: 7393 / 812

Advancing to step 5:
The number 812 fits into 7393 9 times, leaving a remainder of 85.
Use 9 as the next digit of our solution. 
Result so far: 39.0
The remainder is 85 after subtracting 7308 from 7393.
Take the next digit (5) from the dividend and append it to 85, then repeat: 855 / 812

Advancing to step 6:
855 divided by 812 is 1 with a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 391.0
Subtract 812 from 855 to get 43.
Append the next digit (2) from the dividend to 43 and continue with: 432 / 812

On to step 7:
The number 812 fits into 432 0 times, leaving a remainder of 432.
The next digit of our result is 0. 
Result so far: 3910.0
If we subtract 0 from 432, we get 432.
Fetch the next digit (3) from the dividend, attach it to 432 and continue: 4323 / 812

Moving on to step 8:
4323 divided by 812 is 5 with a remainder of 263.
Write down 5 as next digit of the result. 
Result so far: 39105.0
If we subtract 4060 from 4323, we get 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Step 9:
812 goes into 2630 3 times with a remainder of 194.
Use 3 as the next digit of our solution. 
Result so far: 39105.3
The remainder is 194 after subtracting 2436 from 2630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Let's proceed to step 10:
812 goes into 1940 2 times with a remainder of 316.
Record the quotient 2 as the next digit in the result. 
Result so far: 39105.32
Subtracting 1624 from 1940 leaves us with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Advancing to step 11:
If we divide 3160 by 812, we get 3 and a remainder of 724.
Put 3 as the next digit of the answer. 
Result so far: 39105.323
Subtracting 2436 from 3160 leaves us with 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

Let's proceed to step 12:
7240 divided by 812 is 8 with a remainder of 744.
The next digit of our result is 8. 
Result so far: 39105.3238
If we take 6496 away from 7240, we end up with 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

On to step 13:
812 goes into 7440 9 times with a remainder of 132.
Put 9 as the next digit of the answer. 
Result so far: 39105.32389
Deduct 7308 from 7440 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Advancing to step 14:
If we divide 1320 by 812, we get 1 and a remainder of 508.
Write down 1 as next digit of the result. 
Result so far: 39105.323891
Deduct 812 from 1320 and we're left with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Going ahead to step 15:
812 goes into 5080 6 times with a remainder of 208.
Record the quotient 6 as the next digit in the result. 
Result so far: 39105.3238916
Subtract 4872 from 5080 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 16:
812 can be fit into 2080 2 times, resulting in a remainder of 456.
Put 2 as the next digit of the answer. 
Result so far: 39105.32389162
Deduct 1624 from 2080 and we're left with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Our division results in 39105.32389162 with a remaining 4.56e-07.
