45408238 ÷ 812 
The aim is to understand the frequency of 812 in 45408238.

Advancing to step 1:
4 divided by 812 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 812

Let's proceed to step 2:
45 divided by 812 is 0 with a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Fetch the next digit (4) from the dividend, attach it to 45 and continue: 454 / 812

On to step 3:
454 divided by 812 is 0 with a remainder of 454.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 454, we get 454.
Bring next digit (0) of the dividend behind the 454 and repeat the process: 4540 / 812

Going ahead to step 4:
When dividing 4540 by 812, we get 5 with a remainder of 480.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 4060 from 4540 leaves us with 480.
Append the next digit (8) from the dividend to 480 and continue with: 4808 / 812

Let's proceed to step 5:
When dividing 4808 by 812, we get 5 with a remainder of 748.
Write down 5 as next digit of the result. 
Result so far: 55.0
If we subtract 4060 from 4808, we get 748.
Include the next digit (2) from the dividend after 748, then repeat: 7482 / 812

On to step 6:
812 goes into 7482 9 times with a remainder of 174.
The next digit of our result is 9. 
Result so far: 559.0
Subtract 7308 from 7482 to get 174.
Bring next digit (3) of the dividend behind the 174 and repeat the process: 1743 / 812

Step 7:
When dividing 1743 by 812, we get 2 with a remainder of 119.
Use 2 as the next digit of our solution. 
Result so far: 5592.0
Subtract 1624 from 1743 to get 119.
Bring next digit (8) of the dividend behind the 119 and repeat the process: 1198 / 812

Let's proceed to step 8:
1198 divided by 812 is 1 with a remainder of 386.
The number 1 becomes the next digit in our result. 
Result so far: 55921.0
If we take 812 away from 1198, we end up with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Step 9:
If we divide 3860 by 812, we get 4 and a remainder of 612.
The number 4 becomes the next digit in our result. 
Result so far: 55921.4
If we subtract 3248 from 3860, we get 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

On to step 10:
812 goes into 6120 7 times with a remainder of 436.
The next digit of our result is 7. 
Result so far: 55921.47
The remainder is 436 after subtracting 5684 from 6120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Let's proceed to step 11:
4360 divided by 812 is 5 with a remainder of 300.
The next digit of our result is 5. 
Result so far: 55921.475
Deduct 4060 from 4360 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 12:
When dividing 3000 by 812, we get 3 with a remainder of 564.
Record the quotient 3 as the next digit in the result. 
Result so far: 55921.4753
The remainder is 564 after subtracting 2436 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Let's proceed to step 13:
When dividing 5640 by 812, we get 6 with a remainder of 768.
Put 6 as the next digit of the answer. 
Result so far: 55921.47536
If we subtract 4872 from 5640, we get 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

Going ahead to step 14:
812 can be fit into 7680 9 times, resulting in a remainder of 372.
The number 9 becomes the next digit in our result. 
Result so far: 55921.475369
Subtracting 7308 from 7680 leaves us with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

On to step 15:
If we divide 3720 by 812, we get 4 and a remainder of 472.
The next digit of our result is 4. 
Result so far: 55921.4753694
Subtract 3248 from 3720 to get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Step 16:
812 can be fit into 4720 5 times, resulting in a remainder of 660.
Put 5 as the next digit of the answer. 
Result so far: 55921.47536945
Deduct 4060 from 4720 and we're left with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

In conclusion, the division gives 55921.47536945 with a balance of 6.6e-07.
