We're dividing 76274506 by 813 
The aim is to understand the frequency of 813 in 76274506.

Let's proceed to step 1:
7 divided by 813 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 813

Going ahead to step 2:
The number 813 fits into 76 0 times, leaving a remainder of 76.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 76, we get 76.
Take the next digit (2) from the dividend and append it to 76, then repeat: 762 / 813

Advancing to step 3:
813 goes into 762 0 times with a remainder of 762.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 762, we get 762.
Take the next digit (7) from the dividend and append it to 762, then repeat: 7627 / 813

Advancing to step 4:
813 goes into 7627 9 times with a remainder of 310.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 7317 from 7627, we get 310.
Grab the next digit (4) from the dividend, add it to 310, then carry on: 3104 / 813

Going ahead to step 5:
The number 813 fits into 3104 3 times, leaving a remainder of 665.
The next digit of our result is 3. 
Result so far: 93.0
Deduct 2439 from 3104 and we're left with 665.
Append the next digit (5) from the dividend to 665 and continue with: 6655 / 813

Step 6:
6655 divided by 813 is 8 with a remainder of 151.
Use 8 as the next digit of our solution. 
Result so far: 938.0
Deduct 6504 from 6655 and we're left with 151.
Include the next digit (0) from the dividend after 151, then repeat: 1510 / 813

Let's proceed to step 7:
813 can be fit into 1510 1 times, resulting in a remainder of 697.
Record the quotient 1 as the next digit in the result. 
Result so far: 9381.0
If we subtract 813 from 1510, we get 697.
Include the next digit (6) from the dividend after 697, then repeat: 6976 / 813

On to step 8:
813 goes into 6976 8 times with a remainder of 472.
Write down 8 as next digit of the result. 
Result so far: 93818.0
The remainder is 472 after subtracting 6504 from 6976.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Step 9:
When dividing 4720 by 813, we get 5 with a remainder of 655.
The number 5 becomes the next digit in our result. 
Result so far: 93818.5
Subtract 4065 from 4720 to get 655.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

Moving on to step 10:
If we divide 6550 by 813, we get 8 and a remainder of 46.
The number 8 becomes the next digit in our result. 
Result so far: 93818.58
If we take 6504 away from 6550, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 11:
813 goes into 460 0 times with a remainder of 460.
Use 0 as the next digit of our solution. 
Result so far: 93818.58
If we subtract 0 from 460, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

On to step 12:
The number 813 fits into 4600 5 times, leaving a remainder of 535.
The next digit of our result is 5. 
Result so far: 93818.5805
If we subtract 4065 from 4600, we get 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Going ahead to step 13:
813 can be fit into 5350 6 times, resulting in a remainder of 472.
Record the quotient 6 as the next digit in the result. 
Result so far: 93818.58056
The remainder is 472 after subtracting 4878 from 5350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Step 14:
813 goes into 4720 5 times with a remainder of 655.
Record the quotient 5 as the next digit in the result. 
Result so far: 93818.580565
Deduct 4065 from 4720 and we're left with 655.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

Moving on to step 15:
When dividing 6550 by 813, we get 8 with a remainder of 46.
Use 8 as the next digit of our solution. 
Result so far: 93818.5805658
If we take 6504 away from 6550, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 16:
If we divide 460 by 813, we get 0 and a remainder of 460.
Record the quotient 0 as the next digit in the result. 
Result so far: 93818.5805658
If we subtract 0 from 460, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

The final outcome is 93818.5805658, with a leftover of 4.6e-07.
