We look at the division of 89413460 by 813 
The aim is to understand the frequency of 813 in 89413460.

Moving on to step 1:
When dividing 8 by 813, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 813

Advancing to step 2:
When dividing 89 by 813, we get 0 with a remainder of 89.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 89 and we're left with 89.
Include the next digit (4) from the dividend after 89, then repeat: 894 / 813

Going ahead to step 3:
894 divided by 813 is 1 with a remainder of 81.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 813 from 894 and we're left with 81.
Fetch the next digit (1) from the dividend, attach it to 81 and continue: 811 / 813

Advancing to step 4:
The number 813 fits into 811 0 times, leaving a remainder of 811.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 811, we end up with 811.
Bring next digit (3) of the dividend behind the 811 and repeat the process: 8113 / 813

Step 5:
If we divide 8113 by 813, we get 9 and a remainder of 796.
Write down 9 as next digit of the result. 
Result so far: 109.0
If we subtract 7317 from 8113, we get 796.
Grab the next digit (4) from the dividend, add it to 796, then carry on: 7964 / 813

Moving on to step 6:
7964 divided by 813 is 9 with a remainder of 647.
Write down 9 as next digit of the result. 
Result so far: 1099.0
Subtracting 7317 from 7964 leaves us with 647.
Append the next digit (6) from the dividend to 647 and continue with: 6476 / 813

Going ahead to step 7:
6476 divided by 813 is 7 with a remainder of 785.
Put 7 as the next digit of the answer. 
Result so far: 10997.0
If we take 5691 away from 6476, we end up with 785.
Bring next digit (0) of the dividend behind the 785 and repeat the process: 7850 / 813

Moving on to step 8:
7850 divided by 813 is 9 with a remainder of 533.
Write down 9 as next digit of the result. 
Result so far: 109979.0
The remainder is 533 after subtracting 7317 from 7850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

Moving on to step 9:
If we divide 5330 by 813, we get 6 and a remainder of 452.
Record the quotient 6 as the next digit in the result. 
Result so far: 109979.6
Subtracting 4878 from 5330 leaves us with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Moving on to step 10:
813 goes into 4520 5 times with a remainder of 455.
Record the quotient 5 as the next digit in the result. 
Result so far: 109979.65
The remainder is 455 after subtracting 4065 from 4520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Moving on to step 11:
If we divide 4550 by 813, we get 5 and a remainder of 485.
Put 5 as the next digit of the answer. 
Result so far: 109979.655
Subtract 4065 from 4550 to get 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

The final result is 109979.655 with a remainder of 0.0485.
