48408631 divided by 813 
The aim is to understand the frequency of 813 in 48408631.

Going ahead to step 1:
When dividing 4 by 813, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 813

Step 2:
If we divide 48 by 813, we get 0 and a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 48, we get 48.
Append the next digit (4) from the dividend to 48 and continue with: 484 / 813

Moving on to step 3:
If we divide 484 by 813, we get 0 and a remainder of 484.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 484, we get 484.
Include the next digit (0) from the dividend after 484, then repeat: 4840 / 813

Moving on to step 4:
4840 divided by 813 is 5 with a remainder of 775.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 4065 from 4840 and we're left with 775.
Fetch the next digit (8) from the dividend, attach it to 775 and continue: 7758 / 813

Step 5:
If we divide 7758 by 813, we get 9 and a remainder of 441.
Write down 9 as next digit of the result. 
Result so far: 59.0
If we subtract 7317 from 7758, we get 441.
Append the next digit (6) from the dividend to 441 and continue with: 4416 / 813

On to step 6:
813 can be fit into 4416 5 times, resulting in a remainder of 351.
The next digit of our result is 5. 
Result so far: 595.0
If we take 4065 away from 4416, we end up with 351.
Take the next digit (3) from the dividend and append it to 351, then repeat: 3513 / 813

Advancing to step 7:
The number 813 fits into 3513 4 times, leaving a remainder of 261.
Record the quotient 4 as the next digit in the result. 
Result so far: 5954.0
If we subtract 3252 from 3513, we get 261.
Include the next digit (1) from the dividend after 261, then repeat: 2611 / 813

Advancing to step 8:
If we divide 2611 by 813, we get 3 and a remainder of 172.
Record the quotient 3 as the next digit in the result. 
Result so far: 59543.0
If we take 2439 away from 2611, we end up with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

On to step 9:
The number 813 fits into 1720 2 times, leaving a remainder of 94.
The next digit of our result is 2. 
Result so far: 59543.2
If we subtract 1626 from 1720, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 10:
813 can be fit into 940 1 times, resulting in a remainder of 127.
The next digit of our result is 1. 
Result so far: 59543.21
Subtract 813 from 940 to get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Let's proceed to step 11:
The number 813 fits into 1270 1 times, leaving a remainder of 457.
The number 1 becomes the next digit in our result. 
Result so far: 59543.211
If we subtract 813 from 1270, we get 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

The quotient of the division is 59543.211, and the remainder is 0.0457.
