We're dividing 31294693 by 813 
The aim is to understand the frequency of 813 in 31294693.

Advancing to step 1:
813 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 813

Moving on to step 2:
813 goes into 31 0 times with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Bring next digit (2) of the dividend behind the 31 and repeat the process: 312 / 813

Moving on to step 3:
813 goes into 312 0 times with a remainder of 312.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 312 leaves us with 312.
Fetch the next digit (9) from the dividend, attach it to 312 and continue: 3129 / 813

Step 4:
813 can be fit into 3129 3 times, resulting in a remainder of 690.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 2439 from 3129, we get 690.
Take the next digit (4) from the dividend and append it to 690, then repeat: 6904 / 813

Moving on to step 5:
813 can be fit into 6904 8 times, resulting in a remainder of 400.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
Subtracting 6504 from 6904 leaves us with 400.
Take the next digit (6) from the dividend and append it to 400, then repeat: 4006 / 813

Let's proceed to step 6:
813 can be fit into 4006 4 times, resulting in a remainder of 754.
The next digit of our result is 4. 
Result so far: 384.0
The remainder is 754 after subtracting 3252 from 4006.
Grab the next digit (9) from the dividend, add it to 754, then carry on: 7549 / 813

Advancing to step 7:
When dividing 7549 by 813, we get 9 with a remainder of 232.
Record the quotient 9 as the next digit in the result. 
Result so far: 3849.0
The remainder is 232 after subtracting 7317 from 7549.
Grab the next digit (3) from the dividend, add it to 232, then carry on: 2323 / 813

Advancing to step 8:
When dividing 2323 by 813, we get 2 with a remainder of 697.
The next digit of our result is 2. 
Result so far: 38492.0
If we subtract 1626 from 2323, we get 697.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6970, and continue the process.

Step 9:
813 goes into 6970 8 times with a remainder of 466.
Use 8 as the next digit of our solution. 
Result so far: 38492.8
Deduct 6504 from 6970 and we're left with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Step 10:
If we divide 4660 by 813, we get 5 and a remainder of 595.
The next digit of our result is 5. 
Result so far: 38492.85
Subtract 4065 from 4660 to get 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

Let's proceed to step 11:
If we divide 5950 by 813, we get 7 and a remainder of 259.
Write down 7 as next digit of the result. 
Result so far: 38492.857
If we take 5691 away from 5950, we end up with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Advancing to step 12:
2590 divided by 813 is 3 with a remainder of 151.
Put 3 as the next digit of the answer. 
Result so far: 38492.8573
Subtracting 2439 from 2590 leaves us with 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Let's proceed to step 13:
The number 813 fits into 1510 1 times, leaving a remainder of 697.
Write down 1 as next digit of the result. 
Result so far: 38492.85731
Deduct 813 from 1510 and we're left with 697.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6970, and continue the process.

Moving on to step 14:
813 can be fit into 6970 8 times, resulting in a remainder of 466.
Write down 8 as next digit of the result. 
Result so far: 38492.857318
The remainder is 466 after subtracting 6504 from 6970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

On to step 15:
813 can be fit into 4660 5 times, resulting in a remainder of 595.
Put 5 as the next digit of the answer. 
Result so far: 38492.8573185
If we take 4065 away from 4660, we end up with 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

Going ahead to step 16:
5950 divided by 813 is 7 with a remainder of 259.
Record the quotient 7 as the next digit in the result. 
Result so far: 38492.85731857
Deduct 5691 from 5950 and we're left with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

The quotient of the division is 38492.85731857, and the remainder is 2.59e-07.
