20317615 ÷ 913 
The aim is to understand the frequency of 913 in 20317615.

Advancing to step 1:
The number 913 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 913

Moving on to step 2:
If we divide 20 by 913, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Take the next digit (3) from the dividend and append it to 20, then repeat: 203 / 913

Going ahead to step 3:
203 divided by 913 is 0 with a remainder of 203.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 203 after subtracting 0 from 203.
Include the next digit (1) from the dividend after 203, then repeat: 2031 / 913

On to step 4:
The number 913 fits into 2031 2 times, leaving a remainder of 205.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 1826 from 2031 to get 205.
Grab the next digit (7) from the dividend, add it to 205, then carry on: 2057 / 913

Step 5:
The number 913 fits into 2057 2 times, leaving a remainder of 231.
The next digit of our result is 2. 
Result so far: 22.0
Subtracting 1826 from 2057 leaves us with 231.
Take the next digit (6) from the dividend and append it to 231, then repeat: 2316 / 913

Moving on to step 6:
2316 divided by 913 is 2 with a remainder of 490.
Record the quotient 2 as the next digit in the result. 
Result so far: 222.0
Deduct 1826 from 2316 and we're left with 490.
Grab the next digit (1) from the dividend, add it to 490, then carry on: 4901 / 913

Step 7:
913 can be fit into 4901 5 times, resulting in a remainder of 336.
The number 5 becomes the next digit in our result. 
Result so far: 2225.0
If we subtract 4565 from 4901, we get 336.
Append the next digit (5) from the dividend to 336 and continue with: 3365 / 913

Let's proceed to step 8:
913 goes into 3365 3 times with a remainder of 626.
Write down 3 as next digit of the result. 
Result so far: 22253.0
Subtract 2739 from 3365 to get 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Advancing to step 9:
When dividing 6260 by 913, we get 6 with a remainder of 782.
Use 6 as the next digit of our solution. 
Result so far: 22253.6
If we subtract 5478 from 6260, we get 782.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7820, and continue the process.

Moving on to step 10:
When dividing 7820 by 913, we get 8 with a remainder of 516.
Use 8 as the next digit of our solution. 
Result so far: 22253.68
The remainder is 516 after subtracting 7304 from 7820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

On to step 11:
The number 913 fits into 5160 5 times, leaving a remainder of 595.
The next digit of our result is 5. 
Result so far: 22253.685
The remainder is 595 after subtracting 4565 from 5160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

On to step 12:
913 can be fit into 5950 6 times, resulting in a remainder of 472.
The number 6 becomes the next digit in our result. 
Result so far: 22253.6856
Subtract 5478 from 5950 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.

Going ahead to step 13:
913 can be fit into 4720 5 times, resulting in a remainder of 155.
Record the quotient 5 as the next digit in the result. 
Result so far: 22253.68565
If we subtract 4565 from 4720, we get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Step 14:
913 can be fit into 1550 1 times, resulting in a remainder of 637.
Write down 1 as next digit of the result. 
Result so far: 22253.685651
The remainder is 637 after subtracting 913 from 1550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6370, and continue the process.

Advancing to step 15:
When dividing 6370 by 913, we get 6 with a remainder of 892.
Record the quotient 6 as the next digit in the result. 
Result so far: 22253.6856516
If we take 5478 away from 6370, we end up with 892.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8920, and continue the process.

Advancing to step 16:
If we divide 8920 by 913, we get 9 and a remainder of 703.
The number 9 becomes the next digit in our result. 
Result so far: 22253.68565169
If we take 8217 away from 8920, we end up with 703.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7030, and continue the process.

The quotient of the division is 22253.68565169, and the remainder is 7.03e-07.
