20433993 ÷ 913 
The aim is to understand the frequency of 913 in 20433993.

Let's proceed to step 1:
If we divide 2 by 913, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 913

On to step 2:
If we divide 20 by 913, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Include the next digit (4) from the dividend after 20, then repeat: 204 / 913

Moving on to step 3:
If we divide 204 by 913, we get 0 and a remainder of 204.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 204, we end up with 204.
Fetch the next digit (3) from the dividend, attach it to 204 and continue: 2043 / 913

Going ahead to step 4:
913 goes into 2043 2 times with a remainder of 217.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 1826 from 2043 to get 217.
Take the next digit (3) from the dividend and append it to 217, then repeat: 2173 / 913

Advancing to step 5:
The number 913 fits into 2173 2 times, leaving a remainder of 347.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Subtract 1826 from 2173 to get 347.
Grab the next digit (9) from the dividend, add it to 347, then carry on: 3479 / 913

Moving on to step 6:
913 goes into 3479 3 times with a remainder of 740.
The next digit of our result is 3. 
Result so far: 223.0
If we subtract 2739 from 3479, we get 740.
Fetch the next digit (9) from the dividend, attach it to 740 and continue: 7409 / 913

Going ahead to step 7:
913 goes into 7409 8 times with a remainder of 105.
Record the quotient 8 as the next digit in the result. 
Result so far: 2238.0
If we subtract 7304 from 7409, we get 105.
Take the next digit (3) from the dividend and append it to 105, then repeat: 1053 / 913

On to step 8:
The number 913 fits into 1053 1 times, leaving a remainder of 140.
Use 1 as the next digit of our solution. 
Result so far: 22381.0
Subtract 913 from 1053 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 9:
The number 913 fits into 1400 1 times, leaving a remainder of 487.
Record the quotient 1 as the next digit in the result. 
Result so far: 22381.1
If we subtract 913 from 1400, we get 487.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4870, and continue the process.

Step 10:
When dividing 4870 by 913, we get 5 with a remainder of 305.
Write down 5 as next digit of the result. 
Result so far: 22381.15
If we take 4565 away from 4870, we end up with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Going ahead to step 11:
The number 913 fits into 3050 3 times, leaving a remainder of 311.
The next digit of our result is 3. 
Result so far: 22381.153
The remainder is 311 after subtracting 2739 from 3050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Let's proceed to step 12:
3110 divided by 913 is 3 with a remainder of 371.
Record the quotient 3 as the next digit in the result. 
Result so far: 22381.1533
The remainder is 371 after subtracting 2739 from 3110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Our division results in 22381.1533 with a remaining 0.00371.
