20371964 divided by 583 
The aim is to understand the frequency of 583 in 20371964.

Moving on to step 1:
583 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 583

Going ahead to step 2:
583 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 583

Moving on to step 3:
583 goes into 203 0 times with a remainder of 203.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 203 and we're left with 203.
Take the next digit (7) from the dividend and append it to 203, then repeat: 2037 / 583

Going ahead to step 4:
When dividing 2037 by 583, we get 3 with a remainder of 288.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 1749 from 2037 to get 288.
Include the next digit (1) from the dividend after 288, then repeat: 2881 / 583

On to step 5:
583 can be fit into 2881 4 times, resulting in a remainder of 549.
Write down 4 as next digit of the result. 
Result so far: 34.0
Deduct 2332 from 2881 and we're left with 549.
Include the next digit (9) from the dividend after 549, then repeat: 5499 / 583

Advancing to step 6:
The number 583 fits into 5499 9 times, leaving a remainder of 252.
The next digit of our result is 9. 
Result so far: 349.0
Deduct 5247 from 5499 and we're left with 252.
Fetch the next digit (6) from the dividend, attach it to 252 and continue: 2526 / 583

Let's proceed to step 7:
583 goes into 2526 4 times with a remainder of 194.
Write down 4 as next digit of the result. 
Result so far: 3494.0
If we subtract 2332 from 2526, we get 194.
Bring next digit (4) of the dividend behind the 194 and repeat the process: 1944 / 583

Moving on to step 8:
583 goes into 1944 3 times with a remainder of 195.
Write down 3 as next digit of the result. 
Result so far: 34943.0
Deduct 1749 from 1944 and we're left with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

On to step 9:
When dividing 1950 by 583, we get 3 with a remainder of 201.
Use 3 as the next digit of our solution. 
Result so far: 34943.3
Subtract 1749 from 1950 to get 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Step 10:
If we divide 2010 by 583, we get 3 and a remainder of 261.
Record the quotient 3 as the next digit in the result. 
Result so far: 34943.33
Subtracting 1749 from 2010 leaves us with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

After the division, we end up with 34943.33 and a remainder of 0.261.
