We're dividing 21016419 by 593 
The aim is to understand the frequency of 593 in 21016419.

Going ahead to step 1:
If we divide 2 by 593, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 593

Step 2:
When dividing 21 by 593, we get 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Fetch the next digit (0) from the dividend, attach it to 21 and continue: 210 / 593

Step 3:
593 goes into 210 0 times with a remainder of 210.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 210 leaves us with 210.
Bring next digit (1) of the dividend behind the 210 and repeat the process: 2101 / 593

Going ahead to step 4:
When dividing 2101 by 593, we get 3 with a remainder of 322.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 1779 from 2101 leaves us with 322.
Append the next digit (6) from the dividend to 322 and continue with: 3226 / 593

On to step 5:
The number 593 fits into 3226 5 times, leaving a remainder of 261.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
Subtracting 2965 from 3226 leaves us with 261.
Take the next digit (4) from the dividend and append it to 261, then repeat: 2614 / 593

Moving on to step 6:
The number 593 fits into 2614 4 times, leaving a remainder of 242.
The number 4 becomes the next digit in our result. 
Result so far: 354.0
The remainder is 242 after subtracting 2372 from 2614.
Append the next digit (1) from the dividend to 242 and continue with: 2421 / 593

Step 7:
When dividing 2421 by 593, we get 4 with a remainder of 49.
The number 4 becomes the next digit in our result. 
Result so far: 3544.0
If we subtract 2372 from 2421, we get 49.
Bring next digit (9) of the dividend behind the 49 and repeat the process: 499 / 593

Advancing to step 8:
The number 593 fits into 499 0 times, leaving a remainder of 499.
The next digit of our result is 0. 
Result so far: 35440.0
Subtract 0 from 499 to get 499.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

Going ahead to step 9:
4990 divided by 593 is 8 with a remainder of 246.
Use 8 as the next digit of our solution. 
Result so far: 35440.8
Subtracting 4744 from 4990 leaves us with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Advancing to step 10:
2460 divided by 593 is 4 with a remainder of 88.
The next digit of our result is 4. 
Result so far: 35440.84
If we take 2372 away from 2460, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 11:
593 goes into 880 1 times with a remainder of 287.
The next digit of our result is 1. 
Result so far: 35440.841
Subtract 593 from 880 to get 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Let's proceed to step 12:
593 can be fit into 2870 4 times, resulting in a remainder of 498.
The number 4 becomes the next digit in our result. 
Result so far: 35440.8414
Deduct 2372 from 2870 and we're left with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Going ahead to step 13:
593 can be fit into 4980 8 times, resulting in a remainder of 236.
Record the quotient 8 as the next digit in the result. 
Result so far: 35440.84148
Subtracting 4744 from 4980 leaves us with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

On to step 14:
2360 divided by 593 is 3 with a remainder of 581.
Record the quotient 3 as the next digit in the result. 
Result so far: 35440.841483
If we subtract 1779 from 2360, we get 581.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5810, and continue the process.

On to step 15:
593 can be fit into 5810 9 times, resulting in a remainder of 473.
Write down 9 as next digit of the result. 
Result so far: 35440.8414839
The remainder is 473 after subtracting 5337 from 5810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Moving on to step 16:
When dividing 4730 by 593, we get 7 with a remainder of 579.
The next digit of our result is 7. 
Result so far: 35440.84148397
Subtracting 4151 from 4730 leaves us with 579.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5790, and continue the process.

After the division, we end up with 35440.84148397 and a remainder of 5.79e-07.
