We look at the division of 57981680 by 593 
The aim is to understand the frequency of 593 in 57981680.

On to step 1:
The number 593 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 593

Let's proceed to step 2:
When dividing 57 by 593, we get 0 with a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 57 to get 57.
Take the next digit (9) from the dividend and append it to 57, then repeat: 579 / 593

Let's proceed to step 3:
579 divided by 593 is 0 with a remainder of 579.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 579 and we're left with 579.
Include the next digit (8) from the dividend after 579, then repeat: 5798 / 593

Step 4:
593 goes into 5798 9 times with a remainder of 461.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 5337 from 5798, we get 461.
Take the next digit (1) from the dividend and append it to 461, then repeat: 4611 / 593

Step 5:
The number 593 fits into 4611 7 times, leaving a remainder of 460.
Record the quotient 7 as the next digit in the result. 
Result so far: 97.0
Deduct 4151 from 4611 and we're left with 460.
Bring next digit (6) of the dividend behind the 460 and repeat the process: 4606 / 593

Going ahead to step 6:
593 goes into 4606 7 times with a remainder of 455.
Write down 7 as next digit of the result. 
Result so far: 977.0
If we take 4151 away from 4606, we end up with 455.
Include the next digit (8) from the dividend after 455, then repeat: 4558 / 593

Going ahead to step 7:
When dividing 4558 by 593, we get 7 with a remainder of 407.
Use 7 as the next digit of our solution. 
Result so far: 9777.0
If we take 4151 away from 4558, we end up with 407.
Append the next digit (0) from the dividend to 407 and continue with: 4070 / 593

Moving on to step 8:
If we divide 4070 by 593, we get 6 and a remainder of 512.
Record the quotient 6 as the next digit in the result. 
Result so far: 97776.0
The remainder is 512 after subtracting 3558 from 4070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Let's proceed to step 9:
5120 divided by 593 is 8 with a remainder of 376.
Use 8 as the next digit of our solution. 
Result so far: 97776.8
Subtract 4744 from 5120 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Step 10:
The number 593 fits into 3760 6 times, leaving a remainder of 202.
Use 6 as the next digit of our solution. 
Result so far: 97776.86
Subtracting 3558 from 3760 leaves us with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Let's proceed to step 11:
2020 divided by 593 is 3 with a remainder of 241.
The next digit of our result is 3. 
Result so far: 97776.863
Subtract 1779 from 2020 to get 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Step 12:
The number 593 fits into 2410 4 times, leaving a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 97776.8634
If we take 2372 away from 2410, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 13:
When dividing 380 by 593, we get 0 with a remainder of 380.
The number 0 becomes the next digit in our result. 
Result so far: 97776.8634
If we subtract 0 from 380, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 14:
When dividing 3800 by 593, we get 6 with a remainder of 242.
Record the quotient 6 as the next digit in the result. 
Result so far: 97776.863406
If we subtract 3558 from 3800, we get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Advancing to step 15:
2420 divided by 593 is 4 with a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 97776.8634064
Subtracting 2372 from 2420 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 16:
593 goes into 480 0 times with a remainder of 480.
Write down 0 as next digit of the result. 
Result so far: 97776.8634064
If we take 0 away from 480, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

In conclusion, the division gives 97776.8634064 with a balance of 4.8e-07.
