866595 ÷ 59 
The aim is to understand the frequency of 59 in 866595.

Step 1:
8 divided by 59 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 59

Moving on to step 2:
When dividing 86 by 59, we get 1 with a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 59 from 86 leaves us with 27.
Fetch the next digit (6) from the dividend, attach it to 27 and continue: 276 / 59

On to step 3:
59 can be fit into 276 4 times, resulting in a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we subtract 236 from 276, we get 40.
Include the next digit (5) from the dividend after 40, then repeat: 405 / 59

Going ahead to step 4:
The number 59 fits into 405 6 times, leaving a remainder of 51.
Record the quotient 6 as the next digit in the result. 
Result so far: 146.0
Subtracting 354 from 405 leaves us with 51.
Grab the next digit (9) from the dividend, add it to 51, then carry on: 519 / 59

Moving on to step 5:
59 goes into 519 8 times with a remainder of 47.
The number 8 becomes the next digit in our result. 
Result so far: 1468.0
Subtract 472 from 519 to get 47.
Fetch the next digit (5) from the dividend, attach it to 47 and continue: 475 / 59

Advancing to step 6:
If we divide 475 by 59, we get 8 and a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 14688.0
Subtract 472 from 475 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
The number 59 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 14688.0
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
The number 59 fits into 300 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 14688.05
Subtract 295 from 300 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
50 divided by 59 is 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 14688.05
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 10:
59 goes into 500 8 times with a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 14688.0508
If we subtract 472 from 500, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 11:
59 goes into 280 4 times with a remainder of 44.
Use 4 as the next digit of our solution. 
Result so far: 14688.05084
If we subtract 236 from 280, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 12:
When dividing 440 by 59, we get 7 with a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 14688.050847
If we take 413 away from 440, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 13:
When dividing 270 by 59, we get 4 with a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 14688.0508474
Subtracting 236 from 270 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 14:
59 can be fit into 340 5 times, resulting in a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 14688.05084745
The remainder is 45 after subtracting 295 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final outcome is 14688.05084745, with a leftover of 4.5e-08.
