We divide 86391 by 59
The aim is to understand the frequency of 59 in 86391.

Let's proceed to step 1:
When dividing 8 by 59, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 59

Step 2:
59 can be fit into 86 1 times, resulting in a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 27 after subtracting 59 from 86.
Append the next digit (3) from the dividend to 27 and continue with: 273 / 59

Going ahead to step 3:
59 can be fit into 273 4 times, resulting in a remainder of 37.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtract 236 from 273 to get 37.
Bring next digit (9) of the dividend behind the 37 and repeat the process: 379 / 59

Advancing to step 4:
379 divided by 59 is 6 with a remainder of 25.
Use 6 as the next digit of our solution. 
Result so far: 146.0
Subtracting 354 from 379 leaves us with 25.
Grab the next digit (1) from the dividend, add it to 25, then carry on: 251 / 59

Going ahead to step 5:
When dividing 251 by 59, we get 4 with a remainder of 15.
Record the quotient 4 as the next digit in the result. 
Result so far: 1464.0
Subtract 236 from 251 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 6:
The number 59 fits into 150 2 times, leaving a remainder of 32.
The next digit of our result is 2. 
Result so far: 1464.2
If we subtract 118 from 150, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 7:
The number 59 fits into 320 5 times, leaving a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 1464.25
Subtract 295 from 320 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 8:
The number 59 fits into 250 4 times, leaving a remainder of 14.
The next digit of our result is 4. 
Result so far: 1464.254
Deduct 236 from 250 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
59 goes into 140 2 times with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 1464.2542
Subtracting 118 from 140 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 10:
59 can be fit into 220 3 times, resulting in a remainder of 43.
The number 3 becomes the next digit in our result. 
Result so far: 1464.25423
Subtracting 177 from 220 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 11:
59 can be fit into 430 7 times, resulting in a remainder of 17.
The next digit of our result is 7. 
Result so far: 1464.254237
If we subtract 413 from 430, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 12:
59 goes into 170 2 times with a remainder of 52.
Record the quotient 2 as the next digit in the result. 
Result so far: 1464.2542372
The remainder is 52 after subtracting 118 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 13:
59 can be fit into 520 8 times, resulting in a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 1464.25423728
If we subtract 472 from 520, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 1464.25423728, with a leftover of 4.8e-08.
