64392171 ÷ 59 
The aim is to understand the frequency of 59 in 64392171.

Moving on to step 1:
59 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 59

Moving on to step 2:
59 can be fit into 64 1 times, resulting in a remainder of 5.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 59 from 64 and we're left with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 59

Let's proceed to step 3:
59 can be fit into 53 0 times, resulting in a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 53, we end up with 53.
Append the next digit (9) from the dividend to 53 and continue with: 539 / 59

On to step 4:
The number 59 fits into 539 9 times, leaving a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 109.0
If we take 531 away from 539, we end up with 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 59

Step 5:
59 goes into 82 1 times with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1091.0
Subtract 59 from 82 to get 23.
Include the next digit (1) from the dividend after 23, then repeat: 231 / 59

On to step 6:
When dividing 231 by 59, we get 3 with a remainder of 54.
Write down 3 as next digit of the result. 
Result so far: 10913.0
Subtracting 177 from 231 leaves us with 54.
Take the next digit (7) from the dividend and append it to 54, then repeat: 547 / 59

Going ahead to step 7:
The number 59 fits into 547 9 times, leaving a remainder of 16.
Put 9 as the next digit of the answer. 
Result so far: 109139.0
If we subtract 531 from 547, we get 16.
Take the next digit (1) from the dividend and append it to 16, then repeat: 161 / 59

Moving on to step 8:
59 goes into 161 2 times with a remainder of 43.
Use 2 as the next digit of our solution. 
Result so far: 1091392.0
If we subtract 118 from 161, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 9:
When dividing 430 by 59, we get 7 with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 1091392.7
Deduct 413 from 430 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 10:
59 can be fit into 170 2 times, resulting in a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 1091392.72
Deduct 118 from 170 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 11:
The number 59 fits into 520 8 times, leaving a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 1091392.728
Subtracting 472 from 520 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.

Advancing to step 12:
59 can be fit into 480 8 times, resulting in a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 1091392.7288
Subtracting 472 from 480 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 1091392.7288, with a leftover of 8e-05.
