We look at the division of 645416 by 59 
The aim is to understand the frequency of 59 in 645416.

Advancing to step 1:
59 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 59

Going ahead to step 2:
64 divided by 59 is 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 59 away from 64, we end up with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 59

Step 3:
59 goes into 55 0 times with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 55, we end up with 55.
Take the next digit (4) from the dividend and append it to 55, then repeat: 554 / 59

Advancing to step 4:
If we divide 554 by 59, we get 9 and a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 109.0
The remainder is 23 after subtracting 531 from 554.
Take the next digit (1) from the dividend and append it to 23, then repeat: 231 / 59

Let's proceed to step 5:
59 goes into 231 3 times with a remainder of 54.
The number 3 becomes the next digit in our result. 
Result so far: 1093.0
Subtracting 177 from 231 leaves us with 54.
Fetch the next digit (6) from the dividend, attach it to 54 and continue: 546 / 59

Moving on to step 6:
When dividing 546 by 59, we get 9 with a remainder of 15.
The next digit of our result is 9. 
Result so far: 10939.0
If we take 531 away from 546, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
When dividing 150 by 59, we get 2 with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 10939.2
Subtract 118 from 150 to 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.

On to step 8:
59 can be fit into 320 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 10939.25
Deduct 295 from 320 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 9:
59 can be fit into 250 4 times, resulting in a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 10939.254
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.

Let's proceed to step 10:
When dividing 140 by 59, we get 2 with a remainder of 22.
The next digit of our result is 2. 
Result so far: 10939.2542
The remainder is 22 after subtracting 118 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 11:
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: 10939.25423
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.

Let's proceed to step 12:
59 can be fit into 430 7 times, resulting in a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 10939.254237
The remainder is 17 after subtracting 413 from 430.
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 13:
170 divided by 59 is 2 with a remainder of 52.
The next digit of our result is 2. 
Result so far: 10939.2542372
If we subtract 118 from 170, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 14:
520 divided by 59 is 8 with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 10939.25423728
The remainder is 48 after subtracting 472 from 520.
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 10939.25423728, with a leftover of 4.8e-08.
