We look at the division of 660381 by 59 
The aim is to understand the frequency of 59 in 660381.

Step 1:
59 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 59

Let's proceed to step 2:
The number 59 fits into 66 1 times, leaving a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 59 from 66 leaves us with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 59

Going ahead to step 3:
59 can be fit into 70 1 times, resulting in a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 59 from 70 to get 11.
Take the next digit (3) from the dividend and append it to 11, then repeat: 113 / 59

Let's proceed to step 4:
When dividing 113 by 59, we get 1 with a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 111.0
Subtracting 59 from 113 leaves us with 54.
Take the next digit (8) from the dividend and append it to 54, then repeat: 548 / 59

Let's proceed to step 5:
If we divide 548 by 59, we get 9 and a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 1119.0
Subtract 531 from 548 to get 17.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 59

On to step 6:
If we divide 171 by 59, we get 2 and a remainder of 53.
Use 2 as the next digit of our solution. 
Result so far: 11192.0
If we take 118 away from 171, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 7:
59 goes into 530 8 times with a remainder of 58.
The next digit of our result is 8. 
Result so far: 11192.8
Subtracting 472 from 530 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 8:
When dividing 580 by 59, we get 9 with a remainder of 49.
Use 9 as the next digit of our solution. 
Result so far: 11192.89
Subtracting 531 from 580 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 9:
If we divide 490 by 59, we get 8 and a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 11192.898
If we subtract 472 from 490, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 10:
59 can be fit into 180 3 times, resulting in a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 11192.8983
Deduct 177 from 180 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 11:
59 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 11192.8983
Subtract 0 from 30 to 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.

Going ahead to step 12:
59 goes into 300 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 11192.898305
If we subtract 295 from 300, we 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.

Going ahead to step 13:
The number 59 fits into 50 0 times, leaving a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 11192.898305
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 14:
The number 59 fits into 500 8 times, leaving a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 11192.89830508
The remainder is 28 after subtracting 472 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Our division results in 11192.89830508 with a remaining 2.8e-08.
