421839 divided by 59 
The aim is to understand the frequency of 59 in 421839.

Step 1:
4 divided by 59 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 59

Going ahead to step 2:
When dividing 42 by 59, we get 0 with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Grab the next digit (1) from the dividend, add it to 42, then carry on: 421 / 59

Moving on to step 3:
If we divide 421 by 59, we get 7 and a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 413 from 421 leaves us with 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 59

Let's proceed to step 4:
The number 59 fits into 88 1 times, leaving a remainder of 29.
The next digit of our result is 1. 
Result so far: 71.0
If we take 59 away from 88, we end up with 29.
Include the next digit (3) from the dividend after 29, then repeat: 293 / 59

On to step 5:
59 can be fit into 293 4 times, resulting in a remainder of 57.
The number 4 becomes the next digit in our result. 
Result so far: 714.0
Subtracting 236 from 293 leaves us with 57.
Fetch the next digit (9) from the dividend, attach it to 57 and continue: 579 / 59

On to step 6:
When dividing 579 by 59, we get 9 with a remainder of 48.
Write down 9 as next digit of the result. 
Result so far: 7149.0
If we subtract 531 from 579, 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.

On to step 7:
The number 59 fits into 480 8 times, leaving a remainder of 8.
The next digit of our result is 8. 
Result so far: 7149.8
Subtract 472 from 480 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
When dividing 80 by 59, we get 1 with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 7149.81
Deduct 59 from 80 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 9:
When dividing 210 by 59, we get 3 with a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 7149.813
Subtract 177 from 210 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 10:
59 can be fit into 330 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 7149.8135
If we take 295 away from 330, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 11:
350 divided by 59 is 5 with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 7149.81355
Subtract 295 from 350 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

In conclusion, the division gives 7149.81355 with a balance of 5.5e-05.
