We look at the division of 12455 by 58 
Let's see how many times 58 fits into 12455.

On to step 1:
When dividing 1 by 58, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 58

Advancing to step 2:
12 divided by 58 is 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 58

Step 3:
If we divide 124 by 58, we get 2 and a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 116 away from 124, we end up with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 58

Step 4:
When dividing 85 by 58, we get 1 with a remainder of 27.
The next digit of our result is 1. 
Result so far: 21.0
Deduct 58 from 85 and we're left with 27.
Append the next digit (5) from the dividend to 27 and continue with: 275 / 58

Advancing to step 5:
When dividing 275 by 58, we get 4 with a remainder of 43.
Use 4 as the next digit of our solution. 
Result so far: 214.0
Subtracting 232 from 275 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.

Going ahead to step 6:
When dividing 430 by 58, we get 7 with a remainder of 24.
The next digit of our result is 7. 
Result so far: 214.7
The remainder is 24 after subtracting 406 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 7:
When dividing 240 by 58, we get 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 214.74
Subtract 232 from 240 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.

On to step 8:
When dividing 80 by 58, we get 1 with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 214.741
If we take 58 away from 80, we end up 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 9:
The number 58 fits into 220 3 times, leaving a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 214.7413
If we take 174 away from 220, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 10:
460 divided by 58 is 7 with a remainder of 54.
Record the quotient 7 as the next digit in the result. 
Result so far: 214.74137
If we subtract 406 from 460, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 11:
When dividing 540 by 58, we get 9 with a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 214.741379
If we take 522 away from 540, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 12:
When dividing 180 by 58, we get 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 214.7413793
Deduct 174 from 180 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 13:
58 goes into 60 1 times with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 214.74137931
Subtract 58 from 60 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 214.74137931 with a remainder of 2e-09.
