12858069 divided by 58 
We want to divide 12858069 by 58.

Going ahead to step 1:
The number 58 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 58

On to step 2:
If we divide 12 by 58, we get 0 and a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 58

On to step 3:
58 goes into 128 2 times with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 116 away from 128, we end up with 12.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 58

Let's proceed to step 4:
125 divided by 58 is 2 with a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 22.0
Subtracting 116 from 125 leaves us with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 58

Step 5:
If we divide 98 by 58, we get 1 and a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 221.0
The remainder is 40 after subtracting 58 from 98.
Take the next digit (0) from the dividend and append it to 40, then repeat: 400 / 58

Step 6:
The number 58 fits into 400 6 times, leaving a remainder of 52.
The next digit of our result is 6. 
Result so far: 2216.0
Subtract 348 from 400 to get 52.
Grab the next digit (6) from the dividend, add it to 52, then carry on: 526 / 58

On to step 7:
58 goes into 526 9 times with a remainder of 4.
The next digit of our result is 9. 
Result so far: 22169.0
Subtract 522 from 526 to get 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 58

Step 8:
58 can be fit into 49 0 times, resulting in a remainder of 49.
Put 0 as the next digit of the answer. 
Result so far: 221690.0
The remainder is 49 after subtracting 0 from 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:
490 divided by 58 is 8 with a remainder of 26.
The number 8 becomes the next digit in our result. 
Result so far: 221690.8
If we subtract 464 from 490, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 10:
When dividing 260 by 58, we get 4 with a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 221690.84
Deduct 232 from 260 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 11:
If we divide 280 by 58, we get 4 and a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 221690.844
The remainder is 48 after subtracting 232 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 221690.844 and a remainder of 0.0048.
