Let's divide 136858 by 31
Let's see how many times 31 fits into 136858.

Step 1:
31 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 31

Advancing to step 2:
If we divide 13 by 31, we get 0 and a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Append the next digit (6) from the dividend to 13 and continue with: 136 / 31

Moving on to step 3:
31 goes into 136 4 times with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 12 after subtracting 124 from 136.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 31

Let's proceed to step 4:
31 can be fit into 128 4 times, resulting in a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
Deduct 124 from 128 and we're left with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 31

Moving on to step 5:
45 divided by 31 is 1 with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 441.0
The remainder is 14 after subtracting 31 from 45.
Grab the next digit (8) from the dividend, add it to 14, then carry on: 148 / 31

Moving on to step 6:
If we divide 148 by 31, we get 4 and a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 4414.0
If we subtract 124 from 148, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 7:
The number 31 fits into 240 7 times, leaving a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 4414.7
Deduct 217 from 240 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 8:
The number 31 fits into 230 7 times, leaving a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 4414.77
If we take 217 away from 230, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The quotient of the division is 4414.77, and the remainder is 0.013.
