138487 divided by 4 
Let's see how many times 4 fits into 138487.

On to step 1:
If we divide 1 by 4, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 4

Advancing to step 2:
When dividing 13 by 4, we get 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 12 from 13 leaves us with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 4

Let's proceed to step 3:
18 divided by 4 is 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 34.0
Subtract 16 from 18 to get 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 4

On to step 4:
If we divide 24 by 4, we get 6 and a remainder of 0.
The next digit of our result is 6. 
Result so far: 346.0
The remainder is 0 after subtracting 24 from 24.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 4

Step 5:
4 can be fit into 8 2 times, resulting in a remainder of 0.
The next digit of our result is 2. 
Result so far: 3462.0
The remainder is 0 after subtracting 8 from 8.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 4

Step 6:
When dividing 7 by 4, we get 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 34621.0
Deduct 4 from 7 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 7:
4 can be fit into 30 7 times, resulting in a remainder of 2.
The next digit of our result is 7. 
Result so far: 34621.7
Deduct 28 from 30 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
The number 4 fits into 20 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 34621.75
Subtract 20 from 20 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
If we divide 0 by 4, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 34621.75
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
0 divided by 4 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 34621.75
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 34621.75 and a remainder of 0.0.
