We look at the division of 31148 by 87 
We want to divide 31148 by 87.

Step 1:
87 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 87

Advancing to step 2:
87 can be fit into 31 0 times, resulting in a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Grab the next digit (1) from the dividend, add it to 31, then carry on: 311 / 87

On to step 3:
If we divide 311 by 87, we get 3 and a remainder of 50.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 261 from 311 leaves us with 50.
Bring next digit (4) of the dividend behind the 50 and repeat the process: 504 / 87

Step 4:
87 goes into 504 5 times with a remainder of 69.
Use 5 as the next digit of our solution. 
Result so far: 35.0
If we take 435 away from 504, we end up with 69.
Grab the next digit (8) from the dividend, add it to 69, then carry on: 698 / 87

Moving on to step 5:
698 divided by 87 is 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 358.0
The remainder is 2 after subtracting 696 from 698.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 6:
If we divide 20 by 87, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 358.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 7:
When dividing 200 by 87, we get 2 with a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 358.02
If we take 174 away from 200, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 8:
260 divided by 87 is 2 with a remainder of 86.
Use 2 as the next digit of our solution. 
Result so far: 358.022
If we take 174 away from 260, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Our division results in 358.022 with a remaining 0.0086.
