We're dividing 315141 by 87 
We're looking to find how many times 87 goes into 315141.

Let's proceed to step 1:
If we divide 3 by 87, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 87

On to step 2:
When dividing 31 by 87, we get 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Append the next digit (5) from the dividend to 31 and continue with: 315 / 87

Let's proceed to step 3:
When dividing 315 by 87, we get 3 with a remainder of 54.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 54 after subtracting 261 from 315.
Grab the next digit (1) from the dividend, add it to 54, then carry on: 541 / 87

Moving on to step 4:
When dividing 541 by 87, we get 6 with a remainder of 19.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
Subtract 522 from 541 to get 19.
Append the next digit (4) from the dividend to 19 and continue with: 194 / 87

Step 5:
The number 87 fits into 194 2 times, leaving a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 362.0
Subtracting 174 from 194 leaves us with 20.
Grab the next digit (1) from the dividend, add it to 20, then carry on: 201 / 87

Going ahead to step 6:
When dividing 201 by 87, we get 2 with a remainder of 27.
The next digit of our result is 2. 
Result so far: 3622.0
Deduct 174 from 201 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 7:
87 goes into 270 3 times with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 3622.3
The remainder is 9 after subtracting 261 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 8:
90 divided by 87 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 3622.31
If we subtract 87 from 90, we get 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 9:
87 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 3622.31
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
When dividing 300 by 87, we get 3 with a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 3622.3103
Deduct 261 from 300 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 11:
87 goes into 390 4 times with a remainder of 42.
Use 4 as the next digit of our solution. 
Result so far: 3622.31034
If we subtract 348 from 390, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 12:
When dividing 420 by 87, we get 4 with a remainder of 72.
The next digit of our result is 4. 
Result so far: 3622.310344
Subtracting 348 from 420 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The quotient of the division is 3622.310344, and the remainder is 7.2e-06.
