We look at the division of 303734 by 87 
We're looking to find how many times 87 goes into 303734.

Going ahead to step 1:
87 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 87

Step 2:
87 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Take the next digit (3) from the dividend and append it to 30, then repeat: 303 / 87

Going ahead to step 3:
If we divide 303 by 87, we get 3 and a remainder of 42.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 261 from 303 leaves us with 42.
Bring next digit (7) of the dividend behind the 42 and repeat the process: 427 / 87

Going ahead to step 4:
The number 87 fits into 427 4 times, leaving a remainder of 79.
Write down 4 as next digit of the result. 
Result so far: 34.0
Subtract 348 from 427 to get 79.
Take the next digit (3) from the dividend and append it to 79, then repeat: 793 / 87

Advancing to step 5:
87 can be fit into 793 9 times, resulting in a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 349.0
The remainder is 10 after subtracting 783 from 793.
Grab the next digit (4) from the dividend, add it to 10, then carry on: 104 / 87

Let's proceed to step 6:
If we divide 104 by 87, we get 1 and a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 3491.0
The remainder is 17 after subtracting 87 from 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
When dividing 170 by 87, we get 1 with a remainder of 83.
Record the quotient 1 as the next digit in the result. 
Result so far: 3491.1
If we subtract 87 from 170, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 8:
The number 87 fits into 830 9 times, leaving a remainder of 47.
Record the quotient 9 as the next digit in the result. 
Result so far: 3491.19
Deduct 783 from 830 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 9:
87 can be fit into 470 5 times, resulting in a remainder of 35.
The next digit of our result is 5. 
Result so far: 3491.195
If we take 435 away from 470, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 10:
87 can be fit into 350 4 times, resulting in a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 3491.1954
If we take 348 away from 350, we end up 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 11:
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: 3491.1954
Deduct 0 from 20 and we're left 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.

On to step 12:
If we divide 200 by 87, we get 2 and a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 3491.195402
Subtracting 174 from 200 leaves us 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.

Going ahead to step 13:
The number 87 fits into 260 2 times, leaving a remainder of 86.
The next digit of our result is 2. 
Result so far: 3491.1954022
If we subtract 174 from 260, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

The final outcome is 3491.1954022, with a leftover of 8.6e-07.
