Let's divide 305513 by 87
We want to divide 305513 by 87.

Going ahead to step 1:
The number 87 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 87

Let's proceed to step 2:
30 divided by 87 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Grab the next digit (5) from the dividend, add it to 30, then carry on: 305 / 87

Step 3:
87 goes into 305 3 times with a remainder of 44.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 261 from 305, we get 44.
Fetch the next digit (5) from the dividend, attach it to 44 and continue: 445 / 87

Advancing to step 4:
87 goes into 445 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 35.0
Subtract 435 from 445 to get 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 87

On to step 5:
When dividing 101 by 87, we get 1 with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 351.0
The remainder is 14 after subtracting 87 from 101.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 87

Going ahead to step 6:
87 can be fit into 143 1 times, resulting in a remainder of 56.
Write down 1 as next digit of the result. 
Result so far: 3511.0
Deduct 87 from 143 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 7:
560 divided by 87 is 6 with a remainder of 38.
Write down 6 as next digit of the result. 
Result so far: 3511.6
If we subtract 522 from 560, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 8:
When dividing 380 by 87, we get 4 with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 3511.64
Subtract 348 from 380 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
If we divide 320 by 87, we get 3 and a remainder of 59.
Record the quotient 3 as the next digit in the result. 
Result so far: 3511.643
Subtracting 261 from 320 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 10:
590 divided by 87 is 6 with a remainder of 68.
The number 6 becomes the next digit in our result. 
Result so far: 3511.6436
The remainder is 68 after subtracting 522 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 11:
87 can be fit into 680 7 times, resulting in a remainder of 71.
The next digit of our result is 7. 
Result so far: 3511.64367
If we subtract 609 from 680, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 12:
87 can be fit into 710 8 times, resulting in a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 3511.643678
Subtract 696 from 710 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 13:
140 divided by 87 is 1 with a remainder of 53.
Put 1 as the next digit of the answer. 
Result so far: 3511.6436781
Subtracting 87 from 140 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 14:
87 goes into 530 6 times with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 3511.64367816
If we take 522 away from 530, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 3511.64367816, with a leftover of 8e-09.
