Let's divide 87720563 by 306
We want to divide 87720563 by 306.

Step 1:
If we divide 8 by 306, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 306

Going ahead to step 2:
306 goes into 87 0 times with a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Fetch the next digit (7) from the dividend, attach it to 87 and continue: 877 / 306

On to step 3:
When dividing 877 by 306, we get 2 with a remainder of 265.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 265 after subtracting 612 from 877.
Take the next digit (2) from the dividend and append it to 265, then repeat: 2652 / 306

Step 4:
306 can be fit into 2652 8 times, resulting in a remainder of 204.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
If we subtract 2448 from 2652, we get 204.
Bring next digit (0) of the dividend behind the 204 and repeat the process: 2040 / 306

Let's proceed to step 5:
The number 306 fits into 2040 6 times, leaving a remainder of 204.
The next digit of our result is 6. 
Result so far: 286.0
If we subtract 1836 from 2040, we get 204.
Take the next digit (5) from the dividend and append it to 204, then repeat: 2045 / 306

Let's proceed to step 6:
If we divide 2045 by 306, we get 6 and a remainder of 209.
Write down 6 as next digit of the result. 
Result so far: 2866.0
Deduct 1836 from 2045 and we're left with 209.
Take the next digit (6) from the dividend and append it to 209, then repeat: 2096 / 306

Advancing to step 7:
When dividing 2096 by 306, we get 6 with a remainder of 260.
Use 6 as the next digit of our solution. 
Result so far: 28666.0
Deduct 1836 from 2096 and we're left with 260.
Include the next digit (3) from the dividend after 260, then repeat: 2603 / 306

On to step 8:
306 can be fit into 2603 8 times, resulting in a remainder of 155.
Write down 8 as next digit of the result. 
Result so far: 286668.0
The remainder is 155 after subtracting 2448 from 2603.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Let's proceed to step 9:
When dividing 1550 by 306, we get 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 286668.5
Subtracting 1530 from 1550 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.

On to step 10:
306 goes into 200 0 times with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 286668.5
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 11:
When dividing 2000 by 306, we get 6 with a remainder of 164.
Use 6 as the next digit of our solution. 
Result so far: 286668.506
If we take 1836 away from 2000, we end up with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Advancing to step 12:
The number 306 fits into 1640 5 times, leaving a remainder of 110.
Use 5 as the next digit of our solution. 
Result so far: 286668.5065
Subtract 1530 from 1640 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 13:
306 can be fit into 1100 3 times, resulting in a remainder of 182.
Put 3 as the next digit of the answer. 
Result so far: 286668.50653
If we take 918 away from 1100, we end up with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Moving on to step 14:
When dividing 1820 by 306, we get 5 with a remainder of 290.
Write down 5 as next digit of the result. 
Result so far: 286668.506535
Deduct 1530 from 1820 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 15:
306 can be fit into 2900 9 times, resulting in a remainder of 146.
Record the quotient 9 as the next digit in the result. 
Result so far: 286668.5065359
If we take 2754 away from 2900, we end up with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Step 16:
When dividing 1460 by 306, we get 4 with a remainder of 236.
Record the quotient 4 as the next digit in the result. 
Result so far: 286668.50653594
If we subtract 1224 from 1460, we get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

The final outcome is 286668.50653594, with a leftover of 2.36e-07.
