84136215 divided by 300 
Our goal is to divide 84136215 by 300.

Step 1:
If we divide 8 by 300, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 300

On to step 2:
When dividing 84 by 300, we get 0 with a remainder of 84.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 84 leaves us with 84.
Bring next digit (1) of the dividend behind the 84 and repeat the process: 841 / 300

Advancing to step 3:
The number 300 fits into 841 2 times, leaving a remainder of 241.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 241 after subtracting 600 from 841.
Grab the next digit (3) from the dividend, add it to 241, then carry on: 2413 / 300

Let's proceed to step 4:
300 can be fit into 2413 8 times, resulting in a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Subtracting 2400 from 2413 leaves us with 13.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 300

On to step 5:
300 can be fit into 136 0 times, resulting in a remainder of 136.
Record the quotient 0 as the next digit in the result. 
Result so far: 280.0
Deduct 0 from 136 and we're left with 136.
Append the next digit (2) from the dividend to 136 and continue with: 1362 / 300

Step 6:
1362 divided by 300 is 4 with a remainder of 162.
Use 4 as the next digit of our solution. 
Result so far: 2804.0
Subtract 1200 from 1362 to get 162.
Append the next digit (1) from the dividend to 162 and continue with: 1621 / 300

Let's proceed to step 7:
When dividing 1621 by 300, we get 5 with a remainder of 121.
Put 5 as the next digit of the answer. 
Result so far: 28045.0
If we take 1500 away from 1621, we end up with 121.
Fetch the next digit (5) from the dividend, attach it to 121 and continue: 1215 / 300

Advancing to step 8:
If we divide 1215 by 300, we get 4 and a remainder of 15.
Use 4 as the next digit of our solution. 
Result so far: 280454.0
Deduct 1200 from 1215 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 9:
150 divided by 300 is 0 with a remainder of 150.
Record the quotient 0 as the next digit in the result. 
Result so far: 280454.0
If we take 0 away from 150, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 10:
When dividing 1500 by 300, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 280454.05
Subtract 1500 from 1500 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
300 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 280454.05
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
0 divided by 300 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 280454.05
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 280454.05 and a remainder of 0.0.
