91070255 ÷ 300 
We want to divide 91070255 by 300.

On to step 1:
300 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 300

Step 2:
91 divided by 300 is 0 with a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 91 leaves us with 91.
Take the next digit (0) from the dividend and append it to 91, then repeat: 910 / 300

Going ahead to step 3:
300 goes into 910 3 times with a remainder of 10.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 900 from 910 and we're left with 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 300

On to step 4:
107 divided by 300 is 0 with a remainder of 107.
The next digit of our result is 0. 
Result so far: 30.0
Subtract 0 from 107 to get 107.
Append the next digit (0) from the dividend to 107 and continue with: 1070 / 300

Step 5:
When dividing 1070 by 300, we get 3 with a remainder of 170.
Use 3 as the next digit of our solution. 
Result so far: 303.0
If we take 900 away from 1070, we end up with 170.
Append the next digit (2) from the dividend to 170 and continue with: 1702 / 300

On to step 6:
The number 300 fits into 1702 5 times, leaving a remainder of 202.
Use 5 as the next digit of our solution. 
Result so far: 3035.0
If we subtract 1500 from 1702, we get 202.
Fetch the next digit (5) from the dividend, attach it to 202 and continue: 2025 / 300

Going ahead to step 7:
When dividing 2025 by 300, we get 6 with a remainder of 225.
Put 6 as the next digit of the answer. 
Result so far: 30356.0
If we take 1800 away from 2025, we end up with 225.
Append the next digit (5) from the dividend to 225 and continue with: 2255 / 300

Step 8:
2255 divided by 300 is 7 with a remainder of 155.
Use 7 as the next digit of our solution. 
Result so far: 303567.0
Deduct 2100 from 2255 and we're left with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Going ahead to step 9:
The number 300 fits into 1550 5 times, leaving a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 303567.5
If we take 1500 away from 1550, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
300 goes into 500 1 times with a remainder of 200.
Put 1 as the next digit of the answer. 
Result so far: 303567.51
Subtracting 300 from 500 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 11:
300 goes into 2000 6 times with a remainder of 200.
Record the quotient 6 as the next digit in the result. 
Result so far: 303567.516
If we take 1800 away from 2000, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 12:
300 goes into 2000 6 times with a remainder of 200.
Write down 6 as next digit of the result. 
Result so far: 303567.5166
Subtract 1800 from 2000 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.

The final outcome is 303567.5166, with a leftover of 0.002.
