We're dividing 12300845 by 291 
Let's see how many times 291 fits into 12300845.

Step 1:
291 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 291

Going ahead to step 2:
If we divide 12 by 291, we get 0 and a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 291

Going ahead to step 3:
When dividing 123 by 291, we get 0 with a remainder of 123.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 123 after subtracting 0 from 123.
Take the next digit (0) from the dividend and append it to 123, then repeat: 1230 / 291

Let's proceed to step 4:
291 goes into 1230 4 times with a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 1164 from 1230 to get 66.
Append the next digit (0) from the dividend to 66 and continue with: 660 / 291

Moving on to step 5:
When dividing 660 by 291, we get 2 with a remainder of 78.
Use 2 as the next digit of our solution. 
Result so far: 42.0
If we take 582 away from 660, we end up with 78.
Bring next digit (8) of the dividend behind the 78 and repeat the process: 788 / 291

Going ahead to step 6:
291 goes into 788 2 times with a remainder of 206.
Record the quotient 2 as the next digit in the result. 
Result so far: 422.0
If we subtract 582 from 788, we get 206.
Append the next digit (4) from the dividend to 206 and continue with: 2064 / 291

Advancing to step 7:
291 goes into 2064 7 times with a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 4227.0
Subtracting 2037 from 2064 leaves us with 27.
Bring next digit (5) of the dividend behind the 27 and repeat the process: 275 / 291

Let's proceed to step 8:
291 can be fit into 275 0 times, resulting in a remainder of 275.
Use 0 as the next digit of our solution. 
Result so far: 42270.0
If we take 0 away from 275, we end up with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Let's proceed to step 9:
291 can be fit into 2750 9 times, resulting in a remainder of 131.
Use 9 as the next digit of our solution. 
Result so far: 42270.9
Deduct 2619 from 2750 and we're left with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Advancing to step 10:
The number 291 fits into 1310 4 times, leaving a remainder of 146.
The number 4 becomes the next digit in our result. 
Result so far: 42270.94
If we subtract 1164 from 1310, we get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Advancing to step 11:
291 goes into 1460 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 42270.945
Deduct 1455 from 1460 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 12:
291 can be fit into 50 0 times, resulting in a remainder of 50.
The next digit of our result is 0. 
Result so far: 42270.945
If we take 0 away from 50, 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 13:
500 divided by 291 is 1 with a remainder of 209.
The number 1 becomes the next digit in our result. 
Result so far: 42270.94501
Deduct 291 from 500 and we're left with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Let's proceed to step 14:
291 goes into 2090 7 times with a remainder of 53.
Put 7 as the next digit of the answer. 
Result so far: 42270.945017
Subtract 2037 from 2090 to get 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 15:
If we divide 530 by 291, we get 1 and a remainder of 239.
Record the quotient 1 as the next digit in the result. 
Result so far: 42270.9450171
Deduct 291 from 530 and we're left with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Moving on to step 16:
The number 291 fits into 2390 8 times, leaving a remainder of 62.
Use 8 as the next digit of our solution. 
Result so far: 42270.94501718
If we take 2328 away from 2390, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The quotient of the division is 42270.94501718, and the remainder is 6.2e-08.
