We look at the division of 86451805 by 291 
Our goal is to divide 86451805 by 291.

Step 1:
291 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 291

Let's proceed to step 2:
291 can be fit into 86 0 times, resulting in a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Fetch the next digit (4) from the dividend, attach it to 86 and continue: 864 / 291

Let's proceed to step 3:
864 divided by 291 is 2 with a remainder of 282.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 582 from 864 and we're left with 282.
Fetch the next digit (5) from the dividend, attach it to 282 and continue: 2825 / 291

Step 4:
291 can be fit into 2825 9 times, resulting in a remainder of 206.
Put 9 as the next digit of the answer. 
Result so far: 29.0
Deduct 2619 from 2825 and we're left with 206.
Include the next digit (1) from the dividend after 206, then repeat: 2061 / 291

Advancing to step 5:
The number 291 fits into 2061 7 times, leaving a remainder of 24.
The next digit of our result is 7. 
Result so far: 297.0
Subtracting 2037 from 2061 leaves us with 24.
Fetch the next digit (8) from the dividend, attach it to 24 and continue: 248 / 291

Let's proceed to step 6:
291 goes into 248 0 times with a remainder of 248.
The next digit of our result is 0. 
Result so far: 2970.0
Deduct 0 from 248 and we're left with 248.
Grab the next digit (0) from the dividend, add it to 248, then carry on: 2480 / 291

Moving on to step 7:
291 goes into 2480 8 times with a remainder of 152.
The number 8 becomes the next digit in our result. 
Result so far: 29708.0
Subtract 2328 from 2480 to get 152.
Fetch the next digit (5) from the dividend, attach it to 152 and continue: 1525 / 291

Going ahead to step 8:
1525 divided by 291 is 5 with a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 297085.0
Deduct 1455 from 1525 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 9:
The number 291 fits into 700 2 times, leaving a remainder of 118.
The number 2 becomes the next digit in our result. 
Result so far: 297085.2
If we subtract 582 from 700, we get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Let's proceed to step 10:
The number 291 fits into 1180 4 times, leaving a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 297085.24
Subtracting 1164 from 1180 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
The number 291 fits into 160 0 times, leaving a remainder of 160.
The next digit of our result is 0. 
Result so far: 297085.24
Subtract 0 from 160 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 12:
291 can be fit into 1600 5 times, resulting in a remainder of 145.
Put 5 as the next digit of the answer. 
Result so far: 297085.2405
If we take 1455 away from 1600, we end up with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Moving on to step 13:
When dividing 1450 by 291, we get 4 with a remainder of 286.
Use 4 as the next digit of our solution. 
Result so far: 297085.24054
Subtract 1164 from 1450 to get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Moving on to step 14:
If we divide 2860 by 291, we get 9 and a remainder of 241.
Write down 9 as next digit of the result. 
Result so far: 297085.240549
The remainder is 241 after subtracting 2619 from 2860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Advancing to step 15:
291 can be fit into 2410 8 times, resulting in a remainder of 82.
Use 8 as the next digit of our solution. 
Result so far: 297085.2405498
Subtracting 2328 from 2410 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 16:
291 goes into 820 2 times with a remainder of 238.
The number 2 becomes the next digit in our result. 
Result so far: 297085.24054982
If we subtract 582 from 820, we get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

The final outcome is 297085.24054982, with a leftover of 2.38e-07.
