86385479 divided by 291 
We want to figure out the number of times 86385479 can be divided by 291.

On to step 1:
291 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 291

Let's proceed to step 2:
291 goes into 86 0 times with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Include the next digit (3) from the dividend after 86, then repeat: 863 / 291

Advancing to step 3:
291 goes into 863 2 times with a remainder of 281.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 582 from 863 and we're left with 281.
Fetch the next digit (8) from the dividend, attach it to 281 and continue: 2818 / 291

Let's proceed to step 4:
291 goes into 2818 9 times with a remainder of 199.
Write down 9 as next digit of the result. 
Result so far: 29.0
Subtract 2619 from 2818 to get 199.
Take the next digit (5) from the dividend and append it to 199, then repeat: 1995 / 291

On to step 5:
The number 291 fits into 1995 6 times, leaving a remainder of 249.
Put 6 as the next digit of the answer. 
Result so far: 296.0
Subtract 1746 from 1995 to get 249.
Append the next digit (4) from the dividend to 249 and continue with: 2494 / 291

Going ahead to step 6:
The number 291 fits into 2494 8 times, leaving a remainder of 166.
Use 8 as the next digit of our solution. 
Result so far: 2968.0
Subtract 2328 from 2494 to get 166.
Append the next digit (7) from the dividend to 166 and continue with: 1667 / 291

Advancing to step 7:
1667 divided by 291 is 5 with a remainder of 212.
The number 5 becomes the next digit in our result. 
Result so far: 29685.0
Subtracting 1455 from 1667 leaves us with 212.
Fetch the next digit (9) from the dividend, attach it to 212 and continue: 2129 / 291

Going ahead to step 8:
2129 divided by 291 is 7 with a remainder of 92.
Put 7 as the next digit of the answer. 
Result so far: 296857.0
Subtract 2037 from 2129 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 9:
291 can be fit into 920 3 times, resulting in a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 296857.3
Subtract 873 from 920 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 10:
If we divide 470 by 291, we get 1 and a remainder of 179.
The next digit of our result is 1. 
Result so far: 296857.31
Subtracting 291 from 470 leaves us with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Let's proceed to step 11:
If we divide 1790 by 291, we get 6 and a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 296857.316
If we take 1746 away from 1790, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 12:
291 goes into 440 1 times with a remainder of 149.
Put 1 as the next digit of the answer. 
Result so far: 296857.3161
Subtracting 291 from 440 leaves us with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Advancing to step 13:
If we divide 1490 by 291, we get 5 and a remainder of 35.
The next digit of our result is 5. 
Result so far: 296857.31615
If we subtract 1455 from 1490, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 14:
291 goes into 350 1 times with a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 296857.316151
Subtract 291 from 350 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 15:
291 goes into 590 2 times with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 296857.3161512
If we take 582 away from 590, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 16:
291 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 296857.3161512
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final outcome is 296857.3161512, with a leftover of 8e-08.
