360991 divided by 86 
We want to figure out the number of times 360991 can be divided by 86.

Step 1:
When dividing 3 by 86, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 86

Advancing to step 2:
86 can be fit into 36 0 times, resulting in a remainder of 36.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 36, we end up with 36.
Append the next digit (0) from the dividend to 36 and continue with: 360 / 86

On to step 3:
360 divided by 86 is 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 4.0
If we take 344 away from 360, we end up with 16.
Fetch the next digit (9) from the dividend, attach it to 16 and continue: 169 / 86

Let's proceed to step 4:
When dividing 169 by 86, we get 1 with a remainder of 83.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
If we take 86 away from 169, we end up with 83.
Bring next digit (9) of the dividend behind the 83 and repeat the process: 839 / 86

Step 5:
If we divide 839 by 86, we get 9 and a remainder of 65.
Record the quotient 9 as the next digit in the result. 
Result so far: 419.0
If we subtract 774 from 839, we get 65.
Bring next digit (1) of the dividend behind the 65 and repeat the process: 651 / 86

Going ahead to step 6:
If we divide 651 by 86, we get 7 and a remainder of 49.
Use 7 as the next digit of our solution. 
Result so far: 4197.0
If we take 602 away from 651, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 7:
When dividing 490 by 86, we get 5 with a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 4197.5
If we take 430 away from 490, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 8:
86 goes into 600 6 times with a remainder of 84.
Record the quotient 6 as the next digit in the result. 
Result so far: 4197.56
Deduct 516 from 600 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 9:
840 divided by 86 is 9 with a remainder of 66.
The number 9 becomes the next digit in our result. 
Result so far: 4197.569
If we subtract 774 from 840, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 10:
86 goes into 660 7 times with a remainder of 58.
Put 7 as the next digit of the answer. 
Result so far: 4197.5697
Subtract 602 from 660 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 11:
580 divided by 86 is 6 with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 4197.56976
The remainder is 64 after subtracting 516 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 12:
If we divide 640 by 86, we get 7 and a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 4197.569767
Deduct 602 from 640 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 13:
When dividing 380 by 86, we get 4 with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 4197.5697674
If we take 344 away from 380, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 14:
86 can be fit into 360 4 times, resulting in a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 4197.56976744
If we subtract 344 from 360, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 4197.56976744 with a balance of 1.6e-08.
