75458 divided by 86 
We want to divide 75458 by 86.

Going ahead to step 1:
7 divided by 86 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 86

Going ahead to step 2:
86 goes into 75 0 times with a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 75 leaves us with 75.
Include the next digit (4) from the dividend after 75, then repeat: 754 / 86

On to step 3:
86 goes into 754 8 times with a remainder of 66.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 688 from 754 to get 66.
Include the next digit (5) from the dividend after 66, then repeat: 665 / 86

Advancing to step 4:
86 can be fit into 665 7 times, resulting in a remainder of 63.
Put 7 as the next digit of the answer. 
Result so far: 87.0
If we take 602 away from 665, we end up with 63.
Bring next digit (8) of the dividend behind the 63 and repeat the process: 638 / 86

On to step 5:
If we divide 638 by 86, we get 7 and a remainder of 36.
The number 7 becomes the next digit in our result. 
Result so far: 877.0
Subtract 602 from 638 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 6:
If we divide 360 by 86, we get 4 and a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 877.4
The remainder is 16 after subtracting 344 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 7:
When dividing 160 by 86, we get 1 with a remainder of 74.
Use 1 as the next digit of our solution. 
Result so far: 877.41
If we subtract 86 from 160, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 8:
The number 86 fits into 740 8 times, leaving a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 877.418
Subtract 688 from 740 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 9:
The number 86 fits into 520 6 times, leaving a remainder of 4.
The next digit of our result is 6. 
Result so far: 877.4186
Deduct 516 from 520 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
The number 86 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 877.4186
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
400 divided by 86 is 4 with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 877.418604
Subtract 344 from 400 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 12:
86 can be fit into 560 6 times, resulting in a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 877.4186046
If we subtract 516 from 560, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 13:
86 can be fit into 440 5 times, resulting in a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 877.41860465
If we subtract 430 from 440, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 877.41860465 with a remainder of 1e-08.
