Let's divide 712869 by 86
Our goal is to divide 712869 by 86.

Going ahead to step 1:
86 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 86

Let's proceed to step 2:
When dividing 71 by 86, we get 0 with a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Include the next digit (2) from the dividend after 71, then repeat: 712 / 86

On to step 3:
86 goes into 712 8 times with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 688 from 712 leaves us with 24.
Take the next digit (8) from the dividend and append it to 24, then repeat: 248 / 86

Going ahead to step 4:
The number 86 fits into 248 2 times, leaving a remainder of 76.
The next digit of our result is 2. 
Result so far: 82.0
Subtracting 172 from 248 leaves us with 76.
Take the next digit (6) from the dividend and append it to 76, then repeat: 766 / 86

Advancing to step 5:
When dividing 766 by 86, we get 8 with a remainder of 78.
The number 8 becomes the next digit in our result. 
Result so far: 828.0
If we take 688 away from 766, we end up with 78.
Grab the next digit (9) from the dividend, add it to 78, then carry on: 789 / 86

On to step 6:
86 goes into 789 9 times with a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 8289.0
Deduct 774 from 789 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
86 can be fit into 150 1 times, resulting in a remainder of 64.
The next digit of our result is 1. 
Result so far: 8289.1
If we take 86 away from 150, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 8:
If we divide 640 by 86, we get 7 and a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 8289.17
If we take 602 away from 640, we end up 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.

Moving on to step 9:
86 goes into 380 4 times with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 8289.174
If we subtract 344 from 380, we 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.

On to step 10:
The number 86 fits into 360 4 times, leaving a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 8289.1744
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.

After the division, we end up with 8289.1744 and a remainder of 0.00016.
