Let's divide 689457 by 86
Our goal is to divide 689457 by 86.

On to step 1:
86 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 86

Let's proceed to step 2:
68 divided by 86 is 0 with a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Take the next digit (9) from the dividend and append it to 68, then repeat: 689 / 86

Going ahead to step 3:
86 can be fit into 689 8 times, resulting in a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 688 from 689 and we're left with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 86

Advancing to step 4:
86 can be fit into 14 0 times, resulting in a remainder of 14.
The next digit of our result is 0. 
Result so far: 80.0
Subtracting 0 from 14 leaves us with 14.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 86

Let's proceed to step 5:
86 goes into 145 1 times with a remainder of 59.
Write down 1 as next digit of the result. 
Result so far: 801.0
Subtract 86 from 145 to get 59.
Include the next digit (7) from the dividend after 59, then repeat: 597 / 86

Let's proceed to step 6:
If we divide 597 by 86, we get 6 and a remainder of 81.
Put 6 as the next digit of the answer. 
Result so far: 8016.0
Subtract 516 from 597 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 7:
The number 86 fits into 810 9 times, leaving a remainder of 36.
The number 9 becomes the next digit in our result. 
Result so far: 8016.9
Deduct 774 from 810 and we're left 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.

Step 8:
When dividing 360 by 86, we get 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 8016.94
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.

Moving on to step 9:
86 goes into 160 1 times with a remainder of 74.
Write down 1 as next digit of the result. 
Result so far: 8016.941
The remainder is 74 after subtracting 86 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 10:
740 divided by 86 is 8 with a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 8016.9418
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.

Going ahead to step 11:
If we divide 520 by 86, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 8016.94186
If we subtract 516 from 520, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 12:
When dividing 40 by 86, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 8016.94186
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 13:
The number 86 fits into 400 4 times, leaving a remainder of 56.
The next digit of our result is 4. 
Result so far: 8016.9418604
If we subtract 344 from 400, we 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 14:
86 goes into 560 6 times with a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 8016.94186046
The remainder is 44 after subtracting 516 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final result is 8016.94186046 with a remainder of 4.4e-08.
