651309 divided by 86 
Our goal is to divide 651309 by 86.

Going ahead to step 1:
If we divide 6 by 86, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 86

Going ahead to step 2:
If we divide 65 by 86, we get 0 and a remainder of 65.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 65 and we're left with 65.
Grab the next digit (1) from the dividend, add it to 65, then carry on: 651 / 86

Advancing to step 3:
651 divided by 86 is 7 with a remainder of 49.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 602 from 651 leaves us with 49.
Bring next digit (3) of the dividend behind the 49 and repeat the process: 493 / 86

Going ahead to step 4:
When dividing 493 by 86, we get 5 with a remainder of 63.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
If we subtract 430 from 493, we get 63.
Append the next digit (0) from the dividend to 63 and continue with: 630 / 86

On to step 5:
If we divide 630 by 86, we get 7 and a remainder of 28.
Put 7 as the next digit of the answer. 
Result so far: 757.0
Subtracting 602 from 630 leaves us with 28.
Fetch the next digit (9) from the dividend, attach it to 28 and continue: 289 / 86

Let's proceed to step 6:
If we divide 289 by 86, we get 3 and a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 7573.0
If we subtract 258 from 289, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 7:
When dividing 310 by 86, we get 3 with a remainder of 52.
The next digit of our result is 3. 
Result so far: 7573.3
Deduct 258 from 310 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 8:
86 goes into 520 6 times with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 7573.36
If we take 516 away from 520, we end up 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.

Going ahead to step 9:
86 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 7573.36
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
86 goes into 400 4 times with a remainder of 56.
The next digit of our result is 4. 
Result so far: 7573.3604
Subtracting 344 from 400 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 11:
86 goes into 560 6 times with a remainder of 44.
The next digit of our result is 6. 
Result so far: 7573.36046
Subtracting 516 from 560 leaves us 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.

Let's proceed to step 12:
86 goes into 440 5 times with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 7573.360465
Subtracting 430 from 440 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
100 divided by 86 is 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 7573.3604651
Subtract 86 from 100 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 14:
The number 86 fits into 140 1 times, leaving a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 7573.36046511
Subtracting 86 from 140 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final outcome is 7573.36046511, with a leftover of 5.4e-08.
