693643 divided by 86 
Our goal is to divide 693643 by 86.

On to step 1:
When dividing 6 by 86, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 86

Advancing to step 2:
69 divided by 86 is 0 with a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 69 leaves us with 69.
Grab the next digit (3) from the dividend, add it to 69, then carry on: 693 / 86

Step 3:
693 divided by 86 is 8 with a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 688 from 693, we get 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 86

Going ahead to step 4:
86 goes into 56 0 times with a remainder of 56.
Write down 0 as next digit of the result. 
Result so far: 80.0
Subtract 0 from 56 to get 56.
Fetch the next digit (4) from the dividend, attach it to 56 and continue: 564 / 86

Let's proceed to step 5:
86 can be fit into 564 6 times, resulting in a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 806.0
Subtract 516 from 564 to get 48.
Include the next digit (3) from the dividend after 48, then repeat: 483 / 86

Going ahead to step 6:
When dividing 483 by 86, we get 5 with a remainder of 53.
Use 5 as the next digit of our solution. 
Result so far: 8065.0
If we subtract 430 from 483, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 7:
86 can be fit into 530 6 times, resulting in a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 8065.6
Subtracting 516 from 530 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
86 can be fit into 140 1 times, resulting in a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 8065.61
Deduct 86 from 140 and we're left 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.

On to step 9:
86 can be fit into 540 6 times, resulting in a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 8065.616
The remainder is 24 after subtracting 516 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
86 goes into 240 2 times with a remainder of 68.
The next digit of our result is 2. 
Result so far: 8065.6162
If we take 172 away from 240, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 11:
When dividing 680 by 86, we get 7 with a remainder of 78.
Write down 7 as next digit of the result. 
Result so far: 8065.61627
If we take 602 away from 680, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 12:
86 can be fit into 780 9 times, resulting in a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 8065.616279
If we take 774 away from 780, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 13:
86 can be fit into 60 0 times, resulting in a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 8065.616279
Deduct 0 from 60 and we're left 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 14:
86 goes into 600 6 times with a remainder of 84.
Put 6 as the next digit of the answer. 
Result so far: 8065.61627906
Subtracting 516 from 600 leaves us 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.

In conclusion, the division gives 8065.61627906 with a balance of 8.4e-08.
