We're dividing 623484 by 86 
We're looking to find how many times 86 goes into 623484.

Going ahead to step 1:
The number 86 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 86

Step 2:
If we divide 62 by 86, we get 0 and a remainder of 62.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 62 after subtracting 0 from 62.
Include the next digit (3) from the dividend after 62, then repeat: 623 / 86

Let's proceed to step 3:
86 can be fit into 623 7 times, resulting in a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 602 from 623 leaves us with 21.
Fetch the next digit (4) from the dividend, attach it to 21 and continue: 214 / 86

Step 4:
When dividing 214 by 86, we get 2 with a remainder of 42.
Use 2 as the next digit of our solution. 
Result so far: 72.0
The remainder is 42 after subtracting 172 from 214.
Bring next digit (8) of the dividend behind the 42 and repeat the process: 428 / 86

Going ahead to step 5:
428 divided by 86 is 4 with a remainder of 84.
The number 4 becomes the next digit in our result. 
Result so far: 724.0
The remainder is 84 after subtracting 344 from 428.
Take the next digit (4) from the dividend and append it to 84, then repeat: 844 / 86

On to step 6:
86 can be fit into 844 9 times, resulting in a remainder of 70.
Record the quotient 9 as the next digit in the result. 
Result so far: 7249.0
If we subtract 774 from 844, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 7:
86 goes into 700 8 times with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 7249.8
Deduct 688 from 700 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
86 goes into 120 1 times with a remainder of 34.
The next digit of our result is 1. 
Result so far: 7249.81
The remainder is 34 after subtracting 86 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 9:
If we divide 340 by 86, we get 3 and a remainder of 82.
The next digit of our result is 3. 
Result so far: 7249.813
Deduct 258 from 340 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 10:
86 can be fit into 820 9 times, resulting in a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 7249.8139
The remainder is 46 after subtracting 774 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 11:
When dividing 460 by 86, we get 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 7249.81395
Deduct 430 from 460 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 12:
The number 86 fits into 300 3 times, leaving a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 7249.813953
If we take 258 away from 300, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 13:
If we divide 420 by 86, we get 4 and a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 7249.8139534
The remainder is 76 after subtracting 344 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 14:
86 goes into 760 8 times with a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 7249.81395348
Deduct 688 from 760 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

After the division, we end up with 7249.81395348 and a remainder of 7.2e-08.
