We divide 423303 by 86
We're looking to find how many times 86 goes into 423303.

Let's proceed to step 1:
The number 86 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 86

Going ahead to step 2:
86 can be fit into 42 0 times, resulting in a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Bring next digit (3) of the dividend behind the 42 and repeat the process: 423 / 86

Advancing to step 3:
When dividing 423 by 86, we get 4 with a remainder of 79.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 79 after subtracting 344 from 423.
Bring next digit (3) of the dividend behind the 79 and repeat the process: 793 / 86

Advancing to step 4:
When dividing 793 by 86, we get 9 with a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
If we subtract 774 from 793, we get 19.
Include the next digit (0) from the dividend after 19, then repeat: 190 / 86

Moving on to step 5:
If we divide 190 by 86, we get 2 and a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 492.0
Deduct 172 from 190 and we're left with 18.
Include the next digit (3) from the dividend after 18, then repeat: 183 / 86

On to step 6:
86 goes into 183 2 times with a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 4922.0
The remainder is 11 after subtracting 172 from 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
The number 86 fits into 110 1 times, leaving a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 4922.1
Subtracting 86 from 110 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 8:
86 goes into 240 2 times with a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 4922.12
The remainder is 68 after subtracting 172 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 9:
When dividing 680 by 86, we get 7 with a remainder of 78.
Record the quotient 7 as the next digit in the result. 
Result so far: 4922.127
If we subtract 602 from 680, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 10:
When dividing 780 by 86, we get 9 with a remainder of 6.
The next digit of our result is 9. 
Result so far: 4922.1279
The remainder is 6 after subtracting 774 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 11:
86 can be fit into 60 0 times, resulting in a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 4922.1279
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 12:
If we divide 600 by 86, we get 6 and a remainder of 84.
Record the quotient 6 as the next digit in the result. 
Result so far: 4922.127906
If we take 516 away from 600, we end up 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.

Advancing to step 13:
The number 86 fits into 840 9 times, leaving a remainder of 66.
Write down 9 as next digit of the result. 
Result so far: 4922.1279069
If we take 774 away from 840, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 14:
86 can be fit into 660 7 times, resulting in a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 4922.12790697
If we take 602 away from 660, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The final result is 4922.12790697 with a remainder of 5.8e-08.
