423096 ÷ 86 
We want to divide 423096 by 86.

Moving on to step 1:
The number 86 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 86

Advancing to step 2:
86 can be fit into 42 0 times, resulting in a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Bring next digit (3) of the dividend behind the 42 and repeat the process: 423 / 86

Moving on to step 3:
If we divide 423 by 86, we get 4 and a remainder of 79.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 344 from 423 and we're left with 79.
Take the next digit (0) from the dividend and append it to 79, then repeat: 790 / 86

Moving on to step 4:
When dividing 790 by 86, we get 9 with a remainder of 16.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
If we take 774 away from 790, we end up with 16.
Append the next digit (9) from the dividend to 16 and continue with: 169 / 86

Moving on to step 5:
When dividing 169 by 86, we get 1 with a remainder of 83.
Use 1 as the next digit of our solution. 
Result so far: 491.0
If we take 86 away from 169, we end up with 83.
Bring next digit (6) of the dividend behind the 83 and repeat the process: 836 / 86

Step 6:
When dividing 836 by 86, we get 9 with a remainder of 62.
Use 9 as the next digit of our solution. 
Result so far: 4919.0
Subtract 774 from 836 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 7:
86 goes into 620 7 times with a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 4919.7
If we take 602 away from 620, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 8:
If we divide 180 by 86, we get 2 and a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 4919.72
If we subtract 172 from 180, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
80 divided by 86 is 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 4919.72
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 10:
If we divide 800 by 86, we get 9 and a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 4919.7209
Subtract 774 from 800 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 11:
260 divided by 86 is 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 4919.72093
If we take 258 away from 260, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 12:
86 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 4919.72093
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 13:
The number 86 fits into 200 2 times, leaving a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 4919.7209302
If we take 172 away from 200, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 14:
280 divided by 86 is 3 with a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 4919.72093023
Subtract 258 from 280 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Our division results in 4919.72093023 with a remaining 2.2e-08.
