We're dividing 423696 by 86 
Our goal is to divide 423696 by 86.

Moving on to step 1:
The number 86 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 86

Advancing to step 2:
The number 86 fits into 42 0 times, leaving a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Bring next digit (3) of the dividend behind the 42 and repeat the process: 423 / 86

On to step 3:
If we divide 423 by 86, we get 4 and a remainder of 79.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 344 from 423, we get 79.
Grab the next digit (6) from the dividend, add it to 79, then carry on: 796 / 86

Let's proceed to step 4:
The number 86 fits into 796 9 times, leaving a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 49.0
If we take 774 away from 796, we end up with 22.
Take the next digit (9) from the dividend and append it to 22, then repeat: 229 / 86

Going ahead to step 5:
86 can be fit into 229 2 times, resulting in a remainder of 57.
Write down 2 as next digit of the result. 
Result so far: 492.0
Deduct 172 from 229 and we're left with 57.
Take the next digit (6) from the dividend and append it to 57, then repeat: 576 / 86

Advancing to step 6:
When dividing 576 by 86, we get 6 with a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 4926.0
Deduct 516 from 576 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.

Going ahead to step 7:
When dividing 600 by 86, we get 6 with a remainder of 84.
Record the quotient 6 as the next digit in the result. 
Result so far: 4926.6
The remainder is 84 after subtracting 516 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 8:
86 can be fit into 840 9 times, resulting in a remainder of 66.
Put 9 as the next digit of the answer. 
Result so far: 4926.69
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 9:
The number 86 fits into 660 7 times, leaving a remainder of 58.
The next digit of our result is 7. 
Result so far: 4926.697
The remainder is 58 after subtracting 602 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 10:
86 goes into 580 6 times with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 4926.6976
Deduct 516 from 580 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 11:
640 divided by 86 is 7 with a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 4926.69767
If we subtract 602 from 640, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 12:
When dividing 380 by 86, we get 4 with a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 4926.697674
The remainder is 36 after subtracting 344 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 13:
86 can be fit into 360 4 times, resulting in a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 4926.6976744
The remainder is 16 after subtracting 344 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 4926.6976744 with a remaining 1.6e-07.
