We're dividing 396667 by 86 
We want to figure out the number of times 396667 can be divided by 86.

Step 1:
86 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 86

Going ahead to step 2:
The number 86 fits into 39 0 times, leaving a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Grab the next digit (6) from the dividend, add it to 39, then carry on: 396 / 86

On to step 3:
If we divide 396 by 86, we get 4 and a remainder of 52.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 344 from 396 to get 52.
Fetch the next digit (6) from the dividend, attach it to 52 and continue: 526 / 86

On to step 4:
If we divide 526 by 86, we get 6 and a remainder of 10.
The next digit of our result is 6. 
Result so far: 46.0
If we take 516 away from 526, we end up with 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 86

Advancing to step 5:
If we divide 106 by 86, we get 1 and a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 461.0
If we take 86 away from 106, we end up with 20.
Append the next digit (7) from the dividend to 20 and continue with: 207 / 86

On to step 6:
If we divide 207 by 86, we get 2 and a remainder of 35.
Write down 2 as next digit of the result. 
Result so far: 4612.0
Subtract 172 from 207 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 7:
The number 86 fits into 350 4 times, leaving a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 4612.4
Subtract 344 from 350 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
86 can be fit into 60 0 times, resulting in a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 4612.4
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 9:
If we divide 600 by 86, we get 6 and a remainder of 84.
The number 6 becomes the next digit in our result. 
Result so far: 4612.406
If we subtract 516 from 600, we get 84.
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 10:
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: 4612.4069
Subtracting 774 from 840 leaves us 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.

Step 11:
660 divided by 86 is 7 with a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 4612.40697
Deduct 602 from 660 and we're left 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.

Step 12:
The number 86 fits into 580 6 times, leaving a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 4612.406976
Subtracting 516 from 580 leaves us 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.

Advancing to step 13:
640 divided by 86 is 7 with a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 4612.4069767
If we take 602 away from 640, we end up with 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 14:
86 can be fit into 380 4 times, resulting in a remainder of 36.
The next digit of our result is 4. 
Result so far: 4612.40697674
If we subtract 344 from 380, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 4612.40697674, with a leftover of 3.6e-08.
