We're dividing 406475 by 86 
Let's see how many times 86 fits into 406475.

Going ahead to step 1:
When dividing 4 by 86, we get 0 with 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 (0) from the dividend after 4, then repeat: 40 / 86

Step 2:
The number 86 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Bring next digit (6) of the dividend behind the 40 and repeat the process: 406 / 86

Step 3:
86 can be fit into 406 4 times, resulting in a remainder of 62.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 344 from 406 to get 62.
Bring next digit (4) of the dividend behind the 62 and repeat the process: 624 / 86

Moving on to step 4:
If we divide 624 by 86, we get 7 and a remainder of 22.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
Subtract 602 from 624 to get 22.
Include the next digit (7) from the dividend after 22, then repeat: 227 / 86

Step 5:
When dividing 227 by 86, we get 2 with a remainder of 55.
Record the quotient 2 as the next digit in the result. 
Result so far: 472.0
Deduct 172 from 227 and we're left with 55.
Grab the next digit (5) from the dividend, add it to 55, then carry on: 555 / 86

Going ahead to step 6:
The number 86 fits into 555 6 times, leaving a remainder of 39.
Record the quotient 6 as the next digit in the result. 
Result so far: 4726.0
If we take 516 away from 555, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 7:
86 can be fit into 390 4 times, resulting in a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 4726.4
If we subtract 344 from 390, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 8:
If we divide 460 by 86, we get 5 and a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 4726.45
If we subtract 430 from 460, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 9:
If we divide 300 by 86, we get 3 and a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 4726.453
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 10:
86 can be fit into 420 4 times, resulting in a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 4726.4534
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.

Step 11:
760 divided by 86 is 8 with a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 4726.45348
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.

Step 12:
720 divided by 86 is 8 with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 4726.453488
If we take 688 away from 720, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 4726.453488 with a remaining 3.2e-06.
