Let's divide 406187 by 86
We want to figure out the number of times 406187 can be divided by 86.

Going ahead 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
If we subtract 0 from 4, we get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 86

Going ahead to step 2:
86 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Fetch the next digit (6) from the dividend, attach it to 40 and continue: 406 / 86

Going ahead to step 3:
When dividing 406 by 86, we get 4 with a remainder of 62.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 62 after subtracting 344 from 406.
Take the next digit (1) from the dividend and append it to 62, then repeat: 621 / 86

Going ahead to step 4:
86 goes into 621 7 times with a remainder of 19.
The next digit of our result is 7. 
Result so far: 47.0
Deduct 602 from 621 and we're left with 19.
Include the next digit (8) from the dividend after 19, then repeat: 198 / 86

Let's proceed to step 5:
When dividing 198 by 86, we get 2 with a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 472.0
If we take 172 away from 198, we end up with 26.
Include the next digit (7) from the dividend after 26, then repeat: 267 / 86

Advancing to step 6:
86 can be fit into 267 3 times, resulting in a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 4723.0
Subtract 258 from 267 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
86 can be fit into 90 1 times, resulting in a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 4723.1
Subtracting 86 from 90 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
When dividing 40 by 86, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 4723.1
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
86 can be fit into 400 4 times, resulting in a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 4723.104
If we subtract 344 from 400, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 10:
86 goes into 560 6 times with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 4723.1046
If we subtract 516 from 560, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 11:
86 goes into 440 5 times with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 4723.10465
Subtracting 430 from 440 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 12:
86 goes into 100 1 times with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 4723.104651
The remainder is 14 after subtracting 86 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 13:
When dividing 140 by 86, we get 1 with a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 4723.1046511
If we take 86 away from 140, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

After the division, we end up with 4723.1046511 and a remainder of 5.4e-07.
