Let's divide 158604 by 86
We want to divide 158604 by 86.

On to step 1:
When dividing 1 by 86, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 86

Moving on to step 2:
If we divide 15 by 86, we get 0 and a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 86

Let's proceed to step 3:
When dividing 158 by 86, we get 1 with a remainder of 72.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 86 from 158, we get 72.
Append the next digit (6) from the dividend to 72 and continue with: 726 / 86

Going ahead to step 4:
When dividing 726 by 86, we get 8 with a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
The remainder is 38 after subtracting 688 from 726.
Grab the next digit (0) from the dividend, add it to 38, then carry on: 380 / 86

Let's proceed to step 5:
If we divide 380 by 86, we get 4 and a remainder of 36.
The next digit of our result is 4. 
Result so far: 184.0
The remainder is 36 after subtracting 344 from 380.
Include the next digit (4) from the dividend after 36, then repeat: 364 / 86

Let's proceed to step 6:
When dividing 364 by 86, we get 4 with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 1844.0
Subtracting 344 from 364 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
86 goes into 200 2 times with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 1844.2
If we subtract 172 from 200, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 8:
If we divide 280 by 86, we get 3 and a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 1844.23
If we take 258 away from 280, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
86 goes into 220 2 times with a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 1844.232
If we subtract 172 from 220, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 10:
86 can be fit into 480 5 times, resulting in a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 1844.2325
Subtracting 430 from 480 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
86 goes into 500 5 times with a remainder of 70.
The next digit of our result is 5. 
Result so far: 1844.23255
Deduct 430 from 500 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 1844.23255 with a remaining 7e-05.
