We look at the division of 158532 by 51 
Let's see how many times 51 fits into 158532.

Step 1:
51 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 51

Moving on to step 2:
The number 51 fits into 15 0 times, leaving a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 51

Let's proceed to step 3:
When dividing 158 by 51, we get 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 153 from 158 to get 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 51

Going ahead to step 4:
When dividing 55 by 51, we get 1 with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Deduct 51 from 55 and we're left with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 51

Going ahead to step 5:
When dividing 43 by 51, we get 0 with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 310.0
If we take 0 away from 43, we end up with 43.
Include the next digit (2) from the dividend after 43, then repeat: 432 / 51

Going ahead to step 6:
51 can be fit into 432 8 times, resulting in a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 3108.0
Subtract 408 from 432 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 7:
51 goes into 240 4 times with a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 3108.4
If we take 204 away from 240, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 8:
When dividing 360 by 51, we get 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 3108.47
Deduct 357 from 360 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 9:
The number 51 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 3108.47
If we subtract 0 from 30, 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.

On to step 10:
300 divided by 51 is 5 with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 3108.4705
The remainder is 45 after subtracting 255 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 11:
The number 51 fits into 450 8 times, leaving a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 3108.47058
If we take 408 away from 450, 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.

Step 12:
The number 51 fits into 420 8 times, leaving a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 3108.470588
If we take 408 away from 420, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 3108.470588, and the remainder is 1.2e-06.
