158546 divided by 51 
We're looking to find how many times 51 goes into 158546.

Going ahead to step 1:
51 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 51

On to step 2:
The number 51 fits into 15 0 times, leaving a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 51

On to step 3:
When dividing 158 by 51, we get 3 with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 153 away from 158, we end up with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 51

Going ahead to step 4:
If we divide 55 by 51, we get 1 and a remainder of 4.
The next digit of our result is 1. 
Result so far: 31.0
Subtract 51 from 55 to get 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 51

Moving on to step 5:
51 goes into 44 0 times with a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 310.0
Subtract 0 from 44 to get 44.
Append the next digit (6) from the dividend to 44 and continue with: 446 / 51

Step 6:
The number 51 fits into 446 8 times, leaving a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 3108.0
If we subtract 408 from 446, we get 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 7:
The number 51 fits into 380 7 times, leaving a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 3108.7
Subtracting 357 from 380 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 8:
If we divide 230 by 51, we get 4 and a remainder of 26.
The next digit of our result is 4. 
Result so far: 3108.74
Subtracting 204 from 230 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 9:
51 goes into 260 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 3108.745
The remainder is 5 after subtracting 255 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 10:
51 can be fit into 50 0 times, resulting in a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 3108.745
Subtracting 0 from 50 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:
The number 51 fits into 500 9 times, leaving a remainder of 41.
The next digit of our result is 9. 
Result so far: 3108.74509
Subtracting 459 from 500 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 12:
The number 51 fits into 410 8 times, leaving a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 3108.745098
If we subtract 408 from 410, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 13:
51 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 3108.745098
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 14:
If we divide 200 by 51, we get 3 and a remainder of 47.
The next digit of our result is 3. 
Result so far: 3108.74509803
Deduct 153 from 200 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The final result is 3108.74509803 with a remainder of 4.7e-08.
