Let's divide 153806 by 51
We want to divide 153806 by 51.

Moving on 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
Deduct 0 from 1 and we're left with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 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.
Include the next digit (3) from the dividend after 15, then repeat: 153 / 51

Moving on to step 3:
If we divide 153 by 51, we get 3 and a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 153 from 153 to get 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 51

Advancing to step 4:
The number 51 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 51

Moving on to step 5:
80 divided by 51 is 1 with a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 301.0
Subtracting 51 from 80 leaves us with 29.
Bring next digit (6) of the dividend behind the 29 and repeat the process: 296 / 51

Step 6:
The number 51 fits into 296 5 times, leaving a remainder of 41.
Put 5 as the next digit of the answer. 
Result so far: 3015.0
Subtract 255 from 296 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 7:
The number 51 fits into 410 8 times, leaving a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 3015.8
Deduct 408 from 410 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
If we divide 20 by 51, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 3015.8
If we subtract 0 from 20, we 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.

Step 9:
51 can be fit into 200 3 times, resulting in a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 3015.803
Subtract 153 from 200 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 10:
If we divide 470 by 51, we get 9 and a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 3015.8039
The remainder is 11 after subtracting 459 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 11:
When dividing 110 by 51, we get 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 3015.80392
Deduct 102 from 110 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
51 goes into 80 1 times with a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 3015.803921
Subtract 51 from 80 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 13:
The number 51 fits into 290 5 times, leaving a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 3015.8039215
If we subtract 255 from 290, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 14:
51 can be fit into 350 6 times, resulting in a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 3015.80392156
If we subtract 306 from 350, 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.

After the division, we end up with 3015.80392156 and a remainder of 4.4e-08.
