Let's divide 166248 by 51
Our goal is to divide 166248 by 51.

On to step 1:
51 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 51

Moving on to step 2:
51 can be fit into 16 0 times, resulting in a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Take the next digit (6) from the dividend and append it to 16, then repeat: 166 / 51

Advancing to step 3:
The number 51 fits into 166 3 times, leaving a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 153 from 166 and we're left with 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 51

Let's proceed to step 4:
51 can be fit into 132 2 times, resulting in a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
If we subtract 102 from 132, we get 30.
Bring next digit (4) of the dividend behind the 30 and repeat the process: 304 / 51

Advancing to step 5:
When dividing 304 by 51, we get 5 with a remainder of 49.
Use 5 as the next digit of our solution. 
Result so far: 325.0
Deduct 255 from 304 and we're left with 49.
Bring next digit (8) of the dividend behind the 49 and repeat the process: 498 / 51

Step 6:
The number 51 fits into 498 9 times, leaving a remainder of 39.
The number 9 becomes the next digit in our result. 
Result so far: 3259.0
The remainder is 39 after subtracting 459 from 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 7:
If we divide 390 by 51, we get 7 and a remainder of 33.
Write down 7 as next digit of the result. 
Result so far: 3259.7
Subtracting 357 from 390 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 8:
The number 51 fits into 330 6 times, leaving a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 3259.76
If we subtract 306 from 330, we 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.

Step 9:
The number 51 fits into 240 4 times, leaving a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 3259.764
Subtracting 204 from 240 leaves us 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.

Step 10:
360 divided by 51 is 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 3259.7647
Subtract 357 from 360 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 11:
When dividing 30 by 51, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 3259.7647
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 12:
When dividing 300 by 51, we get 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 3259.764705
Deduct 255 from 300 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 13:
51 goes into 450 8 times with a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 3259.7647058
The remainder is 42 after subtracting 408 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 14:
When dividing 420 by 51, we get 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 3259.76470588
Subtracting 408 from 420 leaves us 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.

After the division, we end up with 3259.76470588 and a remainder of 1.2e-08.
