We're dividing 102240 by 51 
Our goal is to divide 102240 by 51.

Advancing to step 1:
51 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 51

Going ahead to step 2:
If we divide 10 by 51, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 51

Moving on to step 3:
51 can be fit into 102 2 times, resulting in a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 102 from 102 leaves us with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 51

Let's proceed to step 4:
2 divided by 51 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we subtract 0 from 2, we get 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 51

Step 5:
51 goes into 24 0 times with a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 200.0
Subtract 0 from 24 to get 24.
Take the next digit (0) from the dividend and append it to 24, then repeat: 240 / 51

On to step 6:
If we divide 240 by 51, we get 4 and a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 2004.0
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.

Moving on to step 7:
51 goes into 360 7 times with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 2004.7
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.

Step 8:
51 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 2004.7
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.

Moving on to step 9:
If we divide 300 by 51, we get 5 and a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 2004.705
If we take 255 away from 300, we end up 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 10:
51 goes into 450 8 times with a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 2004.7058
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.

Going ahead to step 11:
If we divide 420 by 51, we get 8 and a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 2004.70588
Subtract 408 from 420 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 2004.70588 with a balance of 1.2e-05.
