Let's divide 205120 by 51
We're looking to find how many times 51 goes into 205120.

Going ahead to step 1:
The number 51 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 51

Step 2:
When dividing 20 by 51, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Grab the next digit (5) from the dividend, add it to 20, then carry on: 205 / 51

Moving on to step 3:
51 can be fit into 205 4 times, resulting in a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 204 from 205 leaves us with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 51

On to step 4:
11 divided by 51 is 0 with a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
Deduct 0 from 11 and we're left with 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 51

Let's proceed to step 5:
If we divide 112 by 51, we get 2 and a remainder of 10.
The next digit of our result is 2. 
Result so far: 402.0
The remainder is 10 after subtracting 102 from 112.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 51

Going ahead to step 6:
100 divided by 51 is 1 with a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 4021.0
Subtracting 51 from 100 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 7:
If we divide 490 by 51, we get 9 and a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 4021.9
Deduct 459 from 490 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 8:
51 goes into 310 6 times with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 4021.96
If we take 306 away from 310, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
51 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 4021.96
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
The number 51 fits into 400 7 times, leaving a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 4021.9607
If we subtract 357 from 400, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 11:
The number 51 fits into 430 8 times, leaving a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 4021.96078
Subtract 408 from 430 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 12:
The number 51 fits into 220 4 times, leaving a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 4021.960784
If we subtract 204 from 220, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
51 goes into 160 3 times with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 4021.9607843
If we take 153 away from 160, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 14:
The number 51 fits into 70 1 times, leaving a remainder of 19.
The next digit of our result is 1. 
Result so far: 4021.96078431
If we take 51 away from 70, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final outcome is 4021.96078431, with a leftover of 1.9e-08.
