206450 ÷ 51 
We're looking to find how many times 51 goes into 206450.

On to step 1:
51 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 51

Going ahead to step 2:
51 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Grab the next digit (6) from the dividend, add it to 20, then carry on: 206 / 51

Advancing to step 3:
206 divided by 51 is 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 204 from 206 to get 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 51

Let's proceed to step 4:
If we divide 24 by 51, we get 0 and a remainder of 24.
The next digit of our result is 0. 
Result so far: 40.0
If we subtract 0 from 24, we get 24.
Grab the next digit (5) from the dividend, add it to 24, then carry on: 245 / 51

Going ahead to step 5:
51 goes into 245 4 times with a remainder of 41.
Put 4 as the next digit of the answer. 
Result so far: 404.0
Subtract 204 from 245 to get 41.
Grab the next digit (0) from the dividend, add it to 41, then carry on: 410 / 51

Moving on to step 6:
51 can be fit into 410 8 times, resulting in a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 4048.0
Subtract 408 from 410 to 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 7:
If we divide 20 by 51, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 4048.0
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
200 divided by 51 is 3 with a remainder of 47.
The next digit of our result is 3. 
Result so far: 4048.03
The remainder is 47 after subtracting 153 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 9:
The number 51 fits into 470 9 times, leaving a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 4048.039
Deduct 459 from 470 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 10:
51 can be fit into 110 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 4048.0392
The remainder is 8 after subtracting 102 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
51 goes into 80 1 times with a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 4048.03921
If we take 51 away from 80, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 12:
If we divide 290 by 51, we get 5 and a remainder of 35.
The next digit of our result is 5. 
Result so far: 4048.039215
Deduct 255 from 290 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 13:
The number 51 fits into 350 6 times, leaving a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 4048.0392156
Deduct 306 from 350 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 14:
The number 51 fits into 440 8 times, leaving a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 4048.03921568
Deduct 408 from 440 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 4048.03921568, with a leftover of 3.2e-08.
