We're dividing 51206221 by 333 
Let's see how many times 333 fits into 51206221.

Moving on to step 1:
5 divided by 333 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 333

Let's proceed to step 2:
If we divide 51 by 333, we get 0 and a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Append the next digit (2) from the dividend to 51 and continue with: 512 / 333

Step 3:
512 divided by 333 is 1 with a remainder of 179.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 333 from 512, we get 179.
Take the next digit (0) from the dividend and append it to 179, then repeat: 1790 / 333

On to step 4:
333 goes into 1790 5 times with a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we take 1665 away from 1790, we end up with 125.
Bring next digit (6) of the dividend behind the 125 and repeat the process: 1256 / 333

Step 5:
333 can be fit into 1256 3 times, resulting in a remainder of 257.
Put 3 as the next digit of the answer. 
Result so far: 153.0
If we subtract 999 from 1256, we get 257.
Include the next digit (2) from the dividend after 257, then repeat: 2572 / 333

Step 6:
333 can be fit into 2572 7 times, resulting in a remainder of 241.
The next digit of our result is 7. 
Result so far: 1537.0
Subtracting 2331 from 2572 leaves us with 241.
Grab the next digit (2) from the dividend, add it to 241, then carry on: 2412 / 333

Let's proceed to step 7:
2412 divided by 333 is 7 with a remainder of 81.
The number 7 becomes the next digit in our result. 
Result so far: 15377.0
Subtract 2331 from 2412 to get 81.
Append the next digit (1) from the dividend to 81 and continue with: 811 / 333

Let's proceed to step 8:
333 goes into 811 2 times with a remainder of 145.
Put 2 as the next digit of the answer. 
Result so far: 153772.0
Subtracting 666 from 811 leaves us with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Step 9:
1450 divided by 333 is 4 with a remainder of 118.
Put 4 as the next digit of the answer. 
Result so far: 153772.4
Deduct 1332 from 1450 and we're left with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Moving on to step 10:
The number 333 fits into 1180 3 times, leaving a remainder of 181.
Use 3 as the next digit of our solution. 
Result so far: 153772.43
Deduct 999 from 1180 and we're left with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Moving on to step 11:
1810 divided by 333 is 5 with a remainder of 145.
Write down 5 as next digit of the result. 
Result so far: 153772.435
If we subtract 1665 from 1810, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Going ahead to step 12:
When dividing 1450 by 333, we get 4 with a remainder of 118.
Write down 4 as next digit of the result. 
Result so far: 153772.4354
If we take 1332 away from 1450, we end up with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Let's proceed to step 13:
333 goes into 1180 3 times with a remainder of 181.
The next digit of our result is 3. 
Result so far: 153772.43543
If we subtract 999 from 1180, we get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Advancing to step 14:
333 goes into 1810 5 times with a remainder of 145.
The number 5 becomes the next digit in our result. 
Result so far: 153772.435435
If we take 1665 away from 1810, we end up with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Advancing to step 15:
333 can be fit into 1450 4 times, resulting in a remainder of 118.
The next digit of our result is 4. 
Result so far: 153772.4354354
If we take 1332 away from 1450, we end up with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Advancing to step 16:
The number 333 fits into 1180 3 times, leaving a remainder of 181.
Use 3 as the next digit of our solution. 
Result so far: 153772.43543543
If we subtract 999 from 1180, we get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

After the division, we end up with 153772.43543543 and a remainder of 1.81e-07.
