Let's divide 51020818 by 380
Our goal is to divide 51020818 by 380.

On to step 1:
5 divided by 380 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 380

Moving on to step 2:
380 can be fit into 51 0 times, resulting in a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Append the next digit (0) from the dividend to 51 and continue with: 510 / 380

Advancing to step 3:
When dividing 510 by 380, we get 1 with a remainder of 130.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 380 from 510 leaves us with 130.
Fetch the next digit (2) from the dividend, attach it to 130 and continue: 1302 / 380

Let's proceed to step 4:
The number 380 fits into 1302 3 times, leaving a remainder of 162.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 1140 from 1302 leaves us with 162.
Include the next digit (0) from the dividend after 162, then repeat: 1620 / 380

Step 5:
The number 380 fits into 1620 4 times, leaving a remainder of 100.
Put 4 as the next digit of the answer. 
Result so far: 134.0
Deduct 1520 from 1620 and we're left with 100.
Take the next digit (8) from the dividend and append it to 100, then repeat: 1008 / 380

Step 6:
1008 divided by 380 is 2 with a remainder of 248.
Record the quotient 2 as the next digit in the result. 
Result so far: 1342.0
The remainder is 248 after subtracting 760 from 1008.
Bring next digit (1) of the dividend behind the 248 and repeat the process: 2481 / 380

Moving on to step 7:
380 can be fit into 2481 6 times, resulting in a remainder of 201.
Use 6 as the next digit of our solution. 
Result so far: 13426.0
If we take 2280 away from 2481, we end up with 201.
Take the next digit (8) from the dividend and append it to 201, then repeat: 2018 / 380

Going ahead to step 8:
When dividing 2018 by 380, we get 5 with a remainder of 118.
Record the quotient 5 as the next digit in the result. 
Result so far: 134265.0
Subtract 1900 from 2018 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

On to step 9:
The number 380 fits into 1180 3 times, leaving a remainder of 40.
Put 3 as the next digit of the answer. 
Result so far: 134265.3
Deduct 1140 from 1180 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
When dividing 400 by 380, we get 1 with a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 134265.31
The remainder is 20 after subtracting 380 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 11:
380 goes into 200 0 times with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 134265.31
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 12:
The number 380 fits into 2000 5 times, leaving a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 134265.3105
If we take 1900 away from 2000, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 13:
The number 380 fits into 1000 2 times, leaving a remainder of 240.
The number 2 becomes the next digit in our result. 
Result so far: 134265.31052
Subtract 760 from 1000 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 14:
When dividing 2400 by 380, we get 6 with a remainder of 120.
The number 6 becomes the next digit in our result. 
Result so far: 134265.310526
If we subtract 2280 from 2400, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 15:
380 can be fit into 1200 3 times, resulting in a remainder of 60.
The next digit of our result is 3. 
Result so far: 134265.3105263
Subtracting 1140 from 1200 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 16:
380 goes into 600 1 times with a remainder of 220.
Put 1 as the next digit of the answer. 
Result so far: 134265.31052631
Subtract 380 from 600 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

After the division, we end up with 134265.31052631 and a remainder of 2.2e-07.
