Let's divide 21102550 by 380
We want to figure out the number of times 21102550 can be divided by 380.

Let's proceed to step 1:
380 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 380

Step 2:
380 can be fit into 21 0 times, resulting in a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 380

Moving on to step 3:
211 divided by 380 is 0 with a remainder of 211.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 211 leaves us with 211.
Include the next digit (0) from the dividend after 211, then repeat: 2110 / 380

Let's proceed to step 4:
If we divide 2110 by 380, we get 5 and a remainder of 210.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 1900 from 2110, we get 210.
Fetch the next digit (2) from the dividend, attach it to 210 and continue: 2102 / 380

Advancing to step 5:
When dividing 2102 by 380, we get 5 with a remainder of 202.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
Subtract 1900 from 2102 to get 202.
Take the next digit (5) from the dividend and append it to 202, then repeat: 2025 / 380

Step 6:
When dividing 2025 by 380, we get 5 with a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 555.0
Subtract 1900 from 2025 to get 125.
Fetch the next digit (5) from the dividend, attach it to 125 and continue: 1255 / 380

Moving on to step 7:
The number 380 fits into 1255 3 times, leaving a remainder of 115.
Write down 3 as next digit of the result. 
Result so far: 5553.0
If we take 1140 away from 1255, we end up with 115.
Take the next digit (0) from the dividend and append it to 115, then repeat: 1150 / 380

Step 8:
380 can be fit into 1150 3 times, resulting in a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 55533.0
The remainder is 10 after subtracting 1140 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
100 divided by 380 is 0 with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 55533.0
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 10:
When dividing 1000 by 380, we get 2 with a remainder of 240.
The next digit of our result is 2. 
Result so far: 55533.02
Deduct 760 from 1000 and we're left with 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 11:
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: 55533.026
If we take 2280 away from 2400, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 12:
When dividing 1200 by 380, we get 3 with a remainder of 60.
The next digit of our result is 3. 
Result so far: 55533.0263
Subtract 1140 from 1200 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 13:
380 goes into 600 1 times with a remainder of 220.
The number 1 becomes the next digit in our result. 
Result so far: 55533.02631
If we subtract 380 from 600, we 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.

Going ahead to step 14:
When dividing 2200 by 380, we get 5 with a remainder of 300.
Write down 5 as next digit of the result. 
Result so far: 55533.026315
Subtract 1900 from 2200 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 15:
When dividing 3000 by 380, we get 7 with a remainder of 340.
The next digit of our result is 7. 
Result so far: 55533.0263157
The remainder is 340 after subtracting 2660 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 16:
380 can be fit into 3400 8 times, resulting in a remainder of 360.
The next digit of our result is 8. 
Result so far: 55533.02631578
Deduct 3040 from 3400 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Our division results in 55533.02631578 with a remaining 3.6e-07.
