Let's divide 21783186 by 245
We want to divide 21783186 by 245.

Step 1:
2 divided by 245 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 245

On to step 2:
21 divided by 245 is 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Include the next digit (7) from the dividend after 21, then repeat: 217 / 245

On to step 3:
If we divide 217 by 245, we get 0 and a remainder of 217.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 217 and we're left with 217.
Append the next digit (8) from the dividend to 217 and continue with: 2178 / 245

Step 4:
245 goes into 2178 8 times with a remainder of 218.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 218 after subtracting 1960 from 2178.
Fetch the next digit (3) from the dividend, attach it to 218 and continue: 2183 / 245

On to step 5:
When dividing 2183 by 245, we get 8 with a remainder of 223.
Write down 8 as next digit of the result. 
Result so far: 88.0
Subtract 1960 from 2183 to get 223.
Grab the next digit (1) from the dividend, add it to 223, then carry on: 2231 / 245

Moving on to step 6:
245 can be fit into 2231 9 times, resulting in a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 889.0
The remainder is 26 after subtracting 2205 from 2231.
Grab the next digit (8) from the dividend, add it to 26, then carry on: 268 / 245

Moving on to step 7:
245 goes into 268 1 times with a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 8891.0
Subtract 245 from 268 to get 23.
Grab the next digit (6) from the dividend, add it to 23, then carry on: 236 / 245

Going ahead to step 8:
The number 245 fits into 236 0 times, leaving a remainder of 236.
The next digit of our result is 0. 
Result so far: 88910.0
If we take 0 away from 236, we end up with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Advancing to step 9:
2360 divided by 245 is 9 with a remainder of 155.
Put 9 as the next digit of the answer. 
Result so far: 88910.9
If we take 2205 away from 2360, we end up with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Going ahead to step 10:
1550 divided by 245 is 6 with a remainder of 80.
Use 6 as the next digit of our solution. 
Result so far: 88910.96
Subtract 1470 from 1550 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 11:
800 divided by 245 is 3 with a remainder of 65.
Write down 3 as next digit of the result. 
Result so far: 88910.963
If we subtract 735 from 800, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 12:
650 divided by 245 is 2 with a remainder of 160.
Write down 2 as next digit of the result. 
Result so far: 88910.9632
If we subtract 490 from 650, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 13:
1600 divided by 245 is 6 with a remainder of 130.
The next digit of our result is 6. 
Result so far: 88910.96326
The remainder is 130 after subtracting 1470 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 14:
If we divide 1300 by 245, we get 5 and a remainder of 75.
The next digit of our result is 5. 
Result so far: 88910.963265
The remainder is 75 after subtracting 1225 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 15:
If we divide 750 by 245, we get 3 and a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 88910.9632653
Subtracting 735 from 750 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 16:
245 goes into 150 0 times with a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 88910.9632653
The remainder is 150 after subtracting 0 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

After the division, we end up with 88910.9632653 and a remainder of 1.5e-07.
