Let's divide 21144129 by 245
Let's see how many times 245 fits into 21144129.

Step 1:
245 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
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

Going ahead to step 2:
245 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
Deduct 0 from 21 and we're left with 21.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 245

Advancing to step 3:
When dividing 211 by 245, we get 0 with a remainder of 211.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 211 leaves us with 211.
Append the next digit (4) from the dividend to 211 and continue with: 2114 / 245

Going ahead to step 4:
If we divide 2114 by 245, we get 8 and a remainder of 154.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 1960 away from 2114, we end up with 154.
Include the next digit (4) from the dividend after 154, then repeat: 1544 / 245

Moving on to step 5:
1544 divided by 245 is 6 with a remainder of 74.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
If we take 1470 away from 1544, we end up with 74.
Take the next digit (1) from the dividend and append it to 74, then repeat: 741 / 245

Going ahead to step 6:
If we divide 741 by 245, we get 3 and a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 863.0
If we take 735 away from 741, we end up with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 245

Step 7:
245 can be fit into 62 0 times, resulting in a remainder of 62.
Put 0 as the next digit of the answer. 
Result so far: 8630.0
Subtract 0 from 62 to get 62.
Bring next digit (9) of the dividend behind the 62 and repeat the process: 629 / 245

On to step 8:
When dividing 629 by 245, we get 2 with a remainder of 139.
Record the quotient 2 as the next digit in the result. 
Result so far: 86302.0
Subtract 490 from 629 to get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Advancing to step 9:
245 goes into 1390 5 times with a remainder of 165.
Write down 5 as next digit of the result. 
Result so far: 86302.5
Subtracting 1225 from 1390 leaves us with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Going ahead to step 10:
When dividing 1650 by 245, we get 6 with a remainder of 180.
Put 6 as the next digit of the answer. 
Result so far: 86302.56
If we take 1470 away from 1650, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 11:
1800 divided by 245 is 7 with a remainder of 85.
Put 7 as the next digit of the answer. 
Result so far: 86302.567
If we subtract 1715 from 1800, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 12:
If we divide 850 by 245, we get 3 and a remainder of 115.
Record the quotient 3 as the next digit in the result. 
Result so far: 86302.5673
Subtract 735 from 850 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 13:
The number 245 fits into 1150 4 times, leaving a remainder of 170.
Write down 4 as next digit of the result. 
Result so far: 86302.56734
Subtracting 980 from 1150 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 14:
If we divide 1700 by 245, we get 6 and a remainder of 230.
The next digit of our result is 6. 
Result so far: 86302.567346
The remainder is 230 after subtracting 1470 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 15:
If we divide 2300 by 245, we get 9 and a remainder of 95.
Record the quotient 9 as the next digit in the result. 
Result so far: 86302.5673469
Subtracting 2205 from 2300 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Moving on to step 16:
When dividing 950 by 245, we get 3 with a remainder of 215.
Write down 3 as next digit of the result. 
Result so far: 86302.56734693
Subtracting 735 from 950 leaves us with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

The final outcome is 86302.56734693, with a leftover of 2.15e-07.
