Let's divide 21219057 by 363
Our goal is to divide 21219057 by 363.

Going ahead to step 1:
When dividing 2 by 363, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 363

Step 2:
363 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
If we take 0 away from 21, we end up with 21.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 363

Going ahead to step 3:
When dividing 212 by 363, we get 0 with a remainder of 212.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 212 to get 212.
Take the next digit (1) from the dividend and append it to 212, then repeat: 2121 / 363

Advancing to step 4:
When dividing 2121 by 363, we get 5 with a remainder of 306.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 1815 from 2121 to get 306.
Include the next digit (9) from the dividend after 306, then repeat: 3069 / 363

Advancing to step 5:
The number 363 fits into 3069 8 times, leaving a remainder of 165.
The next digit of our result is 8. 
Result so far: 58.0
If we subtract 2904 from 3069, we get 165.
Take the next digit (0) from the dividend and append it to 165, then repeat: 1650 / 363

Advancing to step 6:
363 goes into 1650 4 times with a remainder of 198.
Put 4 as the next digit of the answer. 
Result so far: 584.0
If we subtract 1452 from 1650, we get 198.
Grab the next digit (5) from the dividend, add it to 198, then carry on: 1985 / 363

Advancing to step 7:
The number 363 fits into 1985 5 times, leaving a remainder of 170.
Record the quotient 5 as the next digit in the result. 
Result so far: 5845.0
If we subtract 1815 from 1985, we get 170.
Include the next digit (7) from the dividend after 170, then repeat: 1707 / 363

Going ahead to step 8:
363 goes into 1707 4 times with a remainder of 255.
Use 4 as the next digit of our solution. 
Result so far: 58454.0
Subtracting 1452 from 1707 leaves us with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Advancing to step 9:
363 goes into 2550 7 times with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 58454.7
Deduct 2541 from 2550 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 10:
363 can be fit into 90 0 times, resulting in a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 58454.7
The remainder is 90 after subtracting 0 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 11:
When dividing 900 by 363, we get 2 with a remainder of 174.
Write down 2 as next digit of the result. 
Result so far: 58454.702
If we take 726 away from 900, we end up with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Moving on to step 12:
363 can be fit into 1740 4 times, resulting in a remainder of 288.
Write down 4 as next digit of the result. 
Result so far: 58454.7024
The remainder is 288 after subtracting 1452 from 1740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Step 13:
363 can be fit into 2880 7 times, resulting in a remainder of 339.
Record the quotient 7 as the next digit in the result. 
Result so far: 58454.70247
The remainder is 339 after subtracting 2541 from 2880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Going ahead to step 14:
If we divide 3390 by 363, we get 9 and a remainder of 123.
Record the quotient 9 as the next digit in the result. 
Result so far: 58454.702479
Subtracting 3267 from 3390 leaves us with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Advancing to step 15:
When dividing 1230 by 363, we get 3 with a remainder of 141.
Record the quotient 3 as the next digit in the result. 
Result so far: 58454.7024793
The remainder is 141 after subtracting 1089 from 1230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Step 16:
1410 divided by 363 is 3 with a remainder of 321.
Use 3 as the next digit of our solution. 
Result so far: 58454.70247933
If we take 1089 away from 1410, we end up with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

The quotient of the division is 58454.70247933, and the remainder is 3.21e-07.
