21228156 ÷ 631 
We want to divide 21228156 by 631.

Moving on to step 1:
631 can be fit into 2 0 times, resulting in 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.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 631

Step 2:
631 goes into 21 0 times with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 631

On to step 3:
631 goes into 212 0 times with a remainder of 212.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 212 leaves us with 212.
Bring next digit (2) of the dividend behind the 212 and repeat the process: 2122 / 631

Moving on to step 4:
If we divide 2122 by 631, we get 3 and a remainder of 229.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 1893 from 2122 leaves us with 229.
Take the next digit (8) from the dividend and append it to 229, then repeat: 2298 / 631

Let's proceed to step 5:
When dividing 2298 by 631, we get 3 with a remainder of 405.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Subtract 1893 from 2298 to get 405.
Fetch the next digit (1) from the dividend, attach it to 405 and continue: 4051 / 631

Let's proceed to step 6:
When dividing 4051 by 631, we get 6 with a remainder of 265.
Put 6 as the next digit of the answer. 
Result so far: 336.0
Subtracting 3786 from 4051 leaves us with 265.
Take the next digit (5) from the dividend and append it to 265, then repeat: 2655 / 631

Step 7:
2655 divided by 631 is 4 with a remainder of 131.
Record the quotient 4 as the next digit in the result. 
Result so far: 3364.0
Subtracting 2524 from 2655 leaves us with 131.
Bring next digit (6) of the dividend behind the 131 and repeat the process: 1316 / 631

Going ahead to step 8:
1316 divided by 631 is 2 with a remainder of 54.
Put 2 as the next digit of the answer. 
Result so far: 33642.0
Subtract 1262 from 1316 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 9:
540 divided by 631 is 0 with a remainder of 540.
Put 0 as the next digit of the answer. 
Result so far: 33642.0
If we take 0 away from 540, we end up with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Advancing to step 10:
If we divide 5400 by 631, we get 8 and a remainder of 352.
Put 8 as the next digit of the answer. 
Result so far: 33642.08
If we subtract 5048 from 5400, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

On to step 11:
631 can be fit into 3520 5 times, resulting in a remainder of 365.
The number 5 becomes the next digit in our result. 
Result so far: 33642.085
Subtract 3155 from 3520 to get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Advancing to step 12:
631 goes into 3650 5 times with a remainder of 495.
Use 5 as the next digit of our solution. 
Result so far: 33642.0855
The remainder is 495 after subtracting 3155 from 3650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

The quotient of the division is 33642.0855, and the remainder is 0.00495.
