21223808 divided by 431 
We want to divide 21223808 by 431.

Let's proceed to step 1:
431 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 431

Moving on to step 2:
431 can be fit into 21 0 times, resulting in a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 431

Moving on to step 3:
431 can be fit into 212 0 times, resulting in a remainder of 212.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 212 after subtracting 0 from 212.
Take the next digit (2) from the dividend and append it to 212, then repeat: 2122 / 431

On to step 4:
When dividing 2122 by 431, we get 4 with a remainder of 398.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 1724 from 2122 leaves us with 398.
Append the next digit (3) from the dividend to 398 and continue with: 3983 / 431

Advancing to step 5:
If we divide 3983 by 431, we get 9 and a remainder of 104.
Write down 9 as next digit of the result. 
Result so far: 49.0
Subtract 3879 from 3983 to get 104.
Append the next digit (8) from the dividend to 104 and continue with: 1048 / 431

Step 6:
When dividing 1048 by 431, we get 2 with a remainder of 186.
Write down 2 as next digit of the result. 
Result so far: 492.0
Deduct 862 from 1048 and we're left with 186.
Fetch the next digit (0) from the dividend, attach it to 186 and continue: 1860 / 431

Going ahead to step 7:
When dividing 1860 by 431, we get 4 with a remainder of 136.
Record the quotient 4 as the next digit in the result. 
Result so far: 4924.0
Deduct 1724 from 1860 and we're left with 136.
Append the next digit (8) from the dividend to 136 and continue with: 1368 / 431

Going ahead to step 8:
If we divide 1368 by 431, we get 3 and a remainder of 75.
Put 3 as the next digit of the answer. 
Result so far: 49243.0
If we take 1293 away from 1368, we end up with 75.
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 9:
If we divide 750 by 431, we get 1 and a remainder of 319.
The next digit of our result is 1. 
Result so far: 49243.1
If we subtract 431 from 750, we get 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Going ahead to step 10:
3190 divided by 431 is 7 with a remainder of 173.
Record the quotient 7 as the next digit in the result. 
Result so far: 49243.17
If we take 3017 away from 3190, we end up with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Going ahead to step 11:
If we divide 1730 by 431, we get 4 and a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 49243.174
The remainder is 6 after subtracting 1724 from 1730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 12:
431 can be fit into 60 0 times, resulting in a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 49243.174
If we subtract 0 from 60, we 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.

Step 13:
600 divided by 431 is 1 with a remainder of 169.
Put 1 as the next digit of the answer. 
Result so far: 49243.17401
If we take 431 away from 600, we end up with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Going ahead to step 14:
431 goes into 1690 3 times with a remainder of 397.
Write down 3 as next digit of the result. 
Result so far: 49243.174013
Subtract 1293 from 1690 to get 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Advancing to step 15:
431 goes into 3970 9 times with a remainder of 91.
Put 9 as the next digit of the answer. 
Result so far: 49243.1740139
The remainder is 91 after subtracting 3879 from 3970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Going ahead to step 16:
431 goes into 910 2 times with a remainder of 48.
The next digit of our result is 2. 
Result so far: 49243.17401392
If we subtract 862 from 910, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final result is 49243.17401392 with a remainder of 4.8e-08.
