21949857 ÷ 867 
Our goal is to divide 21949857 by 867.

Step 1:
The number 867 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 867

Let's proceed to step 2:
The number 867 fits into 21 0 times, leaving a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Bring next digit (9) of the dividend behind the 21 and repeat the process: 219 / 867

On to step 3:
867 can be fit into 219 0 times, resulting in a remainder of 219.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 219, we get 219.
Take the next digit (4) from the dividend and append it to 219, then repeat: 2194 / 867

On to step 4:
867 goes into 2194 2 times with a remainder of 460.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 1734 from 2194 and we're left with 460.
Bring next digit (9) of the dividend behind the 460 and repeat the process: 4609 / 867

Let's proceed to step 5:
4609 divided by 867 is 5 with a remainder of 274.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Deduct 4335 from 4609 and we're left with 274.
Append the next digit (8) from the dividend to 274 and continue with: 2748 / 867

Moving on to step 6:
If we divide 2748 by 867, we get 3 and a remainder of 147.
Record the quotient 3 as the next digit in the result. 
Result so far: 253.0
Deduct 2601 from 2748 and we're left with 147.
Grab the next digit (5) from the dividend, add it to 147, then carry on: 1475 / 867

Let's proceed to step 7:
When dividing 1475 by 867, we get 1 with a remainder of 608.
The next digit of our result is 1. 
Result so far: 2531.0
The remainder is 608 after subtracting 867 from 1475.
Bring next digit (7) of the dividend behind the 608 and repeat the process: 6087 / 867

Moving on to step 8:
867 goes into 6087 7 times with a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 25317.0
Subtract 6069 from 6087 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 9:
180 divided by 867 is 0 with a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 25317.0
If we subtract 0 from 180, we get 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 10:
The number 867 fits into 1800 2 times, leaving a remainder of 66.
The number 2 becomes the next digit in our result. 
Result so far: 25317.02
Subtracting 1734 from 1800 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 11:
867 goes into 660 0 times with a remainder of 660.
Write down 0 as next digit of the result. 
Result so far: 25317.02
Deduct 0 from 660 and we're left with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Moving on to step 12:
The number 867 fits into 6600 7 times, leaving a remainder of 531.
The next digit of our result is 7. 
Result so far: 25317.0207
If we subtract 6069 from 6600, we get 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

Step 13:
5310 divided by 867 is 6 with a remainder of 108.
Record the quotient 6 as the next digit in the result. 
Result so far: 25317.02076
Subtract 5202 from 5310 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 14:
The number 867 fits into 1080 1 times, leaving a remainder of 213.
Write down 1 as next digit of the result. 
Result so far: 25317.020761
Subtracting 867 from 1080 leaves us with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Going ahead to step 15:
867 goes into 2130 2 times with a remainder of 396.
The number 2 becomes the next digit in our result. 
Result so far: 25317.0207612
If we subtract 1734 from 2130, we get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Moving on to step 16:
If we divide 3960 by 867, we get 4 and a remainder of 492.
The next digit of our result is 4. 
Result so far: 25317.02076124
Subtracting 3468 from 3960 leaves us with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

The final result is 25317.02076124 with a remainder of 4.92e-07.
