We look at the division of 21589648 by 949 
We want to divide 21589648 by 949.

Step 1:
949 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 949

On to step 2:
949 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
Subtract 0 from 21 to get 21.
Append the next digit (5) from the dividend to 21 and continue with: 215 / 949

Step 3:
949 can be fit into 215 0 times, resulting in a remainder of 215.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 215 and we're left with 215.
Bring next digit (8) of the dividend behind the 215 and repeat the process: 2158 / 949

Advancing to step 4:
949 goes into 2158 2 times with a remainder of 260.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 260 after subtracting 1898 from 2158.
Grab the next digit (9) from the dividend, add it to 260, then carry on: 2609 / 949

Moving on to step 5:
When dividing 2609 by 949, we get 2 with a remainder of 711.
Use 2 as the next digit of our solution. 
Result so far: 22.0
Subtract 1898 from 2609 to get 711.
Fetch the next digit (6) from the dividend, attach it to 711 and continue: 7116 / 949

Advancing to step 6:
When dividing 7116 by 949, we get 7 with a remainder of 473.
The number 7 becomes the next digit in our result. 
Result so far: 227.0
If we take 6643 away from 7116, we end up with 473.
Bring next digit (4) of the dividend behind the 473 and repeat the process: 4734 / 949

Going ahead to step 7:
When dividing 4734 by 949, we get 4 with a remainder of 938.
Write down 4 as next digit of the result. 
Result so far: 2274.0
If we take 3796 away from 4734, we end up with 938.
Append the next digit (8) from the dividend to 938 and continue with: 9388 / 949

Let's proceed to step 8:
The number 949 fits into 9388 9 times, leaving a remainder of 847.
The number 9 becomes the next digit in our result. 
Result so far: 22749.0
Subtracting 8541 from 9388 leaves us with 847.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8470, and continue the process.

Advancing to step 9:
949 can be fit into 8470 8 times, resulting in a remainder of 878.
Record the quotient 8 as the next digit in the result. 
Result so far: 22749.8
If we take 7592 away from 8470, we end up with 878.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8780, and continue the process.

Let's proceed to step 10:
When dividing 8780 by 949, we get 9 with a remainder of 239.
Record the quotient 9 as the next digit in the result. 
Result so far: 22749.89
Subtract 8541 from 8780 to get 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Advancing to step 11:
When dividing 2390 by 949, we get 2 with a remainder of 492.
The next digit of our result is 2. 
Result so far: 22749.892
Subtracting 1898 from 2390 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.

Moving on to step 12:
949 goes into 4920 5 times with a remainder of 175.
Put 5 as the next digit of the answer. 
Result so far: 22749.8925
Subtract 4745 from 4920 to get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 13:
If we divide 1750 by 949, we get 1 and a remainder of 801.
Put 1 as the next digit of the answer. 
Result so far: 22749.89251
Subtracting 949 from 1750 leaves us with 801.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8010, and continue the process.

On to step 14:
If we divide 8010 by 949, we get 8 and a remainder of 418.
The next digit of our result is 8. 
Result so far: 22749.892518
Subtracting 7592 from 8010 leaves us with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Advancing to step 15:
If we divide 4180 by 949, we get 4 and a remainder of 384.
Record the quotient 4 as the next digit in the result. 
Result so far: 22749.8925184
The remainder is 384 after subtracting 3796 from 4180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Going ahead to step 16:
If we divide 3840 by 949, we get 4 and a remainder of 44.
The next digit of our result is 4. 
Result so far: 22749.89251844
Deduct 3796 from 3840 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Our division results in 22749.89251844 with a remaining 4.4e-08.
