Let's divide 26162647 by 21
We're looking to find how many times 21 goes into 26162647.

Step 1:
The number 21 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 21

Going ahead to step 2:
If we divide 26 by 21, we get 1 and a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 21 from 26 to get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 21

Step 3:
21 goes into 51 2 times with a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 42 away from 51, we end up with 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 21

Let's proceed to step 4:
96 divided by 21 is 4 with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 124.0
If we subtract 84 from 96, we get 12.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 21

Advancing to step 5:
21 can be fit into 122 5 times, resulting in a remainder of 17.
Record the quotient 5 as the next digit in the result. 
Result so far: 1245.0
If we subtract 105 from 122, we get 17.
Bring next digit (6) of the dividend behind the 17 and repeat the process: 176 / 21

Going ahead to step 6:
176 divided by 21 is 8 with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 12458.0
Deduct 168 from 176 and we're left with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 21

On to step 7:
When dividing 84 by 21, we get 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 124584.0
If we take 84 away from 84, we end up with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 21

Advancing to step 8:
21 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 1245840.0
Subtracting 0 from 7 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
70 divided by 21 is 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 1245840.3
If we take 63 away from 70, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 10:
The number 21 fits into 70 3 times, leaving a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 1245840.33
If we subtract 63 from 70, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The quotient of the division is 1245840.33, and the remainder is 0.007.
