We divide 5408000 by 21
We want to divide 5408000 by 21.

Let's proceed to step 1:
The number 21 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 21

Step 2:
When dividing 54 by 21, we get 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 42 from 54 to get 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 21

Moving on to step 3:
When dividing 120 by 21, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
If we take 105 away from 120, we end up with 15.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 21

Going ahead to step 4:
21 can be fit into 158 7 times, resulting in a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 257.0
Subtract 147 from 158 to get 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 21

Let's proceed to step 5:
110 divided by 21 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 2575.0
If we take 105 away from 110, we end up with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 21

Advancing to step 6:
When dividing 50 by 21, we get 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 25752.0
Subtracting 42 from 50 leaves us with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 21

Step 7:
When dividing 80 by 21, we get 3 with a remainder of 17.
The next digit of our result is 3. 
Result so far: 257523.0
The remainder is 17 after subtracting 63 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 8:
21 goes into 170 8 times with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 257523.8
Deduct 168 from 170 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
When dividing 20 by 21, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 257523.8
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
200 divided by 21 is 9 with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 257523.809
If we subtract 189 from 200, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 11:
If we divide 110 by 21, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 257523.8095
Subtract 105 from 110 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 12:
21 goes into 50 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 257523.80952
Deduct 42 from 50 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 13:
21 goes into 80 3 times with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 257523.809523
If we take 63 away from 80, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 14:
When dividing 170 by 21, we get 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 257523.8095238
If we subtract 168 from 170, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 15:
If we divide 20 by 21, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 257523.8095238
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 257523.8095238, and the remainder is 2e-08.
