152854 divided by 21 
We want to divide 152854 by 21.

Let's proceed to step 1:
21 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 21

Going ahead to step 2:
When dividing 15 by 21, we get 0 with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Grab the next digit (2) from the dividend, add it to 15, then carry on: 152 / 21

On to step 3:
The number 21 fits into 152 7 times, leaving a remainder of 5.
The next digit of our result is 7. 
Result so far: 7.0
If we take 147 away from 152, we end up with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 21

Let's proceed to step 4:
58 divided by 21 is 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 72.0
If we subtract 42 from 58, we get 16.
Fetch the next digit (5) from the dividend, attach it to 16 and continue: 165 / 21

Step 5:
165 divided by 21 is 7 with a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 727.0
The remainder is 18 after subtracting 147 from 165.
Append the next digit (4) from the dividend to 18 and continue with: 184 / 21

Step 6:
184 divided by 21 is 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 7278.0
Deduct 168 from 184 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 7:
21 can be fit into 160 7 times, resulting in a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 7278.7
If we subtract 147 from 160, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 8:
21 can be fit into 130 6 times, resulting in a remainder of 4.
The next digit of our result is 6. 
Result so far: 7278.76
Deduct 126 from 130 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
If we divide 40 by 21, we get 1 and a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 7278.761
Deduct 21 from 40 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 10:
21 can be fit into 190 9 times, resulting in a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 7278.7619
If we take 189 away from 190, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 11:
If we divide 10 by 21, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 7278.7619
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
The number 21 fits into 100 4 times, leaving a remainder of 16.
The next digit of our result is 4. 
Result so far: 7278.761904
Subtracting 84 from 100 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
21 can be fit into 160 7 times, resulting in a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 7278.7619047
Subtract 147 from 160 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 14:
If we divide 130 by 21, we get 6 and a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 7278.76190476
Deduct 126 from 130 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 7278.76190476 and a remainder of 4e-09.
