We divide 852074 by 21
Our goal is to divide 852074 by 21.

On to step 1:
If we divide 8 by 21, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 21

Step 2:
21 can be fit into 85 4 times, resulting in a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 84 from 85 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 21

Step 3:
21 goes into 12 0 times with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
The remainder is 12 after subtracting 0 from 12.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 21

Going ahead to step 4:
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: 405.0
If we subtract 105 from 120, we get 15.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 21

Let's proceed to step 5:
The number 21 fits into 157 7 times, leaving a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 4057.0
Subtract 147 from 157 to get 10.
Bring next digit (4) of the dividend behind the 10 and repeat the process: 104 / 21

Let's proceed to step 6:
The number 21 fits into 104 4 times, leaving a remainder of 20.
The next digit of our result is 4. 
Result so far: 40574.0
If we take 84 away from 104, we end up 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.

Going ahead to step 7:
21 goes into 200 9 times with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 40574.9
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 8:
21 can be fit into 110 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 40574.95
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.

Let's proceed to step 9:
If we divide 50 by 21, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 40574.952
If we subtract 42 from 50, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
80 divided by 21 is 3 with a remainder of 17.
The next digit of our result is 3. 
Result so far: 40574.9523
Subtract 63 from 80 to get 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 11:
21 goes into 170 8 times with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 40574.95238
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.

Moving on to step 12:
21 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 40574.95238
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.

Advancing to step 13:
If we divide 200 by 21, we get 9 and a remainder of 11.
The next digit of our result is 9. 
Result so far: 40574.9523809
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 14:
110 divided by 21 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 40574.95238095
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.

In conclusion, the division gives 40574.95238095 with a balance of 5e-09.
