Let's divide 476010 by 21
We're looking to find how many times 21 goes into 476010.

Advancing to step 1:
The number 21 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 21

Let's proceed to step 2:
The number 21 fits into 47 2 times, leaving a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 42 away from 47, we end up with 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 21

Step 3:
If we divide 56 by 21, we get 2 and a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 22.0
Subtract 42 from 56 to get 14.
Take the next digit (0) from the dividend and append it to 14, then repeat: 140 / 21

Let's proceed to step 4:
When dividing 140 by 21, we get 6 with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 226.0
The remainder is 14 after subtracting 126 from 140.
Append the next digit (1) from the dividend to 14 and continue with: 141 / 21

On to step 5:
141 divided by 21 is 6 with a remainder of 15.
The number 6 becomes the next digit in our result. 
Result so far: 2266.0
If we subtract 126 from 141, we get 15.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 21

Going ahead to step 6:
If we divide 150 by 21, we get 7 and a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 22667.0
If we subtract 147 from 150, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
When dividing 30 by 21, we get 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 22667.1
Subtract 21 from 30 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 8:
90 divided by 21 is 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 22667.14
Subtracting 84 from 90 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 9:
21 can be fit into 60 2 times, resulting in a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 22667.142
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 10:
180 divided by 21 is 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 22667.1428
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 11:
21 goes into 120 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 22667.14285
If we subtract 105 from 120, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 12:
The number 21 fits into 150 7 times, leaving a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 22667.142857
Subtract 147 from 150 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 13:
When dividing 30 by 21, we get 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 22667.1428571
If we subtract 21 from 30, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 14:
The number 21 fits into 90 4 times, leaving a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 22667.14285714
Subtract 84 from 90 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 22667.14285714 with a remaining 6e-09.
