We look at the division of 476145 by 21 
We want to divide 476145 by 21.

Going ahead 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
If we subtract 0 from 4, we get 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 21

Let's proceed to step 2:
21 can be fit into 47 2 times, resulting in a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 42 from 47 to get 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 21

Going ahead to step 3:
The number 21 fits into 56 2 times, leaving a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Subtract 42 from 56 to get 14.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 21

Moving on to step 4:
The number 21 fits into 141 6 times, leaving a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 226.0
If we subtract 126 from 141, we get 15.
Fetch the next digit (4) from the dividend, attach it to 15 and continue: 154 / 21

Step 5:
When dividing 154 by 21, we get 7 with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 2267.0
If we take 147 away from 154, we end up with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 21

Moving on to step 6:
75 divided by 21 is 3 with a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 22673.0
The remainder is 12 after subtracting 63 from 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
21 can be fit into 120 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 22673.5
Deduct 105 from 120 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 8:
21 can be fit into 150 7 times, resulting in a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 22673.57
Subtracting 147 from 150 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 9:
30 divided by 21 is 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 22673.571
The remainder is 9 after subtracting 21 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 10:
The number 21 fits into 90 4 times, leaving a remainder of 6.
The next digit of our result is 4. 
Result so far: 22673.5714
The remainder is 6 after subtracting 84 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 11:
21 goes into 60 2 times with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 22673.57142
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.

Moving on to step 12:
When dividing 180 by 21, we get 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 22673.571428
If we take 168 away from 180, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 13:
120 divided by 21 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 22673.5714285
Subtracting 105 from 120 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 14:
21 goes into 150 7 times with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 22673.57142857
Subtracting 147 from 150 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final outcome is 22673.57142857, with a leftover of 3e-09.
