We look at the division of 47913 by 21 
Our goal is to divide 47913 by 21.

Step 1:
21 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 21

Moving on to step 2:
If we divide 47 by 21, we get 2 and a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 42 from 47 and we're left with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 21

Advancing to step 3:
If we divide 59 by 21, we get 2 and a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we subtract 42 from 59, we get 17.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 21

Advancing to step 4:
171 divided by 21 is 8 with a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 228.0
If we take 168 away from 171, we end up with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 21

Let's proceed to step 5:
If we divide 33 by 21, we get 1 and a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 2281.0
Subtracting 21 from 33 leaves us 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.

Moving on to step 6:
The number 21 fits into 120 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 2281.5
Subtract 105 from 120 to 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.

Step 7:
If we divide 150 by 21, we get 7 and a remainder of 3.
The next digit of our result is 7. 
Result so far: 2281.57
If we take 147 away from 150, we end up 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.

On to step 8:
21 can be fit into 30 1 times, resulting in a remainder of 9.
The next digit of our result is 1. 
Result so far: 2281.571
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 9:
21 can be fit into 90 4 times, resulting in a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 2281.5714
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.

Moving on to step 10:
21 can be fit into 60 2 times, resulting in a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 2281.57142
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 11:
180 divided by 21 is 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 2281.571428
Subtracting 168 from 180 leaves us 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.

Advancing to step 12:
120 divided by 21 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 2281.5714285
Subtract 105 from 120 to 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.

Advancing to step 13:
When dividing 150 by 21, we get 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 2281.57142857
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.

The quotient of the division is 2281.57142857, and the remainder is 3e-09.
