We're dividing 46493186 by 21 
Our goal is to divide 46493186 by 21.

Going ahead to 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
If we take 0 away from 4, we end up with 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 21

Step 2:
46 divided by 21 is 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 42 from 46 leaves us with 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 21

Going ahead to step 3:
If we divide 44 by 21, we get 2 and a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
The remainder is 2 after subtracting 42 from 44.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 21

Let's proceed to step 4:
The number 21 fits into 29 1 times, leaving a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 221.0
Subtracting 21 from 29 leaves us with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 21

Advancing to step 5:
83 divided by 21 is 3 with a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 2213.0
Subtract 63 from 83 to get 20.
Fetch the next digit (1) from the dividend, attach it to 20 and continue: 201 / 21

On to step 6:
When dividing 201 by 21, we get 9 with a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 22139.0
The remainder is 12 after subtracting 189 from 201.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 21

On to step 7:
When dividing 128 by 21, we get 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 221396.0
If we take 126 away from 128, we end up with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 21

Step 8:
21 goes into 26 1 times with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 2213961.0
Subtracting 21 from 26 leaves us with 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.
Put 2 as the next digit of the answer. 
Result so far: 2213961.2
Subtracting 42 from 50 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
80 divided by 21 is 3 with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 2213961.23
If we subtract 63 from 80, we 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.

Going ahead to step 11:
170 divided by 21 is 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 2213961.238
If we take 168 away from 170, we end up 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.

Let's proceed to step 12:
When dividing 20 by 21, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 2213961.238
Subtract 0 from 20 to get 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 13:
When dividing 200 by 21, we get 9 with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 2213961.23809
Subtracting 189 from 200 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 14:
21 can be fit into 110 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 2213961.238095
Deduct 105 from 110 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 15:
50 divided by 21 is 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 2213961.2380952
Subtracting 42 from 50 leaves us with 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 16:
21 can be fit into 80 3 times, resulting in a remainder of 17.
The next digit of our result is 3. 
Result so far: 2213961.23809523
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.

After the division, we end up with 2213961.23809523 and a remainder of 1.7e-08.
