46477736 ÷ 21 
Our goal is to divide 46477736 by 21.

Step 1:
If we divide 4 by 21, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 21

On to step 2:
21 can be fit into 46 2 times, resulting in a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 42 from 46, we get 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 21

Moving on to step 3:
21 can be fit into 44 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 22.0
Subtracting 42 from 44 leaves us with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 21

Let's proceed to step 4:
If we divide 27 by 21, we get 1 and a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 221.0
Subtract 21 from 27 to get 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 21

Going ahead to step 5:
The number 21 fits into 67 3 times, leaving a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 2213.0
If we subtract 63 from 67, we get 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 21

Step 6:
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: 22132.0
The remainder is 5 after subtracting 42 from 47.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 21

Advancing to step 7:
When dividing 53 by 21, we get 2 with a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 221322.0
Subtracting 42 from 53 leaves us with 11.
Grab the next digit (6) from the dividend, add it to 11, then carry on: 116 / 21

Going ahead to step 8:
116 divided by 21 is 5 with a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 2213225.0
The remainder is 11 after subtracting 105 from 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 9:
110 divided by 21 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 2213225.5
Subtracting 105 from 110 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.

On to step 10:
50 divided by 21 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 2213225.52
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 11:
The number 21 fits into 80 3 times, leaving a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 2213225.523
Deduct 63 from 80 and we're left with 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 12:
21 goes into 170 8 times with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 2213225.5238
If we subtract 168 from 170, we get 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 13:
When dividing 20 by 21, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 2213225.5238
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
If we divide 200 by 21, we get 9 and a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 2213225.523809
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.

Moving on to step 15:
When dividing 110 by 21, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 2213225.5238095
If we take 105 away from 110, we end up 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.

Step 16:
If we divide 50 by 21, we get 2 and a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 2213225.52380952
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.

Our division results in 2213225.52380952 with a remaining 8e-09.
