461536 divided by 21 
We want to figure out the number of times 461536 can be divided by 21.

Step 1:
21 can be fit into 4 0 times, resulting in 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.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 21

Step 2:
When dividing 46 by 21, we get 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 42 away from 46, we end up with 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 21

Moving on to step 3:
The number 21 fits into 41 1 times, leaving a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 21.0
The remainder is 20 after subtracting 21 from 41.
Fetch the next digit (5) from the dividend, attach it to 20 and continue: 205 / 21

Going ahead to step 4:
205 divided by 21 is 9 with a remainder of 16.
Write down 9 as next digit of the result. 
Result so far: 219.0
The remainder is 16 after subtracting 189 from 205.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 21

On to step 5:
The number 21 fits into 163 7 times, leaving a remainder of 16.
Put 7 as the next digit of the answer. 
Result so far: 2197.0
Deduct 147 from 163 and we're left with 16.
Take the next digit (6) from the dividend and append it to 16, then repeat: 166 / 21

Moving on to step 6:
21 goes into 166 7 times with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 21977.0
The remainder is 19 after subtracting 147 from 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
If we divide 190 by 21, we get 9 and a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 21977.9
If we subtract 189 from 190, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 8:
When dividing 10 by 21, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 21977.9
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
When dividing 100 by 21, we get 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 21977.904
If we take 84 away from 100, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
If we divide 160 by 21, we get 7 and a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 21977.9047
Subtract 147 from 160 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 11:
If we divide 130 by 21, we get 6 and a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 21977.90476
The remainder is 4 after subtracting 126 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 12:
The number 21 fits into 40 1 times, leaving a remainder of 19.
The next digit of our result is 1. 
Result so far: 21977.904761
Deduct 21 from 40 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 13:
If we divide 190 by 21, we get 9 and a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 21977.9047619
If we take 189 away from 190, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 14:
21 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 21977.9047619
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 21977.9047619 with a balance of 1e-08.
