Let's divide 461151 by 21
We want to figure out the number of times 461151 can be divided by 21.

Going ahead to step 1:
When dividing 4 by 21, we get 0 with 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.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 21

Step 2:
46 divided by 21 is 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.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 21

Advancing to step 3:
When dividing 41 by 21, we get 1 with a remainder of 20.
The next digit of our result is 1. 
Result so far: 21.0
Subtracting 21 from 41 leaves us with 20.
Fetch the next digit (1) from the dividend, attach it to 20 and continue: 201 / 21

Let's proceed to step 4:
21 goes into 201 9 times with a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 219.0
The remainder is 12 after subtracting 189 from 201.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 21

Moving on to step 5:
21 goes into 125 5 times with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 2195.0
If we take 105 away from 125, we end up with 20.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 21

Going ahead to step 6:
When dividing 201 by 21, we get 9 with a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 21959.0
Subtracting 189 from 201 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.

Going ahead to step 7:
The number 21 fits into 120 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 21959.5
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.

Going ahead to step 8:
21 can be fit into 150 7 times, resulting in a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 21959.57
If we subtract 147 from 150, we 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.

Step 9:
If we divide 30 by 21, we get 1 and a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 21959.571
Deduct 21 from 30 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 10:
21 goes into 90 4 times with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 21959.5714
Subtract 84 from 90 to get 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 11:
21 goes into 60 2 times with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 21959.57142
If we take 42 away from 60, we end up 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.

Step 12:
21 goes into 180 8 times with a remainder of 12.
The next digit of our result is 8. 
Result so far: 21959.571428
If we subtract 168 from 180, we get 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 13:
If we divide 120 by 21, we get 5 and a remainder of 15.
The next digit of our result is 5. 
Result so far: 21959.5714285
If we take 105 away from 120, we end up 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: 21959.57142857
Deduct 147 from 150 and we're left 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.

After the division, we end up with 21959.57142857 and a remainder of 3e-09.
