Let's divide 36461915 by 21
Our goal is to divide 36461915 by 21.

Step 1:
21 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 21

Moving on to step 2:
When dividing 36 by 21, we get 1 with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 21 from 36 and we're left with 15.
Take the next digit (4) from the dividend and append it to 15, then repeat: 154 / 21

On to step 3:
The number 21 fits into 154 7 times, leaving a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtracting 147 from 154 leaves us with 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 21

Going ahead to step 4:
The number 21 fits into 76 3 times, leaving a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 173.0
The remainder is 13 after subtracting 63 from 76.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 21

Let's proceed to step 5:
When dividing 131 by 21, we get 6 with a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 1736.0
Deduct 126 from 131 and we're left with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 21

On to step 6:
When dividing 59 by 21, we get 2 with a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 17362.0
The remainder is 17 after subtracting 42 from 59.
Bring next digit (1) of the dividend behind the 17 and repeat the process: 171 / 21

Let's proceed to step 7:
When dividing 171 by 21, we get 8 with a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 173628.0
Deduct 168 from 171 and we're left with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 21

Advancing to step 8:
35 divided by 21 is 1 with a remainder of 14.
The next digit of our result is 1. 
Result so far: 1736281.0
Subtract 21 from 35 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
21 goes into 140 6 times with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 1736281.6
Deduct 126 from 140 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 10:
21 goes into 140 6 times with a remainder of 14.
The next digit of our result is 6. 
Result so far: 1736281.66
The remainder is 14 after subtracting 126 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 1736281.66 and a remainder of 0.014.
