We're dividing 21446186 by 485 
We want to figure out the number of times 21446186 can be divided by 485.

Advancing to step 1:
485 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 485

Advancing to step 2:
If we divide 21 by 485, we get 0 and a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Take the next digit (4) from the dividend and append it to 21, then repeat: 214 / 485

Let's proceed to step 3:
When dividing 214 by 485, we get 0 with a remainder of 214.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 214 to get 214.
Take the next digit (4) from the dividend and append it to 214, then repeat: 2144 / 485

Let's proceed to step 4:
When dividing 2144 by 485, we get 4 with a remainder of 204.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 1940 from 2144 to get 204.
Include the next digit (6) from the dividend after 204, then repeat: 2046 / 485

On to step 5:
If we divide 2046 by 485, we get 4 and a remainder of 106.
Put 4 as the next digit of the answer. 
Result so far: 44.0
Deduct 1940 from 2046 and we're left with 106.
Append the next digit (1) from the dividend to 106 and continue with: 1061 / 485

Step 6:
If we divide 1061 by 485, we get 2 and a remainder of 91.
The number 2 becomes the next digit in our result. 
Result so far: 442.0
Deduct 970 from 1061 and we're left with 91.
Bring next digit (8) of the dividend behind the 91 and repeat the process: 918 / 485

On to step 7:
485 can be fit into 918 1 times, resulting in a remainder of 433.
Record the quotient 1 as the next digit in the result. 
Result so far: 4421.0
Subtracting 485 from 918 leaves us with 433.
Include the next digit (6) from the dividend after 433, then repeat: 4336 / 485

On to step 8:
4336 divided by 485 is 8 with a remainder of 456.
The number 8 becomes the next digit in our result. 
Result so far: 44218.0
The remainder is 456 after subtracting 3880 from 4336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Moving on to step 9:
When dividing 4560 by 485, we get 9 with a remainder of 195.
Use 9 as the next digit of our solution. 
Result so far: 44218.9
Deduct 4365 from 4560 and we're left with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

On to step 10:
When dividing 1950 by 485, we get 4 with a remainder of 10.
The next digit of our result is 4. 
Result so far: 44218.94
If we subtract 1940 from 1950, 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.

Advancing to step 11:
100 divided by 485 is 0 with a remainder of 100.
The next digit of our result is 0. 
Result so far: 44218.94
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 12:
When dividing 1000 by 485, we get 2 with a remainder of 30.
Record the quotient 2 as the next digit in the result. 
Result so far: 44218.9402
If we take 970 away from 1000, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 13:
When dividing 300 by 485, we get 0 with a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 44218.9402
If we take 0 away from 300, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 14:
485 goes into 3000 6 times with a remainder of 90.
Use 6 as the next digit of our solution. 
Result so far: 44218.940206
Subtracting 2910 from 3000 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 15:
485 can be fit into 900 1 times, resulting in a remainder of 415.
Record the quotient 1 as the next digit in the result. 
Result so far: 44218.9402061
The remainder is 415 after subtracting 485 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Step 16:
485 goes into 4150 8 times with a remainder of 270.
Put 8 as the next digit of the answer. 
Result so far: 44218.94020618
If we subtract 3880 from 4150, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Our division results in 44218.94020618 with a remaining 2.7e-07.
