We look at the division of 21290145 by 762 
We want to figure out the number of times 21290145 can be divided by 762.

Moving on to step 1:
The number 762 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 762

Advancing to step 2:
If we divide 21 by 762, we get 0 and a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Take the next digit (2) from the dividend and append it to 21, then repeat: 212 / 762

Going ahead to step 3:
If we divide 212 by 762, we get 0 and a remainder of 212.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 212, we get 212.
Take the next digit (9) from the dividend and append it to 212, then repeat: 2129 / 762

On to step 4:
When dividing 2129 by 762, we get 2 with a remainder of 605.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 605 after subtracting 1524 from 2129.
Include the next digit (0) from the dividend after 605, then repeat: 6050 / 762

Advancing to step 5:
762 goes into 6050 7 times with a remainder of 716.
Put 7 as the next digit of the answer. 
Result so far: 27.0
If we subtract 5334 from 6050, we get 716.
Grab the next digit (1) from the dividend, add it to 716, then carry on: 7161 / 762

Going ahead to step 6:
762 can be fit into 7161 9 times, resulting in a remainder of 303.
Put 9 as the next digit of the answer. 
Result so far: 279.0
Subtract 6858 from 7161 to get 303.
Append the next digit (4) from the dividend to 303 and continue with: 3034 / 762

Going ahead to step 7:
762 can be fit into 3034 3 times, resulting in a remainder of 748.
The next digit of our result is 3. 
Result so far: 2793.0
Deduct 2286 from 3034 and we're left with 748.
Grab the next digit (5) from the dividend, add it to 748, then carry on: 7485 / 762

Let's proceed to step 8:
762 can be fit into 7485 9 times, resulting in a remainder of 627.
Write down 9 as next digit of the result. 
Result so far: 27939.0
Deduct 6858 from 7485 and we're left with 627.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6270, and continue the process.

Going ahead to step 9:
6270 divided by 762 is 8 with a remainder of 174.
Use 8 as the next digit of our solution. 
Result so far: 27939.8
If we subtract 6096 from 6270, we get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Advancing to step 10:
762 can be fit into 1740 2 times, resulting in a remainder of 216.
Record the quotient 2 as the next digit in the result. 
Result so far: 27939.82
Subtract 1524 from 1740 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 11:
When dividing 2160 by 762, we get 2 with a remainder of 636.
Record the quotient 2 as the next digit in the result. 
Result so far: 27939.822
Deduct 1524 from 2160 and we're left with 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

The final result is 27939.822 with a remainder of 0.0636.
