We look at the division of 27673677 by 645 
We're looking to find how many times 645 goes into 27673677.

Moving on to step 1:
2 divided by 645 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 645

Step 2:
If we divide 27 by 645, we get 0 and a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 27, we get 27.
Take the next digit (6) from the dividend and append it to 27, then repeat: 276 / 645

Moving on to step 3:
645 can be fit into 276 0 times, resulting in a remainder of 276.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 276, we get 276.
Fetch the next digit (7) from the dividend, attach it to 276 and continue: 2767 / 645

Step 4:
645 can be fit into 2767 4 times, resulting in a remainder of 187.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 2580 from 2767 to get 187.
Grab the next digit (3) from the dividend, add it to 187, then carry on: 1873 / 645

Let's proceed to step 5:
645 goes into 1873 2 times with a remainder of 583.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
If we take 1290 away from 1873, we end up with 583.
Grab the next digit (6) from the dividend, add it to 583, then carry on: 5836 / 645

Step 6:
5836 divided by 645 is 9 with a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 429.0
If we subtract 5805 from 5836, we get 31.
Take the next digit (7) from the dividend and append it to 31, then repeat: 317 / 645

Step 7:
645 can be fit into 317 0 times, resulting in a remainder of 317.
Put 0 as the next digit of the answer. 
Result so far: 4290.0
Deduct 0 from 317 and we're left with 317.
Append the next digit (7) from the dividend to 317 and continue with: 3177 / 645

On to step 8:
645 can be fit into 3177 4 times, resulting in a remainder of 597.
Use 4 as the next digit of our solution. 
Result so far: 42904.0
If we take 2580 away from 3177, we end up with 597.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5970, and continue the process.

Going ahead to step 9:
When dividing 5970 by 645, we get 9 with a remainder of 165.
The next digit of our result is 9. 
Result so far: 42904.9
The remainder is 165 after subtracting 5805 from 5970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

On to step 10:
The number 645 fits into 1650 2 times, leaving a remainder of 360.
The number 2 becomes the next digit in our result. 
Result so far: 42904.92
If we subtract 1290 from 1650, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 11:
645 can be fit into 3600 5 times, resulting in a remainder of 375.
Record the quotient 5 as the next digit in the result. 
Result so far: 42904.925
If we take 3225 away from 3600, we end up with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Advancing to step 12:
If we divide 3750 by 645, we get 5 and a remainder of 525.
The next digit of our result is 5. 
Result so far: 42904.9255
If we take 3225 away from 3750, we end up with 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

The quotient of the division is 42904.9255, and the remainder is 0.00525.
