We look at the division of 677600 by 21 
We're looking to find how many times 21 goes into 677600.

Going ahead to step 1:
When dividing 6 by 21, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 21

Advancing to step 2:
21 goes into 67 3 times with a remainder of 4.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 4 after subtracting 63 from 67.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 21

Let's proceed to step 3:
The number 21 fits into 47 2 times, leaving a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
Subtracting 42 from 47 leaves us with 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 21

Moving on to step 4:
56 divided by 21 is 2 with a remainder of 14.
The next digit of our result is 2. 
Result so far: 322.0
Subtracting 42 from 56 leaves us with 14.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 21

Let's proceed to step 5:
The number 21 fits into 140 6 times, leaving a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 3226.0
If we take 126 away from 140, we end up with 14.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 21

Advancing to step 6:
If we divide 140 by 21, we get 6 and a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 32266.0
Subtract 126 from 140 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.

Advancing to step 7:
140 divided by 21 is 6 with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 32266.6
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.

Step 8:
21 goes into 140 6 times with a remainder of 14.
The next digit of our result is 6. 
Result so far: 32266.66
Subtracting 126 from 140 leaves us 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.

The final outcome is 32266.66, with a leftover of 0.014.
