We're dividing 16977887 by 621 
We're looking to find how many times 621 goes into 16977887.

Let's proceed to step 1:
When dividing 1 by 621, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 621

Step 2:
621 can be fit into 16 0 times, resulting in a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Grab the next digit (9) from the dividend, add it to 16, then carry on: 169 / 621

Moving on to step 3:
When dividing 169 by 621, we get 0 with a remainder of 169.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 169, we get 169.
Include the next digit (7) from the dividend after 169, then repeat: 1697 / 621

On to step 4:
1697 divided by 621 is 2 with a remainder of 455.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 1242 from 1697 to get 455.
Take the next digit (7) from the dividend and append it to 455, then repeat: 4557 / 621

Advancing to step 5:
The number 621 fits into 4557 7 times, leaving a remainder of 210.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
If we subtract 4347 from 4557, we get 210.
Fetch the next digit (8) from the dividend, attach it to 210 and continue: 2108 / 621

Step 6:
2108 divided by 621 is 3 with a remainder of 245.
The next digit of our result is 3. 
Result so far: 273.0
Subtract 1863 from 2108 to get 245.
Append the next digit (8) from the dividend to 245 and continue with: 2458 / 621

Let's proceed to step 7:
The number 621 fits into 2458 3 times, leaving a remainder of 595.
The number 3 becomes the next digit in our result. 
Result so far: 2733.0
Subtracting 1863 from 2458 leaves us with 595.
Fetch the next digit (7) from the dividend, attach it to 595 and continue: 5957 / 621

Let's proceed to step 8:
621 goes into 5957 9 times with a remainder of 368.
Put 9 as the next digit of the answer. 
Result so far: 27339.0
Subtracting 5589 from 5957 leaves us with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Advancing to step 9:
3680 divided by 621 is 5 with a remainder of 575.
Write down 5 as next digit of the result. 
Result so far: 27339.5
If we subtract 3105 from 3680, we get 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Going ahead to step 10:
621 can be fit into 5750 9 times, resulting in a remainder of 161.
Put 9 as the next digit of the answer. 
Result so far: 27339.59
The remainder is 161 after subtracting 5589 from 5750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Let's proceed to step 11:
621 can be fit into 1610 2 times, resulting in a remainder of 368.
Put 2 as the next digit of the answer. 
Result so far: 27339.592
If we take 1242 away from 1610, we end up with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Let's proceed to step 12:
3680 divided by 621 is 5 with a remainder of 575.
The number 5 becomes the next digit in our result. 
Result so far: 27339.5925
If we take 3105 away from 3680, we end up with 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

On to step 13:
If we divide 5750 by 621, we get 9 and a remainder of 161.
Put 9 as the next digit of the answer. 
Result so far: 27339.59259
Subtract 5589 from 5750 to get 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

On to step 14:
1610 divided by 621 is 2 with a remainder of 368.
The next digit of our result is 2. 
Result so far: 27339.592592
The remainder is 368 after subtracting 1242 from 1610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Moving on to step 15:
621 goes into 3680 5 times with a remainder of 575.
Record the quotient 5 as the next digit in the result. 
Result so far: 27339.5925925
Deduct 3105 from 3680 and we're left with 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Let's proceed to step 16:
621 goes into 5750 9 times with a remainder of 161.
The next digit of our result is 9. 
Result so far: 27339.59259259
If we subtract 5589 from 5750, we get 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

After the division, we end up with 27339.59259259 and a remainder of 1.61e-07.
