We look at the division of 1881108 by 621 
We want to divide 1881108 by 621.

Step 1:
1 divided by 621 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 621

Advancing to step 2:
If we divide 18 by 621, we get 0 and a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Include the next digit (8) from the dividend after 18, then repeat: 188 / 621

On to step 3:
If we divide 188 by 621, we get 0 and a remainder of 188.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 188 leaves us with 188.
Include the next digit (1) from the dividend after 188, then repeat: 1881 / 621

Step 4:
If we divide 1881 by 621, we get 3 and a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 1863 from 1881 and we're left with 18.
Grab the next digit (1) from the dividend, add it to 18, then carry on: 181 / 621

Step 5:
621 can be fit into 181 0 times, resulting in a remainder of 181.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
Subtracting 0 from 181 leaves us with 181.
Bring next digit (0) of the dividend behind the 181 and repeat the process: 1810 / 621

Let's proceed to step 6:
The number 621 fits into 1810 2 times, leaving a remainder of 568.
Write down 2 as next digit of the result. 
Result so far: 302.0
If we take 1242 away from 1810, we end up with 568.
Include the next digit (8) from the dividend after 568, then repeat: 5688 / 621

On to step 7:
If we divide 5688 by 621, we get 9 and a remainder of 99.
The number 9 becomes the next digit in our result. 
Result so far: 3029.0
Deduct 5589 from 5688 and we're left with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Moving on to step 8:
990 divided by 621 is 1 with a remainder of 369.
The number 1 becomes the next digit in our result. 
Result so far: 3029.1
If we subtract 621 from 990, we get 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

On to step 9:
3690 divided by 621 is 5 with a remainder of 585.
The next digit of our result is 5. 
Result so far: 3029.15
If we take 3105 away from 3690, we end up with 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Step 10:
621 can be fit into 5850 9 times, resulting in a remainder of 261.
Write down 9 as next digit of the result. 
Result so far: 3029.159
Subtract 5589 from 5850 to get 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

On to step 11:
When dividing 2610 by 621, we get 4 with a remainder of 126.
Use 4 as the next digit of our solution. 
Result so far: 3029.1594
Deduct 2484 from 2610 and we're left with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Moving on to step 12:
621 can be fit into 1260 2 times, resulting in a remainder of 18.
The next digit of our result is 2. 
Result so far: 3029.15942
If we subtract 1242 from 1260, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 13:
180 divided by 621 is 0 with a remainder of 180.
Record the quotient 0 as the next digit in the result. 
Result so far: 3029.15942
If we take 0 away from 180, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 14:
1800 divided by 621 is 2 with a remainder of 558.
Use 2 as the next digit of our solution. 
Result so far: 3029.1594202
Deduct 1242 from 1800 and we're left with 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Let's proceed to step 15:
621 can be fit into 5580 8 times, resulting in a remainder of 612.
Record the quotient 8 as the next digit in the result. 
Result so far: 3029.15942028
If we take 4968 away from 5580, we end up with 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

The quotient of the division is 3029.15942028, and the remainder is 6.12e-07.
